Narrative
Boemre (formerly mms), contacted by black elk energy, notified tgp of a leak offshore in vermillion block 116 that appeared to be in the vicinity of tgp facilities. Tgp mobilized personnel and began to isolate facilities around the leak location. Tgp's 509a-1500 line was found to be the source of the leak. Divers discovered that a 1" body bleed valve and nipple was broken in the nipple threads, possibly caused by outside force impact such as a shrimp net. It should be noted that black elk energy called the nrc about the leak and was assigned no. 978918, which tgp claimed upon contacting the nrc. Tgp was assigned a new nrc number of 978958. The leak was repaired by drilling out the damaged nipple and replacing with a 1-1/4" nippled and valve. The repaired facility was placed back into service.
