Abstract

Suction caisson anchors are used widely for mooring offshore oil and gas drilling platforms, and being considered for tethering floating wind turbines in shallow waters with sandy sediments. Despite many uncertainties have been identified, their behaviour in calcareous sand remains unexplored. The performance during installation and under inclined loadings in calcareous sand has been investigated through centrifuge tests and finite element analyses. The revealed soil failure mechanisms provided insight into the behaviour. The degree of sand particle breakage and corresponding influences have been quantified. Design approaches have been proposed for assessing penetration resistance during installation, and capacity under operational loadings.
