Scour protection is a requirement of many offshore projects for foundations, pipelines and cables. Standard methods adopt a static protection where the top layer of armour is designed to resist hydraulic loading. The size of rock required to provide stability under stormwaves and currents close to a structure is often predicted to be large and may be difficult to place accurately in large quantities. One solution to this problem is to consider using smaller rock where the performance is evaluated in terms of a damage parameter. Potentially this allows for dynamic reshaping of the scour protection whilst still providing a specified reduction in foundation scour depth and volume. The paper presents a new set of experiments examining the relationship between armour rock size, armour layer thickness and the resulting stability analysed in terms of Shields parameter.
