Narrative
Notified by operator of a large sheen on the water. Operators currently investigating the cause of the sheen. East division. Call recieved from tim brazer: updated flyover was conducted at 08:00 cdt, and the spill volume is now at 147 gallons, direction current dimensions: 36, 960 feet (7 miles) length, 5280 feet (1 mile) wide, 40% coverage, colors: 10% barely visible, 80% silvery, 10% slightly colored, moving toward the northwest. Update: caller confirmed source is from energy xxi and coming from 10 inch pipeline, currently isolated, sheen has dissipated, located 1.5 miles south of south pass 77a and south pass 57a. Pipeline segment# 15008. Updated nrc# 119-3261. Divers located separated pipe, which is believed to be caused by a mudslide due to the aftermath of hurricane nate. Pipeline was found approximately 250 feet south of original known location. For part a, question #9: the volume calculation for how much commodity was released is based off of the estimated square footage of the sheen multiplied by the estimated coverage determined by the appearance of the sheen. For part e, question #1: platform was brought back online at roughly 7 pm on 10/13. Pump was cycled up to 100 psig from 10/13 at 7:30 pm until shut-in at 6:30 am on 10/14 when sheen was spotted. Max pressure was 100 psig. Scada is not installed on this pipeline section, therefore no scada indications to report. For part g2: the pipeline was found to be buried 10-20 feet below the mud line eliminating the initial thought of an anchor drag. This pipeline is in a mudslide area and found to be approximately 250 ft south of its original location. In october of 2017 10" oil pipeline psn-15008 parted in a mudslide area between platform sp-77a and sp-55a. The scope of work entailed survey boat pipeline locating, and diver recon of the subsurface area, excavation of the pipeline at leak source with approximately 15' mud cover over the pipeline. Deep ditch excavation was required with a 3:1 safety factor on ditch wall utilizing diver's handjet, airlift, and toyo-pump. The diving contractor located leak path and installed a repair spool piece to repair the severed pipeline. Project duration was approximately 5 weeks.
