NEW SHALLOW-WATER THRUSTER EXTENDS PUMP JET POWER RANGE

Wednesday, February 20, 2019 

Schottel, the manufacturer of marine propulsion systems, is launching its new Pump Jet SPJ 30 a shallow-water thruster that is suitable for a wide range of different vessel types, such as passenger vessels, ferries, work vessels and freighters.

Available in the power class up to 150 kW, the azimuth thruster is characterised by optimal efficiency and is said to give the vessel maximum manoeuvrability. The thrust and propulsion efficiency have been further enhanced, by means of CFD optimisations.

Schottel says that the SPJ 30 is a highly efficient azimuth thruster, suitable for both newbuildings and for modernisations. Due to the compact design, space-saving installation is possible with minimal displacement loss. The thruster is highly versatile: the above-water gearboxes are available as Z and L variants, and diesel engines, electric or hydraulic motors can be used as power sources.

Since the Pump Jet is installed flush with the hull of the vessel, the vessel’s resistance is not increased and the risk of collisions with flotsam is greatly reduced. Further protection against damage is provided by the protective grille on the inlet. The SPJ is thus capable of operation in extremely shallow waters – even in the event of grounding, the risk of damage is considerably reduced. The thruster is optionally available with elastic mounting, which further reduces noise levels and vibrations.

Schottel says the Pump Jet has proved its worth over many years as a reliable manoeuvring system, take-home device and main propulsion unit on a wide range of craft. Its power range is from 50 to 3500 kW. Supplying full thrust at a minimum immersion of 150 to 750 mm (depending on the specific model), it can be used on vessels with very shallow draught. The new SPJ 30 will be available from the end of the year.
