The proposed methodology for selecting optimal design solutions for oil pipeline laying in the permafrost zone is based on probabilistic approach to predicting thermal and mechanical interactions between a buried pipeline and frozen soils. It allows choosing the optimal pipeline routing, laying techniques and design parameters, in keeping with the principle of minimum initial investment and loss contingency.
