Designing for performability: An icing risk index for Arctic offshore

• This paper will discuss the effects of different types of ice accretion on the performability of Arctic offshore production facilities.
• To quantify the effects of ice accretion on the performability of offshore production facilities, an icing risk index is developed.
• The application of icing risk index is shown by means of a case study.

Ice accretion affects the performability of offshore production facilities in various ways, including repair time and failure rate. It can increase power losses, life cycle costs, and safety hazards. There are few studies and limited systematically collected information about the impact of ice accretion on performability and its attributes (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 performability of offshore production facilities, an icing risk index is developed; its application is then shown by means of a case study.
