Item 9. Regulation FD Disclosure.

On December 18, 2003, we issued a press release entitled "Oceaneering Acquires
Medusa Spar Ownership Position."

The text of the press release is as follows:

             Oceaneering Acquires Medusa Spar Ownership Position

    HOUSTON, Dec. 18 /PRNewswire-FirstCall/ -- Oceaneering International, Inc.
(NYSE: OII) announced today that it has finalized its previously announced
investment of approximately $45 million to acquire a 50% ownership position in
Medusa Spar LLC, a limited liability company (LLC).  The LLC owns a 75%
undivided ownership position in the spar production platform moored in over
2,200 feet of water on the Medusa field in the Gulf of Mexico, Mississippi
Canyon Block 582.

    The other LLC owners are units of Murphy Oil Corporation (NYSE: MUR) and
Callon Petroleum Company (NYSE: CPE), with interests of 40% and 10%,
respectively.

    The LLC will earn a tariff based on the hydrocarbon production volume
throughput processed by the spar from the Medusa field and surrounding
dedicated blocks.  The LLC has no spar operating, maintenance, or repair cost
obligations and has obtained non-recourse financing for one-half of its
investment in the asset.  The loan to the LLC is secured by minimum throughput
guarantees from Murphy and Callon, which Oceaneering believes will be
sufficient to extinguish the debt.

    Oceaneering will account for its investment in the LLC and its share of
the LLC's results of operations using the equity method of accounting for
unconsolidated affiliates.

    John Huff, Chairman and Chief Executive Officer, stated, "The first of six
initial wells to be tied into the spar is now flowing, and according to Murphy
the other five are expected to be producing by the end of the third quarter,
2004.  The earnings contribution in 2004 and beyond will depend on the initial
six well production profiles and production from future wells that may be
drilled and tied into the spar.  During 2004 we expect the incremental net
income impact from our Medusa Spar investment to be in the range of $3.7 to
$5.0 million.

    "We believe the Medusa Spar, with a 20-year design life, will prove to be
an active production hub and a key asset in the deepwater infrastructure being
put in place in the Gulf of Mexico.  This will position us to participate in
other projects surrounding the spar and provide opportunities to market
Oceaneering's engineering and project management services, subsea hardware and
installation, maintenance, and repair services.  Oceaneering has commenced
work on the first of such projects, a subsea tie-back to the spar.

    "As a result of our LLC ownership position, we are increasing our estimate
of Oceaneering's 2004 EPS to a range of $1.55 to $1.60 from the $1.40 we
announced in our third quarter earnings release.  This revised EPS estimate
does not include the anticipated beneficial effects of the two pending ROV-
related acquisitions announced two weeks ago.  Consequently, we now believe
that it may be possible to achieve record EPS in 2004."

    Statements in this press release that express a belief, expectation or
intention, as well as those that are not historical fact, are forward looking.
The forward-looking statements in this press release include the statements
concerning:  the sufficiency of the throughput guarantee to extinguish the
LLC's non-recourse debt; Oceaneering's expectations with respect to the amount
of the LLC's impact on future earnings; future wells that may be tied into the
spar; Oceaneering's participation in other projects surrounding the spar;
opportunities to market Oceaneering's engineering and project management
services, subsea hardware and installation, maintenance, and repair services;
the estimated range of Oceaneering's 2004 EPS; and the expected earnings
impact of pending ROV-related acquisitions.  These forward-looking statements
are made pursuant to the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995 and are based on current information and
expectations of Oceaneering that involve a number of risks, uncertainties, and
assumptions.  Among the factors that could cause the actual results to differ
materially from those indicated in the forward-looking statements are industry
conditions and the amount and timing of the spar's production volume
throughput.  Should any of these risks or uncertainties materialize, or should
the assumptions underlying the forward-looking statements prove incorrect,
actual outcomes could vary materially from those indicated.  These and other
risks are more fully described in Oceaneering's periodic filings with the
Securities and Exchange Commission.

    Oceaneering 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's services and products are
marketed worldwide to oil and gas companies, government agencies, and firms in
