On October 11, 1994 at about 0410, the DONA V, a Liberian flagged bulkcargo vessel, was forced to shut down her main diesel engine because ofmechanical failure. The vessel was completing an 18 day trip from Chinato Tacoma and was to load bulk grain. When the Captain stopped the engine,the DONA V was approximately 2880 yards north east of Foulweather Bluffin Admiralty inlet Washington, in the inbound traffic lane. The vessel thendrifted in a south easterly direction at approximately 0.5 knots acrossthe traffic lanes and anchored near Double Bluff. She was later towed withoutfurther incident into the harbour anchorage. The Office of Marine Safetydetermined that the probable cause of the main engine casualty was a holein the piston crown of #2 cylinder. It is likely that the piston crown hadnot been removed or cleaned for many years, allowing the accumulation ofsludge on the crownís cooling surfaces. The loss of lube oil pressurecaused the main engine to shut down to avoid further damage to the engine. During the investigation the Chief Engineer was asked to explain theprocedures used to inspect pistons and piston crowns.
