Summary
BSEE investigates the discharge of 80 barrels of synthetic oil-based mud from Diamond Ocean Blackhawk during Coriolis meter flushing. Shakers remained off when the mixing pump started, allowing mud to reach an open overboard discharge line. The report identifies procedural failure and inadequate hazard analysis, with prior JSA review unconfirmed.
