The port operator was aware that the type of locking pin arrangement on the cantilever line joining shackle was not effective in preventing the shackle’s pin from working its way free. However, the operator had not implemented a program of replacing the shackles in the entire mooring system in Flying Fish Cove with new shackles that had a more robust locking pin arrangement.
The replacement of the underwater mooring components will result in the replacement of all shackles with shackles with a more robust locking arrangement.
The port operator is in the process of replacing the mooring equipment including the anchors, dumpers, chains and shackles. These works are scheduled to be completed in May 2013.
The ATSB is satisfied that the action taken adequately addresses this safety issue.
