The planned maintenance system on board British Sapphire did not detail a procedure for a recommissioning test following maintenance on the fast rescue boat davit. As a result, any recommissioning test that was done after on board maintenance had not identified the issue with the wave compensator safety interlock prior to the incident.
Action taken by BP
The ATSB has been advised that a requirement to complete a boat launch has been included in all invasive lifeboat and rescue boat davit maintenance job descriptions as follows. Complete boat launch procedure as soon as possible post this maintenance to confirm satisfactory operation of all controls, indicators, components, limit switches, brakes and protection devices.
The ATSB is satisfied that the action taken by BP Shipping adequately addresses the safety issue
