Engine manufacturer WinGD said its 12X92DF dual-fuel engine has received official recognition as the most powerful dual-fuel engine ever built
In tests carried out at engine builder CSSC-MES Diesel and verified by Guinness World Record for the official record title of ‘Most powerful marine internal combustion engine (Otto cycle) commercially available’, the 2,140-tonne engine demonstrated a power of 63,840 kW at a speed of 80 rpm.
WinGD said the super-sized engines fuelled from 18,600-m3 tanks will propel nine 23,000-TEU container ships operated by French shipping and logistics company CMA CGM.
CMA CGM is the first shipowner to operate ultra-large containers using LNG, making these ships the world’s biggest LNG-powered vessels.
WinGD chief executive Klaus Heim said “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. We are delighted with this achievement, which was made possible by CMA CGM’s strong vision and close co-operation 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.”
The 12X92DF engine was introduced in 2019 and demonstrates the viability of scaling a lean-burning combustion cycle to larger engine sizes. The X-DF range of dual-fuel engines enables the use of LNG as a marine fuel. The engine series draws on design and field experience earned through an installed base of more than 100 X-DF engines logging nearly 1M running hours with almost 400 X-DF engines on order.
Class society Bureau Veritas awarded the dual-fuelled 12X92DF engines type-approval in May 2020 following a series of full-load tests in diesel and gas operation.
