If there is one standout cause for failures of main and auxiliary engines, it is through inadequate monitoring and maintenance of the condition of lubricating oil – literally the life-blood of any engine. The American P&I Club has issued a new case study taking into account best practices in the prevention of shipboard machinery failures.
The case study incident:
The medium speed main engine of a bulk carrier suffered a turbocharger failure whilst on transatlantic passage to New York. The engine had then labored for several days with a non-functional turbocharger creating very poor combustion and black exhaust smoke. Whilst in port and undergoing turbocharger repairs the attending surveyor recommended that lubricating oil samples be taken from the main engine for analysis. It wasn’t done, and several days later during another loaded passage, the main bearings and then the crankshaft failed leading to towage, large general average costs and extensive disputes over seaworthiness.
