During morning attendance of engine room, a water leak from the exhaust gas boiler was discovered. In order to get to port, the water circulation was shut off, and the instruction manual on “emergency dry running” was followed. When arriving at anchorage, the exhaust gas boiler overheated, and the crew found that a soot fire had occurred.
In early October DNV released a technical newsletter focusing on the immediate and consequential impact of oil contamination on auxiliary boilers. This kind of leakage in coil flanges or broken gaskets in plate heat exchangers frequently occurs. If the problem is not observed in time, the boiler could be completely destroyed due to overheating of the furnace because of reduced water flow and minimised heat transfer/cooling of the boiler tubes.
