The Australian Transport Safety Bureau (ATSB) has released an interim report detailing the events surrounding a bulk carrier’s loss of propulsion while departing Port Hedland in February 2025. The report provides insight into how the incident unfolded, the coordinated response by pilots and tug masters, and the ongoing investigation into communication lapses that delayed the reporting of the event.
Loss of Propulsion and Emergency Response
According to the ATSB’s findings, the fully laden vessel departed Port Hedland in the early afternoon under the guidance of two harbour pilots, assisted by four tugs. About an hour into its transit through the narrow channel, the ship’s main engine suddenly shut down while travelling at approximately 8.3 knots.
The pilots immediately notified the tug masters and vessel traffic service, requesting additional tugs to help maintain the vessel’s position within the channel. Over the next thirty minutes, seven tugs collectively worked to prevent the ship from grounding, keeping it safely within the confines of the passage.
Subsequent engineering checks revealed that the shutdown had been caused by a faulty switch monitoring the main engine’s lubricating oil pressure. Once the issue was rectified, the trip lockout system was reset, and the engine restarted. Within 35 minutes, the ship regained propulsion and safely exited the channel toward open waters.
Investigation Progress and Reporting Issues
During the vessel’s onward voyage, inspections of ballast tanks and an underwater survey confirmed that there was no physical damage to the hull. However, the ATSB noted delays in the reporting process. The incident was not promptly communicated to the ATSB, which only became aware of it months later through media coverage.
The investigation will continue to examine the event sequence, data logs, vessel tracking, and communication procedures. A particular focus will be placed on understanding why the initial report did not reach authorities in a timely manner, despite proper submissions being made to other maritime agencies.
The ATSB emphasized that incidents like this highlight the high operational risks associated with Port Hedland’s narrow and busy channel. A propulsion failure can potentially block the passage and affect multiple vessels simultaneously. The final report, once completed, will provide further analysis and recommendations aimed at strengthening safety and communication protocols for vessels navigating this critical trade route.
