Abstract

Reliable and predictable installation of suction bucket jacket foundations is critical for the operation of offshore wind turbines but may be challenging in soil stratigraphies where penetration resistance is high, as there are limits to achievable suction pressure due to cavitation and buckling of relatively thin-skirted buckets. Installation mitigation measures are often considered to overcome these challenges and optimise the suction buckets. However, the understanding of mitigation measures is limited. Therefore, in this thesis, suction bucket installation using pressure cycling is investigated with these practical challenges in mind.
