Thanks to a customised modernisation by the Schottel after sales team, the operability of the Norwegian bulk carrier 'Pirholm' has been secured for the coming decades.

Schottel says that with comparatively low installation effort it could achieve several benefits, such as a significant speed improvement due to the new Schottel high-performance nozzle SDV45. This has reduced operating costs and fuel consumption significantly while further improving manoeuvrability, said to be particularly important during service on fish farms.

“Schottel has convinced us by responding to our needs and finding an individual, custom-fit solution for the vessel,” said Nils Tore Øpstad Melingen, General Manager, vessel owner Bio Feeder AS. “We are absolutely satisfied with the performance of the Schottel thrusters and would always decide the same way again. Moreover, Schottel as an OEM guarantees the availability of spare parts for the next decades.”

The company installed wo new Schottel azimuth thrusters type SRP 190 to replace the original Schottel SRP 330 Rudderpropellers. Because this solution could be integrated into the existing steel structure of the former propulsion system, no hull changes or major steel work were necessary. In addition, the work could be carried out by a local shipyard – reducing installation costs and shortening downtime.

The newly installed rudderpropellers are equipped with the SDV45 high-performance nozzles developed by Schottel. These generate more thrust and thus improve course-keeping ability and position stability many times over. Furthermore, the VarioDuct nozzles ensure that manoeuvrability and free running have improved. The new propulsion units do not only lead to a significant speed improvement and reduced fuel consumption, but also to considerably lower operating costs.

The Norwegian bulk carrier supplies fish feed to fish farms in the North Sea. Pirholm, built 1993 at Rosslauer Schiffswerft, measures 75m overall length and 11m width.
