Abstract

The increasing demand for renewable energy requires efficient foundations supporting offshore wind energy structures. An offshore wind energy converter based on multiple suction bucket foundations is a promising alternative to common foundations. The design driving tensile bearing behaviour, especially the development of the pore pressure, still has significant uncertainties causing an inefficient design. This paper presents a new testing facility for axially loaded suction bucket foundations in sand. The facility enables model testing in different scales up to a diameter of the model of 500mm considering various load conditions with highly sophisticated data acquisition. First results show a strong dependency of the tensile bearing behaviour on the applied heave rate, which also affects the development of pore pressure. The results are compared to an analytical calculation method according to Senders.
