General Development of Business

Oceaneering International, Inc., (together with its subsidiaries,
"Oceaneering" or the "Company") is an advanced applied technology
company that provides engineered services and hardware to customers
who operate in marine, space and other harsh environments.  The
Company supplies a comprehensive range of integrated technical
services to a wide array of industries and is one of the world's
largest underwater services contractors.  Principal services are
provided to the oil and gas industry and include drilling support,
subsea construction, production systems, facilities maintenance and
repair, survey and positioning and specialized onshore and offshore
engineering and inspection.  Oceaneering was organized in 1969 out of
the combination of three diving service companies founded in the early
1960s.  Since its establishment, the Company has concentrated on the
development and marketing of underwater services requiring the use of
advanced deepwater technology.  The Company conducts operations in the
United States and 28 other countries.  The Company's international
operations, principally in the North Sea, Africa and Far East,
accounted for approximately 51% of its 1998 revenues, or $184 million.

Since 1990, the Company has concentrated on expanding its capabilities
to provide technical solutions to customers operating in harsh
environments.  It has accomplished this through acquisitions and
internal growth.

In January 1990, the Company acquired all of the outstanding capital
stock of Sonsub Limited, a United Kingdom company, whose principal
assets were ten work class Remotely Operated Vehicles ("ROVs").  ROVs
are unmanned submersible vehicles operated from the surface that are
used widely in the offshore oil and gas industry.

In December 1990, the Company was awarded a contract by a major oil
company to provide and maintain a Floating Production, Storage and
Offloading system ("FPSO").  This represented the first major project
for the Company's Offshore Production Systems division ("OPS"), which
was formed to develop economical production alternatives for offshore
oil and gas fields.  A 78,000 deadweight ton ("dwt") tanker was
purchased and converted into an FPSO, the OCEAN PRODUCER, for this
project.  The unit was delivered to its first location in December
1991 and is currently under contract for operations offshore West
Africa.

In August 1992, the Company acquired Eastport International, Inc.,
("Eastport"), a designer, developer and operator of advanced robotic
systems and ROVs specializing in the non-oilfield market, in a
transaction accounted for as a pooling of interests.  Eastport's
assets included two specialized ROVs, one of which is rated for water
depths to 25,000 feet, a deep tow sonar system and two other work
class ROVs.

In May 1993, the Company purchased the business and assets of the
Space Systems Division of ILC Dover, Inc., ("ILC") which were
consolidated with the Company's Oceaneering Space Systems division. 
This business designs, develops and fabricates spacecraft hardware and
high temperature insulation products.

In July 1993, the Company purchased Oil Industry Engineering, Inc., a
designer and fabricator of subsea control systems, which now operates
as the Oceaneering Intervention Engineering division ("OIE").  In
March 1994, the Company purchased the operating subsidiaries of
Multiflex International Inc., a manufacturer of subsea control
umbilical cables, which now operates as the Oceaneering Multiflex
division ("Multiflex").  Together with the Company's existing OPS
division, these acquisitions form the basis of the Company's
continuing expansion in the offshore field development business.

In November 1995, the Company was awarded a contract with a major oil
company for the provision of an FPSO.  The Company converted a 268,000
dwt tanker and delivered the unit to its first operational location
offshore West Africa in August 1996.  The customer exercised an option
to purchase the unit in December 1996 and the Company is currently
continuing to manage the vessel and to supervise major modifications
to increase the production capacity of the unit.

The Company intends to continue its strategy of acquiring, as
opportunities arise, additional assets or businesses, either directly
through merger, consolidation or purchase, or indirectly through joint
ventures.  The Company is also applying its skills and technology in
further developing business unrelated to the oil and gas industry and
performing services for government agencies and firms in the
telecommunications, aerospace, and civil engineering and construction
industries.  The Company is continually seeking opportunities for
business combinations to improve its market position or expand into
related service lines.

fiscal year.

Financial Information about Industry Segments

The Company's business segments are Oilfield Marine Services, Offshore
Field Development and Advanced Technologies.  The table containing
revenues, operating income, identifiable assets, capital expenditures,
and depreciation and amortization by business segment for the years
ended March 31, 1998, 1997 and 1996 is incorporated herein by
reference from Note 6 of the Notes to Consolidated Financial
Statements.

Description of Business

OILFIELD MARINE SERVICES

The Company's Oilfield Marine Services business consists of underwater
intervention and above-water inspection, maintenance and repair. 
These services may be provided to customers on an integrated basis.

Underwater Intervention Services.  The Company provides underwater
support services for all phases of offshore oil and gas operations -
exploration, development and production.  During the exploration
phase, the Company provides positioning, placement and monitoring of
subsea exploration equipment, collects data on seafloor
characteristics at proposed drilling sites and assists with the
navigational positioning of drilling rigs.  During the development
phase, the Company assists with the installation of production
platforms and the connection of subsea pipelines.  During the
production phase, the Company inspects, maintains and repairs offshore
platforms, pipelines and subsea equipment.

Underwater intervention services are performed by ROVs or divers. 
ROVs are used at depths or in situations in which diving would be
uneconomical or infeasible.  The Company believes that it operates the
largest and most technically advanced fleet of work class ROVs in the
world, with over 25% market share.  ROVs are used for a variety of
underwater tasks including drill support, installation and
construction support, pipeline inspections and surveys, and subsea
production facility installation, operation and maintenance.  An ROV
may be outfitted with manipulators, sonar, television cameras,
specialized tooling packages and other equipment or features to
facilitate the performance of specific underwater tasks.  The Company
currently owns more than 80 work class ROVs and is the industry leader
in providing ROV services on deepwater wells which are the most
technically demanding.

Prior to 1996, the Company purchased most of its ROVs from third-party
manufacturers although it designed and built specialized systems in
house.  In response to increased demand for more powerful systems
capable of operating in deeper water, the Company expanded its
production capabilities and established a dedicated facility to design
and build ROVs to meet the continued expansion of the ROV fleet.  Over
30 systems have been delivered and all new ROVs entering the Company's
fleet are now produced at this facility.

When a project requires manned intervention, the Company uses divers
or Atmospheric Diving Systems ("ADS") technology.  An ADS encloses the
operator in a one-atmosphere (surface pressure) diving suit and is
suitable for use in water depths to 2,300 feet.  The Company does not
use divers (as distinguished from ADS operators) to perform functions
in water depths greater than 1,000 feet.

The Company also provides a range of survey and navigational
positioning services for the oil and gas industry, as well as ocean
search and recovery projects.  Applications include surface
positioning for rig moves and the installation of pipelines and
platforms, subsea positioning and acoustics, geophysical surveys, deep
tow surveys and pipeline surveys.

Underwater services using all of these techniques are performed from
drilling rigs, platforms, barges and vessels.

Above-Water Inspection Services.  Through its Solus Schall division
("Solus Schall"), the Company offers a wide range of inspection
services to customers required to obtain third party inspections to
satisfy contractual structural specifications and requirements,
internal safety standards or regulatory requirements.  The Company
focuses on the inspection of pipelines and onshore fabrication of
offshore facilities for the oil and gas industry.  Certain of Solus
Schall's pipeline inspection activities are performed through the use
of specialized X-ray crawlers, which travel independently inside
pipelines, stopping to perform radiographic inspection of welds. 
Solus Schall derives the majority of its revenues from foreign
operations.

OFFSHORE FIELD DEVELOPMENT

Mobile Offshore Production Systems.  The Company established OPS as a
division during 1989 to provide subsea intervention services and the
engineering, procurement, construction, installation and operation of
mobile offshore production systems ("MOPS") to customers for marginal
and remote field production and extended well testing.  The Company
has been awarded several contracts pertaining to MOPS activities and
subsea workover and maintenance needs, including deepwater extended
well testing in the Gulf of Mexico and has served as prime contractor
on an extended well testing project in the North Sea.  The Company's
first FPSO, the OCEAN PRODUCER, has been operating offshore West
Africa since December 1991.  In December 1997, the Company purchased a
production barge which is under contract offshore Indonesia.  The
Company continues to operate the FPSO ZAFIRO PRODUCER under a
management agreement and is managing a major upgrade of the vessel. 
The ZAFIRO PRODUCER, which was acquired in 1996 and converted to an
FPSO, was delivered to its first location offshore West Africa in
August 1996 to begin operations under a three-year contract with a
major oil company.  The customer had an option to purchase the unit
and exercised this option in December 1996.  Additionally, the Company
owns four out-of-service offshore rigs and a tanker capable of
conversion to MOPS units.

Subsea Products.  OIE, Multiflex and the Pipeline Repair Systems unit
of the Company comprise the Subsea Products division which complements
the activities of OPS.  OIE provides subsea intervention services,
design and fabrication of ROV interface tooling, including ROV
replaceable and ROV operable valves, and design and fabrication of
subsea control systems.

Multiflex, with facilities in Houston, Texas and Edinburgh, Scotland,
produces subsea control umbilical cables which are used for the remote
operation of subsea installations and equipment and typically
incorporate both electrical and hydraulic control lines.

ADVANCED TECHNOLOGIES

The Company's Advanced Technologies ("ADTECH") business segment
provides underwater intervention, topside inspection, and engineering
services to meet a variety of non-oilfield industrial requirements,
including ship husbandry, search and recovery, subsea
telecommunications cable installation, maintenance and repair, civil
works projects and commercial theme park animation.  This is
accomplished in part by extending the use of existing assets and
technology developed in oilfield operations to new applications.

ADTECH performs work for customers having specialized requirements
underwater or in other environments.  ADTECH provides deep ocean
search and recovery services for governmental bodies, including the
U.S. Navy.  In other services for the Navy, ADTECH provides various
engineering and underwater services ranging from aircraft salvage and
recovery operations to inspection and maintenance of the Navy's fleet
of surface ships and submarines.  The Company also maintains and
operates deepwater cable lay and maintenance vehicles for Tyco
Submarine Systems Ltd.

ADTECH designs and operates ROVs that are rated for work in water
depths to 25,000 feet.  The Company's ROVs are equipped with umbilical
cords containing fiber optics which allow for improved communications
with the surface.  Other specialized equipment owned by the Company
includes ROV cable lay and maintenance equipment rated to 5,000 feet
and deep tow, side scan sonar systems rated for use in 20,000 feet. 
The Company's deep tow systems have been used to locate aircraft in
water depths to 14,700 feet.

ADTECH also designs and develops specialized tools and builds ROV
systems to customer specifications for use in deepwater and hazardous
environments.

As part of ADTECH, Oceaneering Space Systems ("OSS") directs the
Company's efforts towards applying undersea technology and experience
in the space industry.  The Company has worked with the National
Aeronautics and Space Administration ("NASA") and NASA subcontractors
on a variety of projects including portable life-support systems,
decompression techniques, tools and robotic systems, and standards and
guidelines to ensure robotic compatibility for space station equipment
and payloads.  OSS was expanded in 1994 by the purchase of the assets
of ILC.  ILC had supported NASA by producing space shuttle crew
support equipment, including the design, development and fabrication
of spacecraft extravehicular and intravehicular hardware and soft
goods, air crew life-support equipment, mechanical and
electromechanical devices and high temperature insulation.  These
activities have continued.  The activities of OSS are substantially
dependent on continued government funding for space programs.

MARKETING

Oilfield Marine Services.  The Company markets its services primarily
to international and foreign national oil and gas companies.  It also
provides services as a subcontractor to companies operating as prime
contractors. Contracts are typically awarded on a competitive bid
basis and are for the most part short-term.

Offshore Field Development.  The Company markets both its mobile
offshore production systems and subsea products primarily to
international and foreign national oil and gas companies, utilizing
the Company's existing administrative structure to identify potential
business opportunities.  MOPS are offered for extended well testing,
early production and development of marginal fields and prospects in
areas lacking pipelines and processing infrastructure.  Contracts are
typically awarded on a competitive basis, generally for periods of one
or more years.  The Company owns two MOPS units and operates a third. 
Further equipment will be added as profitable opportunities arise. 
The Company also owns equipment which is capable of conversion to
MOPS.  The Company believes that Multiflex enables it to identify
market opportunities at an earlier stage as umbilical design is
typically part of the initial planning phase in field development. 
The Company is able to offer an integrated service consisting of
design, engineering, project management and provision of hardware.

Advanced Technologies.  The Company markets its marine services and
related engineering services to government agencies, major defense
contractors, NASA subcontractors and to telecommunications,
construction and other industrial customers outside the energy sector. 
The Company also markets to insurance companies, salvage associations
and other customers who have requirements for specialized operations
in deep water.

Major Customers.  Five principal customers of the Company accounted
for approximately 26%, 33% and 29% of the Company's consolidated
revenues in  1998, 1997 and 1996, respectively.  No single customer
accounted for more than 10% of the Company's consolidated revenues in
1998 or 1996.  The Mobil Corporation group of companies accounted for
more than 10% of the Company's revenues in 1997.  Also see Note 6 of
the Notes to Consolidated Financial Statements.

COMPETITION

The Company's businesses are highly competitive.

Oilfield Marine Services.  The Company believes that it is one of five
companies that provides underwater services on a worldwide basis.  The
Company competes for contracts with the other four worldwide companies
and with numerous companies operating locally in various areas. 
Competition for underwater services historically has been based on the
type of underwater equipment available, location of or ability to
deploy such equipment, quality of service and price.  The relative
importance of these factors can vary from year to year based on market
conditions.  The ability to develop improved equipment and techniques
and to attract and retain skilled personnel is also an important
competitive factor in the Company's markets.  The number of the
Company's competitors is inversely correlated with water depth, as
less sophisticated equipment and technology is required in shallow
water.  With respect to projects that require less sophisticated
equipment or diving techniques, small companies have sometimes been
able to bid for contracts at prices uneconomic to the Company.

The Company believes that its ability to provide a wide range of
underwater services, including technological applications in deeper
water on a worldwide basis, should enable it to compete effectively in
the oilfield exploration and development market.  Oil and gas
exploration and development expenditures fluctuate from year to year. 
In particular, budgetary approval for more expensive drilling and
production in deeper water or harsh environments, areas in which the
Company believes it has a competitive advantage, may be postponed or
suspended.  In some areas, the ability of the Company to obtain
contracts depends upon its ability to charter vessels for use as work
platforms.  The Company will occasionally bid jointly with vessel
owners for service contracts.

The worldwide inspection market consists of a wide range of inspection
and certification requirements in many industries.  Solus Schall
competes in only selected portions of this market.  The Company
believes that its broad geographic sales and operational coverage,
long history of operations, technical reputation, application of X-ray
crawler pipeline radiography and accreditation to international
quality standards enable it to compete effectively in its selected
inspection services market segments.

Frequently, oil and gas companies utilize prequalification procedures
that reduce the number of prospective bidders for their projects.  In
certain countries, political considerations tend to favor local
contractors.

Offshore Field Development.  The Company believes that it is well
positioned to compete in the offshore field development market through
its ability to identify and offer optimum solutions, supply equipment,
provide capital on a limited basis and utilize the expertise in
associated subsea technology and offshore construction and operations
gained through its extensive operational experience worldwide.  The
Company is one of many companies that offer leased MOPS units.

Although there are several competitors offering either specialized
products or operating in limited geographic areas, the Company
believes that it is one of two companies that compete on a worldwide
basis for the provision of subsea control umbilical cables.

Advanced Technologies.  The Company believes that its specialized ROV
assets and experience in deep water operations give it a competitive
advantage in obtaining contracts in water depths greater than 5,000
feet.  The number of the Company's competitors is inversely correlated
with water depth, due to the advanced technical knowledge and
sophisticated equipment required for deep water operations.

Engineering services is a very broad market with a large number of
competitors.  The Company competes in specialized areas in which it
can combine its extensive program management experience, engineering
services and the capability to continue the development of conceptual
project designs into the manufacture of prototype equipment.

The Company also utilizes the administrative structure of the Oilfield
Marine Services business to identify opportunities in foreign
countries and to provide additional local support for non-oil and gas
customers.

SEASONALITY, BACKLOG AND RESEARCH AND DEVELOPMENT

A material amount of the Company's revenues is generated by contracts
for marine services in the Gulf of Mexico and North Sea, which are
usually seasonal from April through November.  However, the Company's
exit from the diving sector in the North Sea in early 1998 and the
substantial number of multi-year ROV contracts which have been entered
into since 1997 should reduce the seasonality of the Company's
Oilfield Marine Services operations.  Revenues in the Offshore Field
Development and Advanced Technologies segments are generally not
seasonal.

The amounts of backlog orders believed to be firm for Oilfield Marine
Services as of March 31, 1998 and 1997 were $180 million and $154
million, respectively.  Of these amounts, $59 million and $65 million,
respectively, were not expected to be performed within the year
following such respective dates.  At March 31, 1998 and 1997, the
Company had approximately $51 million and $64 million, respectively,
in backlog for Offshore Field Development.  Of these amounts, $10
million and $33 million, respectively, were not expected to be
performed within the year following such respective dates.  At March
31, 1998 and 1997, the Company had approximately $37 million and $31
million, respectively, in backlog for Advanced Technologies.  Of these
amounts, $2 million of the 1998 backlog was not expected to be
performed within the following year.

No material portion of the Company's business is subject to
renegotiation of profits or termination of contracts by the United
States government.

The Company's research and development expenditures were approximately
$4 million, $4 million and $6 million during 1998, 1997 and 1996,
respectively.  These amounts do not include, nor is the Company able
to determine, the expenditures by others in connection with joint
research activities in which the Company participated or expenditures
by the Company in connection with research conducted during the course
of performing its operations.


REGULATION

The Company's operations are subject to various types of governmental
regulation.  The Company's operations are affected from time to time
and in varying degrees by foreign and domestic political developments
and foreign, federal and local laws and regulations.  In particular,
oil and gas production operations and economics are affected by tax,
environmental and other laws relating to the petroleum industry, by
changes in such laws and by constantly changing administrative
regulations.  Such developments may directly or indirectly affect the
Company's operations and those of its customers.

Compliance with federal, state and local provisions regulating the
discharge of materials into the environment or relating to the
protection of the environment has not had a material impact on the
Company's capital expenditures, earnings or competitive position. 

In connection with its foreign operations, the Company is required in
some countries to obtain licenses or permits in order to bid on
contracts or otherwise to conduct business operations.  Some foreign
countries require that the Company enter into a joint venture or
similar business arrangement with local individuals or businesses in
order to conduct business.  While not a formal requirement, within the
Oilfield Marine Services segment, Oceaneering's quality management
systems covering the full range of subsea and topside services offered
in the United Kingdom are certified to the British Standard BS EN ISO
9001:1994 and the Norwegian office is certified to the Norwegian
Standard NS EN ISO 9001:1994, both of which are the equivalent of ISO
9001.  The quality management systems of both the OIE and Multiflex
units of the Offshore Field Development segment are certified to ISO
9001 for their products and services.  The quality systems of the
Space Systems and Oceaneering Technologies units of the Advanced
Technologies segment are certified to ISO 9001.

RISKS AND INSURANCE

The Company's operations are subject to all the risks normally
incident to offshore exploration, development and production,
including claims under U.S. maritime laws.  These risks could result
in damage to or loss of property, suspension of operations and injury
to or death of personnel.  The Company insures its real and personal
property and equipment.  The Company's vessels are insured against
damage or loss, including war and pollution risks.  The Company also
carries workers' compensation, maritime employer's liability, general
liability, including third party pollution, and other insurance
customary in its businesses.  All insurance is carried at levels of
coverage and deductibles which the Company considers financially
prudent.  On some contracts, the Company may have certain exposures
for loss or damage to the customer's facilities or for unexpected
weather delays, which the Company may cover by special insurance when
it deems advisable.  Due to the costs for limited coverage and, in the
Company's opinion, limited exposure, the Company does not ordinarily
carry professional liability insurance.  In some jurisdictions, legal
pleadings in personal injury actions may include a claim for an amount
of punitive damages which may not be covered by insurance.

The primary industry that the Company serves, oil and gas, is a
cyclical industry and remains volatile, resulting in potentially large
fluctuations in demand for the Company's primary services, which could
result in significant changes in the Company's revenues and profits. 
Although the oil and gas industry continues to be the Company's
principal market, the Company also performs services for government
agencies, and firms in the telecommunications, aerospace, and civil
engineering and construction industries.

The Company operates primarily as a services company under dayrate
contracts.  However, the Company also owns certain specialized capital
assets, which if not fully utilized could have a negative effect on
cash resources as a result of continuing fixed operating costs and
reduced revenues.

A significant part of the Company's operations is conducted outside
the United States.  For the years ended March 31, 1998, 1997 and 1996,
foreign operations accounted for 51%, 58% and 58% of the Company's
revenues, respectively.

Foreign operations are subject to additional political and economic
uncertainties, including the possibility of repudiation of contracts
and confiscation of property, fluctuations in currency exchange rates,
limitations on repatriation of earnings and foreign exchange controls.
Typically, the Company is able to limit the currency risks by
arranging compensation in United States dollars or freely convertible
currency and, to the extent possible, limiting acceptance of blocked
currency to amounts which match its expense requirements in local
currencies.

Certain of the countries in which the Company operates have enacted
exchange controls to regulate foreign currency exchange.  Exchange
controls in some of the countries in which the Company operates
provide for conversion of local currency into foreign currency for
payment of debts, equipment rentals, technology transfer, technical
assistance and other fees or repatriation of capital.  Transfers of
profits and dividends can be restricted or limited by exchange
controls.

EMPLOYEES

As of March 31, 1998, the Company had approximately 2,600 employees. 
The Company's work force varies seasonally and peaks during the summer
months.  Approximately 3% of the Company's employees are represented
by unions.  The Company considers its relations with its employees to
be satisfactory.

Item 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
          AND RESULTS OF OPERATIONS.

All statements in this Form 10-K, other than statements of historical
facts, including, without limitation, statements regarding the
Company's business strategy, plans for future operations, and industry
conditions, are forward-looking statements made pursuant to the safe
harbor provisions of the Private Securities Litigation Reform Act of
1995.  The Company utilizes a variety of internal and external data
and management judgment in order to develop such forward-looking
information.   Although the Company believes that the expectations
reflected in such forward-looking statements are reasonable, because
of the inherent limitations in the forecasting process, as well as the
relatively volatile nature of the industry in which the Company
operates, it can give no assurance that such expectations will prove
to have been correct.  Accordingly, evaluation of future prospects of
the Company must be made with caution when relying on forward-looking
information.

Liquidity and Capital Resources 

The Company considers its liquidity and capital resources adequate to
support its core business and internally generated growth initiatives. 
At March 31, 1998, the Company had working capital of $45 million,
including $7.6 million of unrestricted cash.  Additionally, the
Company had $26 million of its $80 million credit facility available
and $40 million was unused under uncommitted lines of credit.  The
Company is in the process of arranging $100 million of fixed-rate
long-term debt.

The Company is constructing two multi-service support vessels and is
continuing to expand its fleet of ROVs for use in the Oilfield Marine
Services segment.  In the Offshore Field Development segment, the
Company has also purchased equipment for use in production systems
projects and additional subsea product manufacturing facilities are
planned.

The Company expects operating cash flow to meet its ongoing annual
cash requirements, including debt service.  Net income plus
depreciation and amortization (commonly referred to as Cash Flow from
Operations) was $45 million for 1998 compared to $52 million and $33
million for 1997 and 1996, respectively.

Working capital at the end of 1998 was $45 million which compared to
$53 million at the end of 1997 and $42 million at the end of 1996. 
The increased cash flow and higher working capital in 1997 was a
result of the disposition of the FPSO ZAFIRO PRODUCER.

Capital expenditures for the years ended March 31, 1998, 1997 and 1996
were $94 million, $80 million and $57 million, respectively.

Capital expenditures in 1998 consisted of additions to the Company's
fleet of ROVs, construction costs for the two dynamically-positioned
("DP") multi-service support vessels in progress, the purchase of a
production barge operating in Southeast Asia, a tanker for possible
future conversion to production systems use, two out-of-service mobile
drilling platforms for potential conversion to production systems or
alternative service, and expenditures on leasehold improvements
related to the relocation and consolidation of Company office and
workshop facilities in the U.S.

Capital expenditures in 1997 included $38 million to complete the
conversion of the ZAFIRO PRODUCER.  Other expenditures consisted of
additions to the Company's fleet of ROVs and the purchase of two
support vessels.  Capital expenditures for 1996 included $30 million
of acquisition and conversion costs of the FPSO ZAFIRO PRODUCER,
completion of upgrades on two DP vessels and additions to the
Company's fleet of ROVs.

Commitments for capital expenditures at the close of 1998 were
approximately $40 million for completion of multi-service support
vessel construction and subsea product manufacturing facilities
expansion.

In 1996, the Company was awarded a contract by a major oil company to
provide an FPSO under a dayrate lease arrangement with an initial term
of three years which commenced on delivery of the FPSO in August 1996. 
The Company purchased and converted an existing 268,000 dwt crude oil
tanker into the FPSO ZAFIRO PRODUCER at a capital cost of $68 million. 
The contract provided the customer with the option to purchase the
vessel and terminate the lease at any time during the initial three-
year period and the customer exercised its purchase option in December
1996.  The Company utilized part of the proceeds to repay the debt
which had been incurred in conversion of the vessel.

In April 1997, the Company approved a plan to purchase up to a maximum
of 3 million shares of its Common Stock and 1.4 million shares were
purchased under this plan in 1998 at a total cost of $23 million.  The
Company expects to fund any additional purchases from existing
resources and operating cash flows.

At March 31, 1998, the Company had long-term debt of $55 million which
was equivalent to a 34% debt to equity ratio.  The debt was incurred
in the funding of capital expenditures and treasury stock purchases. 
As a result of the disposition of the FPSO ZAFIRO PRODUCER, the
Company fully repaid its long-term debt in December 1996 and had no
long-term debt at March 31, 1997.  The ratio of the Company's debt to
total capitalization will vary from time to time depending primarily
upon the level of capital spending.

Because of its significant foreign operations, the Company is exposed
to currency fluctuations and exchange risks.  The Company generally
minimizes these risks primarily through matching, to the extent
possible, revenues and expenses in the various currencies in which it
operates.  However, due to the weakness in certain Asian currencies
during 1998, the Company recognized $1.0 million of losses as Other
Expense.  Cumulative translation adjustments as of March 31, 1998,
relate primarily to the Company's permanent investment in and loans to
its United Kingdom subsidiary.  Inflation has not had a material
effect on the Company in the past two years and no such effect is
expected in the near future.

See Item 1 - "Business - Description of Business - Risks and
Insurance."  


Results of Operations

Revenues were $358 million for 1998 compared to $369 million for 1997
and $290 million  for 1996.  Gross margins were $75 million for 1998
compared to $78 million for 1997 and $55 million for 1996.  Gross
margin for 1997 included a gain on disposal of the FPSO ZAFIRO
PRODUCER of $25 million.  As a percentage of revenue, gross margin for
1998 was 21%, compared to 21% for 1997 and 19% for 1996.  Gross
margins as a percentage of revenues vary depending upon the mix of the
type of contracts (for example, subcontractor cost components) and may
not be indicative of business trends.  Net income in 1998 was $22.0
million, an increase of 13% over net income of $19.4 million in 1997,
which was over 50% higher than the $12.4 million reported for 1996.

Information on the Company's business segments is shown in Note 6 of
the Notes to Consolidated Financial Statements.

Oilfield Marine Services.

Revenues for the Oilfield Marine Services segment for 1998 were $182
million compared to $176 million in 1997 and $132 million in 1996. 
Income from operations for 1998 increased substantially to $16.3
million compared to $1.9 million in 1997 and a loss of $400,000 in
1996.

During 1997, in response to continued increasing demand to support
deepwater drilling and identified future construction and production
maintenance work, the Company extended its ROV fleet expansion program
begun in 1996 by announcing plans for over 30 additional new ROVs. 
These new vehicles are designed for use around the world in water
depths to 10,000 feet and in severe weather conditions.  This
expansion program was further extended in 1998 with the announcement
of plans to construct an additional 25 new ROVs.

In 1997, the Company also decided to discontinue offering diving
services in the North Sea.  Based on a review of actual and expected
operating results, the Company concluded that there would be a greater
return in focusing on other business lines in the North Sea area.  An
agreement was reached in March 1997 to sell its North Sea diving
assets, including a diving support vessel ("DSV").  The sale closed in
April 1997 and the sales proceeds approximated the net book value of
the assets sold.  Diving services continue to be offered by the
Company in other areas.

The table below sets out revenues and profitability for the Oilfield
Marine Services segment for 1998, 1997 and 1996.

                                     For the Years Ended March 31,
                                     1998        1997        1996

Revenues                         $ 181,800    $176,395    $132,064
Gross Margin                        40,064      24,139      21,154
Gross Margin %                         22%         14%         16%

Operating Income (loss)             16,263       1,853        (369)
Operating Income (loss) %               9%          1%          0%

For 1998, increased revenues in the U.S. were partially offset by
lower revenues in the North Sea, which was impacted by the Company's
exit from the diving business, resulting in an overall 3% increase in
revenues.  Gross margins increased to 22% in 1998 compared to 14% in
1997.  Gross margins in 1997 were reduced by an impairment adjustment
of $8.0 million which was made to reduce the carrying value of a DSV. 
Excluding the impairment adjustment, gross margin was 18% in 1997. 
The increase for 1998 reflected continued strong demand for ROV
services.  Additionally, diving profits improved on lower revenues.
 
Revenues increased 34% in 1997 compared to 1996, reflecting increased
activity in all operating areas.  Revenues and gross margin
contribution from the ROV fleet increased as requirements for vehicles
to support exploration and development drilling activities from
floating drilling rigs increased and units were added to the fleet.

Revenues and gross margin for 1996 benefitted by $1.1 million from the
settlement of a contract dispute which had been provided for in 1995. 
This adjustment increased gross margin percentage in 1996 by 1%.

Offshore Field Development.

This segment includes FPSO ownership and operations, engineering,
design and project management services for other MOPS-related work,
and subsea products.

The table below sets out revenues and profitability for this segment
for 1998, 1997 and 1996.

Revenues and margins for 1998 were lower than 1997 as a result of the
sale of the FPSO ZAFIRO PRODUCER, partially offset by higher project
management revenues and product sales.  Revenues and margins for 1997
include the results of operations for the ZAFIRO PRODUCER prior to its
purchase by the customer.  During 1997 the Company completed 
conversion of a 268,000 dwt tanker into an FPSO, the ZAFIRO PRODUCER,
which was delivered to a customer offshore West Africa in August 1996
under a three-year contract.  The customer had an option to purchase
the vessel at any time during the three-year contract period and
elected to do so in December 1996.  The Company recognized a gain of
$25.0 million on the disposition of this asset.  The Company is
continuing to operate the vessel under a management agreement and is
managing major upgrades to the vessel.

In December 1997, the Company purchased a production barge which is
contracted for work offshore Indonesia until October 1999.  The
Company also owns a tanker and four out-of-service mobile drilling
platforms which are being marketed for production systems or other
alternative use.

The Company's first FPSO, OCEAN PRODUCER, continued to work offshore
West Africa under a four-year contract expiring in January 2000. 
During 1997, the Company determined that substantial repairs would be
necessary to maintain the unit in operating condition in compliance
with regulatory requirements.  These repairs required a special
drydocking which was performed in 1998.  The Company recorded an $8.0
million provision in 1997 which reduced gross margin by 8%.

Results for 1996 also included a $2.7 million gain on the involuntary
conversion of the semisubmersible rig, OCEAN DEVELOPER, which sank in
August 1995 while under tow.

The Company expects to continue to invest in other MOPS assets as
profitable opportunities arise.


Advanced Technologies.

The table below sets out revenues and profitability for this segment
for 1998, 1997 and 1996.

                                    For the Years Ended March 31,
                                     1998        1997        1996
                                 (in thousands, except percentages)

Revenues                           $85,813     $91,350     $76,587
Gross Margin                        19,246      16,972      11,863
Gross Margin %                         22%         19%         15%

Operating Income                    12,424       9,514       4,988
Operating Income %                     14%         10%          7%

Revenues for 1998 declined as a result of lower telecommunications and
civil projects compared to 1997, partially offset by higher
engineering services activity.  Gross margins improved in 1998
compared to 1997 reflecting improved profitability on search and
recovery operations and higher demand for engineering services.

Revenues for search and recovery operations for 1997 were higher than
for 1996 as a result of increased activity in U.S. Navy support
although gross margin percentage was lower as a result of a higher
component of reimbursable costs. Subsea telecommunications cable
burial activities had higher revenues in 1997 than in 1996 and
improved gross margins.


Other.

Interest income declined in 1998 compared to 1997 as a result of lower
cash balances available for investment.  Interest expense declined in
1998 as a result of lower average borrowings and lower interest rates.
Interest income and interest expense for 1997 did not change
significantly from 1996.  Interest expense is net of capitalized
interest of $800,000 for 1998, $1.1 million for 1997 and $300,000 for
1996.

The Company's effective tax rate was 38%, 53% and 38% in 1998, 1997
and 1996, respectively.  The rate for 1997 was higher as a result of
provisions made for asset impairment and a special drydocking in its
United Kingdom subsidiary, where the Company derives no tax benefit as
it already has net operating loss carryforwards ("NOLs").


Year 2000. 

The Year 2000 problem is the result of computer programs which were
written using two digits rather than four to define the applicable
year.  Programs that have time sensitive software may recognize a date
using "00" as the year 1900 rather than the year 2000.  The Company 
has conducted a review of its computer systems to identify potential
problem areas.  Much of the cost of compliance is included in regular
system and equipment upgrades which are planned or are in progress. 
The Company does not expect the cost of compliance to have a material
effect on its financial position, results of operations or liquidity. 
However, there is no assurance that the systems of other companies on
which the Company relies will be converted timely and will not have an
adverse effect on the Company.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Oceaneering International, Inc.:

We have audited the accompanying consolidated balance sheets of
Oceaneering International, Inc. (a Delaware corporation) and
subsidiaries as of March 31, 1998 and 1997, and the related
consolidated statements of income, shareholders' equity and cash
flows for each of the three years in the period ended March 31,
1998.  These consolidated financial statements are the
responsibility of the Company's management.  Our responsibility is
to express an opinion on these financial statements based on our
audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial
position of Oceaneering International, Inc. and subsidiaries as of
March 31, 1998 and 1997, and the results of their operations and
their cash flows for each of the three years in the period ended
March 31, 1998, in conformity with generally accepted accounting
principles.

                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.        SUMMARY OF MAJOR ACCOUNTING POLICIES

  Principles of Consolidation

The consolidated financial statements include the accounts of
Oceaneering International, Inc., and its 50% or more owned and
controlled subsidiaries (the "Company").  The Company accounts for its
investments in unconsolidated affiliated companies under the equity
method.  All significant intercompany accounts and transactions have
been eliminated.  

Unless the context indicates otherwise, references to years indicate
fiscal year.

  Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and highly liquid
investments with original maturities of three months or fewer from the
date of the investment.  At March 31, 1998 and 1997 approximately $1.5
million of the Company's cash was restricted and is deposited in
interest bearing accounts as security in connection with legal
proceedings.

  Depreciation and Amortization

The Company provides for depreciation of Property and Equipment
primarily on the straight-line method over estimated useful lives of 3
to 12 years for marine services equipment, 10 years for mobile
offshore production equipment and 3 to 25 years for buildings,
improvements and other equipment.

The costs of repair and maintenance of Property and Equipment are
charged to operations as incurred, while the costs of improvements are
capitalized.  Upon the disposition of property and equipment, the
related cost and accumulated depreciation accounts are relieved and
the resulting gain or loss is included as an adjustment to cost of
services.

Goodwill arising from business acquisitions is amortized on the
straight-line method over 15 years.

Management periodically and upon the occurrence of a triggering event,
reviews the realizability of goodwill and other long-term assets and
makes any appropriate impairment adjustments and disclosures required
by generally accepted accounting principles.

Effective 1997, the Company adopted Statement of Financial Accounting
Standards Board standard number ("SFAS") 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of," as required.  SFAS 121 requires that certain long-lived
assets be reviewed for impairment whenever events indicate that the
carrying amount of an asset may not be recoverable and that an
impairment loss be recognized under certain circumstances in the
amount by which the carrying value exceeds the fair value of the
asset.  Initially, the adoption did not have a material effect on the
Company's results of operations or financial position.

During the third quarter of fiscal 1997 it became apparent that
operating results for the Company's diving support vessel ("DSV")
operating in the North Sea were below expectations.  The vessel was
originally acquired as a construction support vessel but changing
market conditions necessitated utilizing the vessel in an inspection
and maintenance mode at lower margins.  After review of the first full
work season the Company concluded that the manner in which the vessel
was being used had changed significantly from its originally intended
purpose and the recoverability of the carrying amount of the asset
should be assessed.  The Company determined that an impairment loss of
$8.0 million should be recorded.  The amount was determined by
comparing the carrying value of the vessel with the net present value
of the expected cash flows from the vessel over its remaining life. 
The impairment adjustment was recorded and included in the Company's
Oilfield Marine Services business segment.  Subsequently, the vessel
along with the other assets used in the North Sea diving operations
were sold and the sales proceeds approximated net book value.

  Revenue Recognition

The Company's revenues are primarily derived from billings under
contracts that provide for specific time, material and equipment
charges, which are accrued daily and billed monthly.  Significant
lump-sum contracts are accounted for using the
percentage-of-completion method.  Revenues on contracts with a
substantial element of research and development are recognized to the
extent of cost until such time as the probable final profitability can
be determined.  Anticipated losses on contracts, if any, are recorded
in the period that such losses are first determinable.

  Income Taxes

The Company accounts for income taxes according to SFAS 109,
"Accounting for Income Taxes".

  Foreign Currency Translation

All balance sheet asset and liability accounts of foreign subsidiaries
are translated into U.S. dollars at the rate of exchange in effect at
the balance sheet date.  Adjustments arising from these translations
are accumulated in a separate account within Shareholders' Equity. 
All income statement accounts are translated at average exchange rates
during the year.

  Earnings Per Share

The Company has computed earnings per share in accordance with
Financial Accounting Standards Board standard number ("SFAS") 128,
"Earnings Per Share", which became effective in the third quarter of
1998.  Prior periods comparative figures have been re-stated.

  Other Long-Term Liabilities

At March 31, 1998 and 1997 other long-term liabilities include $7.2
million and $8.0 million, respectively, for self-insurance reserves
not expected to be paid out in the following year and $7.2 and $7.8
million, respectively, for deferred income taxes.

  Reclassifications

Certain amounts from prior years have been reclassified to conform
with the current year presentation.

  Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of revenues
and expenses during the reporting period.  Actual results could differ
from those estimates.

  Property and Equipment

In 1997, a major oil company customer exercised its option to purchase
the Floating Production, Storage and Offloading system ("FPSO"),
ZAFIRO PRODUCER.  Upon disposition, the related property and equipment
cost and accumulated depreciation accounts were relieved and the
resulting gain of $25 million was included in the Company's
consolidated statement of income as Gain on Disposition of FPSO.

During the fourth quarter of 1997, the Company reached an agreement to
sell the assets of its North Sea diving business including its DSV
operating in the North Sea, various saturation and air diving systems
and related equipment.  Proceeds of $15 million, which were received
after the year end, were included in accounts receivable at the end of
1997.  Sales proceeds approximated net book value and impact on net
income was not material.


   New accounting pronouncements

The Financial Accounting Standards Board has issued SFAS 130,
"Reporting Comprehensive Income", and SFAS 131, "Disclosures about
Segments of an Enterprise and Related Information".  SFAS 130
establishes standards for reporting and display of comprehensive
income and its components.  The primary component of other
comprehensive income for the Company is the foreign currency
translation adjustment accounted for under SFAS 52.  SFAS 131
establishes standards for the way that public business enterprises
report information about operating segments in interim and annual
financial statements.  The Company will adopt SFAS 130 and SFAS 131 in
1999, as required.


2.        INCOME TAXES

The Company and its domestic subsidiaries, including acquired
companies from the respective dates of acquisition, file a
consolidated U.S. federal income tax return.  The Company conducts its
international operations in a number of locations which have varying
codes and regulations with regard to income and other taxes, some of
which are subject to interpretation.  Income taxes are provided at the
appropriate tax rates in accordance with the Company's interpretation
of the respective tax regulations after review and consultation with
its internal tax department, tax consultants and, in some cases, legal
counsel in the various jurisdictions.  Management believes that
adequate provisions have been made for all taxes which will ultimately
be payable.

Deferred income taxes are provided for temporary differences in the
recognition of income and expenses for financial and tax reporting
purposes.  The Company's policy is to provide for deferred U.S. income
taxes on unrepatriated foreign income only to the extent such income
is not to be invested indefinitely in the related foreign entity.

The provisions for income taxes for the years ended March 31, 1998,
1997 and 1996 were as follows:
                                             
                                     1998        1997        1996

As of March 31, 1998, the Company had net operating loss carryforwards
("NOLs") of approximately $29 million which are available to reduce
future United Kingdom Corporation Tax which would otherwise be
payable.

As of March 31, 1998 and 1997, the Company's worldwide deferred tax
assets and liabilities and related valuation reserves were as follows:

                                                    March 31,  
                                                 1998      1997

                                                ------    ------
          Net deferred tax assets              $ 3,391   $ 3,983
                                                ------    ------

          Deferred tax liabilities             $ 7,238   $ 7,784
                                                ------    ------

The Company's deferred tax assets consist of NOLs in its United
Kingdom subsidiary, which have no expiration date, and insurance claim
reserves for which a tax deduction has not yet been allowed.  Deferred
tax liabilities consist of depreciation and amortization and
provisions for income of foreign subsidiaries expected to be
repatriated.

The Company has established a valuation allowance for deferred tax
assets after taking into account factors that are likely to affect the
Company's ability to utilize the tax assets.  In particular, the
Company conducts its business through several foreign subsidiaries
and, although the Company expects its consolidated operations to be
profitable, there is no assurance that profits will be earned in
entities or jurisdictions which have NOLs available.  Since April 1,
1994, changes in the valuation allowance primarily relate to the
expected utilization of foreign NOLs and realization of foreign tax
credits.

Income taxes, computed by applying the federal statutory income tax
rate to income before income taxes and minority interests, are
reconciled to the actual provisions for income taxes as follows:

                                             For the Years Ended

The provision for 1997 includes the effect of provisions made for
asset impairment and special drydocking in its United Kingdom
subsidiary, where the Company derives no tax benefit as it already has
NOLs.


3.   DEBT

     Credit Agreement

On April 12, 1995, the Company and a group of banks signed a credit
agreement in the amount of $75 million (the "Credit Agreement").  As a
result of amendments, the present amount of and availability under
this agreement is $80 million.  There is a commitment fee of 0.225%
per annum on the unused portion of the banks' commitment.  At March
31, 1998 and 1997, there was $54 million and $0, respectively, of debt
outstanding under this agreement.

Under the Credit Agreement, the Company has the option to borrow
dollars through Euro-Dollar loans at the London Interbank Offered Rate
("LIBOR") plus 5/8%, certificate of deposit loans at the reserve
adjusted certificate of deposit rate plus 3/4%, or base rate loans at
the agent bank's prime rate.  The agreement contains certain
restrictive covenants relative to consolidated debt, tangible net
worth and fixed charge coverage.  Loans under the agreement are
unsecured.  Under the agreement, dividends may not exceed 50% of
cumulative consolidated net income from December 31, 1994.

The Company has uncommitted credit agreements with banks totaling $48
million for use for borrowings and letters of credit.  As of March 31,
1998, the Company had approximately $8 million in letters of credit
outstanding under these agreements.

Cash interest payments of $1.2 million, $3.6 million and $2.2 million
were made in 1998, 1997 and 1996, respectively.  Interest charges of
$800,000 in 1998, $1.1 million in 1997 and $300,000 in 1996 were
capitalized as part of construction in progress.


4.   EMPLOYEE BENEFIT PLANS AND STOCKHOLDER RIGHTS PLAN

     Retirement Investment Plans

The Company has three separate employee retirement investment plans
which cover its full-time employees.  The Oceaneering Retirement
Investment Plan is a deferred compensation plan in which domestic
employees may participate by deferring a portion of their gross
monthly salary and directing the Company to contribute the deferred
amount to the plan.  The Company matches a portion of the deferred
compensation.  The Company's contributions to the plan were
$1,960,000, $1,780,000 and $1,294,000 for the plan years ended
December 31, 1997, 1996 and 1995, respectively.  The second plan is
the Oceaneering International Services Pension Scheme for employees in
the United Kingdom.  During 1998, another plan for such employees, the
Personal Pension Plan, was converted to a Contracted in Money Purchase
Scheme within the Oceaneering International Services Pension Scheme. 
Under the combined plan, employees may contribute a portion of their
gross monthly salary.  The Company also contributes a portion of the
participants' gross monthly salary.  The plan assets exceed vested
benefits and are not material to the assets of the Company.  Company
contributions to this plan for the years ended March 31, 1998, 1997
and 1996 were $160,000, $202,000 and $172,000, respectively.

  During the first quarter of 1998, the third plan was the Oceaneering
International, Inc. Executive Retirement Plan, which covered selected
key management employees and executives of the Company.  The
participants in this plan contributed a portion of their gross monthly
salary and the Company matched 100% of that contribution.  Company
expense related to this plan during the years ended March 31, 1998,
1997 and 1996, was $576,000, $457,000 and $362,000, respectively. 
Effective June 30, 1997, the plan was terminated and replaced by a
Supplemental Executive Retirement Plan.  This plan also covers
selected key management employees and executives of the Company as
approved by the Compensation Committee of the Company's Board of
Directors ("Compensation Committee").  The Company accrues a portion
of the participants' gross monthly salary and the amounts accrued are
treated as if they are invested in one or more investment vehicles
pursuant to this plan.  Company expense related to this plan during
the year ended March 31, 1998 was $668,000.

     Incentive and Stock Option Plans

The Company has in effect shareholder approved nonemployee director
stock option and incentive plans.  Under the 1990 Nonemployee Director
Stock Option Plan ("Nonemployee Director Plan"), options to purchase
up to an aggregate of 100,000 shares of the Company's Common Stock may
be granted to nonemployee directors of the Company.  Each director of
the Company is automatically granted an option to purchase 2,000
shares of Common Stock on the date the director becomes a nonemployee
director of the Company and each year thereafter at an exercise price
per share equal to 50% of the fair market value of a share of Common
Stock on the date the option is granted.  The options granted are not
exercisable until the later to occur of six months from the date of
grant or the date the optionee has completed two years of service as a
director of the Company.  Expense is recorded related to these options
which have an exercise price less than fair market value on the date
the option is granted.  Expense in 1998, 1997 and 1996 was not
material.

In August 1996 the shareholders of the Company approved a 1996
Incentive Plan under which a total of 1,165,000 shares of Common Stock
of the Company were made available for awards to employees and other
persons (excluding nonemployee directors) having an important business
relationship or affiliation with the Company.  The 1996 Incentive Plan
and a similar shareholder approved 1990 Incentive Plan ("Incentive
Plans") are administered by the Compensation Committee, which
determines the type or types of award(s) to be made to each
participant and sets forth in the related award agreement the terms,
conditions and limitations applicable to each award.  The Compensation
Committee may grant stock options, stock appreciation rights, stock
and cash awards.  Options are normally granted at not less than fair
market value of the optioned shares at the date of grant.  Options
outstanding are exercisable over a period of five or ten years after
the date of grant or five years after the date of vesting at the rate
of 20% per year for three years beginning one year after grant and 40%
at the end of the fourth year, or 25% per year for four years
beginning one year after grant.  

The Company also has in effect one other stock plan under which
options to purchase have been issued to employees and other persons
affiliated with the Company.  Since approval of the 1990 Incentive
Plan, no further grants or awards under this stock plan have been made
or can be made or granted.  This stock plan is also administered by
the Compensation Committee.  Options were granted at not less than the
fair market value of the optioned shares at the date of grant. 
Options outstanding under this plan which were granted in 1990, are
exercisable over a ten-year term with vesting at the rate of 20% per
year for three years beginning one year after the date of grant and
40% at the end of the fourth year. 

During 1996 and 1997, the Compensation Committee granted to certain
key executives of the Company restricted Common Stock of the Company
designed (i) to make a material portion of their potential future
compensation contingent on performance of the Company's Common Stock
and (ii) to retain their employ with the Company.  These grants are
subject to earning requirements on the basis of a percentage change
between the price of the Common Stock of the Company versus the
average of the Common Stock price of a peer group of companies over a
three-year time period.  Up to one-third of the total grant made in
1997 may be earned each year depending upon the Company's cumulative
Common Stock performance, with any amount earned subject to vesting in
four equal installments over a three or four year period conditional
upon continued employment.  At the time of each vesting, a participant
receives a tax assistance payment which the participant must reimburse
the Company if the vested Common Stock is sold by the participant
within three years after the vesting date.  In 1998, no such
restricted stock grants were made.  As of March 31, 1998, the entire
grant made in 1996 has been earned, subject to vesting requirements,
and one-third of the grant made in 1997 was earned, subject to vesting
requirements.  As of March 31, 1998, a total of 373,250 shares of
restricted stock was outstanding under these and former, similar
grants, of which 177,250 shares were earned, subject to vesting
requirements.  In April 1997 certain key executives also elected to
receive restricted Common Stock of the Company totaling 44,968 shares
with a grant date fair value of $14.63 per share, subject to similar
vesting requirements and tax assistance payments, in lieu of cash for
all or part of their 1997 bonus award.  The numbers and weighted
average grant date fair value of restricted stock granted during 1997
and 1996 were 312,000 and $17.00, and 7,000 and $10.38, respectively.

The Company accounts for stock options issued under plans under APB
Opinion No. 25, under which no compensation cost has been recognized. 
Had compensation cost for these stock options been determined
consistent with SFAS 123 "Accounting for Stock-Based Compensation",
the Company's pro forma net income and diluted earnings per share for
1998, 1997 and 1996 would have been $21,373,000, $19,170,000 and
$12,357,000 respectively, and $0.92, $0.80 and $0.53, respectively. 
Because the SFAS 123 method of accounting has not been applied to
options issued prior to April 1 1995, the resulting pro forma
compensation cost may not be representative of that to be expected in
future years.

Information regarding these option plans for 1998, 1997 and 1996 is as
follows:

The weighted average fair value of options granted in 1998 and 1997
was $9.20 and $8.73, respectively.  No significant grants were made in
1996.  The fair value of the stock options granted in 1998 and 1997
was estimated on the date of grant using the Black-Scholes option
pricing model with the following assumptions:

                                        1998       1997

At March 31, 1998, there were 511,300 shares under these plans
available for grant, of which 469,000 could be used for awarding stock
options, stock appreciation rights, stock and cash awards to
employees.

     Stockholder Rights Plan

On November 20, 1992, the Company's Board of Directors adopted a
Stockholder Rights Plan and, in accordance with such Plan, declared a
dividend of one preferred share purchase right for each outstanding
share of Company common stock.  The Plan will cause substantial
dilution to a party that attempts to acquire the Company in a manner
or on terms not approved by the Board of Directors, except pursuant to
an offer conditioned on a substantial number of rights being acquired.

The rights, which do not have voting rights and are not entitled to
dividends until such time as they become exercisable, expire in
December 2002.


5.   COMMITMENTS AND CONTINGENCIES

     Lease Commitments

At March 31, 1998, the Company occupied several facilities under
noncancellable operating leases expiring at various dates through

Rental expense, which includes hire of vessels, specialized equipment
and real estate rental, was approximately $19 million, $25 million and
$19 million for the years ended March 31, 1998, 1997 and 1996,
respectively.

     Insurance

The Company self-insures for workers' compensation, maritime
employer's liability and comprehensive general liability claims to
levels it considers financially prudent and carries insurance after
the initial claim levels, which can be by occurrence or in the
aggregate, are met by the Company.  The Company determines the level
of accruals by reviewing its historical experience and current year
claim activity; accruals are not recorded on a present value basis. 
Each claim is reviewed with insurance adjusters and specific reserves
are established for all known liabilities.  An additional reserve for
incidents incurred but not reported to the Company is established for
each year using management estimates and based on prior experience. 
Management believes that adequate accruals have been established for
expected liabilities arising from such obligations.

     Litigation

Various actions and claims are pending against the Company, most of
which are covered by insurance.  In the opinion of management, the
ultimate liability, if any, which may result from these actions and
claims will not materially affect the financial position or results of
operations of the Company.

     Letters of Credit

The Company had $8.0 million and $7.3 million in letters of credit
outstanding as of March 31, 1998 and 1997, respectively, as guarantees
in force for various performance and bid bonds which are usually for a
period of one year or the duration of the contract.

     Financial Instruments and Risk Concentration

Financial instruments which potentially subject the Company to
concentrations of credit risk are primarily cash and cash equivalents,
bank borrowings and accounts receivable.  The carrying value of cash
and cash equivalents and bank borrowings approximates fair value due
to the short maturity of those instruments.  Accounts receivable are
generated from a broad and diverse group of customers primarily from
within the energy industry, which is the Company's major source of
revenues.  The Company maintains an allowance for doubtful accounts
based upon expected collectibility.

Income from operations for each business segment is determined before
interest income or expense, other expense, minority interests and the
provision for income taxes.  An allocation of these items is not
considered practical.  All assets specifically identified with a
particular business segment have been segregated.  Cash and cash
equivalents, prepaid expenses and other current assets, investments
and certain other assets have not been allocated to particular
business segments.  Income from operations for 1997 for Oilfield
Marine Services is after charging an impairment adjustment of $7,980
which is included in depreciation and amortization expense.  Income
from operations for Offshore Field Development for 1997 includes a
$25,047 gain on disposition of an FPSO and an $7,980 provision for a
special drydocking.

No individual customer accounted for more than 10% of revenues in 1998
or 1996.  Revenues of approximately $44 million in 1997 were from the
Mobil Corporation group of companies.

OCEANEERING INTERNATIONAL, INC.
1998 BONUS AWARD PLAN

The 1998 Bonus Award Plan is approved by the Company's Board of Directors and 
administered by its Compensation Committee.  Individuals who are nominated and 
approved for inclusion in the Plan will be reviewed after final year end 
results are completed.  Recommendations for cash bonus awards will be based on 
the accomplishment of results (Individual, Profit Center and Total Company) in 
order to determine the amount of award, if any, to be made.  People must be 
amongst the nominated group for eligibility, and be employed by the Company at 
the time of funding.  Bonuses will be earned when paid.  Individuals, as 
designated, will be subject to a maximum bonus eligibility of 10% - 100% of 
current base salary.

The 1998 Bonus Award Plan is based on achieving specific results by the 
Individual, his Profit Center and the Total Company.  In order to integrate 
each of these performances in a fashion that benefits the Shareholders and 
Employees, each item is interrelated.  The amount of award recommendation will 
be based on the following methodology:

Individual Coefficient

The Individual Coefficient is determined by taking the individual's weighted 
average evaluation of objectives achieved times the individual's salary 
maximum.  This is the beginning step in determining the final award.  An 
individual's performance must meet certain minimum criteria or he is 
eliminated from bonus award consideration.

Profit Center Results Contribution

The Profit Center Contribution is determined by comparing the Profit Center 
Net Income Objective with the results achieved and determining the 
Contribution to the Individual Coefficient.

Should the Profit Center results be below a specified amount, all the 
individuals in that Profit Center may be eliminated from the Award Program.  
The President may review the performance of areas within the region on a 
case-by-case basis and take appropriate action.  Should the actual results be 
equal to or greater than such specified amount, the individual becomes 
eligible for an award.

Oceaneering International, Inc. Results Contribution

The Company Results Contribution is determined by comparing the Company's FY98 
Net Income Result with the Objective planned.  The results achieved determine 
the multiplier that will be used.  Thus, an individual may, subject to the 
determined maximum, be recommended for an award equal to the Individual 
Coefficient times the Profit Center Contribution times the Company Results 
Contribution times current base salary.

Participants in the 1996 Restrictive Stock Incentive Program have the option 
to receive any bonus subsequently awarded by the Compensation Committee under 
the 1998 Bonus Award Plan in cash, cash and restricted stock or restricted 
stock.   Any restricted stock would be awarded pursuant to all terms and 
conditions, including vesting and tax assistance payments of the 1996 
Restricted Stock Incentive Program, except that one-quarter of such restricted 
amount would vest at the time of the bonus award and the remainder would vest 
in equal installments at the end of each of the following three years in 
accordance with agreement. 

The 1998 Bonus Award Plan is in effect FY98.  A similar plan may or may not be 
approved for FY99.  It is extremely important that the Company continue 
improved results in FY98.  All participants must be committed to a reward 
system based on achieving results.  The Company is entrepreneurially oriented 
and must use its maximum creativity, effort and determination in achieving 
individual results that collectively increases its Shareholders' Net Wealth.  
The 1998 Bonus Award Plan is structured to foster that position.
