Narrative
Crimson gulf was advised of an unknown source oil sheen near texas petroleum investing company's (tpic) production platform delta duck 3" which ties into crimson's delta north 10" pipeline (la-dn-2). The subsea tie in resides approximately with 8' of water depth and several feet of cover. Tpic placed booms to contain the spotted sheen. Tpic notified crimson at 0946 cst, national response center (nrc), and louisiana department of wildlife and fisheries. Approximately 1200 cst crimson engineering and operations put inshore diving contractors (couvillion group) and environmental cleanup companies (oil mop) on standby. At 1211 cst crimson engineering mobilized couvillion group to begin diving investigation. At 1212 cst the delta north system was disabled from the crimson control center as per request by crimson gulf operations. Crimson sent an emergency permit application to u.S. Fish and wildlife (site is located within delta national wildlife refuge). Notification were made to federal, state, and local agencies. Continuing on the 23rd, divers cleaned the sub-sea assembly bottom and flushed the inside of manifold of the sub-sea assembly. The divers closed the valves to isolate the assembly, pneumatically pressure tested the assembly, and checked for leaks. The air bubbles were noticed coming out of one of the subsea assembly flanges (4). New bolts, nuts and a gasket were installed and properly torqued to repair the leak. Furthermore, the assembly was again pneumatic tested to ensure leak was repaired. After the successful test, water displaced the air out of the assembly, valves were opened, and production came online. Personnel oversight remained on location to visually check the area for a sheen during commissioning and throughout production.
