WinGD (Winterthur Gas & Diesel) has received type approval for the biggest and most powerful LNG-fuelled engines yet built, the 12X92DF, currently in build at China State Shipbuilding Corp (CSSC) to power the first of nine ultra-large container ships (ULCS) owned by CMA CGM.

The vessels will become the largest container ships powered by LNG and represent a further step on the path to the energy transition of the shipping industry. The type approval was awarded by Bureau Veritas following a series of extensive full-load tests in diesel and gas operation.

A CMA CGM representative said: “The certification ceremony marks a new stage in the construction of the CMA CGM’s nine 23,000-TEU LNG-powered vessels. These vessels are the world’s largest containerships powered by LNG. CMA CGM’s ground-breaking choice in favour of LNG is a major step forward and a clear illustration of our resolute commitment to environmental protection and to the energy transition of the maritime industry. This certification is a major milestone as it marks the recognition of the technological efficiency of our dual-fuel engine project.”

Olivier Cartier, BV Technical VP, said: “The certification process of WinGD’s 12X92DF engine was a long process due to the size and complexity of the engine. We mobilised our worldwide teams of engine specialists, especially in China, in France and in Germany, at each of the critical phases of the certification process.  Progressive Type Approval Tests were necessary where at each test significant progress and refinement were noted, so that we remained confident that final certification at 100% of the power using gas as fuel was an achievable objective – and this has now been achieved.”

Klaus Heim, WinGD CEO said: “With the type approval of our biggest engines to date, we are opening up the possibilities of LNG-fuelled ship propulsion to yet another vessel segment, a testament to its cost-efficiency, reliability and sustainability. This is an important step towards the sustainable energy transition within the shipping industry and we are incredibly proud of the role WinGD plays in this journey.”

“WinGD’s X92DF engines offer the most sustainable emissions footprint currently available, outperforming expectations for NOx, SOx and PM emissions and with CO2 levels over 20% lower than typical diesel engines. With it’s unique combination of Otto (lean burn) and Diesel cycle technology these engines can adapt for any of the potential sustainable fuels of the future making them a secure asset for a long time to come.” added Dominik Schneiter, VP Research and Development, WinGD.

The X92DF engine builds on experience from more than 500,000 operating hours for WinGD’s X-DF low pressure dual-fuel engine technology, since the first engine went into service nearly four years ago. WinGD has received 320 orders for X-DF engines, with 60 in operation.
