Written by Nick Blenkey
Sandøy is the first fully electric ferry for the Norwegian operator Brevik Fergeselskap and is equipped with two Schottel RudderPropellers.
Equipped with two Schottel RudderPropellers, the 42- by 11-meter Sandøy is the first-fully electric ferry for Norwegian operator Brevik Fergeselskap. Recently launched by Holland Shipyards Group, it will operate operate in the waters of Eidangerfjorden, southeastern Norway, connect Brevik with Sandøya and Bjørkøya.
Designed by Holland Shipyards Group, the new vessel will be completely emission-free and entirely powered by batteries (1,300 kWh). It will be able to accommodate up to 98 passengers and 16 cars.
The two 375 kW type SRP 15O L RudderPropellers are driven by high-efficiency PEM motors. The azimuthing thrusters are designed for heavy duty operation and are therefore equipped with frequency-controlled planetary steering gear and spur wheel steering. They have a propeller diameter of 1.2 meters and the Schottel SDV45 VarioDuct high-efficiency nozzle.
This arrangement allows the vessel to hold its position in extremely strong lateral winds and to sail freely in a high efficiency range.
“We have gained profound experience with hybrid and purely electrically powered vessels,” said Marco Hoogendoorn, Commercial Director at Holland Shipyards Group: “Every vessel is unique and has its own requirements. We are pleased to work with trustworthy partners, like Schottel, that provide us with high quality equipment, which meets the standards we set as a yard.”
