Abstract: Realistic estimation of the effects of ice floe impact is desirable for the design of certain sub-arctic offshore structures. The results of a preliminary study on dynamic ice-structure impact are described, for a large ice floe striking a tubular steel platform. The ice is modeled taking into account strain rate effects. A simplified model is used for the platform structure, to reduce computational effort. Comparisons are made of the results obtained from both static and dynamic analyses. It is concluded that the static and dynamic results can generally not be correlated, and hence that dynamic analysis is desirable.
