Casualty Event: Missing

Summary

 

Following departure from Odesa and completion of pilotage operations, three crew members were carrying out maintenance work at different locations on the main deck. At approximately 17:13 LT, one crew member was reported missing from his workstation at the starboard pilot station, where maintenance work had been underway. His equipment was found unattended and still operating. A full shipboard search was conducted, including repeated PA announcements and the sounding of the general alarm, but the missing crew member could not be located. A possible man overboard situation was declared, and the vessel immediately executed a Williamson Turn and broadcast a PAN-PAN message. Search and Rescue operations were coordinated with Odesa MRCC; however, despite extensive search efforts, the missing crew member was not found. The occurrence resulted in one crew member reported missing and presumed overboard.

 

Safety recommendations

SR 2026-247.1, to DENSA TANKERS LTD.:


Assess through onboard verification and feedback from seafarers, whether safety
learning from the DENSA DENIZ occurrence has been, or is being, effectively
implemented in comparable work near ships’ sides across the fleet.

Lessons learned

GAMA maritime safety investigation highlighted that:
• work near a ship’s side requires preventive barriers to remain effective throughout the task, including when a physical barrier must be opened or temporarily removed;
• risk identification and written procedures are important, but do not, by themselves, ensure a safe outcome;
• the organisation of work should provide an effective means of detecting when a person working in an exposed area may require assistance;
• emergency response measures can reduce the consequences of a man overboard occurrence, but their effectiveness depends on early detection;
• learning is strengthened when the experience of the vessel is discussed with seafarers, adapted to comparable work across the fleet and followed up to verify that the resulting measures are practical and effective;
• safety learning should include accidents, incidents and near misses, as well as successful recoveries and the practices that normally allow work to be completed safely.
