The ATSB is investigating a loss of propulsion on the livestock carrier Al Messilah at Fremantle Inner Harbour, Western Australia.
On 4 March 2025, Al Messilah was manoeuvring to its assigned berth with a pilot onboard, assisted by two tugs. During a critical phase of pilotage in the harbour channel and past the abort point, Al Messilah experienced an engine malfunction. The tugs manoeuvred the vessel to its berth.
As part of its investigation, the ATSB has examined the reason for the engine failure, and the related safety issues. The investigation has included interviewing the directly involved crew, the master and pilot, analysing recorded data and weather and examining relevant records and documents.
In the course of the investigation, the ATSB has identified potential] limitations in risk controls relevant to the occurrence that are considered likely to have contributed to the occurrence. Examination of these factors represent a significant increase in the scope of this investigation, and it has been upgraded from Short to Defined as a result (the ATSB's different levels of investigation are detailed here).
The final report has been drafted and is undergoing internal review to ensure the report adequately and accurately reflects the evidence collected, analysis, and agreed findings.
Should a critical safety issue be identified at any time during the investigation, the ATSB will immediately notify the operators of the ship and the port, and other relevant parties so that appropriate and timely safety action can be taken.
The final report will be published at the conclusion of the investigation.
