The harsh climate conditions and vulnerability of the Arctic wilderness can both heighten the risk related to HSE (human, safety and environment) and limit the effectiveness of any activities which are carried out to control such risks. To manage and control these risks, it is vital to reduce the probability of failure of critical components in the corresponding industrial setting. In order to accomplish the aforementioned, it is essential to have an accurate prediction of failure characteristics (e.g. failure modes, time to failure and failure mechanisms) and the consequence of failure which can be taken into consideration during the design phase. It is possible to gather such information by means of an effective risk and dependability analysis.

However, in practice, conducting a dependability and risk analysis is a challenging process for an industrial setting, such as that which is functioning in the Norwegian Arctic. This is mainly due to the lack of historical data about possible activities which are unique to the region. Hence, it is paramount to develop a methodology to facilitate the analysis, using the available data experience and technological solutions which can be retrieved from similar or more challenging situations as a reference to improve the robustness of the current design. This paper reviews the main technical and technological challenges of the operations in the Arctic region. Then, it provides a methodology to take risk and dependability analysis for Arctic conditions into consideration in the design phase. This methodology is demonstrated by a case study for design in the Barents Sea based on the available data collected in the North Sea and the Norwegian Sea.
