Winterthur dual-fuel engines to power CMA CGM’s record containerships

Nov 13, 2017 10:01 AM

(WINTERTHUR, Switzerland) — Winterthur Gas & Diesel Ltd (WinGD) has announced that French shipping line CMA CGM, based in Marseille, has chosen WinGD’s largest 92-cm bore, dual-fuel low-speed engines to power what are the largest containerships ever ordered.

The 12-cylinder X92DF engines (12X92DF) will power a series of nine “mega” containerships, each with a record capacity of 22,000 TEU. The vessels ordered by CMA CGM will be built at the yards of Hudong-Zhonghua Shipbuilding (Group) Co. Ltd. and Shanghai Waigaoqiao Shipbuilding Co. Ltd. They are due to enter service in 2020 on routes between Asia and Europe and are designed to have the potential to sail complete Asia-to-Europe voyages on liquefied natural gas (LNG). The 12X92DF engines will be rated 63,840 kW at 80 rpm, making them the most powerful gas and dual-fuel engines ever built.

Beyond leveraging the operating economy and reliability of WinGD’s X-DF engines, with this futuristic move CMA CGM is endorsing the performance of WinGD’s dual-fuel engines with low-pressure gas admission as a way of addressing existing and upcoming regulations from the International Maritime Organization. “Given the low NOx emissions of dual-fuel engines using lean burn combustion and the extremely low sulfur content of natural gas, by choosing our X-DF engines and LNG, CMA CGM is automatically complying with all existing and future emissions regulations,” said Volkmar Galke, general manager of sales at WinGD.

The regulations already met by the WinGD X-DF dual-fuel engines include the Iimits on NOx in Emission Control Areas (ECAs) imposed by IMO Tier III and the 0.5 percent limit on sulfur in fuel which will be introduced in 2020, as well as possible limits on particulates. “The built-in efficiency of our lean-burn dual-fuel engines is also complemented by the favorable 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 CO2 compared to liquid-fueled engines,” Galke said. “Our X-DF engines are thus an excellent starting point for playing a full part in achieving the 30 percent improvement in overall vessel efficiency up to 2025 specified by the IMO’s Energy Efficiency Design Index (EEDI).”

Looking at the overall total cost of ownership (TCO) of the new vessels, as well as operating expenditure (OPEX), capital expenditure (CAPEX) is also reduced because the emissions levels of WinGD X-DF engines are achieved without the need to install exhaust gas aftertreatment systems, and by the application of the low-pressure gas admission feature of the X-DF engines, which uses less expensive, more energy-efficient gaseous fuel compression equipment compared with low-speed dual-fuel engines requiring high pressure gas injection. In addition, WinGD’s Generation X engines feature a series of designed-in measures which target increased ease of maintenance.
