Foss To Order New Tugs With Voith Schneider Systems Foss Launch & Tug Co., Seattle, Wash., announced it has received approval from the Dillingham Corporation, its parent company, to purchase three new, revolution- ary Tractor Tugs, with an option for a fourth, as additions to its West Coast fleet. The new tugs will incorporate the Voith Schneider cycloidal propeller sys- tem developed in Germany. Bruce J. Robeson, president of Foss, said in making the an- nouncement: "The Tractor Tug Concept, with the Voith Schneid- er propulsion system, was selected after an intensive evaluation process in order to satisfy the unique operating requirements of ship assist, harbor shifting and ship escort on Puget Sound. This system was specifically designed for ship handling work, and the well-tested concept allows the tug operator to apply thrust in any di- rection and force magnitude through 360 degrees, a decided advantage while assisting and maneuvering large ships." The cycloidal propeller is a vertically oriented, controllable pitch propulsion system located approximately one-third of the distance aft of the bow. This fea- ture significantly reduces the risk of capsizing the tug during hand- ling operations, permits the tug to get alongside a ship at higher speeds, and enables a tug in a dy- namic ship assist situation to ex- ert forces greater than its bollard pull on the vessel it is assisting. The new twin-engine Tractor Tugs will be rated at 3,000 hp and 4,000 hp. The two 3,000-hp tugs will have a length of 100 feet, a beam of 36 feet, a draft of 16 feet, and will be powered by two GM- EMD 12-cylinder E-6 diesel en- gines. The two 4,000-hp tugs will have a length of 160 feet, a beam of 38 feet, a draft of 17 feet, and Skagit Offers 130-Page Catalog On Full Line Of Offshore Deck Machinery A ring-bound, hard-cover cata- log containing 130 removable pages and data sheets is being of- fered by the Skagit Corporation. Skagit Division of Continental Emsco Company, Sedro-Woolley, Wash., specializes in the design, development, and manufacture of a wide variety of heavy-duty equipment to meet the specific needs of its marine/offshore cus- tomers. Over the years, a standard line of equipment has evolved to meet most requirements of drilling and construction vessels. This big ring-bound catalog presents Skag- it's standard line of equipment for offshore drilling and construction applications. All models shown have been designed, constructed, and proven. As a result, they may be purchased at a cost substantial- ly lower than units requiring new engineering, tooling, pattern cut- ting, spare parts documenting, and writing efforts. However, the Skagit line is flexible. If a customer has require- ments over and above the specific will be powered by two GM-EMD 16-cylinder E-6 diesel engines. The conceptual design of the new Foss Tractor Tugs was devel- oped by Don Hogue, manager of administration-Ocean Division, and Jim Cole, assistant manager- Foss Shipyard. L.R. Glosten & Associates are the naval archi- tects for the tugs. A builder has yet to be named. Foss expects to take delivery of the tugs in 1982. equipment presented in this cata- log, Skagit's engineering and marketing staff will work closely with him to help solve specific equipment needs. Skagit's list of offshore customers includes drill- ing and supply vessel operators worldwide. The catalog is divided into 12 sections, each giving full technical specifications and applications, and illustrating each unit with schematic drawings, diagrams, and photographs. The machinery described includes: mooring equip- ment; windlasses, winches, and combination units for drilling ves- sel mooring systems; winches for construction vessel mooring sys- tems ; towing winches; capstans; hoists; fairleads for mooring systems; special application sheaves for mooring systems; jackup winches; and cranes. Features of Skagit offshore cranes, which meet the require- ments of the American Bureau of Shipping and the American Petro- leum Institute, include simplicity of operation, serviceability, high line speed, tubular lattice boom, diesel or electric power, piston hydraulics, independent functions, and excellent visibility. In addition to the Sedro-Wool- ley headquarters, Skagit main- tains offices in Houston and Paris.
