Protection against Crankcase Explosions


A recent incident involving a crankcase explosion on a large slow speed diesel engine caused injury to one of the engineers and extensive damage to the engine and machinery space. In the event, the lapsed time between the oil mist detection alarm/request for slow down and the crankcase explosion was just a few minutes and therefore the following control system feature, if not already fitted, is now recommended: To expedite the slowdown of the engine in the event of a high concentration of oil mist in the crankcase the slowdown should be effected automatically instead of manually with only a few seconds delay and should override the normal load down curve.

In the event that a shaft generator is fitted the automatic slow down should immediately bring the main engine rpm down to the minimum acceptable for the shaft generator. Once the standby auxiliary generator has automatically started and connected to the switchboard the slow down should further reduce the main engine rpm to the pre-set slow down value. If over-ride facilities are provided for the oil mist slowdown and the low lubricating oil pressure shutdown then these are to be independent. A single over-ride switch would not be permitted. At this time the opportunity should also be taken to remind ships' staff that during crankcase inspections, (a maximum interval between inspections is specified by the engine builders), special attention must always be given to the checks of the oil collection/drain trunk for any particles of bearing material. Should any such particles be found the damaged bearing must be identified, examined and where necessary replaced with the ship’s spares.
