Calculation of Arrival Intensity of Ridges Accounting for the Relative Angle Between Ridge Direction and Ice Drift Direction Available to Purchase

The purpose of the study is to investigate the effect of the relative angle between ice ridges and sea ice drift directions on the arrival rate of ridges. The arrival rate is of importance both for estimating the load conditions at a site and for possible ice management connected to the operation. If the number of encounters increases, the probability of encounter of an extreme ice feature and load increases. A Monte Carlo simulation has been made to calculate the ridge arrival intensity for input formulated as distributions. In probabilistic calculations of design loads today the average arrival intensity is used and the ridge directions are assumed to be uniformly distributed. The implications of accounting for the varying arrival intensity due to the distribution of the relative direction of ridges to velocity on the design load are discussed.
