Summary
An offshore sour-gas piping rupture released natural gas containing hydrogen sulphide without injury. Earlier ultrasonic testing had identified serious corrosion near the failed elbow, but no corrective action followed. The alert recommends detector testing and breathing-equipment familiarity during drills, and asks operators to consider periodic ultrasonic inspection, prompt results review and predetermined wall-thickness limits.
