The Swedish Club has described an incident of machinery failure onboard due to lubrication contamination in their system. An investigation showed that the engine had been operated on a high thermal load for a long time and the turbocharger’s efficiency had been affected by fouling, while the lubrication oil had been contaminated for some time.
The vessel concerned was at anchor, in ballast, awaiting further instructions. The weather deteriorated after seven days and the vessel’s anchor dragged. The anchor was heaved up and the vessel started to slow steam in the area. After about 24 hours, the differential pressure alarm of the main engine duplex lubrication oil filter sounded in the ECR. The crew found aluminium and other Continue reading “Machinery failure caused by lubrication contamination case study”
