maneuverability and power that provides substantially increased economy and safety for the new tug- boat. This advanced tractor tug, though common in most European and Far East ports, is said to be the first placed in service on the U.S.

East Coast. She is now performing ship docking service in the Port of

Jacksonville, Fla.

The Schottel system transforms engine output into optimum thrust by use of specially designed gears and a proportional propeller. Full thrust is provided to move the tug almost instantly in any direction by rotating the lower gearbox, without power loss, and with maximum ma- neuvering capability at full power ahead, astern, and laterally. Turn- ing circles and stopping distance at full power can be executed in ap- proximately one tug length.

Power is transmitted by the Rud- derpropeller through silent-run- ning, spiral-bevel gears; packing seals are fitted throughout. Fixed or controllable-pitch propellers are of the push-type, designed to suit the individual vessel. For tugboat pro- pulsion, most of the units are fitted with nozzles to increase thrust.

Schottel Rudderpropellers are available in a power range from 27 to 6,000 bhp.

Other Schottel products, the

Cone-Jet and Pump-Jet, have been specially developed as steerable pro- pulsion units and maneuvering aids for shallow-draft vessels. Such ves- sels include river ferries, floating plants, pontoons, and amphibious craft. The jet units are integrated into the hull and fully protects against damage by grounding. The unit produces a jet stream for op- timum thrust that is steerable through 360 degrees, thus giving propulsion in any direction. Over the years Schottel jet units have proved themselves, under the most adverse conditions, all over the world.

SIEMENS

Circle 2 on Reader Service Card

Siemens AG of Hamburg has been a supplier of a wide range of electrical and electronic equipment and services to the marine industry for more than a century. The Ger- man company is represented in the

U.S. by Siemens Energy and Auto- mation, Inc. of South Plainfield,

N.J.

One of the most recent orders for the U.S. market was from Pennsyl- vania Shipbuilding for the power takeoff generating systems for the three fleet oilers (T-AO-191, 192, and 194) that the Chester, Pa., ship- yard is building for the U.S. Navy.

Each shipset consists of two 2,500- kw, constant-frequency generators driven by PTOs off the main engine reduction gear. The function of each system can be reversed, allowing the

PTO generators to serve as motors for emergency "take-home" propul- sion.

Another big order was from Bay

Shipbuilding Corporation in Stur- geon Bay, Wise., to supply the ma- jority of the automation equipment,

September, 1986 including the consoles, for the three containerships under construction for Sea-Land Service. The first of these ships will be delivered later this year, with the other two follow- ing in 1987. Another Sea-Land order was an on-board retrofit project in which Siemens upgraded four exist- ing containerships to operate with unmanned engine rooms (UMS).

Another recent order, via MaK

Diesel, was for supplying the alter- nators for the two T-AGS surveying ships under contract to Bethlehem

Steel's Sparrows Point yard for the

U.S. Navy.

Siemens also supplied the engine control consoles, complete with an alarm and monitoring system laid out for 340 inputs, for the 12 Econo- ships built for United States Lines by Daewoo Shipbuilding. These ves- sels, the largest containerships in the world, are now operating in

USL's round-the-world service.

Siemens also provided a constant- frequency shaft generator of 2,000 kw for each of the six containerships being built in Japan for Lykes Bros.
