The principal rationale for conducting this study as stated in the contract is to assess if a double walled design provides the same or a greater degree of engineering integrity and environmental robustness as compared to a thicker walled single pipe design for an arctic offshore application and to appraise the economics of one selection over the other relative to the potential risks (real and/or perceived) associated with either application. The study included an appraisal of the economics of each pipeline system including life cycle costs, and an analysis of risks within the framework of statistics for performance of offshore pipelines. The risk statistics are derived from work by other experts for other offshore regions in the world. |
