Summary
Investigates a brief fire during torch cutting for well decommissioning on Ship Shoal 177 A. Slag ignited gas leaking through an adjacent well’s surface safety valve diaphragm. Findings identify failure to shut in that well, conflicting work documents and poor communication. The fire was extinguished immediately, with no harm or damage.
