Improving efficiency

Fleet efficiency
The Wärtsilä Fleet Operations Solution (FOS) is designed to achieve the highest level of safety at sea, increase fleet efficiency, and simplify everyday tasks both ashore and on board. FOS unites all navigational processes and voyage data on a single platform, allowing the crew and the operations centre to work as one. FOS offers improved operational processes relating to fleet performance, voyage planning and execution, weather routing, and ship-to-shore reporting in compliance with environmental regulations such as EU-MRV and IMO-DCS.

Total vessel and voyage efficiency
An efficient and low-emissions system for the entire vessel is achieved by combining an optimised ship design with our knowledge of automation, machinery, propulsion, and control systems. We have developed numerous efficiency concepts, such as the Low Loss Concept (LLC) and Low Loss Hybrid (LLH) for electric propulsion systems. We also offer vessel and voyage performance optimisation services that improve energy efficiency, reduce emissions and costs, and help make the best possible decisions for asset and voyage management.

Power plant efficiency
Wärtsilä’s engine-based power plants offer the highest single cycle efficiencies with outstanding flexibility using a broad range of fuels. Total plant efficiency can further be improved and optimised through hybrid solutions, Flexicycle solutions (steam combined cycles), combined heat and power (CHP) solutions, tri-generation (power, heat, and cooling) solutions, as well as by our lifecycle solutions, which ensure that the power plant operates in the most energy-efficient way and in compliance with regulations. Our offering also includes tools for the smart integration of energy production and storage at system level.

Engine efficiency improvements
A long-term focus on improving engine efficiency has resulted in Wärtsilä engines having the highest efficiency ratings among existing prime movers. A key success factor has been the development of integrated engine functionalities that enable low emissions and high engine efficiency. The Wärtsilä 31SG is the latest gas engine in our portfolio, taking efficiency to a new level for internal combustion engines.

Propulsion efficiency upgrades
Propulsion products incorporate environmental features and are critical in terms of the overall environmental impact of the vessel. Our propulsion units and energy saving solutions, such as the Wärtsilä EnergoFlow, result in significant fuel efficiency improvements of up to 10% while reducing NOx and CO2 emissions.
