The biggest, most powerful dual-fuel engine ever built has received type approval.

Bureau Veritas certified Winterthur Gas & Diesel’s (WinGD) 12X92DF engines, the first series of which is being built by China State Shipbuilding Corp and will power nine ultra-large container ships owned by CMA CGM Group.

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

Klaus Heim, CEO of WinGD, said, “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.”

Dominik Schneiter, vice president for research and development at WinGD, added that the engine outperformed expectations for NOx, SOx and PM emissions.

He said, “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.”
