HC Rubina’s electronic planned maintenance system did not contain any instructions to ensure that the shaft alternator flexible coupling was maintained in accordance with the manufacturer’s requirements.
Safety action taken by IMM Shipping to improve the planned maintenance of critical items of equipment and machinery reduces the likelihood of the failure of such equipment on ships that it manages.
The Australian Transport Safety Bureau recommends that IMM Shipping takes action to address the lack of instructions in the planned maintenance systems of its managed ships, to ensure that ship equipment is maintained in accordance with manufacturers' requirements.
Safety action taken by IMM Shipping included obtaining the detailed maintenance history of the ship's critical equipment, such as main and auxiliary engines and associated propulsion components, from their manufacturers. The company's technical management then identified the maintenance and overhaul requirements for such equipment and machinery in the planned maintenance system. The same equipment on an identical ship in the company's fleet was also inspected and precautionary measures, including replacing the shaft alternator flexible coupling, were taken.
