... area requires the consideration of design conditions that do not apply elsewhere, such as ice gouging, frost heave and permafrost. Advanced numerical analysis is apt to play an important role in addressing these challenges and to bridge the technology gaps that still exist in order to enable optimized...

... 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...

Paper Number: OTC-24603-MS
... Abstract Ice gouging or scour may damage structures buried in seabeds, hence research on this subject is important. Numerical modelling is one of the most flexible and least costly methods of studying ice gouging. Previously, information on existing numerical models and their results...

... systems have been used, which are a cost effective, safe and reliable mode of hydrocarbon transport to shore. Ice gouging is one of the key design issues that affect engineering considerations with respect to strain based design, target burial depth requirements, cost, and safety. It is generally...
