French shipping giant CMA CGM has chosen Winterthur Gas & Diesel’s (WinGD) dual-fuel low-speed engine to power what are presently the largest containerships ever ordered.
The 12-cylinder X92DF engines (12X92DF) will power the series of nine containerships, all exceeding 22,000 TEU in capacity and ordered by CMA CGM at Chinese yards, Hudong-Zhonghua Shipbuilding (Group) Co., Ltd.and Shanghai Waigaoqiao Shipbuilding Co., Ltd. earlier this year.
WinGD’s dual-fuel engines will feature low-pressure gas admission to address existing and upcoming regulations from IMO, the company said. The regulations already met by the engines include the limits on NOx in Emission Control Areas (ECAs) imposed by IMO Tier III and the 0.5% limit on sulphur in fuel which will be introduced in 2020, as well as possible limits on particulates.
The engines also support the 30% improvement in overall vessel efficiency up to 2025 specified by the IMO’s Energy Efficiency Design Index (EEDI).
CMA CGM’s boxships 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).
