The condensate drainage pots fitted to Nireas’ main air receivers were not fit for purpose as they were not capable of withstanding the internal pressures that were likely to accumulate in service.
In the past 25 years the ATSB and its predecessor have investigated 39 collisions between trading ships and smaller vessels on the Australian coast. These investigations have all concluded that there was a failure of the watchkeepers on board one or both vessels to keep a proper lookout and that there was an absence of early and appropriate action to avoid the collision.
ClassNK did not have in place a system which ensured that updated service advice from the engine manufacturer was being implemented on board ships with engines which its surveyors were routinely and regularly surveying.
The ship’s planned maintenance system did not include all of the main engine manufacturer’s maintenance requirements. Furthermore, the maintenance records did not include sufficient detail to confirm that the main engine was maintained in accordance with the manufacturer’s requirements.
The stevedoring company had not identified stevedore fatigue as a risk to the company or its operations and, as a result, had not implemented a system to manage fatigue. Consequently, its operations were exposed to a level of fatigue-related risk that had not been assessed and treated.
While the risk of aluminium ingot stacks toppling over had been identified by the stevedoring company as a result of past incidents, its procedure for loading aluminium products had not evolved to adequately address this risk. Furthermore, the implementation of basic precautions such as using ladders to climb between ingot tiers was not effectively monitored or enforced.
The aluminium ingot lifts in Newcastle, comprising multiple stacks of ingot packs strapped together, with an effective height to width ratio of 5:1 were inherently unstable. Furthermore, handling and stowage of ingot lifts involved the risk of a lift being disturbed and one or more of its packs falling or toppling because the lifting and other straps were not designed to restrain the packs as a single homogenous cargo unit and were prone to failure.
A risk assessment for mooring a ship at the inner moorings had never been undertaken. As a result, the risks associated with leaving a ship at the inner moorings overnight during the swell season were not properly identified and strategies to minimise those risks were not implemented.
While the pilot provided limited advice to masters of ships visiting Christmas Island, the port operator did not provide the master of ships intending to berth using the buoys in Flying Fish Cove with any written or verbal guidance regarding berthing and unberthing arrangements and emergency contingencies.
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 port operator had not implemented an effective planned inspection and maintenance program for the mooring system in Flying Fish Cove. Consequently, it had been 18 months since the underwater components of the cantilever line had been inspected.
Bowen Tug and Barge did not have an effective compliance auditing process in place to ensure that its employees were following the training they had received and the guidance contained in the safety management system documentation.
Compliance auditing on board British Beech had not identified that requirements of the job hazard analysis were not being followed by the crew during the storing operations.
Bowen Tug and Barge’s safety management system guidance for barge storing operations did not designate roles or responsibilities to specific individuals and a system for communicating with the ship’s crew was not discussed and established.
The lack of any record of incident reporting by Bowen Tug and Barge, and its employees, indicates an ineffective reporting culture within the company. Hence, the opportunity to learn from previous incidents was lost.
Bowen Tug and Barge had identified the need to spread the slings when lifting a stores container. However, there was no process in place to ensure that ships' crews were advised of this to ensure its safe return from the ship.
Adonis’s safety management system did not contain any procedure or guidance in regard to the use and correct setting of the tug’s towing hook quick release arrangements.
The location of the towing hook ‘locking’ pin on the upper part of the quick release lever meant that if the pin was not properly in its ‘unlocked’ slot, it could fall into the locking hole, thereby locking the release lever.
The requirement in Sea Swift’s Marine Execution Plan to let Adonis go after clearing the Clinton coal wharves was ambiguous and this led to the crews of Adonis and Wolli misinterpreting the requirement.
MSC Siena’s permit to work over the side and the associated procedure required that the ship not be underway when working over the side. However, this requirement could not be complied with when working over the side to rig a combination pilot ladder.
