WinGD has launched a new high-pressure LNG dual-fuel engine designed for ultra-large container vessels. The development comes at a time when shipowners are seeking fuel flexibility in a fragmented regulatory landscape. The company says the engine offers higher efficiency and a practical compliance route for the decade ahead.
WinGD has presented its first high-pressure LNG dual-fuel engine, the X-DF-HP, during Marintec China 2025, marking an expansion of its propulsion portfolio for the ultra-large container vessel segment. The timing reflects the uncertainty facing owners as global climate rules shift and regional requirements take on greater influence. With the International Maritime Organization’s Net Zero Framework currently paused, demand for LNG-capable vessels has continued to grow.
The new engine will be available in X82 and X92 bore sizes, with first deliveries expected in 2028. It has been developed to meet the power, efficiency and fuel flexibility requirements of the largest container ships. WinGD says the high-pressure dual-fuel concept is expected to deliver improved efficiency when compared with similar dual-fuel designs.
“Large container vessels present a unique propulsion challenge,” said Benny Hilström, Vice President, Market Development at WinGD. “They demand immense power, exceptional efficiency and long-term fuel flexibility. With the X-DF-HP, we are providing operators with a purpose-built solution for the most power-hungry vessels, offering uncompromised, trouble-free propulsion.”
WinGD has designed the engine to work with the same auxiliary system requirements as other recognised concepts, easing installation and integration for shipyards. It meets Tier III compliance in both gas and diesel modes using a standard SCR, which the company says gives owners a practical and space-efficient choice during newbuild planning.
The X-DF-HP builds on the established high-pressure Diesel X92-B platform. Sebastian Hensel, Vice President R&D at WinGD, said the design benefits from long-standing experience with both diesel and dual-fuel technologies. “The X-DF-HP is built on the high-pressure Diesel X92-B engine platform that has already proven itself as one of the most efficient and reliable large-bore solutions in the container segment,” he said. “Building on our long-standing diesel engine expertise and our deep experience in LNG dual-fuel technology, we’ve developed the X-DF-HP. Our tests and simulations show the X-DF-HP will deliver a clear step up in fuel efficiency and GHG performance compared to existing high-pressure dual-fuel engines on the market.”
The new engine sits within WinGD’s broader multi-fuel roadmap, which includes options for methanol, ethanol and ammonia. Established engines such as the X92-B can also be retrofitted for high-pressure LNG and other future fuels as pathways evolve.
With LNG expected to remain a compliant and commercially viable option under FuelEU Maritime into the next decade, WinGD believes the X-DF-HP will appeal to operators seeking a lower-risk route to emissions reduction. “For ultra-large container vessels choosing LNG as their pathway to net zero, the X-DF-HP is the most cost-effective option,” Hilström added. “For all other vessels, the low-pressure X-DF platform continues to deliver the best lifecycle economics.”
The company expects the new engine to strengthen its position in the container sector as vessel owners prepare for long-term changes to global energy and fuel requirements.
