Record #109975:

Thaw-subsidence effects on offshore pipelines / J.F. Nixon.

Title: Thaw-subsidence effects on offshore pipelines / J.F. Nixon.
Author(s): Nixon, J. F.
Nixon, Derick.
Date: 1991.
In: Journal of Cold Regions Engineering. (1991.), Vol. 5(1) (1991)
Abstract: Reviews permafrost conditions from deeper water conditions offshore through shallower water nearshore to onshore colder conditions. Shows that buried offshore pipe line appears capable of accommodating up to 1 m or more of thaw settlement for range of soil properties considered, providing that settling permafrost layer is located at least 3 to 4 m below pipe base. If settling permafrost layer is closer to pipe base, some form of mitigation, such as insulation, might be required.
Notes:

Journal of Cold Regions Engineering. Vol. 5(1) :28-39 (1991).
