Marine engine and technology developer WinGD has updated its X72DF dual-fuel engine platform and launched four new versions.

WinGD said the new versions are designed for providing ship design flexibility and helping owners reduce installed power and emissions.

“Our most successful engine model is now available in four configurations,” said WinGD global sales director Volkmar Galke, “these options reflect the varied demands on shipowners to design vessels more efficiently, reduce installed power and cut emissions dramatically. Whatever route shipowners choose to meet these demands, there is now an X72DF that will work for them.”

The base version, X72DF-1.1, incorporates the company’s new engine control architecture, WinGD Integrated Control Electronics (WiCE). Several design improvements, focused on enhancing reliability while simplifying production and installation, were made along with the addition of a modular scavenging concept to improve control over combustion and emissions.

For five and six-cylinder engines, further optimisation is available to improve efficiency at lower power outputs. The X72DF-1.2 features a selected power/speed range with a lower specific fuel consumption. This configuration designed specifically for ships like the LNG carriers will be attractive to owners and shipyards seeking to limit installed power in line with the IMO’s energy efficient design indexes for newbuilds and existing vessels.

The new versions are both available as X-DF2.0 upgrades featuring iCER (intelligent control by exhaust recycling) technology. Released in June last year, iCER reduces methane emissions by up to 50% compared with X-DF1.0 engines. The X72DF-2.1 and 2.2 have been specifically tailored for all LNG fueled vessels.

With improved overall GHG emissions, reduced methane slip and lower gas consumption, the X72DF-2.0s are the most competitive solutions in terms of opex and overall emissions for LNG carriers, capesize bulkers, suezmax tankers and 3,000 - 8,000 teu containerships. 

The first delivery of the new versions is scheduled for April 2022, with delivery of the first iCER-equipped version targeted in the third quarter of that year.

According to WinGD, X72DF is the best-selling engine in WinGD’s portfolio and accounted for every low-speed engine ordered for a newbuild LNG carrier in 2020.
