Infrastructure Adaptions to Changing Permafrost Conditions—Three Case Studies along the Trans Alaska Pipeline System
The Trans Alaska Pipeline System (TAPS) was constructed in the 1970s to transport warm crude oil from Prudhoe Bay to Valdez over a distance of about 1,300 kilometers. TAPS traverses three major mountain ranges as well as continuous and discontinuous permafrost terrain. TAPS design was a major advancement in cold regions engineering and the system has outperformed its design life. Changing thermal conditions at isolated permafrost sites along TAPS have required increased maintenance and adaptations to maintain TAPS integrity and resilience for the next generation of operation. This paper presents three cases along the TAPS where the original design was no longer performing as intended due to changed subsurface thermal conditions and where Alyeska Pipeline Service Company implemented mitigation to ensure safe pipeline operation for many more years.
