Crew members and engineers on board ships depend critically on reliable maritime equipment to ensure safe operations. Wärtsilä's 14VW46 Methanol engine, with a power output of 9100 kW at 600 rpm in a V-configuration, plays a key role in this reliability. This dual-fuel engine operates on methanol and marine diesel oil (MDO), offering flexibility and efficiency. With two-stage turbocharging and common rail direct injection, it ensures robust performance while reducing emissions. Operators must be aware of potential issues such as poor combustion at low loads leading to carbon deposits and cylinder liner wear due to inadequate lubrication. Regular inspections and maintenance are crucial to prevent these common failures, ensuring smooth sailing for vessels worldwide.

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.
