Radical derating of the 2-stroke engine is an innovation from Wärtsilä. We call this Wärtsilä Fit4Power.
Our experienced service teams optimize the engine power by significantly reducing the engine bore size. Improving engine efficiency by up to 15% or more. Extending an average ship’s CII compliance by 3-5 years. Offering breathing space until uncertainties in fuel availability and cost resolve.
When it is time to convert, the engine efficiency carries over. Making new fuels more economic. All of which makes this the ideal first step in your decarbonization journey.
