Cal Dive International Update Following Hurricane Rita

HOUSTON, TX — Cal Dive International, Inc. (Nasdaq: CDIS) announced today an update following the passage of Hurricane Rita.

Marine Contracting

All marine personnel, assets and operating bases came safely through the storm with most vessels remaining on hire. All operational vessels are now back to work and the first three of the recently acquired Torch assets are expected to be deployed early in October.

Oil and Gas Production

All offshore activities were suspended as of Thursday, September 22, 2005, with all operations personnel safely evacuated. Net daily production of approximately 100 million cubic feet of natural gas equivalent (MMcfe) (down from pre-Hurricane Katrina volumes of 110 MMcfe/day) was shut in.

Energy Resource Technology (ERT), our oil and gas production subsidiary, conducted flyovers of its properties after the hurricane which indicated that one producing platform has been significantly damaged and two non-producing platforms have been lost. Several other producing platforms sustained damage that appears to be repairable within the short term. The repair cost, net of insurance proceeds, is expected to be less than $10 million.

ERT estimates that daily production will be brought back on line according to the following time line, subject to the availability of third party pipelines:

      By 9/30                       50 MMcfe

      By 10/15                     65 MMcfe

      By 10/31                     85 MMcfe

      By 12/31                     100 MMcfe

Production Facilities

A flyover of the Marco Polo platform indicated no significant damage and an announcement is expected soon from the operator, concerning the resumption of production.

Owen Kratz, Chairman and Chief Executive Officer, stated, “Hurricanes Katrina and Rita have added meaningfully to the already robust demand for Marine Contracting services, offsetting impact on our Oil and Gas Production and Production Facility businesses.

“Based on this situation, we reaffirm our previously released earnings guidance of $2.80 to $3.20/share for 2005 and currently believe earnings will come in near the high end of that range. We will further refine this estimate in our third quarter earnings release scheduled for November 1, 2005.”

Cal Dive International, Inc., headquartered in Houston, Texas, is an energy service company which provides alternate solutions to the oil and gas industry worldwide for marginal field development, alternative development plans, field life extension and abandonment, with service lines including marine diving services, robotics, well operations, facilities ownership and oil and gas production.
