Field trials of suction caissons in clay for offshore wind turbine foundations
TLDR
In this article, a program of testing on suction caisson foundations in an artificially prepared sand test bed near Luce Bay, in Scotland, is described, with the results relevant to the design of either monopod or quadruped foundations for offshore wind turbines.Abstract:
A programme of testing on suction caisson foundations in an artificially prepared sand test bed near Luce Bay, in Scotland, is described The tests are relevant to the design of either monopod or quadruped foundations for offshore wind turbines Records are presented for suction installation of the caissons, cyclic moment loading under both quasi-static and dynamic conditions to simulate the behaviour of a monopod foundation, and cyclic vertical loading and pullout of caissons to simulate one footing in a quadruped foundation Variations of stiffness with loading level of the foundation are observed, with high initial stiffness followed by hysteretic behaviour at moderate loads and degradation of response at high loads Some implications for the design of wind turbine foundations are briefly discussedread more
