Pipeline Engineering for Freezing Ground and Permafrost

Petroleum and pipeline companies are presently preparing data sets for pipeline frost heave and frost bulb growth predictions. At the same time, government departments and regulatory bodies are charged with filling information gaps pertaining to the long-term performance of a gas pipeline in permafrost-affected terrain. Closing this knowledge gap becomes even more critical and timely given the concern about changing permafrost environments due to climate change.

Permafrost Environmental Consulting a company devoted to cold regions research is pleased to announce the immediate release of its “Pipelines in Permafrost and Freezing Ground Engineering Resource Library and Database Indexes”, Program Modules and Database Modules. The fourteen-volume book set enable engineers and geo-scientists to fill these information gaps and to examine the interdependence between buried pipelines and the behavior of freezing soils and permafrost-affected soils, and to develop, test, calibrate, and verify numerical models of frost heave and thermodynamic processes.

Developed from the six databases produced during 12 years of full-scale physical modeling of pipelines in freezing ground and permafrost, the Library, Program Modules, and Database Modules allow the user to evaluate aspects of frost heave attributed to differences in the properties of the soil, differences in the thermal transition between perennially frozen and seasonally frozen soil, and different hydrological conditions.

Models developed using our Program Modules are used to Predict

• Soil strain and soil creep
• Frost heave and frost bulb growth
• Thaw consolidation and pipeline relaxation
• Pressure in freezing soils and permafrost-affected soils
• Bending stresses in buried pipelines
• Uplift resistance of pipelines in permafrost
• Hydrological properties of freezing soils and permafrost-affected soils
