MAIB calls for global fire safety overhaul after Finnmaster cargo vessel blaze

Investigations into a 2021 fire in the auxiliary engine room of Finland-registered roll on/roll off-cargo vessel Finnmaster have sparked calls for international changes to maritime fire safety standards.

The incident occurred at 20:13hr on 19 September 2021, shortly after the Finnmaster departed Hull in the UK. A mechanical failure led to fuel leaking from a flexible hose – installed during an unapproved modification – onto a hot surface, igniting a fire that knocked out the vessel's power. Tugboats assisted in safely re-berthing the ship. No injuries were reported, but the auxiliary engine room sustained significant damage.

Investigators at the UK Marine Accident Investigation Branch (MAIB) found multiple safety system failures. The emergency generator's circuit breaker malfunctioned, leaving critical systems offline. The fixed CO₂ fire-extinguishing system also failed to fully operate due to defects, hampering the crew's response.

In the wake of the incident, 12 safety recommendations have been issued to the Finnish administration (TRAFICOM). A key proposal urges TRAFICOM to advocate for amendments to International Maritime Organization regulations, specifically around testing emergency power sources , radio communication equipment, and fixed fire-extinguishing systems.

Finnlines Plc, the vessel's owner, has been advised to strengthen crew training and defect reporting procedures. Classification society RINA has also been urged to review its fire protection maintenance protocols and improve guidance for surveyors and chief engineers.

The Finnmaster fire highlights the urgent need for robust fire safety systems and international collaboration to prevent similar incidents at sea, the MAIB report states.
