The assessment of scour risk at offshore foundations is dependent on a number of different factors including metocean conditions, water depth, soil conditions and structure dimensions and layout. At foundations where the soils are dominated by non-cohesive soils the scour risk is potentially greater than for clay dominated sites. However, even in those locations where sand overlies less erodible soils, it is important to understand the possible time-scale for the loss of this material. Further, as the location of foundation structures moves further offshore into deeper water, not only does the scour process change, the scour development is likely to become event duration limited. However, this latter effect may not only be confined to deeper water sites, but to sites where the metocean conditions are constrained (e.g. weak tidal currents, limited fetch lengths etc). This paper explores the importance of this effect through the use of a time-evolution model of scour.
