A UK crew has been blamed for their cargoship dragging anchor and hitting two other ships earlier this year.
The UK Marine Accident Investigation Branch (MAIB) said the 4,100-dwt Celtic Spirit (built 1996), operated by Charles M Willie, moved in heavy weather on the River Humber on 1 March.
It subsequently collided with the 700-dwt research and survey vessel Atlantic Explorer (built 1991) and its own 4,100-dwt sistership Celtic Warrior (built 1996), which were also at anchor.
