French shipping line CMA CGM has selected Winterthur Gas & Diesel (WinGD)’s 12-cylinder X92DF engines to power its nine new containerships, which boast a world-record capacity of 22,000 TEU.
The vessels are designed to be able to complete Asia-to-Europe voyages using liquefied natural gas.
The 12X92DF engines will be rated 63,840 kW at 80 rpm, making them the most powerful gas and dual-fuel engines ever built.
According to a statement by WinGD, the low nitrogen oxide (NOx) emissions of dual-fuel engines using lean burn combustion, and the low sulphur content of natural gas, mean that CMA CGM is complying with existing and future emissions regulations in choosing the X-DF engines.
The regulations already met by the WinGD X-DF dual-fuel engines include the Iimits on NOx in emission control areas imposed by IMO Tier III and the 0.5% limit on sulphur in fuel, which will be introduced in 2020.
“The built-in efficiency of our lean-burn dual-fuel engines is also complemented by the favourable ratio of carbon-to-hydrogen in methane – the main constituent of natural gas – which mean that our X-DF engines are already low emitters of carbon dioxide compared to liquid fuelled engines,” says Volkmar Galke, general manager of sales at WinGD.
The nine container ships will be built at the yards of Hudong-Zhonghua Shipbuilding and Shanghai Waigaoqiao Shipbuilding. They are due to enter service in 2020.
