Norwegian ferry operator Torghatten Trafikkselskap has selected the German SCHOTTEL Rudder EcoPeller (SRE) for retrofit on its double-ended ferry.
The ferry will feature two four-bladed SRE’s type SRE 340 L CP, each with an input power of 750 kW. The EcoPellers will be driven by electric motors. In operating mode, the required power will be supplied by battery packs installed onboard, which will be recharged from the land grid during the stays on the quay.
Gunnar Heringbotn, technical manager at Torghatten Trafikkselskap commented: “We have already equipped several of our ferries with SCHOTTEL propellers. For the electrification of the ‘Torghatten’, we have opted for the SRE, as it optimally meets our requirements and supports us on our way to an eco-friendly future. Thanks to the tailor-made modernisation concept, downtimes can be kept as short as possible.”
Since it is possible to integrate the SCHOTTEL solution into the existing steel structure of the former propulsion system, no hull changes or major steel work will be necessary. Beyond this, the work can be carried out by a local shipyard, reducing installation efforts and shortening downtime.
To be environmentally compliant, the propulsion system of the Norwegian ferry will be equipped with the patented and DNV-GL type-approved SCHOTTEL LEACON sealing system. Through the use of separate seals on the seawater side and on the gearbox side, the sealing system ensures that, in case of leakage, seawater entering the system or gear oil escaping from the system are collected in an intermediate chamber. This prevents water from entering the gearbox and, of even greater importance, oil from escaping into the seawater.
