This marine power equipment belongs to the medium-speed diesel engine class. The Wärtsilä 6LW38-GS-50Hz is a legacy model with a power output of 2880 kW at 750 rpm, designed to operate on Heavy Fuel Oil (HFO) or Marine Diesel Oil (MDO). The engine features six cylinders with a bore of 380 mm and a stroke of 475 mm, and it operates in a 4-stroke configuration. It is part of the W38-GS family, with a mean effective pressure of 2.7 MPa and a mean piston speed of 9.5 m/s. Each cylinder can produce between 660 and 725 kW of power, and the engine's total piston displacement is 53.9 liters per cylinder. The engine is equipped with dual inlet and exhaust valves per cylinder, and it is optimized for marine applications, offering a genset output of 2736 kW and 3420 kVA at 50 Hz frequency. Common maintenance issues include cold corrosion of cylinder liners, cylinder liner wear and piston ring degradation, turbocharger overhaul cycles, exhaust valve seat recession, and shaft seal and main bearing wear. These issues are influenced by factors such as fuel sulfur content, cylinder oil alkalinity, and operational conditions.
