Summary
Investigation of a flash fire during well abandonment on Eugene Island Platform F. Gas and condensate travelled through shared pressure-relief piping to an unblinded flowline and ignited at a cutting torch, injuring a welder. Findings address a leaking wing valve, inadequate isolation and joint job safety analysis.
