WinGD Engines to Power LNG Fueled Box Giants

66

CMA CGM’s LNG fueled box giants are all set to be powered by Winterthur Gas & Diesel Ltd.

The WinGD engines comprise of a 12-cylinder X92DF engines (12X92DF) to power the nine 22,000 TEU LNG fueled containerships stationed in China.

Largest engine designed:

The 92 cm bore, dual-fuel low-speed engines are WinGD’s largest engine to be developed and operated on the lean burn Otto combustion process with low-pressure gas admission and micro-pilot ignition.

The CMA CGM ships are the largest containerships thus far ordered and the 12X92DF engines will be the most powerful gas and dual-fuel engines ever built, rated at 63,840 kW at 80 rpm.

Compliance with regulations:

Volkmar Galke, General Manager of Sales at WinGD said, “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”.

CMA CGM’s Ludovic Gérard, Vice President of Owned Fleet further added, “With this move to LNG energy, CMA CGM is moving ahead for a greener shipping. We selected WinGD engines for the main propulsion on the grounds of their experience in dual-fuel engines and our positive feedback on the two-stroke Generation X engines”.

The regulations have already been 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% limit on sulfur in fuel which will be introduced in 2020, as well as possible limits on particulates.

Efficiency enhanced by fuel ratio:

Galke further added, “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. 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)”.

The following are key points highlighted by WinGD:

  • The overall Total Cost of Ownership (TCO) of the new vessels, as well as operating expenditure (OPEX), capital expenditure (CAPEX) is also reduced
  • This is possible because the emissions levels of WinGD X-DF engines are achieved without the need to install exhaust gas after-treatment systems, and by the application of the low-pressure gas emission feature of the X-DF engines
  • The engine is less expensive, more energy-efficient gaseous fuel compression equipment compared with low-speed dual-fuel engines requiring high pressure gas injection.
  • Generation X engines feature a series of designed-in measures which target increased ease-of-maintenance

With the help of all the features specified above, WinGD expects to increase its market share since the introduction of its new diesel and dual-fuel engines.

Huge numbers of orders placed:

The company has received more than 75 orders for its X-DF engines since their introduction to the market at the end of 2013. Besides being hugely popular in LNG carriers for main propulsion, the orders received for cargo vessels has also increased in 2017, with over 25 engine orders received in the year to date.
