Swiss marine propulsion company WinGD has signed three long-term service agreements covering a total of 14 LNG carriers powered by X-DF dual-fuel technology. The contracts were signed with COSCO Shipping LNG (Hong Kong) Ship Management, NYK LNG Shipmanagement and TMS Cardiff Gas, and cover vessels fitted with different generations of this technology.
Contract details
The agreement with COSCO runs for ten years and covers six LNG carriers fitted with WinGD 6X72DF engines. With NYK LNG Shipmanagement, a five-year contract was signed for ten X-DF engines across five vessels: two of them, built in 2022 and 2024 by HHI and SHI respectively, are fitted with 5X72DF engines, while the other three, built in 2025 and 2026 by HHI, are equipped with the 5X72DF-2.1 version. The third contract, a long-term agreement with Athens-based TMS Cardiff Gas, covers three newbuild LNG carriers built by HD Hyundai Samho in South Korea, each fitted with two WinGD 5X72DF engines.
Statements from WinGD
Benny Hilström, Vice President of Market Development at WinGD, said these agreements reflect the growing importance operators place on long-term lifecycle support provided directly by the original engine designer, noting that the LNG market depends on timely, safe and reliable deliveries, which makes fleet performance critical. For his part, Carmelo Cartalemi, Head of Strategic Marketing at WinGD, pointed out that no one understands X-DF engines like those who designed them, highlighting the company's accumulated experience in supporting this equipment throughout its service life.
Scope of service
The contracted maintenance package includes the supply of spare parts for scheduled overhauls, field technical support, workshop services and specialist advice, complemented by remote monitoring, fault diagnosis and engine performance optimisation through WinGD's WiDE digital platform. According to the company, the combination of hands-on maintenance and continuous digital analysis makes it possible to plan technical interventions and optimise engine operation according to each vessel's operating profile.
These new contracts add to the Global Service by WinGD programme, launched in 2025, which combines more than 125 years of experience in two-stroke engine design with a worldwide network of technical service, spare parts and digital support. WinGD is headquartered in Winterthur, Switzerland, and traces its origins back to the Sulzer diesel engine business, established in 1893.
