WinGD completes type approval testing for new engine

Swiss marine power company WinGD has completed testing for its X52-S2.0 engine for medium-bore two-stroke engines.

The tests at Yuchai Marine Power Co (YCMP) confirmed the engine’s performance and compliance, while the prototype project validated its ease of assembly and maintenance.

The X‑S series succeeds the RT‑flex50 and RT‑flex58 engines and is available in 52 centimetres and 62 centimetres bore sizes, with confirmed orders already for diesel, LNG and methanol configurations and an ammonia fuel option under development.

The new engine is intended for vessels that need a compact, medium-bore solution due to its combination of a small footprint and best-in-class fuel efficiency. It offers around 10g/kWh lower fuel efficiency than equivalent RT-flex engines, resulting in a saving of around 4 per cent depending on the operating profile.

WinGD Head of Global Testing & Validation, Sotiris Topaloglou said: “The recent test campaign of this newest X-S engine has confirmed that this series delivers exceptional fuel efficiency and emissions performance.

“We’re proud of the innovations that have enabled this performance. The footprint reduction will drive cost efficiencies while the new concept dramatically simplifies engine construction, installation, maintenance and service.

“Completing this prototyping and testing phase so efficiently was only possible thanks to our strong partnership with YCMP.”

The type approval tests followed similar successful tests for the larger X62-S2.0 engine at Dalian Marine Diesel in April. The first order for the X52-S2.0 was received in February 2023 followed by a second order with iSCR, WinGD’s on-engine NOx abatement solution, in July 2023.

In May, WinGD received another order for its X-DF-A ammonia-fuelled engines, which will power the world’s first ammonia dual-fuel Aframax tankers.

More recently, WinGD and Japanese shipbuilder and technology developer, Mitsubishi Shipbuilding Co., Ltd., completed the initial design of an ammonia fuel supply system (AFSS) for vessels powered by WinGD’s X DF A ammonia-fueled engines.
