Summary
An offshore production platform investigation examines a gas release following compressor removal. Rising pressure dislodged a plumber’s plug from shared suction piping, triggering gas detection, platform shut-in and muster. Findings identify unsuitable isolation, inadequate JSA hazard recognition and insufficient oversight of the operator’s lockout and tagout policy.
