A Norwegian bulk carrier owned by Bio Feeder will soon be able to take on new assignments thanks to a customised upgrade by the Schottel Modernisation and Conversion Team.

Two retractable rudder propellers type SRP 130 R at 300 kW each and two transverse thrusters type STT 1 (450 kW each) will be installed on Kryssholm in addition to the existing main propulsion system. This will maximise its manoeuvrability capabilities and position stability, in turn extending the vessel’s operation profiles so that it can be used for a wider variety of tasks.

“Schottel, with whom we have a long-standing and consistently good partnership, has again convinced us by finding an individual, custom-fit solution for the vessel,” said Nils Tore Øpstad Melingen, general manager of Bio Feeder. “We are absolutely satisfied with the performance of the Schottel thrusters in our other vessel and thus decided the same way again.”

To reduce the environmental impact, the Schottel propulsion units will be driven by electric motors powered by a hybrid grid of batteries and generators. Kryssholm, built in 2011, measures an overall length of 89.9 metres and a width of 13.6 metres and is considered the largest fish feed vessel in the world with a capacity of more than 3,000 tonnes. Kryssholm will be operating for Biomar six months a year; the rest of the time it is chartered to Wagle Chartering for transporting general cargo.

The vessel is the first in the world that is fit for such a hybrid operation and is scheduled for completion in the first quarter of 2021.
