X62DF

For LNG carriers, Aframax tankers, Panamax and Kamsarmax bulkers as well as feeder container vessels

WinGD low-pressure dual-fuel technology has been developed to respond to the market requirements of providing a propulsion solution capable to run efficiently, effectively and safely on gas, on top of conventional heavy fuel oil or diesel oil. The technology is based on the low pressure gas system concept. This system has a competitive initial investment and fulfils Tier III emission requirements without any external exhaust gas after treatment system. In brief, the technology allows a merchant two-stroke engine to simply, safely and reliably run on gas.

Available from 5 to 8 cylinders configuration, covering a power range from 7,700 to 19,080kW at 80 to 103rpm.
