Hot on the Heels of Catriona Macdonald post on a new open report from British Geological Survey on layered soils in the North Sea (as part of our EPSRC CBRA, Cable Burial Risk Assessment project led by Durham University) our next paper is out. This paper looks at Centrifige Modelling to investigate the penetration of a ship anchor in layered sands and through realistic trenches formed by cable and v-shaped ploughs. It also allowed us to look at what the pipeline/cable backfill density really is, loose just after backfilling, no surprises. Maybe this will help answer how layered soils can be incorporated in a new CBRA and what along with updated soil factors, different anchor types and speed effects also need to be considered (all things our project has considered). Thanks to our co-authors and project team for all their help getting the paper over the line Yaseen Sharif Duncan Stevens Robert Bird Will Coombs Charles Augarde Catriona Macdonald. What's next? Robert Bird Will Coombs are currently running loads of parallel simulations using their efficient open source MPM code to look at lots of additional layered soil combinations for different anchor types. All useful for developing improved penetration prediction tools and contributing to the next generation of CBRA.
