Investigation Reveals Causes Behind Argos Georgia Tragedy

According to a recent report from the Marine Accident Investigation Branch (MAIB), the tragic sinking of the fishing vessel Argos Georgia, which resulted in 13 fatalities last year, was primarily due to a malfunctioning shell door. The incident occurred on July 22, 2024, approximately 190 nautical miles east of Port Stanley in the Falkland Islands while the vessel was en route to fishing areas near South Georgia.

The St Helena-registered longline fishing boat capsized with 27 crew members aboard; while 14 were rescued during extensive search efforts, sadly, many lives were lost during both abandonment and rescue attempts.

The investigation revealed that at the time of sinking, a shell door located in the hauling compartment had been observed transitioning from a closed position to fully open via closed-circuit television footage. This failure allowed water to flood into critical areas of the ship. Furthermore, internal doors leading from this compartment were left open, exacerbating water ingress and causing an increasing list as more water accumulated.

Crew members faced challenges in closing the shell door once it opened and could not manage escalating flooding conditions that ultimately led to their vessel’s demise. Some crew tragically perished while attempting evacuation or while awaiting rescue on liferafts.

In light of this disaster, MAIB issued a safety bulletin in October 2024 urging all fishing vessel operators with similar designs to evaluate potential risks associated with shell doors and implement measures for risk mitigation against flooding between compartments.

A follow-up technical assessment completed by July 2025 identified significant stress levels on components such as the shell door drive shaft and coupling during operation. This condition raised concerns about possible failures that could allow gravity alone to keep these doors ajar despite normal closing mechanisms being disabled.

The MAIB has called for operators and designers involved with these types of vessels to reassess their operating mechanisms’ design and make necessary modifications. Any updates should be communicated across fleets utilizing comparable designs for enhanced safety standards within maritime operations.

The comprehensive investigation is now concluded; preparations are underway for stakeholder consultations regarding a draft report detailing findings and recommendations moving forward.
