The biggest and most powerful liquefied natural gas (LNG)-fueled engine ever built has received type approval from classification society Bureau Veritas (BV), Switzerland-based engine manufacturer Winterthur Gas & Diesel (WinGD) said on Wednesday.

BV 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 container ships (ULCS) -- the largest ever powered by LNG -- owned by French carrier CMA CGM Group.

The type approval was awarded following a series of extensive full-load tests in diesel and gas operation.

Olivier Cartier, Technical Vice President, Bureau Veritas, commented on the approval: “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, 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.”

A virtual ceremony on May 26 with guests joining from Beijing, Shanghai, Marseille, Paris and Winterthur marked the landmark moment for the engine technology, which has brought the use of LNG as a marine fuel into an entirely new vessel sector.

“The certification ceremony marks a new stage in the construction of the CMA CGM’s nine 23,000-TEU LNG-powered vessels,” CMA CGM said in a statement. “CMA CGM’s groundbreaking 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.”

“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 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, Vice President, for Research and Development at WinGD.

The development of the X92DF engine builds on the expertise and experience gained from more than 500,000 operating hours for WinGD’s X-DF dual-fuel engine technology, the company said. That landmark comes just under four years since the first engine went into service, highlighting the rapid uptake and remarkable reliability of WinGD’s low-pressure concept.

WinGD said it has received 320 orders for its X-DF engines including 60 in operation. The X-DF has been the best-selling dual-fuel low-speed engine technology in the maritime market since the second half of 2017. As well as the first gas-fueled ULCSs, WinGD’s low-pressure X-DF technology also powers the first LNG-fueled Aframax shuttle tankers with VOC recovery and very large crude oil carriers.
