Experimental Evaluation of Dynamic Rock Scour Protection in Morphodynamic Environments for Offshore Wind Jackets

Bottom-fixed offshore wind turbines are generally built on continental-shelf sections that morphodynamically active due to their shallow depths and severe wave current conditions. Such sites commonly protected against scour prevent the loss of structural stability. Scour protection can be designed using static or dynamic solutions. Designing requires experimental validation, especially for singular unconventional structures. This article presents an method laboratory analysis jacket foundations placed at sites. The test campaign was conducted within project East Anglia ONE (UK) as part asset owner studies aimed evaluate operation maintenance (O&M) aspects, independent contractor’s original design assessments. physical experiments explored morphodynamic changes sea bottom importance protection, well history loads deformation rock protection. by repeating different cumulative tests, including a succession randomly ordered states (Return Period (RP) 1-10-20-50 years). results show sour greatest when most energetic occurred beginning campaign. maximum 5D50 first also energetic, while it 3D50 not included test, yielding 40% reduction in deformation.
