Winterthur Gas & Diesel (WinGD) is a leading developer of low-speed gas and diesel engines for marine propulsion. Headquartered in Switzerland, since its inception as the Sulzer Diesel Engine business in 1893, it carries on the legacy of excellence in design. 

Today our innovative technology is behind the propulsion power of all types of deep-sea ships world-wide, such as oil and product tankers, bulk carriers, car carriers, general cargo ships and container ships. WinGD continues the tradition of the Sulzer diesel engine  and the Wärtsilä two-stroke engine as a leading developer of low-speed gas and diesel engines.

Headquartered in Winterthur, Switzerland, the largest team of WinGD employees, located there, contribute to  all aspects of research and development (R&D), design, operational and manufacturing support, marketing and sales.

In Switzerland, WinGD also hosts an extensive state-of-the-art research and training facility at its Swiss Engine Research & Innovation Centre.

With offices and operations worldwide, WinGD employees represent over 25 different nationalities.  This diverse culture provides rich innovation and progressive thinking.

    WinGD look to liquids in quest for clean fuels

    2020-04-07T16:35:00Sponsored by

    The internal combustion engine will continue to dominate marine propulsion long beyond 2050, but which fuels will propel shipping into a cleaner future? One likely pathway will see ships with gas-fuelled engines burning first LNG then carbon-neutral biomass and synthetic methane as they become available. That route to decarbonisation is ...
