To learn more on ice crushing phenomena against a compliant stiffened plate structure, near full-scale ice crushing tests were conducted in Aker Arctic test basin with a 1:3 scaled model. The dimensions of the to be crushed ice sheet and the stiffened plate were chosen to present a full size ship or offshore structure steel plating which are designed to withstand the crushing loads of 60 cm thick level ice. A major difference to the crushing tests published earlier in literature was that the com...

Subzero temperatures at high latitudes typically restrict shipping but facilitate ground transportation. A study quantifies the impacts of climate change on Arctic transportation by mid-century and finds that all eight Arctic states will probably suffer steep declines in inland transport, but will reap the benefits of faster sea travel.

Abstract The physical processes involved in the interaction of ice masses with offshore structures are described. For design purposes, two pressure-area relationships have been deduced, which take into account the randomness of data. The first is for local pressures, using ranked data from ship rams, resulting in a power-law decrease (≃−0.7) of pressure with design area. A second (global) pressure-area relationship with random parameters has been developed, also based on data from ship rams, wit...

Extensive work in recent years has been carried out on the calculation of global ice loads on a probabilistic basis. An analysis method is presented for local ice pressures, which yields values of pressure for specific values of exceedance probability. In developing this method, particular attention has been paid to problems of exposure (length, position and number of impacts), as well as the area of exposure (area within area versus nominal contact area). The solution has been formulated for a ...

Abstract In the structural design of the Polar Class ships, glancing impact with ice has been considered as the governing load scenario for dimensioning the bow structure. At present, non-linear transient dynamic analysis has been reckoned as a fundamental requirement in the assessment of the structural strength of ships with higher ice classes. Under such requirement, understanding of the dynamic characteristics of the ship-ice impact load appears significant importance. The present study aims ...
