Abstract
Suction caissons are widely used as foundations for fixed wind turbines, floating wind systems, and subsea manifold systems due to their robust capacity to withstand environmental loads. Although the effect of torsion on the bearing capacity of suction caisson has been extensively studied, the influence of consolidation has not been adequately considered, despite its potential to enhance capacity and serve as a viable method to mitigate the reduction caused by torsional loading. This paper investigates the bearing capacity of suction caissons under combined V-H-M-T loading and the influence of consolidation on the failure envelope through coupled small-strain finite element analyses. A series of expressions for failure envelopes are proposed, and a generalized method is introduced to predict the consolidated failure envelope for any degree of preloading and consolidation.
