The 12-cylinder V-type four-stroke engine design ensures high efficiency and robust performance for maritime applications. Caterpillar's MaK series M32-GS family, specifically the 12VM32-GS-50Hz model, operates with a bore of 320 mm and stroke of up to 480 mm, delivering 5280 kW at 750 RPM for propulsion or generator sets. The engine is designed to handle heavy fuel oil (HFO) and marine diesel oil (MDO), with some 75% of the fleet running on HFO due to its efficiency and lower cost. Key features include a turbocharged system with low wear rates, making it reliable yet requiring careful management of fuel quality and lube conditions. Regular inspections are advised, particularly for crankshaft bearing condition monitoring and anti-corrosion measures in the cooling system.

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.
