In Arctic regions, ice scour imposes a potential danger to seabed facilities such as pipelines. The purpose is to define the subscour forces and displacements, and thus, create a soundly based design methodology. This work is an outgrowth of the Pressure Ridge Ice Scour Experiment (PRISE). This effort is an adjunct study to Project No. 191.
This work included the development of a soil/pipe interaction engineering model. The model was verified and calibrated through finite element analysis and interpretation of a series of physical model tests conducted in a centrifuge. This soil/pipe interaction engineering model is one of the first working tools for the analysis and design of seabed pipelines in ice-scoured environments. A final report has been issued.
