Summary
An oxygen-decanting incident aboard a dive support vessel produced an explosion and flash fire, causing superficial burns and equipment damage. Investigation identified three equally likely possible causes without establishing a direct cause. Reported measures included replacement pipework and valves, a dedicated oxygen line, non-destructive testing, valve-opening signs and regular oxygen cleaning.
