With the pet cat currently out of the bag on CMA CGM’s strategy to make use of cleaner-burning dissolved gas to power its 9 record-setting 22,000 “mega” containerships, we’re currently discovering more regarding the massive engines that will certainly be made use of to power what are presently the biggest containerships ever before purchased.

On Monday, Switzerland- based Winterthur Gas & & Diesel Ltd (WinGD) disclosed it has actually been picked to provide the 12-cylinder, 92 centimeters birthed, dual-fuel low-speed major engines (12X92DF) that perseverance the ships.

The 12X92DF engines will certainly be ranked to 63,840 kW at 80 rpm, making them one of the most effective gas as well as dual-fuel engines ever before constructed, according to WinGD.

CMA CGM’s choice to make use of LNG gas comes in advance of upcoming international policies targeted at lowering the optimum sulphur material of maritime gas from 3.5% to 0.5% by 2020.

The business authorized shipbuilding agreements with China State Shipbuilding Corporation (CSSC) Group for the 9 record-breaking ships inSeptember The vessels will certainly be built at Hudong-Zhonghua Shipbuilding (Group), Shanghai Waigaoqiao Shipbuilding, as well asChina Shipbuilding Trading Co (CSTC), as well as are because of go into solution in 2020 on paths in between Asia as well as Europe.

CMA CGM claims that by utilizing LNG gas over conventional hefty gas oil, the ships will certainly produce as much as 25% much less carbon dioxide as well as will virtually get rid of almost all sulphur as well as great bit issue, together with lowering nitrogen oxides exhausts by regarding 85%. Moreover, the Energy Efficiency Design Index (EEDI), which determines a ship’s ecological impact, is boosted by 20% contrasted to ships powered specifically by gas oil.

“Given the low NOx emissions of dual-fuel engines using lean burn combustion and the extremely low sulphur content of natural gas, by choosing our X-DF engines and LNG, CMA CGM is automatically complying with all existing and future emissions regulations,” claims Volkmar Galke, General Manager of Sales at WinGD.

Specifically, by utilizing LNG gas, the vessels will certainly currently fulfill policies enforced by the IMO Tier III discharge criteria as well as the 0.5% restriction on sulphur in shelter gas, which will certainly be presented in 2020, in addition to feasible limitations 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 fuelled engines,” includedGalke “Our X-DF engines are thus an excellent starting point for playing a full part in achieving the 30% improvement in overall vessel efficiency up to 2025 specified by the IMO’s Energy Efficiency Design Index (EEDI).”
