| Summary: | Bibliography: p. 243-252 ... : Structures utilized for the exploration and development of hydrocarbon resources in ice-covered water are by nature expensive and complex. Molikpaq, Gulfs Mobile Arctic Caisson, is one of such structures which was used successfully to drill in the Canadian Beaufort Sea. During one deployment of the caisson, it was subjected to ice interaction events resulting in critically large dynamic loads. Various models have recently been developed to describe the interaction between moving ice sheets and structures. While these models show considerable promise to adequately describe the problem, they do not provide a full description of the process nor have they yet met the challenge of modelling actual interactions. The main objective of this study is to develop a detailed non-linear finite element model which is capable of predicting the dynamic loading on offshore structures due to the movement of ice against them, and to study the behaviour of such structures under these dynamic effects. Molikpaq is taken as a ... |
