WinGD’s 12X92DF engine, designed to operate on LNG, has been awarded the Guinness World Records® title as the most powerful commercially available otto-cycle engine.
The 12X92DF engine, first built in 2019, completed tests at engine builder CSSC-MES Diesel Co (CSSC-CMD) and now officially holds the title: “Most powerful marine internal combustion engine (otto cycle) commercially available”. The 2,140-tonne unit generated power of 63,840 kW at a speed of 80 rpm.
The engines are being installed on nine 23,000-TEU container ships being built at three China State Shipbuilding Corporation yards for French container line, CMA CGM. The first vessel in the series was delivered in September 2020.
Supplied with LNG from 18,600m3 tanks, the vessels will be capable of completing an entire round trip between Asia and Europe without re-fuelling. They are currently the world’s largest LNG-powered vessels.
“The future uptake of LNG as a marine fuel is being driven by large merchant vessels with two-stroke engines where the savings – and the environmental benefits – are the greatest,” declared Klaus Helm, WinGD’s CEO. “We are delighted with this achievement, which was made possible by CMA CGM’s strong vision and close cooperation with engine builder CSSC-CMD and Bureau Veritas. The 12X92DF is not just the biggest dual-fuel engine in our portfolio – it is now officially the most powerful of its type in the world.”
More than 100 X-DF engines currently in operation have logged in excess of one million running hours and close to 400 such units are currently on order.
