Narrative
On 8/17/22 at approximately 07:43, while re-pressurizing line segment 3394, energy transfer was notified by a producer that a sheen was spotted in the vicinity of stingray 30-inch line segment 3394 in the wc550 block. Steps were immediately taken to shut in and isolate line. A call was placed to the nrc by the producer. Et confirmed the sheen with an overflight. Et outsourced a depressurization spread and dive company to investigate the leak site.
