... 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...

... 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...

... Abstract Subsea pipelines located in ice environments need to be protected from potential ice gouging (also known as ice scouring) created when a moving ice keel interacts with the seabed. The integrity and operability of the pipeline can be affected by direct contact between the ice keel...

... Abstract The objective of this paper is to demonstrate how modelling can be used to account for the inherent correlations while assessing the pipe response to ice gouging – and thus narrow down the uncertainties associated with the pipeline design process. A custom-developed numerical model...

... 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...

Statistical distributions andprobabilistic assessments of ice gouge records can be used to predict designextreme gouge depths which can then be used to determine pipeline burial depthsrequired for protection against ice keels. The Northstar subsea...

.... In the arctic regions, subsea pipelines must be designed to survive extremely harsh conditions such as low temperatures, thermally induced fatigue, and high stresses from ice gouging. In a study supported by a recent Ice Pipe JIP, ice-soil-pipeline interactions of buried pipelines were investigated by numerical...

... with deep ice gouges and ice keels interacting with buried pipelines. A common practice has been to bury the pipeline well below the deepest registered gouge mark in the relevant geographical area with the objective to limit the pipeline response. In order to render future projects in regions with severe...
