X72DF-1.1

X72DF-1.1

Designed for LNG carriers, Suezmax tankers, Panamax and Sub-Panamax containers and Capesize bulkers

WinGD low-pressure dual-fuel technology has been developed to provide a flexible propulsion solution able to run efficiently, reliably and safely with both gas or liquid fuels. 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. X-DF technology offers future-fuel flexibility with low emissions for cleaner air today.
