Narrative
At 0930 hrs. The morning of june 30, 2013, a small 50 ft. X 300 ft. Barely discernible to silvery sheen (approx. 0.02 gals.) was observed passing through the bay marchand field by a helicopter pilot and a passenger. This field is located in the gulf of mexico, close to the shore of lafourche parish, louisiana. This sheen was called into the nrc 25 minutes after discovery, at 0955 hrs. And assigned nrc. No. 1052251. Upon investigation by a dive crew in the field, the crude oil was subsequently determined to be coming from a pinhole leak on an 8 in. Gathering line which departs from chevron's bay marchand t/hh platform and arrives at the chevron fourchon terminal onshore. This updated information was also reported to the nrc and assigned an updated nrc number 1052265. The intrastate pipeline (segment no. St-0076) was immediately shut-in and plans were developed to repair the pinhole leak with a plidco split-sleeve clamp. This repair was completed and leak tested on the evening of july 3, 2013, the pipeline was returned to service on the morning of july 7, 2013.
