Switzerland-based WinGD has unveiled the X-DF-HP, its first high-pressure dual LNG engine, intended to meet the operational demands of ultra-large container vessels (ULCVs).
The development of the dual LNG engine for large ships
This engine was officially presented during Marintec China 2025, a strategic event for the marine industry. The X-DF-HP will be available in X82 and X92 versions, dimensions designed for the segment of vessels with high power, speed and fuel efficiency requirements, and is scheduled for delivery in 2028.
The X-DF-HP is based on the X92-B diesel engine architecture, one of WinGD’s benchmarks in marine propulsion. This evolution integrates
In addition, it is Tier III compliant in both gas and diesel modes, using a conventional selective catalytic reduction (SCR) system, which improves space and operating efficiency.
Amid regulatory uncertainty from the IMO and a scenario with fragmented regulations, LNG remains a viable option for the decarbonization of shipping. The X-DF-HP engine is aligned with the goals of FuelEU Maritime and can operate on renewable methane blends without the need for costly retrofits.
According to WinGD, the X-DF-HP achieves significant improvements in thermal efficiency and greenhouse gas reduction, representing an advance over current dual-fuel models. The platform also allows for future conversions to operate on ethanol, methanol, or ammonia.
This engine is part of WinGD’s portfolio of high-pressure multi-fuel technologies, which includes the X-DF-M/E and X-DF-A series. Thus, operators have a flexible and scalable platform to accompany the shift to fuels with lower environmental impact.
The X-DF-HP represents a cost-effective option for ULCVs choosing LNG as part of their strategy towards net zero.
