Crew members, engineers, and operators on board ships depend on reliable power generation systems to ensure smooth operations. The HiMSEN 6LH25/33-GS-50Hz is a robust six-cylinder, four-stroke engine designed for marine applications. With a power output of 1650 kW at 750 RPM and capable of operating on heavy fuel oil (HFO), marine diesel oil (MDO), low-sulphur fuel (LSFO), and marine gas oil (MGO), this engine provides versatile performance across different fuel types. Engineered for durability, it features a compression ratio of 17:1, with emissions compliant to IMO Tier II and III standards. Regular maintenance is crucial to prevent common issues such as fuel injection pump sticking due to sludge buildup and carbon deposits in the combustion chamber when using low-sulphur fuels. Proper monitoring and adherence to maintenance guidelines can significantly enhance the engine's performance and longevity.

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.
