What our service work and the manufacturer documentation say about keeping this model running.
Review operating trends for lubricating-oil pressure, coolant temperature, exhaust temperatures, load balance, crankcase condition and abnormal vibration or noise. Inspect filters, coolers, fuel equipment, valve gear, turbocharging equipment, mounts, flexible connections and safety shutdown devices in accordance with the installed configuration. Check for fuel, oil, coolant and exhaust leakage and verify that protective alarms and shutdowns are functional. A surveyor will normally look for evidence of disciplined maintenance, clean machinery spaces, leak control, intact guards and reliable safety functions. Use the engine serial number and manufacturer documentation for all exact wear limits, adjustment values and overhaul criteria.
Useful onboard spares typically include fuel-system service items, lubricating-oil and fuel filters, cooling-system seals, belts where fitted, valve-train consumables, injector-related service parts, sensors and common gaskets or O-rings. Critical spares should be selected against the exact engine serial number, installed emissions package and vessel redundancy; refer to the manufacturer parts documentation before ordering.
