At about 1745 on 27 October 2008, during cargo discharge operations whilst alongside in Port Kembla, New South Wales, the chief mate of Great Majesty remotely opened two ballast valves adjacent to the number two water ballast pump (No. 2 WB P/P) to gravitate2 seawater into the number one water ballast tank (No. 1 WBTK).
About 10 minutes later, the engine room bilge alarm sounded and
the duty motorman found seawater flooding into the space through
the open casing of No. 2 WB P/P. Repair work had been started on
No. 2 WB P/P but the suction line had not been blanked off.
The inflow of water was stopped after the alarm was raised. About 390 m3 of seawater had entered the engine room and a total of 22 electric motors located on the lower levels of the engine room were damaged by the water ingress.
The investigation found that the ballast operation procedure did not provide sufficient guidance to the crew. The investigation also found that the work permit system onboard had not been effectively implemented. Consequently, most maintenance and repair work being carried out by the ship's crew was without a work permit.
