The thesis is done in co-operation with DNV GL Harstad and Schlumberger. DNV GL has provided access to historical accidents data, by using technical documents. Schlumberger has provided technical information about well testing and hazards related to such an event, and an internal risk analysis document, which they use in their operations. This document is modified to suit, and account, for arctic hazards, and cold climate technologies. In addition, a probability calculation has been executed to show the methodology on how to use expert opinion in reliability challenges. The work on this analysis has been done in co-operation with Schlumberger, which resulted in a modified risk analysis where hazards, cold climate factors, influence on reliability & safety, mitigating and preventive measures is evaluated and included in the analysis for offshore operations. This was done to describe the event of implementing cold climate factors when calculating probability of an unwanted event to occur.
