Remarks: Amerada Hess bottom towed across Garden Banks 323 on December 30, 1998. Mariner attempted to commission the pipelines on February 23.

Remarks: A 6" Sleeping Turtle pipeline developed a leak near a side tap, which was close to a tie-in. A diver discovered a shrimp trawl over the side tap valve. Approximate pollution was 3.6 bbls. May 31, 1999 - Chevron U.S.A., Inc.
Remarks: A leak developed in a 10" low pressure line from GI 37 "Romero" to shore. Approximately 5 bbls of oil spilled from the pipeline in state waters. A clamp was installed over the leak area. A stand- up test was done at 240 psig for one hour and no leaks were detected. The line was put back in service the same day.
July 23, 1999 - Equilon Pipeline Company LLC (on Seashell Pipeline right-of-way)
Remarks: A jack-up barge was hired to set a quarters building on Platform A. While setting its legs on the seafloor, it is believed the barge set its legs on the Cougar pipeline and damaged it. August 4, 1999 - British Borneo Offshore, Inc.
Remarks: A hydraulic hose on an underwater pipeline system leaked. August 12, 1999 - Vastar Offshore, Inc.
Remarks: A departing pipeline developed a small leak south of Platform D. September 20, 1999 - Vastar Resources, Inc.
Remarks: The tugboat Ellen Bouchard was towing an empty Bouchard Transportation Company barge (Barge B #195). The first mate was at the helm of the tugboat when, due to 20-knot winds, the barge collided with the south end of a production platform. The barge rolled into the east side of the platform, damaging a barge bumper and a 3-inch condensate pipeline (MMS segment #9509). The pipeline was taken out of service and a pig was pushed through it with natural gas in order to displace the condensate.
