... such as strudel scour, permafrost thaw settlement, and ice gouging. These evolving design methodologies are comprised in INTECSEA's in-house suite of Arctic Tools and pipeline design standards. Focus is also placed on the importance of appropriate environmental and geotechnical data collection, the use of limit...

... of the soils. The results were used to characterize the geologic setting and permafrost conditions, estimate thaw settlement of the gravel fill and underlying permafrost, compressibility and strength of seabed sediments, island slope stability, and shear resistance to global ice forces. The island site...

... information when things have gone wrong. Without monitoring, the condition would continue to degrade the pipeline integrity until failure. Due to Arctic pipeline design and operational challenges, like ice gouging, strudel scour, upheaval buckling, frost heave and permafrost thaw settlement, along...

... of the thaw settlement-related properties of the test pipeline continued until the middle of April 2005. The following results were presented at the 2nd ATC: 1) As the frost-bulb around the pipeline in talik section formed, the test pipeline in the talik section moved upward, resulting in bending...

... mechanisms for biasing gouge statistics. Other challenges that must be considered include strudel and hydrodrnamic scour, thaw settlement and frost heave, and upheaval buckling. These considerations may also influence burial depth requirements. pipeline design thaw settlement pipeline route ice...
