MAIB report highlights safety failings, calling for stricter mooring procedures in Chile
The Marine Accident Investigation Branch (MAIB) has unveiled findings into the fatal accident in August 2021, involving the bulk carrier Mona Manx, leading to an investigation calling for stricter mooring procedures at Puerto Ventanas, Chile, following the death of the vessel’s second officer.
During the docking procedure, the officer was struck by a recoiling mooring line. The line had become trapped between the ship and a dock fender before snapping free as the vessel moved backwards under engine power.
The report identified several critical safety failings. The ship was using its engines to manoeuvre along the berth, which is a direct violation of port regulations. In addition, the crew hadn’t been correctly briefed on the manoeuvre, and standard safety protocols for mooring line hazards were inadequate.
The MAIB has issued recommendations to Puerto Ventanas and the Quinetero Port Authority, calling for comprehensive updates to safety protocols. These include clearer instructions about engine use while moored and better guidance on mooring line entrapment risks.
The investigation also found that international safety guidelines for merchant seafarers do not adequately address dangers of line entrapment or vertical recoil, suggesting broader implications for maritime safety standards.
