The CMA CGM vessel will use an eleven-cylinder version of Wärtsilä’s 92cm low-speed diesel engine X92.
Wärtsilä in a joint venture with Winterthur Gas & Diesel Ltd (WinGD) equips the first container vessel in the new “mega-class” with cargo capacities over 20,000 twenty-foot equivalent units (TEU). The CMA CGM one of the largest and youngest fleets of Reefer containers will use this eleven-cylinder version of the 92cm bore engine.
The vessel is to be built by Hanjin Heavy Industries & Construction (HHIC) in Subic Bay, Philippines. The 200,000dwt vessel will enter service from the fourth quarter of 2017 and will be the largest vessel to date in the CMA CGM fleet.
The huge vessel, one of the largest of Wärtsilä’s Generation X series of engines has a power range from 24,420 to 73,560 kW at 70 to 80 rpm. The engine is designed with low revolutions to enable higher ship propulsion efficiency for large and ultra-large vessels. Using the common rail technology the engine offers low fuel consumption across the entire operating range.
“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”, Says Martin Wernli, CEO of WinGD.
Successful Factory Acceptance Test (FAT):
The engine has passed its design validation and Factory Acceptance Test (FAT) in February 2015. The FAT was held at the Ulsan engine works of Korean licensee Hyundai Heavy Industries. After having done exceptionally well, meeting all its design targets in FAT the engine is shown to have fulfilled all the requirements of the classification societies. The remaining type approval test and sea trials will take place in the second half of this year.
The eight-cylinder versions of the W-X92, to propel a series of four 9,000 TEU post-Panamax container ships being built for Turkish shipowner Ciner Shipping Industry & Trading, will be delivered after the successful completion of all the tests.
