Floating Factory Completes

Nine-Day, 2,500-Mile

Voyage To Canadian Arctic

A factory barge as big as a football field recently completed a 2,500-mile voyage from the St.

Lawrence River to a small island in the Canadian Arctic.

It arrived nine days ahead of schedule — at Little Cornwallis

Island, 600 miles above the Arc- tic Circle, to help exploit the most northerly base metal mine in the world.

The $40-million floating fac- tory was drawn by tugboats through iceberg-infested waters during the short "Arctic ship- ping window" which sometimes lasts no more than six weeks.

The huge factory barge, called the Arvik 11, left Three Rivers, near Montreal, on July 24. It will be part of the Polaris mine op- erated by Vancouver-based Com- inco Ltd., which is slated to start lead and zinc concentrate produc- tion early next year.

While the barge base was built by Davie Shipbuilding, Lauzon,

Quebec, Comstock and Dominion

Bridge constructed the ore proc- essing plant onboard the vessel.

Bechtel Canada is responsible for the surface facilities for the project. 3.

Navigation Computer

System From Trimble

Trimble Navigation recently introduced a powerful new navi- gation computer system, CS-1 that incorporates graphics dis- play and printout capability. The

CS-1 can be used for piloting, position monitoring, trip logging, trip planning, and a variety of special computations including true wind, set and drift, distance, course, time and speed made good to the next waypoint.

The CS-1 stores 500 waypoints, 20 trip plans, and 500 obstruc- tions/hazards. The unit provides a variety of real time visual graphic displays of ship's posi- tion relative to course and haz- ards. Audio alarms for cross track error, distance to hazards, and waypoints are user pro- grammable.

The CS-1 stores magnetic vari- ation worldwide and automatic- ally presents magnetic headings for specific locations. Permanent trip records can be printed and/ or stored on magnetic tape auto- matically at user-selected inter- vals or on command.

The CS-1 consists of a Trimble

Model 10A High Accuracy Loran-

C, a Hewlett Packard Model 85 computer, and Trimble-designed software. Users may provide their own HP-85 computer.
