A high-power marine diesel engine, the 12V3512B by Caterpillar, is designed for demanding applications. This V-type, 12-cylinder engine operates on medium-speed diesel oil (MDO) and features a robust 4-stroke configuration with a bore of 320 mm and a stroke of 480 mm. It delivers 1560 kW at 1800 RPM, making it suitable for both propulsion and generator set applications. Known for its reliability and efficiency, this engine was introduced in 1994 and has maintained a strong presence in the market with over 1600 units produced since then. Common maintenance concerns include fuel quality management, especially when running on heavy fuel oil (HFO), as well as monitoring crankshaft bearing conditions due to potential wear issues.

Free of charge — we forward your request to qualified suppliers for Caterpillar equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs 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.
