SCHOTTEL ECO-PELLERS FOR NORLED HYBRID FERRIES

Thursday, August 20, 2020 

'Fest°ya', first of a total of four hybrid ferries for Norwegian ferry operator Norled, each equipped with two Schottel SRE 340 EcoPellers, has recently entered operation.

The double-ended ro-pax ferries are being built at the Remontowa shipyard in Poland, and are powered by an innovative diesel-electric hybrid system, operated by green battery power during transit. Schottel says this further strengthens its position in the Norwegian ferry market.

The main propulsion for the LMG 120-DEH design vessels is by electrically driven Schottel EcoPellers with 2.1m diameter fixed-pitch propellers, allowing economical operation at a service speed of 10 knots and a free running speed of 12.5 knots. The propulsion units are designed to provide full thrust in the required direction, even with strong side winds. Thanks to the SRE’s overall propulsion efficiency and course-keeping stability, it is characterised by low operating costs and low fuel consumption, resulting in low emissions.

In operating mode, the required power is supplied by two rechargeable battery packs installed on board. A shore charging system, which includes an automatic mooring system, recharges these batteries from the mains when the vessels are docked. The vessels' generators, which run on 100% biodiesel, are only used in an emergency.

Two of the 114.4m long and 17.7m wide Norled ferries will service the Festøya-Solavågen route and are capable of taking on board up to 120 cars and 296 passengers. The other two vessels will operate the Mannheller-Fodnes route and are certified to carry more, with a maximum of 395 passengers. The series is set to be completed during this year.
