Abstract
Maximum effective ice pressures of 0.8 to 1.1 MPa were measured on a 90m wide caisson in the Beaufort Sea for 0.7m thick sea ice in mid February. In April, when the ice was warmer, maximum effective pressures of 0.5 to 0.8 MPa were recorded for 0.6m thick sea ice. Model test results from 30mm thick EG/AD ice of 60 kPa flexural strength gave maximum effective ice pressures of 40 kPa which scale to 0.9 MPa in full scale, a very good comparison.
