Ballast water management solutions
Ballast water management solutions mitigate risk of the anthropogenic spread of invasive species across the globe, reducing the affects these species have on both the economy and environment of the receiving ecosystem. 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). Read more »

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.

Environmentally and operationally efficient shaft line solutions
Oil leakage from the shaft line can lead to harm to marine ecosystems, restricted access to ports and potential fines. One solution to comply with environmental regulation is water lubricated seals and bearings, which are already standard in navy installations. Wärtsilä has developed a range of high quality, water and oil lubricated shaft line products and packages that can be used on all vessel shaft sizes. Read more»

Engine power plant solutions
Wärtsilä engine power plant solutions feature very low water consumption and effluent volumes. The focus on reducing the water consumption starts already at the incoming water purification where recycling of reject and effluent will be considered where feasible. The oily water collection and treatment system is an essential part of the engine power plant. The system is designed to minimise constructed areas that can potentially be contaminated with oil or other impurities, resulting in reduced amounts of contaminated rain or washing waters. Before discharging, contaminated water can be either treated on-site by the oily water treatment unit (OWT), separation unit (oil trap) or transported off-site for treatment. Plants without sewer connection can be provided with biological treatment of grey and sanitary waters. Wärtsilä’s Flexicycle power plants with radiators or air cooled condenser (ACC) are often the right choice for arid areas. Thanks to the closed-loop cooling system, water consumption is close to zero. Read more»
