SIPW03 - Ice-structure interaction

Co-author – Prof. Igor B. Petrov

This talk describes an approach to numerical simulation of ice field impact on cylinder vertical offshore structure, as well as review of related complications.
Also it provides information on ice rheology, a continuous mechanics model used, which makes it possible to achieve a balance between accuracy and amount of computational resources needed. The description of the numerical method, and also some features of the simulation and techniques, which allow to overcome a number of difficulties associated with the resource-intensive calculations, are given. Typical destruction patterns of the ice fields and pressure distributions on structures are discussed.
