Crew members, engineers, and operators aboard ships depend on reliable power generation for maintaining operations. The Wärtsilä 7LW22-GS-60Hz model ensures consistent performance with its robust design and advanced technology. This engine operates at a steady 900 RPM and offers a powerful output of 980 kW, making it suitable for heavy fuel oil (HFO) and marine diesel oil (MDO). With four-stroke configurations and turbocharged features, the W22-GS family provides efficient operation under various load conditions. However, regular maintenance is crucial to prevent common issues like wear on cylinder liners, piston plunger seals during HFO conversion, and failure of connecting rod bearings. Careful inspection and timely replacement can significantly extend engine lifespan and reliability.

Free of charge — send us your request for Wärtsilä equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
