Marine Generator Sets

Industry-leading technology allows Caterpillar to create the most reliable commercial engines for a variety of applications. From tugs and container vessels to yachts and sport fishers, Cat and MaK engines have demonstrated their efficiency countless times. With remarkable reliability and durability, these engines will exceed your expectations for decades.

VM 32 C

The VM 32 C was introduced in 2000 in 12- and 16-cylinder versions. The generator set is designed to meet not only the demands of the marine market but also those of the stationary electric power generation and oil & gas industry. The modular construction of the engine, the integration of various functions into a single component, the robust design and the utilization of proven in-line engine components form the basis for a wide availability range of this engine. Reliable heavy fuel oil operation, low fuel and lubricating oil consumption together with easy maintenance and long maintenance intervals mean an outstanding economical operation.
