WinGD Launches X‑DF‑HP High‑pressure LNG Dual‑fuel Engine for Ultra‑large Container Vessels

WinGD, the Swiss marine‑power specialist, unveiled its first high‑pressure LNG dual‑fuel engine, the X‑DF‑HP, at Marintec China 2025. The engine is aimed at ultra‑large container vessels (ULCVs) and will be offered in X82 and X92 bore sizes, with deliveries slated to start in 2028.

Key points:

• Regulatory context: Shipowners face a shifting landscape—IMO’s Net Zero Framework is on hold, while regional emissions rules diverge;
• Performance claims: WinGD says the X‑DF‑HP delivers higher efficiency than conventional diesel engines and comparable dual‑fuel designs, meeting Tier III standards in both gas and diesel modes using a standard SCR system;
• Installation ease: Auxiliary systems (e. g., fuel‑supply pressure) mirror those of existing engine families, simplifying shipyard integration;
• Fuel flexibility: The engine can run on high‑pressure LNG and is compatible with renewable methane blends, supporting FuelEU Maritime compliance for the next decade. Existing models like the X92‑B can be retrofitted for LNG or other alternative fuels;
• Strategic fit: The X‑DF‑HP expands WinGD’s high‑pressure, multi‑fuel portfolio, which already includes engines for methanol, ethanol, and ammonia.

Benny Hilstrom (Market Development VP) highlighted the need for “immense power, exceptional efficiency and long‑term fuel flexibility” on the world’s largest container ships, positioning the X‑DF‑HP as a “purpose‑built, trouble‑free propulsion” solution.

Sebastian Hensel (R&D VP) noted that the engine builds on the proven high‑pressure diesel X92‑B platform, leveraging WinGD’s diesel expertise and LNG dual‑fuel experience.

The launch follows WinGD’s October announcement of an ethanol‑fuelled two‑stroke marine engine slated for delivery in 2027, underscoring the company’s broader push toward alternative marine fuels.
