                                EXPLANATORY NOTE

       This Registration Statement contains two forms of prospectus: one to be
used by the Company in connection with the issuance and sale from time to time
by the Company of shares of Common Stock in connection with its acquisition of
the securities or assets of other businesses (the "Company Prospectus") and one
to be used principally by persons who have received shares of Common Stock of
the Company in connection with acquisitions by the Company of securities or
assets held by such persons, or their transferees, and who wish to offer and
sell such shares in transactions in which they and any broker-dealer through
whom such shares are sold may be deemed to be Underwriters within the meaning
of the Securities Act (the "Selling Stockholders Prospectus").  The Company
Prospectus and the Selling Stockholders Prospectus will be identical in all
respects except that they will contain different front and back cover pages and
the Selling Stockholders Prospectus will contain an additional section under
the caption "Manner of Offering."  The Company Prospectus is included herein
and is followed by those pages to be used in the Selling Stockholders
Prospectus which differ from, or are in addition to, those in the Company
Prospectus.  Each of the alternate or additional pages for the Selling
Stockholders Prospectus included herein has been labeled "Alternate Page for
Selling Stockholders Prospectus."  If required pursuant to Rule 424(b) of the
General Rules and Regulations under the Securities Act, ten copies of each of
the prospectuses in the forms in which they are used after this Registration
Statement becomes effective will be filed with the Commission.

        Information contained herein is subject to completion or amendment. A  
registration statement relating to these securities has been filed with the
Securities and Exchange Commission.  These securities may not be sold nor
may offers to buy be accepted prior to the time the registration statement
becomes effective.  This prospectus shall not constitute an offer to sell or
the solicitation of an offer to buy nor shall there be any sale of these
securities in any state in which  such offer, solicitation or sale would be
unlawful prior to registration or qualification under the securities
laws of any such state.

                               ________________

       This Prospectus relates to 4,000,000 shares of common stock, par value
$0.01 per share (the "Common Stock"), of Diamond Offshore Drilling, Inc., a
Delaware corporation (the "Company"), which may be offered and issued from time
to time by the Company in connection with its acquisition of the securities or
assets of other businesses.  It is expected that the terms of acquisitions
involving the issuance and sale by the Company of Common Stock covered by this
Prospectus will be determined by direct negotiations with the owners or
controlling persons of the businesses whose securities or assets are acquired.
The Company expects that the shares of Common Stock issued in exchange for
securities or assets in business combination transactions will be valued at
prices reasonably related to market prices of the Common Stock either at the
time the terms of an acquisition are agreed upon or at or about the time of
delivery of such shares of Common Stock.

       The Registration Statement of which this Prospectus is a part also
relates to the offer and sale of Common Stock from time to time by persons who
have received shares of Common Stock in connection with acquisitions by the
Company of securities or assets held by such persons, or their transferees, and
who wish to offer and sell such shares in transactions in which they and any
broker-dealer through whom such shares are sold may be deemed to be
Underwriters within the meaning of the Securities Act of 1933, as amended (the
"Securities Act").

       All expenses of the offering by the Company hereby will be paid by the
Company.  No underwriting discounts or commissions will be paid in connection
with the issuance of Common Stock, although finder's fees may be paid with
respect to specific acquisitions.  Any person receiving a finder's fee may be
deemed to be an Underwriter within the meaning of the Securities Act.

       The Common Stock is listed on the New York Stock Exchange (the "NYSE")
under the symbol "DO."  On March 17, 1997, the closing price of the Common
Stock on the NYSE was $66.25 per share.

                               ________________

         THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
                SECURITIES AND EXCHANGE COMMISSION OR ANY STATE

                            IS A CRIMINAL OFFENSE.

(1)      The Company acquired all of the common stock of Arethusa (Off-Shore)
         Limited in consideration of 17.9 million shares of Common Stock
         effective April 29, 1996.  See Note 2 to the Company's Consolidated
         Financial Statements in Item 8 of the 1996 Annual Report.

(2)      The Company acquired all of the common stock of Odeco Drilling Inc.
         for approximately $376.6 million in cash effective January 1, 1992.

(3)      Effective January 1, 1996 and 1993, the Company revised the estimated
         useful lives for certain classes of its offshore drilling rigs.  The
         estimated useful lives of the Company's offshore drilling rigs, after
         the change in estimate, range from 10 to 25 years.  As compared to the
         original estimate of useful lives, this change resulted in a reduction
         of approximately $8.5 million and $6.3 million in depreciation expense
         during 1996 and 1993, respectively, and a corresponding increase in
         operating income.

(4)      Prior to the initial public offering of the Company's Common Stock in
         October 1995 (the "Common Stock Offering"), the Company was included
         in the consolidated U.S. federal income tax return of Loews
         Corporation ("Loews").  Effective January 1, 1992, a tax sharing
         agreement with Loews was adopted to allow for the recognition of
         expenses and benefits related to taxable income and losses as if the
         Company filed a separate consolidated return.  In conjunction with the
         Common Stock Offering, the tax sharing agreement was terminated and
         all assets and liabilities were settled by offsetting these amounts
         against notes payable to Loews.  For taxable periods subsequent to the
         Common Stock Offering, the Company has filed a consolidated U.S.
         federal income tax return on a stand-alone basis.

(5)      Pro forma net income per share gives effect to the Common Stock
         Offering and the after-tax effects of a reduction in interest expense.
         Assuming the Common Stock Offering had occurred at January 1, 1995,
         the Company would have recognized net income of $10.0 million, or
         $0.20 per share of Common Stock, after adjusting for the after-tax
         effects of a reduction in interest expense.  See Note 1 to the
         Company's Consolidated Financial Statements in Item 8 of the 1996
         Annual Report.

(6)      In addition to these capital expenditures, the Company expended $550.7
         million in equity consideration and $25.0 million, $10.6 million, and
         $410.9 million in cash for rig acquisitions during the years ended
         December 31, 1996, 1994, 1993, and 1992, respectively.  No amounts
         were expended for rig acquisitions during the year ended December 31,
         1995.

(7)      EBITDA (operating income (loss) plus depreciation minus gain on sale
         of assets) is a supplemental financial measure used by the Company in
         evaluating its business and should be read in conjunction with all of
         the information in the Selected Financial Data as well as the
         Company's Consolidated Financial Statements (including the Notes
         thereto) included in Item 8 of the 1996 Annual Report prepared in
         accordance with generally accepted accounting principles.  EBITDA
         should not be considered as an alternative to operating income (loss)
         or cash flow from operations as an indication of the Company's
         performance or as a measure of liquidity.

(8)      See the Company's Consolidated Financial Statements (including the
         Notes thereto) in Item 8 of the 1996 Annual Report.

(9)      The deficiency in the Company's earnings available for fixed charges
         for the years ended December 31, 1995, 1994, 1993 and 1992 was
         approximately $13.8 million, $46.4 million, $21.7 million, and $78.0
         million.  Fixed charges for the years ended December 31, 1992 through
         December 31, 1995 consisted primarily of interest expense on notes
         payable to Loews.  For all periods presented, the ratio of earnings to
         fixed charges has been computed on a total enterprise basis.  Earnings
         represent income (loss) from continuing operations plus income taxes
         and fixed charges.  Fixed charges represent interest, whether expensed
         or capitalized.

(10)     Long-term debt consisted solely of notes payable to Loews for the
         years ended December 31, 1994, 1993 and 1992.

(11)     In connection with the Common Stock Offering, the Company paid a
         special dividend of $2.1 million to Loews with a portion of the
         proceeds.  No other cash dividends were paid during the periods
         presented.

              [ALTERNATE PAGE FOR SELLING STOCKHOLDERS PROSPECTUS]



                               MANNER OF OFFERING


         This Prospectus, as appropriately amended or supplemented, may be used
from time to time principally by persons who have received shares of Common
Stock in connection with acquisitions by the Company of securities or assets
held by such persons, or their transferees, and who wish to offer and sell such
shares (such persons are herein referred to as "Selling Stockholders") in
transactions in which they and any broker-dealer through whom such shares are
sold may be deemed to be Underwriters within the meaning of the Securities Act.
The Company will receive none of the proceeds from any such sales.  Except as
described under "Selling Stockholders," there presently are no arrangements or
understandings, formal or informal, pertaining to the distribution of the
shares of Common Stock described herein.  Upon the Company being notified by a
Selling Stockholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares of Common Stock bought through a block
trade, special offering, exchange distribution or secondary distribution, a
supplemented Prospectus will be filed, pursuant to Rule 424(b) under the
Securities Act, setting forth (i) the name of each Selling Stockholder and the
participating broker-dealer(s), (ii) the number of shares involved, (iii) the
price at which the shares were sold, (iv) the commissions paid or the discounts
allowed to such broker-dealer(s), where applicable, (v) that such broker-
dealer(s) did not conduct any investigation to verify the information set out
in this Prospectus and (vi) other facts material to the transaction.

         Selling Stockholders may sell the shares being offered hereby from
time to time in transactions (which may involve crosses and block transactions)
on the NYSE, in negotiated transactions or otherwise, at market prices
prevailing at the time of the sale or at negotiated prices.  Selling
Stockholders may sell some or all of the shares in transactions involving
broker-dealers, who may act solely as agent and/or may acquire shares as
principal.  Broker-dealers participating in such transactions as agent may
receive commissions from Selling Stockholders (and, if they act as agent for
the purchaser of such shares, from such purchaser), such commissions computed
in appropriate cases in accordance with the applicable rules of the NYSE, which
commissions may be at negotiated rates where permissible under such rules.
Participating broker- dealers may agree with Selling Stockholders to sell a
specified number of shares at a stipulated price per share and, to the extent
such broker-dealer is unable to do so acting as an agent for the Selling
Stockholder, to purchase as principal any unsold shares at the price required
to fulfill the broker- dealer's commitment to Selling Stockholders.  In
addition or alternatively, shares may be sold by Selling Stockholders and/or by
or through other broker- dealers in special offerings, exchange distributions
or secondary distributions pursuant to and in compliance with the governing
rules of the NYSE, and in connection therewith commissions in excess of the
customary commission prescribed by such governing rules may be paid to
participating broker-dealers or, in the case of certain secondary
distributions, a discount or concession from the offering price may be allowed
to participating broker-dealers in excess of the customary commission.
Broker-dealers who acquire shares as principal may thereafter resell such
shares from time to time in transactions (which may involve crosses and block
transactions and which may involve sales to or through other broker-dealers,
including transactions of the nature described in the preceding two sentences)
on the NYSE, in negotiated transactions or otherwise, at market prices
prevailing at the time of sale or at negotiated prices, and in connection with
such resales may pay to or receive commissions from the purchaser of such
shares.

         The Company may agree to indemnify each Selling Stockholder as an
Underwriter under the Securities Act against certain liabilities, including
liabilities arising under the Securities Act.  Each Selling Stockholder may
indemnify any broker-dealer that participates in transactions involving sales
of the shares against certain liabilities, including liabilities arising under
the Securities Act.

         The Selling Stockholders may resell the shares offered hereby only if
such securities are qualified for sale under applicable state securities or
"blue sky" laws or exemptions from such registration and qualification
requirements are available.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 102 of the Delaware General Corporation Law ("DGCL") allows a
corporation to eliminate the personal liability of directors of a corporation
to the corporation or to any of its stockholders for monetary damage for a
breach of his fiduciary duty as a director, except in the case where the
director breached his duty of loyalty, failed to act in good faith, engaged in
intentional misconduct or knowingly violated a law, authorized the payment of a
dividend or approved a stock repurchase in violation of Delaware corporate law
or obtained an improper personal benefit.  The Company's Certificate of
Incorporation contains a provision which, in substance, eliminates directors'
personal liability as set forth above.

         Section 145 of the DGCL provides that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was a director, officer, employee or agent of the corporation or is or was
serving at its request in such capacity in another corporation or business
association against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.  The
Company's Certificate of Incorporation contains a provision which, in
substance, provides for indemnification as set forth above.

ITEM 22. UNDERTAKINGS

         The Company hereby undertakes:

         (1)     To file, during any period in which offers or sales are being
made of the securities registered hereby, a post-effective amendment to this
Registration Statement:

                 (i)      to include any prospectus required by Section
         10(a)(3) of the Securities Act of 1933;

                 (ii)     to reflect in the prospectus any facts or events
         arising after the effective date of this Registration Statement (or
         the most recent post-effective amendment thereof) which, individually
         or in the aggregate, represent a fundamental change in the information
         set forth in the Registration Statement.  Notwithstanding the
         foregoing, any increase or decrease in volume of securities offered
         (if the total dollar value of securities offered would not exceed that
         which was registered) and any deviation from the low or high end of
         the estimated maximum offering range may be reflected in the form of
         prospectus filed with the Commission pursuant to Rule 424(b) if, in
         the aggregate, the changes in volume and price represent no more than
         a 20% change in the maximum aggregate offering price set forth in the
         "Calculation of Registration Fee" table in the effective Registration
         Statement; and

                  (iii)   to include any material information with respect to
         the plan of distribution not previously disclosed in the Registration
         Statement or any material change to such information in the
         Registration Statement;

provided, however, that the undertakings set forth in clauses (i) and (ii)
above do not apply if the information required to be included in a
post-effective amendment by those clauses is contained in periodic reports
filed with or furnished to the Commission by the Company pursuant to Section 13
or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this Registration Statement;

         (2)     That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof;

         (3)     To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering;

         (4)     That, for purposes of determining any liability under the
Securities Act of 1933, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in this Registration Statement shall be deemed to be
a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof; and

         (5)     (a)      That prior to any public reoffering of the securities
registered hereunder through use of a prospectus which is a part of this
Registration Statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), the issuer undertakes that such
reoffering prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.

                 (b)      The registrant undertakes that every prospectus:  (i)
that is filed pursuant to paragraph (a) immediately preceding, or (ii) that
purports to meet the requirements of Section 10(a)(3) of the Securities Act and
is used in connection with an offering of securities subject to Rule 415, will
be filed as a part of an amendment to the registration statement and will not
be used until such amendment is effective, and that, for purposes of
determining any liability under the Securities Act, each such post-effective
amendment shall be deemed to be a new registration





                                      II-2
<PAGE>   15





statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Company pursuant to the provisions described under Item 15
above, or otherwise, the Company has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

         The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the Prospectus pursuant
to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through
the date of responding to the request.

         The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

Diamond Offshore Drilling, Inc.
15415 Katy Freeway
Houston, Texas 77094

Ladies and Gentlemen:

                 We have acted as counsel to Diamond Offshore Drilling, Inc., a
Delaware corporation (the "Company"), in connection with the preparation and
filing by the Company of a Registration Statement on Form S-4 (the
"Registration Statement") under the Securities Act of 1933, as amended (the
"Act"), pertaining to the issuance by the Company from time to time of up to
4,000,000 shares (the "Shares") of common stock, par value $.01 per share, of
the Company (the "Common Stock"), in connection with the acquisition of the
securities or assets of other businesses.

                 In so acting, we have examined originals or copies, certified
or otherwise identified to our satisfaction, of the Company's Restated
Certificate of Incorporation (the "Certificate"), the resolutions adopted by
the Board of Directors of the Company authorizing the filing of the
Registration Statement (the "Resolutions") and such other corporate records,
agreements, documents and other instruments, and such certificates or
comparable documents of public officials and of officers and representatives of
the Company, and have made such inquiries of such officers and representatives,
as we have deemed relevant and necessary as a basis for the opinions
hereinafter set forth.

                 In such examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such latter documents.  As to all questions of
fact material to this opinion that have not been independently established, we
have relied upon certificates or comparable documents of officers and
representatives of the Company.

                 Based on the foregoing, and subject to the qualifications
stated herein, we are of the opinion that:

                 1.       The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware.

                 2.       Upon the adoption by the Board of Directors of the
Company of the Resolutions authorizing the issuance and sale of the Shares, the
Shares will be duly authorized and, when issued and delivered to the
purchaser(s) thereof against payment therefor, will be validly issued, fully
paid and non-assessable.





                                Exhibit 5.1 - 1
<PAGE>   2
