Common failures & inspection points
Exhaust valve fouling due to sodium/vanadium deposits (Na2SO4, CaSO4, V2O5) with heavy fuel oil containing high sulphur content (up to 5%); below dew point conden
Turbocharger fouling due to coal and ash particles in exhaust gas during low-load operation, BMEP decline and combustion deterioration
Piston ring leakage and fuel dilution (>2-3%) due to wear on cylinder running surface/piston rings, increased blowby and oil contamination
Cylinder liner wear due to corrosive combustion with sulphurous fuel oil; inspection criterion: wear according to height of sliding surface, max. permissible
Main bearing wear due to oil contamination; weekly inspection for water ingress (<2% permissible) and 3-month analysis for wear metals (Fe, Cu) required
