WinGD (Winterthur Gas & Diesel) has received type approval for the biggest and most powerful LNG-powered engines ever built. Class society Bureau Veritas awarded the approval for WinGD’s dual-fueled 12X92DF engines, the first series of which is currently being built by China State Shipbuilding Corp (CSSC) and will power nine ultra-large containerships (ULCS) owned by the CMA CGM Group, a world leader in shipping and logistics. These vessels will become the largest containerships powered by LNG and represent a significant step on the path to the energy transition of the shipping industry.
The type approval was awarded following a series of extensive full-load tests in diesel and gas operation. A virtual ceremony took place on May 26 with guests joining from Beijing, Shanghai, Marseille, Paris and Winterthur.
“The certification ceremony marks a new stage in the construction of our nine 23,000-TEU LNG-powered vessels, the world’s largest containerships powered by LNG. CMA CGM’s ground-breaking choice in favor 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,” said CMA CGM in a statement.
Olivier Cartier, Technical Vice President, Bureau Veritas, commented: “The certification process of WinGD’s 12X92DF engine was a long process due to the size and complexity of the engine. We mobilized our worldwide teams of engine specialists, especially in China, France and 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.”
“With the type approval of our biggest engines to date, we are opening up the possibilities of LNG-fueled ship propulsion to yet another vessel segment, a testament to its cost-efficiency, reliability and sustainability,” said Klaus Heim, WinGD CEO. “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 its 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, Vice President, for Research and Development at WinGD.
