      On a comparable basis for the second quarter of 2002, Oceaneering reported
revenues of $141.6 million and net income of $10.9 million, or $0.44 per share.
The year-over-year quarterly decline in net income was attributable to lower
revenue and gross margin contributions from Oceaneering's Subsea Products and
Subsea Projects business segments and a higher level of Unallocated Expenses.
All Oceaneering business segments continued to contribute profit margins,
despite a challenging market environment for oilfield services and products in
general.

      John Huff, Chairman and Chief Executive Officer, stated, "Results for the
quarter were encouraging and within our earnings guidance range. Revenues from
each of our six business segments were higher in the second quarter than the
first quarter.

      "When compared to the first quarter of this year, gross margin from our
Remotely Operated Vehicle operations increased on the strength of improved fleet
utilization to 72% from 64%. Geographically most of the profit improvement came
from our Eastern Region, particularly in Norway and West Africa, as anticipated.
Inspection & NDT gross margin increased due to higher service sales,
particularly in Europe, and an improvement in gross margin percentage derived
from the contribution of operations acquired in the first quarter.

      "Subsea Products gross margin improved on higher sales and an improvement
in gross margin percentage from both Multiflex umbilicals and Oceaneering
Intervention Engineering specialty subsea products. Subsea Products gross margin
was positively impacted by $1.3 million due to the successful completion of a
project at a lower cost than previously estimated. Backlog dropped to $26
million, down from $31 million at the end of the first quarter. Our relatively
low level of backlog continues to be attributable to depressed umbilical orders.
Certain orders have been delayed and we expect our backlog to be higher by the
end of this year. We are continuing our efforts to locate a suitable facility to
expand our U.S. umbilical plant manufacturing capacity. Profit contributions
from our U.S. and Brazilian steel tube capabilities are expected by the third
quarter of 2004.

      "Gross margin from our Subsea Projects segment declined due to a very
competitive market environment in the Gulf of Mexico for diving and
vessel-related subsea installation, repair and maintenance services. Unallocated
Expenses increased due to higher restricted stock expenses associated with our
long-term and deferred compensation plans. Gross margin contributions from our
Mobile Offshore Production System and Advanced Technologies segments were
comparable to the first quarter.

      "During the second quarter, we continued to have strong cash flow provided
by operating activities. Our capital expenditures, including acquisitions, were
$26.3 million. Our cash balance at quarter's end was $26.6 million and recently
we completed the arrangement of a new $100 million credit facility. We remain
committed to use our financial strength to make accretive investments, which
will expand and augment our existing operations, as well as to continue share
repurchases as conditions warrant.

      "Our current EPS outlook is approximately $1.40 for 2003. This reflects a
lower anticipated profit contribution by our Subsea Products operations. We are
projecting earnings per share in the range of $0.35 to $0.40 for the third
quarter.

      "At this time, we estimate 2004 EPS in the range of $1.60 to $1.75. This
estimate is based on incremental earnings contributions from Subsea Products,
driven by increased subsea completion activity, and additional asset and
acquisition investments. We anticipate continuation of current market conditions
or similar demand trends for our other five business segments. Should a
substantive recovery in market demand, particularly for our niche ROV and Subsea
Projects, occur we will be able to improve on this estimate by utilizing our
excess capacity and operating leverage."
