Permafrost thaw induced settlement is a major concern for pipeline design and operation in the Arctic region. For a buried warm pipeline in permafrost, heat losses can thaw the frozen water in the surrounding soil and create a thaw bulb around the pi

International audience; A multi-material local approach to creep damage was applied to a ferritic-martensitic ASME Grade 91 steel welded joint at 625 °C. Focus was made on the detailed analysis of the most sensitive area of the weld i.e. the intercr

Thaw subsidence and frost heave are two different hazards to pipelines in arctic regions. The former is due to the thawing of permafrost induced by a warm pipeline, while the latter is resulted from a cold buried pipeline that causes ice lens growth

High temperature creep flow and damage properties of 9Cr1MoNbV steel and weldment are investigated in the present study. First, an experimental database is built to compare both creep flow and damage properties of the base metal and the weldment. Met

Composite repair systems are used for many years to restore locally the pipe strength where it has been affected by damage such as wall thickness reduction due to corrosion, dent, lamination or cracks. Composite repair systems are commonly qualified,

Frost heave is a common phenomenon in the Arctic, where soil expands in the direction of heat loss due to ice lens growth upon freezing. It also occurs if a refrigerated structure is buried in unfrozen frost heave-susceptible soil, and thus special c
