Discontinuous Galerkin method for simulation of ice flow impact on vertical cylinder offshore structure

This paper describes an approach to numerical simulation of ice field impact on cylinder vertical offshore structure, as well as detailed review of related complications. The paper presents 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. Presented numerical results demonstrate applicability of ice model and implemented software to industrial problems of safety of oil and gas platforms on the Arctic shelf.
