May 30, 2013 by Leave a Comment
This incident is referring to a vessel which had an exhaust gas heated Thermal Oil installation. The thermal oil circulating pump stopped and the stand-by pump did not start. No alarm indicating abnormal condition was given. The thermal oil system temperature and pressure increased until the safety valve directed the oil into the compensating (expansion) tank. The expansion tank overflowed (again no alarm was given) through its air vent head. The air vent head was mounted inside the funnel, close to the exhaust pipes. An explosion was heard from the funnel followed by a fire.

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.
