Two examples of Schottel's SRE 360 controllable-pitch propeller are slated for installation on a new 64-metre inspection vessel being built for the Danish Fisheries Agency.
The propellers will each have a diameter of 2.3 metres and an output of 1,500 kW. This propulsion set-up is expected to deliver a free running speed of 17.5 knots.
The propellers will also feature a DNV GL type-approved sealing system that will prevent water from entering the gearbox and prevent oil from escaping into the seawater.
To further enhance manoeuvrability, the new vessel will be equipped with one 315kW Schottel rim thruster type SRT 1000 in the bow. The rim thruster is a quiet, space- and weight-saving thruster that converts electric power directly into propulsion.
The SRT is also eco-friendly, as it operates without oil-based consumables. Instead, the bearings are lubricated by water.
Besides its main purpose as a fishery inspection vessel for the North Sea and Skagerrak area, the new vessel is designed to meet future inspection challenges, for example for the operation of large drones. It will also be able to provide service functions, such as emergency towing assistance, salvage operations, and surveys.
The inspection vessel is expected to be delivered by the summer of 2022 and will replace an existing vessel that has been in operation since 1987.
