We improve the sustainability of ferries using proven or innovative systems, and a host of environmental services. We are tackling the challenge of boosting energy efficiency, and are actively finding new ways to reduce emissions. Being an agile technology leader and eager to promote environmentally sound practices, Wärtsilä is pro-active in going beyond environmental regulations.

As environmental regulations continue to evolve, ensuring that effluent is clean and safe is a growing priority. With over 35 years of experience in marine sanitation, Wärtsilä offers innovative solutions that meet all existing and anticipated standards.

We offer a range for achieving SOX and NOX emission reductions. These include multi-fuel engines capable of operating on marine diesel, LNG, bio-fuels and even methanol.

Wärtsilä’s exhaust gas cleaning technology is an economical and environmentally friendly solution for tackling all existing and future SOX emission regulations. It provides a flexible and reliable means for cleaning the exhaust and ensuring global compliance.

The Wärtsilä NOX Reducer utilizes the company’s validated and reliable Selective Catalytic Reduction (SCR) technology for 4-stroke engines. All Wärtsilä systems meet the IMO Tier III requirements for NOX abatement.

Wärtsilä’s waste water processing offer a cost-effective and safe means to avoid discharging waste water to the sea. Our sewage treatment plants are certified to meet IMO MEPC 227(64) guidelines, and are optimised for the treatment of black and grey wastewater flows.

The Wärtsilä Aquarius® Ballast Water Management System range comprises two product series developed to enable our customers to meet their global ballast water discharge regulatory obligations. Both technical solutions have achieved IMO type approval status and have been AMS accepted by the USCG.

In addition we supply Vacuum System Technology, Fresh Water Generation and Oily Water Systems, all aiming to preserve the quality of the world’s oceans.

Increasing pressures on ship operators and port authorities to minimise the impact of air pollution and noise emissions by way of meeting strict environmental regulations are now a worldwide concern.

One particular solution for reducing emissions during port docking is the use of high voltage on-shore power supply systems (HVSC). Wärtsilä has a series of modular HVSC systems provide in-harbour electrical power without the use of auxiliary engines. As a result this solution will enable the vessel to meet upcoming strict clean air regulations (for example, California, USA) when berthed at terminals, without generating harmful noise and air pollutants caused by active diesel engines.

Wärtsilä has been the leading supplier for shaft line solutions for over a century, providing not only excellence, but also reliability and knowhow. We have always been on the front end of environmental sustainability ensuring the best solutions for our customers, offering both standardised and bespoke designs.

Our broad selection of advanced shaft line products are economically sound solutions that are fully compliant with all present and upcoming environmental regulation standards, including the 2013 US EPA Vessel General Permit. The installation of Wärtsilä’s open water lubricated package eliminates all risks of pollution and reduces costs by extending the operational life of the seals and bearings. Our water lubricated solutions ensure continuous and smooth operation of your tail shaft equipment, but also the environmental compliance of your vessel. Whatever the requirement, Wärtsilä can provide a solution.

The Ballast Water Convention will enter into force 8th September 2017, it will ultimately require ships meeting the criteria to install a ballast water management system (BWMS) that is Type Approved in accordance to convention guidelines and conforming to the Regulation D2 discharge performance standard.
