Winterthur Gas and Diesel, the Swiss-based marine engine and technology developer, said it had updated the X72DF dual-fuel power package favoured by many LNG carrier owners.

The company, also known as WinGD, said it now had four versions of the engine to provide ship design flexibility while helping owners reduce installed power and emissions.

“The 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,” said WinGD.

“It is also applicable on Suezmax tankers, Panamax and sub-Panamax containers and Capesize bulk carriers,” added the company.

Alongside baseline design improvements to the engine, an option is now available to optimise lower power output in five and six-cylinder configurations.

These new versions are also available with enhanced methane slip-reducing X-DF 2.0 technology.

“Our most successful engine model is now available in four configurations,” said WinGD executive Volkmar Galke.

“These options reflect the varied demands on shipowners to design vessels more efficiently, reduce installed power and cut emissions dramatically,” added Galke.

“Whatever route shipowners choose to meet these demands, there is now an X72DF that will work for them,” he declared.

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,” said WinGD.

“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,” stated the Swiss company.
