ARCTEC Canada Limited

Opens Testing Facility

And Ice Towing Basin

Transport Minister Otto Lang "piloted" an icebreaker through a frozen channel recently to of- ficially open ARCTEC Canada

Limited's new Canadian head- quarters.

It was a simulated, yet ex- tremely realistic "maiden voyage" in ARCTEC's new ice tank, a sophisticated testing facility to determine the effects of ice on marine structures and vessels.

The "Cold Regions Marine Re- search and Engineering Labora- tory" is the first privately owned laboratory in Canada devoted ex- clusively to ice technology, and one of only four in the world.

The new 14,000-square-foot fa- cility features a synthetic ice towing basin measuring 60 by 20 feet, as well as a saline ice towing basin 100 feet long and 16 feet wide. The facility is also equipped with scientific cold rooms and a hydraulics laboratory.

ARCTEC Canada president

Roderick Y. Edwards Jr. says his firm has developed a system of creating synthetic ice which "is as good as the real thing." The invention is the brainchild of Dr.

Bernard Michel of Laval Univer- sity, one of ARCTEC's founders.

The ARCTEC process uses a chemical material that models the full-scale properties of ice in model scale. "The process involves the mixture of chemical com- pounds that are a trade secret," said Mr. Edwards.

The synthetic ice concept al- ready has a proven track record.

It has been used to test the ef- fects of ice on offshore structures for several major oil companies.

Saline ice is frozen from salt water by an ARCTEC-patented cryogenic freezing process. This fast freezing produces a control- lable crystal structure that allows scaling the strength of the ice sheet in similitude with its thick- ness. This technique will be a first for Canada.

The opening of ARCTEC's Ot- tawa facility completes its con- solidation from three locations.

Activity will now be centered in the national capital. "Ottawa is a growing center of Canadian technological research and devel- opment. Our work involves a great deal of liaison with the National

Research Council and the Minis- try of Transport. It will also al- low us to better serve our gov- ernment clients," concluded Mr.

Edwards.

The new ice tank is located at the headquarters of ARCTEC

Canada Limited, 311 Legget

Drive, Kanata, Ontario K2K 1Z8.

The LcTourncau Difference:

More Lift. All Electric. All LeTourneau.

Marathon LeTourneau-developed heavy lift cranes serve the offshore industry, marine construction and dockside opera- tions with proven superiority of more than seven million hours in all kinds of hostile environments. marathon

When it comes to long-radius lifting capacity, no other manufacturer quite compares with LeTourneau.

Take our unique PCM-120 AS vari- able radius crane. This rugged, de- pendable, proven workhorse lifts 50-tons off a 120' boom. Provides 1200 Ft. tons of lift. Plus you can rely on a compact machinery house for a space-saving swing.

Optional boom lengths from 60' (18288mm) to 120' (36576mm).

Construction to DNV, ABS and API specifications and the assurance that comes only with the name

LeTourneau.
