LPG ‘Pre-? t’ Option for WinGD X-DF-A

WinGD introduced an option for its X-DF-A ammonia- fuelled engines to be delivered capable of running on liqui- ? ed petroleum gas (LPG), a ‘pre-? t’ solution that could be of interest to vessels under construction for the anticipated global trade in ammonia, which will also be capable of trans- porting LPG.

Named X-DF-P for the propane that is LPG’s primary component, the solution will be released to enable ? rst en- gine deliveries in 2027, when operators are likely to be con- sidering in detail their anticipated balance between the LPG and ammonia trades. The engine, designed and optimized for ammonia fuel, will offer reliable and ef? cient running on

LPG, with a minor modi? cation preparing it to run on am- monia at a later date.

Engine sizes under development are those typically used by trade-relevant vessels, including 52- and 62-bore.
