A ferry operated by Norled and powered by a diesel-electric hybrid system and battery power has entered operation along the Norwegian Festøya-Solavågen route.
Built at the Remontowa shipyard in Poland, the Festøya ferry is the first of four SCHOTTEL-equipped hybrid ferries for Norwegian ferry operator Norled.
Each of the four double-ended RoPax ferries feature two SCHOTTEL EcoPellers type SRE 340. These are powered by an innovative diesel-electric hybrid system and operated by green battery power during transit.
The main propulsion for the LMG 120-DEH design vessels consists of electrically driven SCHOTTEL EcoPellers type SRE 340 with 2.1 m diameter fixed-pitch propellers. These thrusters allow economical operation of the newly built vessels at a service speed of 10 kn and a free running speed of 12.5 kn.
The propulsion units are designed to provide full thrust in the required direction, even with strong side winds. SRE’s overall propulsion efficiency and course-keeping stability facilitates low fuel consumption and operating costs, and fewer emissions.
In operating mode, the required power is supplied by two rechargeable battery packs installed onboard. A shore charging system, which also includes an automatic mooring system, recharges these batteries from the mains when the vessels are docked. The vessels only use generators, run on 100 percent biodiesel, in an emergency.
SCHOTTEL reports that this move strengthens its position in the Norwegian ferry market.
The series is set to be completed during this year.
