Summary
Investigation of a gas release on the Marlin tension-leg platform after a suction-scrubber pipe nipple fractured through fatigue cracking. Gas detection prompted shutdown and muster, with no injuries or significant equipment damage. The report examines vibration and inadequate bridle support, and records planned management of change to add support.
