The retrofitting of engines can significantly improve the environmental impact of ships. While retrofitting a two-stroke engine can be a complex process, retrofitting a four-stroke engine is generally feasible. However, it’s important to note that retrofitting an engine that is more than 60 or 70 years old may not be practical.
For modern engines built around or before the year 2000, retrofitting with systems such as Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) can be an effective way to make the ship a cleaner vessel and reduce its effects on the environment. The type of system installed can be tailored to the client’s specific needs.
It’s important to note that retrofitting an engine with emission reduction systems does not necessarily mean the ship will meet certification requirements. However, it will result in a significant reduction in harmful emissions and make a positive impact on the environment.
