Allied Shipbuilders (continued) The electrical generating system on the Cates 3 comprises two main generator sets, each a 95-kw, 1,800- rpm CAT model 3304 B. The sets are connected for nonparallel opera- tion, with automatic load transfer. One of the many features of this tug is the use of electric power for the main steering motors and haws- er winch. By use of a Mechtronics Series 59000 frequency controller, full variable speed control is ob- tained on these standard AC mo- tors. All crane and winch functions are controllable from within the wheelhouse, as well as from the fore- deck of the tug. The Cates 3 successfully com- pleted all trials and is now actively in service. As well as demonstrating the exceptional maneuverability and control associated with the twin Z-drive configuration, the vessel re- corded sustained bollard pulls of 34,015 kg ahead, and 30,720 kg astern, and a free running speed of 11 knots.

The company got orders for equipment for 103 tankers. In addi- tion, a large amount of orders for level gaging equipment for refiner- ies and process industries was re- ceived. Korea was Saab Marine's largest market in 1990, followed by Den- mark, Italy, Singapore and Japan. Many of the orders were for Scandi- navian shipowners. The largest sin- gle order during the year was equip- ment for 15 tankers for the Danish shipowner Terkol. Eighty percent of Saab Marine's manufacturing capacity has now been booked for 1991. Saab Marine Electronics is a market leader for level gaging equipment onboard tankers. The system, Saab TankRadar, utilizes a measurement method based on ra- dar technology by which an accura- cy of ±2 mm up to a depth of 60 meters can be achieved. Saab Ma- rine is a member of the Saab-Scania Combitech Group, a company group dedicated to the development of high-tech products for new applica- tions.

Correction The downsizing of the Keystone Canyon at the Portland Ship Repair Yard last fall was accomplished solely by Northwest Marine, Inc., and not by a union of PSRY's three contractors as was reported in the January issue. Northwest Marine, Inc. removed 50 feet and 40,000 deadweight tons of capacity from the Keystone Canyon to enable her to trade in Puget Sound and San Pedro Bay. 14 Maritime Reporter/Engineering News
