The Trans-Alaska Pipeline System (TAPS) transports warm oil through a 48-inch diameter pipeline (mainline) 800 miles from Prudhoe Bay to Valdez, in Alaska. The system traverses continuous and discontinuous permafrost terrain and is supported…
Scope: This document specifies requirements and gives recommendations on the management of geohazard risks of pipeline during the design, construction and operational periods. This document shall apply to all operators and pipeline systems (existing…
The specifics of solid waste storage in permafrost were analyzed. The main types of impact of the waste on the natural environment and frozen soils were determined as mechanical, physicochemical, load, and thermal. The research allowed us to define…
Growing interest in liquefied natural gas (LNG) as a rocket fuel demands reliable prediction and an improved understanding of the changes in its composition arising from the preferential boil-off of lighter components during long duration storage.…
As an unconventional, clean energy resource, natural gas hydrate is abundant and widely distributed in the subsea and permafrost area. Since the 1990s, permafrost and ocean hydrate production tests have been conducted successively by Canada, the…
Since the success of recovering natural gas from hydrate-bearing reservoirs (HBRs) in Shenhu Area of the northern South China Sea in 2017, China has successfully produced natural gas from hydrates in permafrost and ocean environments. It certainly…
For foundation soils surrounding the crude oil pipeline in permafrost regions, the soil properties and the upper boundary conditions are stochastic because of complex geological processes and changeable atmospheric environment. The conventional…
In permafrost regions, long distance buried pipelines are widely used to transport oil and natural gas resources. However, pipeline problems occur frequently due to the complicated surrounding environment and transportation requirement of positive…
