WinGD, a joint venture of Wärtsilä and China State Shipbuilding (CSSC), has secured a contract to deliver a Wärtsilä X92 low-speed engine for French shipowner CMA CGM's 'mega-class' container vessel.
Planned to be built by Hanjin Heavy Industries & Construction (HHIC) in Philippines, the vessel is said to be the largest-of-its-kind for the French company. It will be designed to accommodate more than 20,000 TEU cargo.
The largest of Wärtsilä's Generation X engine series, the X92 engine, has a power range of between 24,420kW and 73,560kW at 70rpm to 80rpm.
The two-stroke engine incorporates common rail technology, which improves its fuel efficiency.
Wärtsilä said that the low revolutions of the engine will drive ship propulsion efficiency for large and ultra-large vessels.
WinGD CEO Martin Wernli said: "The Wärtsilä X92 engine has been designed to provide exceptional reliability, the lowest operating costs and minimal exhaust emissions, all of which are essential in today's operating environment.
"As container vessels are getting ever bigger in order to achieve economies of scale, it is essential that the engines and propulsion equipment are developed accordingly so as to achieve the efficiencies needed."
In February, the X92 engine has completed its design validation and factory acceptance tests, and demonstrated its compliance with classification societies' requirements.
The engine is planned to undergo type approval test and sea trials in the second half this year.
