MAIB report reveals safety concerns in Greenock tug sinking
The Marine Accident Investigation Branch (MAIB) has released its findings on the tragic sinking of the tug Biter, which capsised off Greenock, Scotland on 24 February 2023, resulting in two deaths at sea.
The Biter, a twin-screw conventional tug, capsized while assisting the passenger vessel Hebridean Princess as it approached James Watt Dock.
The tug, attached to the stern of the larger vessel, was subjected to excessive force from the passenger ship’s speed, which reportedly overwhelmed the Biter’s safety equipment and led to the fatal incident.
“Tug Biter’s accident was another cruel lesson of how rapidly things can go dreadfully wrong,” said Andrew Moll OBE, Chief Inspector of Marine Accidents.
“In less than ten seconds, the tug capsized and two experienced seafarers lost their lives due to a breakdown in the systems that should have kept them safe.”
Critical safety concerns
MAIB’s report raised critical marine safety issues, particularly regarding the limited training of marine pilots in handling conventional tugs and highlighted incomplete communication between the pilot and tug crew.
The tug’s gob rope and open hatch, which compromised watertight integrity, were identified as factors that worsened the risks during the fatal tug sinking.
The MAIB has issued multiple safety recommendations to the tug’s owner, Clyde Marine Services, including enhanced safety protocols and mandatory training for tug masters.
Recommendations also urge Clydeport Operations and industry associations to improve training for pilots and crew to help prevent further deaths at sea.
