AB - The cost of foundations supporting offshore wind turbines (OWT) continue to influence the feasibility of new developments and the speed at which new sources of renewable energy are brought online. A technical challenge remains to design OWT foundations efficiently, accounting for the impact of long-term cyclic environmental actions. The combined effects ofaccumulated deformation and soil stiffness evolution with long-term cyclic loading have consequences for both serviceability and fatigue limit state design. Recent work on the implementation of the high-cycle accumulation framework to model the lifetime behaviour of offshore monopile foundations subject to lateral cyclic loading and validation against field tests is first summarised. Thisincludes site-specific calibration procedures for a dense marine sand at Dunkirk and a glacial till at Cowden, demonstrating the field scale response can be reproduced well by calibrating the models using only in-situ CPT data and cyclic triaxial laboratory tests with initial conditions close to those encountered in-situ. Normalisation of results from sets of parametric numerical analyses of referencemonopiles founded in uniform sands and layered sand-and-clay stratigraphy are finally presented. These can inform rapid prototyping of foundation solutions at optioneering stage and can be interrogated for use in reliability-based design methods.
