FULL SCALE TESTING IN ICE OF THREE ICEBREAKERS

In 1967 the Canadian Coast Guard commenced to use modeling techniques in the development and planning of new icebreakers. It was apparent that model testing and production techniques for full scale performance in ice, unlike open water techniques, was seriously lacking in actual full scale performance data for confirmation and correlation. Accordingly the Coast Guard undertook some full scale testing programs as time and expediency permitted. Three such testing programs are reported on in this paper, starting with CCGS WOLFE in 1969, LOUIS ST-LAURENT in 1970 and LABRADOR in 1973. Up to now the results have not been published. The results of full scale measured tests in ice are still woefully lacking and it is the purpose of this paper to help fill the gap by publishing these results. Having occurred over a span of several years and taken place for different purposes in widely different conditions, the test techniques and formats are not the same for the three sets of tests. The results presented are "raw", as developed at the time of the tests and have not been reworked.
