Designed with a 9-cylinder configuration and a bore of 380 mm paired with a stroke of 475 mm, the Wärtsilä 9LW38-GS-50Hz operates at a power output of 4320 kW. Its medium-speed design runs at 750 RPM on HFO or MDO fuel types, ensuring efficient and reliable performance in marine environments. Common maintenance issues include cold corrosion of cylinder liners due to sulfur content in the fuel, which can lead to piston ring sticking; wear on cylinder liners and piston rings from low residual alkalinity in cylinder oil; and the need for regular turbocharger overhaul cycles every 50,000 operating hours. Additionally, gradual erosion of exhaust valve seats and potential wear on shaft seals and main bearings are frequent concerns that require diligent inspection and servicing.
