Marine engineers and operators rely on reliable and efficient power solutions to keep ships running smoothly and ensure safe and continuous operation. One such solution is the Wärtsilä 18VW31, a diesel engine that delivers a robust 5490 kW of power at 750 rpm. This engine is designed to run on Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), and Gas Oil (GO), making it versatile for various maritime applications. The 18VW31 features a V configuration with a bore of 310 mm and a stroke of 430 mm, providing a displacement of 17 liters per cylinder. It meets the IMO Tier II emission standard and is turbocharged with an intercooler to optimize performance. However, operators must be vigilant about common issues such as piston ring wear, cold corrosion in cylinder liners, cylinder liner glazing, turbocharger bearing wear, and fuel injection nozzle coking, which can affect the engine's longevity and efficiency. Regular maintenance checks and adherence to manufacturer guidelines are crucial to prevent these issues and ensure optimal performance.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
