Common failures & inspection points

Fuel valve carbon deposits / fuel system blockages in low-load multi-fuel operation

Inspect fuel valve nozzle spray pattern during top-overhaul; monitor differential pressure across fuel filter; verify fuel heating system temperature compliance

Piston crown thermal cracking and top-land spalling under extreme load or fuel quality variations

Measure piston crown surface condition using borescope; check for micro-cracks in top land; examine combustion bowl geometry; compare cylinder-to-cylinder pressure readings

Cylinder liner scuffing/scoring in dust-contaminated conditions or with inadequate air filtration

Perform liner diameter measurement service at each overhaul; document wear rate trending; inspect piston rings for abnormal wear patterns; check air inlet filter condition

Turbocharger surge and cavitation erosion in unsteady loading (e.g., dynamic positioning vessels)

Monitor turbocharger bearing temperatures during mode transitions (gas-to-diesel); inspect turbocharger for cavitation pitting on impeller; verify surge line compliance in operational envelope

Fuel gas supply system pressure regulation instability (iGPR unit hysteresis) under rapid load changes

Perform fuel gas system pressure step-response test during commissioning; verify regulator response time <500ms per specification; conduct annual gas line tightness test with ultrasonic detection
