ANOTHER TUG THRUSTER REFERENCE FOR SCHOTTEL

Thursday, February 27, 2020 

'Bolko', the first of six multi-role ASD tugs built by Remontowa Shipyard in Poland has recently been delivered to the Polish Navy, to be followed by a further five; all six vessels being equipped with Schottel Rudderpropellers.

Bolko and her sisters, Gniewko, Mieszko, Semko, Leszko and Przemko, are scheduled for delivery in the near future and will be used for military and logistic operations support at sea and in ports, as well as for technical evacuations, personnel transfers, search and rescue operations and oil spill recovery.

The propulsion system of the Navy tugs consists of two ice-classed Schottel Rudderpropellers type SRP 360 with 2.0m fixed pitch propellers. Each thruster is driven by an MTU 12V 4000 engine delivering a power of 1,19 kW, enabling the tugs to achieve bollard pull of up to 35t and free-running speed of 12 knots. Thanks to FSIC IA ice class reinforcement, these vessels can be deployed in the Baltic Sea at any time of the year.

According to Schottel, operation in regions where ice is present places special demands on propulsion systems, and the company has built up a vast amount of experience in this field. Today, the German manufacturer offers a series of ice-class-strengthened azimuth thrusters up to Finnish-Swedish ice class IA Super.
