Engine Worn Out by Catalytic Fines

DNV has over the last years seen an increase in engine damage due to catalytic fines, even though the bunkered fuel has been in accordance with ISO 8217 marine fuel specification and fuel treatment is standard procedure and implemented for all vessels. Damage (incident occurred in 2010), that can be traced back to catalytic fines occurred after only 100 running hours, making the engine totally inoperable. All pistons and liners were totally destroyed and had to be changed.

MV Selendang Ayu Grounding – Investigation Report

On December 8, 2004 the M/V Selendang Ayu, a Malaysian bulk carrier, ran aground off the coast of Unalaska Island in western Alaska’s Aleutian Islands. The grounding caused the ship to break in half  and resulted in an oil spill of approximately 336,000 gallons of fuel oil and diesel fuel that led to an environmental cleanup lasting until June 2006. During the rescue operations a coast guard helicopter crashed and six of the vessel’s crew died just moments after being rescued, while the last persons onboard the ship, the master and a rescuer, watched a few minutes later the ship breaking in half.

Main Engine Damage Due to Fuel Contamination from Dry Cargo

When a bulk carrier was at sea, high exhaust gas temperatures were noted and several piston rings were found broken after investigation. The rings were renewed and engine restarted. After some hours of running the main engine it malfunctioned once again and more broken rings weer found. The broken rings were again replaced, but then the engine failed to start and the vessel had to be towed to port. A considerable number of piston rings were broken. Excessive wear of liners and piston crown grooves were also found. The fuel oil used was suspected to be a probable cause, although the quality of it was not found abnormal according to the test report.
