The UK Department for Transport Marine Accident Investigation Branch
(MAIB) has released its report of the investigation into an accident that caused major injury to an engineer officer on board the cruise ship Royal Princess in the Dover TSS on August 4, 2001. The officer was injured when crushed by a power-operated watertight door.
Investigation revealed that the written instructions for operating watertight doors were extremely complicated and that the crew regularly
deviated therefrom. The MAIB recommended that the operator simplify the written instructions and consider redesigning the watertight door
