Doosan Engine

Summary

The four-stroke genset engine drives the ship's power generation system. The largest ocean-going vessels will have at least three of these engines onboard to ensure a sufficient power supply for operating the ship and accommodating the crew. Our genset engine portfolio includes the L27/38, L21/31 and L16/24, which are new-concept designs for 21st century requirements. Our L32/40 and L23/30H are also very popular with shipyards and shipowners.

 

The L27/38, L21/31 and L16/24 models are compact, and their piping and parts are arrayed for easy maintenance and repair. These engines are also very economical to operate. These benefits have made them the product of choice on many of the latest containerships and LNG carriers.

 

The L32/40 and L23/30H are commonly found on LNG carriers, very-large crude oil carriers and other tanker types. They save money by running on the same heavy fuel oil (HFO) used to power the low-speed main propulsion engine. The expenses for their maintenance and repair are also among the lowest in the industry.

 

Doosan Engine can now build medium-speed gen-set engines in capacities ranging from 500kW to 4,500kW.
