RESULTS OF FULL SCALE MEASUREMENTS ABOARD CCGS LOUIS S. ST. LAURENT DURING EARLY ARCTIC PROBE 1977

The CCGS LOUIS S. ST. LAURENT was deployed in May 1977 to acquire information on the response of the ship to varied ice conditions and to assess the overall ice-transitting capabilities. Specifically ... 1. To obtain data on ship speed, ice thickness and type during ice transit and to analyze the data and correlate the speed to the ice characteristics and thrust. 2. To obtain thrust, and power data on the propulsion system during ice transit and to analyze the data and relate it to the data obtained in 1. 3. To measure accelerations and strains in the hull experienced during ice transit and from it, to estimate the loads imposed on the hull and relate this to the information obtained in 1 and 2. ... The tests undertaken fell into two categories, namely, those associated with the overall transit performance assessment and those associated with specific areas of icebreaking performance and ship ship response.
