Summary
BSEE investigated a pipeline leak at Grand Isle 76-A releasing an estimated 8.35 barrels of hydrocarbons. The report examines inadequate high-pressure trip and safety-valve settings as possible contributing causes, unauthorised conversion to bulk oil service, spill reporting and monitoring, and diver-observed pressure testing of a split-sleeve repair.
