On a ship operating under the 720 RPM rated speed, equipped with a non-reversible four-stroke diesel engine designed for propulsion, you can find the MAN Energy Solutions 10L32/40. This engine is particularly suited for vessels that require robust power, such as cargo ships or bulk carriers, delivering 4500 kW of power through its ten cylinders with a bore and stroke of 320 mm and 400 mm respectively. The engine operates on heavy fuel oil (HFO), marine gas oil (MGO), or marine diesel oil (MDO). Regular maintenance focuses on cylinder liner wear, piston ring sticking, charge air cooler fouling, and turbocharger bearing issues to ensure optimal performance and longevity in marine environments.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
