Improvements in efficiency

Fleet efficiency
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, making the crew and the operations centre 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 emission system for the entire vessel is achieved by combining optimised ship design with Wärtsilä's knowledge of automation, machinery, propulsion, and control systems. Wärtsilä has developed numerous efficiency concepts, such as the Electric Propulsion Systems Low Loss Concept (LLC) and Low Loss Hybrid (LLH). Wärtsilä also offers vessel and voyage efficiency optimisation services that improve energy efficiency, reduce emissions and costs, and help make the best possible decisions for asset management and voyage performance.

Power plant efficiency
Wärtsilä 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 by adding hybrid solutions, FlexicycleTM solutions (steam combined cycles), combined heat and power (CHP), trigeneration (power, heat and cooling), and also through Wärtsilä lifecycle solutions, which ensure that the power plant operates in the most energy-efficient way and in accordance with regulations. Wärtsilä also offers tools for the smart integration of energy production and storage at the 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 31 engine has the best 4-stroke engine fuel economy in the world. The Wärtsilä 31SG is the newest gas engine we offer, taking efficiency to a new level for internal combustion engines.

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

Reducing emissions to air

CO2 and other greenhouse gas (GHG) emissions
Wärtsilä focuses on the development of technologies that reduce GHG emissions in numerous ways. These include, among others, gas and multi-fuel engines, as well as solutions for environmentally advanced vessels, voyage optimisation, and energy storage. Wärtsilä's flexible energy solutions enable a transition towards a 100% renewable energy future. At the system level, GHG emission reduction is achieved by enabling the optimal integration of renewable energy sources and the use of renewable fuels.

SOx emissions
Wärtsilä provides several solutions to help customers reduce emissions of SOx and comply with local and global regulations. Wärtsilä's technology development supports solutions that enable the use of fuels with different sulphur contents, as well as systems that clean sulphur from exhaust gas and enable the use of alternative fuels with close to zero sulphur content, e.g. natural gas. Wärtsilä exhaust gas cleaning systems (EGCS) not only reduce SOx emissions but also remove large levels of particulate matter (PM) and black carbon. The Wärtsilä EGCS can be customised for both the 0.1% limit in Emission Control Areas (ECA) and the global 0.5% cap agreed within the IMO. 

NOx emissions
All Wärtsilä marine engine portfolio products are IMO NOx Tier II compliant. Wärtsilä solutions for IMO NOx Tier III compliance are Selective Catalytic Reduction (SCR), dual-fuel engines in gas mode, and pure gas engines (Wärtsilä 31SG). The NOx emission levels of Wärtsilä stationary engine-based power plants are low enough to meet the most current environmental regulatory requirements. To comply with even the strictest environmental regulations, Wärtsilä offers solutions such as SCR.  

Protecting the marine environment

Ballast water management systems                           
Wärtsilä's Aquarius range of IMO and USCG approved Ballast Water Management Systems (BWMS) limit the spread of ballast water related invasive species and prevent their introduction to aquatic ecosystems. The Aquarius BWMS range offers both Ultraviolet UV (USCG type approved) and Electro Chlorination EC technology (USCG type approved).

Waste treatment
Wärtsilä offers a complete, fully integrated wet and dry waste treatment system suitable for all vessel types and sizes. Wärtsilä’s innovative advanced waste water treatment technology, with external membrane separation, is based on biological degradation. The system allows for the high purity treatment of black and grey water in accordance with the most stringent global legislation, including the removal of nutrients such as phosphorous and nitrogen compounds, as required for special areas such as the Baltic Sea and Alaskan waters. Wärtsilä’s waste management product range also includes vacuum toilets and collection systems, food waste collection & treatment systems, solid waste handling, drying and incineration, and sewage treatment plants.
