Summary
Investigation of a gas release during valve removal on a production platform. Inadequate isolation allowed pipeline gas to escape through open-ended coalescer piping. The report identifies check-valve malfunction, rushed decisions, deficient procedures, poor communication and fatigue, and recommends lockout and tagout, stop-work processes and coordination of simultaneous operations.
