W?rtsil? Introduces Zero Emissions Ferry Concept

A complete concept for a series of innovative and cost effective shuttle ferries, featuring zero or low emissions, has been launched by Wärtsilä. 

The design focuses on high energy efficiency with low resistance, both above and below the water line. The ferries are designed to run entirely on batteries or in a battery-engine hybrid configuration where the fuel options are LNG or biofuel. 

In plug-in operation, the fuel consumption is reduced by 100 percent compared to conventional installations, and all local emissions are completely eliminated. With the plug-in hybrid configuration, emissions are reduced by up to 50 percent.

The concept features Wärtsilä's new wireless inductive charging system, which for typical shuttle ferry operations involving 20,000 or more departures a year is considered a notable benefit because of its time and energy savings. The system eliminates physical cable connections, thus reducing wear and tear and enabling charging to begin immediately when the vessel arrives at quay.

The design also encompasses a complete electrical and automation package based on the company's battery/hybrid solution. It also includes Wärtsilä azimuth propulsion units and a complete bridge control system. The ferry series can accommodate 60 to 120 cars on a single car deck for quick and easy loading and unloading.

The ferry concept has been developed in line with the Norwegian government's new environmental regulations for ferries emphasizing the elimination of harmful emissions. This trend is also evident in a number of other countries.

In addition to this design concept for newbuilds, Wärtsilä can also provide battery and hybrid solutions for retrofitting existing ferry propulsion units in order to meet the new regulations.
