The ship’s main engine is the heart of the ship; and it needs maintenance too for smooth operation. With all major loading and discharge schedules made in advance; any critical damage leads to a huge loss of money and time.With the main engine accounting, more than 30% of the total machinery cost in the engine room. It becomes more important to keep it in shape from a monetary point of view; rather than satisfying ISM, IMO, flag, and port state regulations. Onboard ship, it is one of the works of the duty engineer; to perform inspection and maintenance of the main engine.

But against our common belief to overhaul complete unit or engine at a time; main engine parts and working parameters of different units are replaced and inspected based on their running time. They can be from daily inspection to the one needed after 8000 hours of operation.Before we proceed and look into these inspection, checks, and maintenance work. I would like you to revise the basic concept of an engine like the key parts of the marine diesel engine and its function.

  • Daily Checks And Inspection Carried On Ships Main Engine
  • Checks Carried Out On Engine After 250 Hrs Of Operation
  • Checks & Inspection Carried Out After 1000 Hrs Of Operation
  • Checks Done After 2000 Hours Of Ships Engine Operation
  • Maintenance And Overhaul At 4000 Hours Of Operation
  • Maintenance Done At 8000 Hours of Ships Main Engine Operation
