RESULTS OF FULL-SCALE ICE IMPACT LOAD STUDIES ABOARD C.C.G.S. NORMAN MCLEOD ROGERS

In order to develop new safety standards and regulations for the movement of ships in ice-infested waters, the Canadian Department of Transport initiated in 1974 an overall study of ice problems affecting the operation of ships in the St Lawrence System. The study included the assessment of ice conditions in critical reaches, the development of an analytical predictive model, full scale impact load measurements and physical modeling of ice impact loading. The mathematical model was completed in April 1974. The present paper describes the instrumentation and test procedures used during a program of full-scale measurements of impact loads carried out in the course of normal icebreaking operations by the C.C.G.S. Norman McLeod Rogers. The results of measurements of impact loads, ship speed and mean ice thickness are summarized for a total of 84 runs. It is concluded that the instrumentation gives realistic results but that further refinement of the mathematical model will be necessary. Order from BSRA as No. 49,770.
