Icing and performance of offshore production facilities in cold climate region

Ice accretion affect performability of offshore production facilities in various ways, including repair time and failure rate. Moreover, it can increase the power losses, life cycle costs and safety hazards. There are few studies and systematically collected information about the impact of ice accretion on performability and its concepts (reliability, maintainability, quality, safety and sustainability) for Arctic offshore production facilities. This paper will discuss the effects of different types of ice accretion on the performability of Arctic offshore production facilities. Then, to quantify their effect on the production facilities´ performability, an icing performability index is developed.
