A concept for a series of innovative shuttle ferries, featuring zero or[ds_preview] low emissions, is being launched by Wärtsilä. The ferries are designed to run on batteries or in a battery-engine hybrid configuration with fuel options LNG or biofuel.
The concept has been developed through cooperation between Wärtsilä’s Ship Design and Electrical & Automation offices, the company says. The design characteristic 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 % compared to conventional installations, and all local emissions are completely eliminated. With the plug-in hybrid configuration, emissions are reduced by up to 50 %, the company states.
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 an electrical and automation package based on the company’s battery/hybrid solution and includes Wärtsilä azimuth propulsion and bridge control system.
The concept has been developed in line with the Norwegian government’s new environmental regulations for ferries emphasising the elimination of harmful emissions.
