Wärtsilä Oyj Abp is a global leader in advanced technologies and lifecycle solutions for the marine and energy markets. The company operates through two primary segments: Marine and Energy. The Marine segment provides engines, propulsion systems, hybrid technology, and integrated powertrain systems for merchant vessels, gas carriers, cruise ships, ferries, and naval vessels. It also offers marine systems such as exhaust treatment, gas solutions, and shaft line solutions, alongside voyage optimization software. The Energy segment delivers flexible power plants (running on gas, multi-fuel, and sustainable fuels), energy storage systems (including the Quantum battery energy storage system), and the GEMS digital energy management platform. A significant portion of Wärtsilä's revenue—over 50%—is generated from its high-margin services business, which includes spare parts, maintenance, lifecycle upgrades, and performance optimization. Geographically, the company has a vast global footprint with operations in over 70 countries. Wärtsilä's competitive position is underpinned by its strong R&D focus on decarbonization, pioneering the development of engines capable of running on future fuels like methanol, ammonia, and hydrogen, thereby supporting the green transition in both the maritime and energy sectors.
