Centrifuge modelling of anchor piles under multi-directional loading for floating wind turbines
Centrifuge modelling of anchor piles under multi-directional loading for floating wind turbines
The current frontier for the offshore wind industry lies in achieving economic and technical viability for floating structures, facilitating the development of deeper wind farms previously inaccessible with bottom-fixed structures. This paper presents an innovative experimental centrifuge set-up developed as part of the MUTANC project to investigate the behaviour of shared anchors to multi-directional horizontal loads, mimicking the effects of multiple catenary mooring lines acting simultaneously on a typical anchor pile. A steel model pile equipped with fibre optic sensing allows for the recording of normal strains along the pile shaft and bending moment, enabling the derivation of soil reaction and pile deflection. The paper also investigates the potential decoupling of loading in perpendicular directions and outlines preferred responses to various monotonic multidirectional load paths. The results validate the setup's reliability, serving as a benchmark for subsequent cyclic tests to generate an innovative database for the validation of numerical models.
