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 En- gineers for their "Bridging Equip- ment of the 80s" program, was de- signed as either a main propulsion unit or maneuvering aid for ex- tremely shallow-draft vessels. Schottel, a world leader in the field of steerable propulsion equip- ment, is very experienced in the design of water jet thrusters. More than 250 Schottel cone and bow jet units are in service in vessels operat- ing 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 ap- plications as required.

They are available in a variety of shapes, including manifold and reducing tees, unions and ATW to Swagelok connectors.

Work will be performed in Anaheim, and is expected to be completed by September 30, 1985. Contract funds would not have ex- pired at the end of the current fiscal year. The Naval Sea Systems Com- mand, Washington, D.C., is the con- tracting activity (N00024-85-C- 4000). Weld Fittings Available From Cajon Company —Literature Available The Cajon Co., of Macedonia, Ohio, now has available tube butt weld and socket weld fittings for use in systems fabricated with automat- ic orbital head welding equipment or done manually. The fitting series, designated ATW and ASW, are extremely com- pact. Both series are made of 316L stainless steel for maximum protec- tion against stress corrosion caused by high welding temperatures. Ex- cept for the Swagelok to ATW con- nectors, the fittings are made from fully traceable materials. The ATW has an enlarged end which aligns the tubing and speeds welding setup. ASW fittings feature a thin wall which is useful for socket weld applications using automatic or manual equipment. Both fittings measure .750 inches from the shoul- der to the welding point, allowing for use with most automatic weld- ers. January 1, 1985 Mr^ m - The Fast Cats From Down Under Are Now Being Built Over Here. Economics, not adjectives, sell vessels. Even though this Nichols Brothers' 72-foot catamaran offers commodious capacity ... stimulating speed ... operational simplicity ... rough water safety ... striking appointments ... a rugged work platform ... operators may be more interested in some stark figures. This catamaran carries 210 passengers, at 26 fuel thrifty knots, with a pair of 800 hp engines, at a decidedly pedestrian construction price. Behind the design lies a remarkable story. International Catamarans of Australia performed a rare feat of synergy in the design of a catamaran ferry for Tasmank. So successful .vyas this design, a growing number of descertdents" are in service arounathe world as ferries, tour boats, offshore and utility boats, and patrol boats. Production has been licensed now, North America with Nichols Brpthers as lead yard. Designs range to 120 di more feet, 30-knot speed, and 5€C more passengers. Initial Nichols' cafcarafarans include the Klondike for Alaskan service, and the Alderbrook on Puget Sound. Like others of the family of ^^^ catamarans from Down i• •' j *• TtV Under, Nichols' ——- boats include unique design features: Water slicing hulls ... A cabin to hull mounting dampens * 1 t ft sound and ' ) " vibration—" r J LM ...A lifting I •H rudder that -tesM (H reduces drag .. . and more.
