MMS 99-0053		 Activity: Development
Lease: G02177 Amount(bbl): 8,212 - Crude Oil
Area: South Pass Operation: Pipeline
Block: 38 Cause: Hurricane, Mudslide, Human Error
Segment: 5625 Water Depth: 110’

Remarks: The damage to the pipeline occurred as a result of a natural hazard, specifically, a mudslide that was precipitated by Hurricane Georges in the latter part of September 1998. The pipeline was found completely parted 20 feet below the mudline. Deviations from established other-than-normal startup operating procedures contributed to the failure to identify the pipeline leak promptly. OCS Report 99-0053
