Recent Order For Two Schottel Thruster Units A First In U.S. Market
An order received recently by Schottel of America, Inc. of Miami, Fla., for its new SPJ-32 Pump Jet thruster units to be installed in two 92-foot line-handling tugs, marks the introduction of the 360-degree steerable, centrifugal-pump water thruster to the American market, and represents the first application of this design concept in the U.S. Under construction at Moss Point Marine in Escatawpa, Miss., the 2,350-bhp Heimo Tide and Ade Tide will be operated by Tidewater Marine Service in West Africa, and will utilize the Pump Jets as bow maneuvering aids.
The new water jet product line, originally developed by Schottel Werft of Spay, West Germany, in conjunction with NATO Army Engineers for their "Bridging Equipment of the 80s" program, was designed as either a main propulsion unit or maneuvering aid for extremely shallow-draft vessels.
Schottel, a world leader in the field of steerable propulsion equipment, is very experienced in the design of water jet thrusters. More than 250 Schottel cone and bow jet units are in service in vessels operating on Europe's inland waterways system, where draft restrictions make conventional tunnel thrusters impractical due to cavitation and low efficiency.
The Tidewater Pump Jet units will be powered by hydraulic motors developing 120 hp at 2,800 rpm, although electric or diesel prime movers can be utilized in other applications as required.
