Summary
A vessel’s deck stand guide roller pin failed during mooring and struck a heater, without injury. Investigation identified degradation, inadequate inspection and a complicated line arrangement that increased axial forces and overloaded structures. Lessons address suitable mooring arrangements, avoiding multiple turns, toolbox discussions and three-yearly roller dismantling and overhaul.
