What Wartsila does
Wärtsilä is a Helsinki-headquartered, publicly listed industrial technology company founded in 1834 that designs and manufactures marine and energy systems, primarily large-bore internal combustion engines, propulsion systems, exhaust cleaning systems, and the GEMS energy management platform. The Marine business supplies ship engines, scrubbers, fuel-flexible propulsion, and digital services to shipyards, operators, and cruise and ferry lines, with technology covering conventional fuels, ammonia (Wärtsilä 25), and 100% hydrogen, the last demonstrated in a large-scale engine test in June 2026. The Energy business delivers flexible gas and multi-fuel engine power plants, energy storage solutions, and grid-stabilization services to utilities, IPPs, and increasingly hyperscale data center developers, with carbon capture capability via the OCC solution at 70% CO2 capture rates.
The company operates a global service network of 3,500 field service professionals supporting an installed base covering approximately one in three large vessels worldwide (110,000 connected vessels) and a multi-MW power plant fleet across 180 countries. Revenue is generated through equipment sales, long-term lifecycle service agreements (94% renewal rate in 2025), spare parts, digital services such as Expert Insight predictive analytics and DNV-partnered digital twin fleet management, and performance-based contracts. R&D spend of EUR 329M in 2025 funds the transition to zero-carbon fuels and digital platforms. 2025 net sales were EUR 6,914M, a record year, with the workforce totaling 18,504 employees representing 123 nationalities.
