Spudcan-Pile Interaction during Installation of Piles for Offshore Wind Turbines
Spudcan-Pile Interaction during Installation of Piles for Offshore Wind Turbines
This work investigates the effects of the pile installation process on spudcans used as temporary foundations, employing numerical analysis to incorporate large deformations, dynamic wave propagation, and hydro-mechanical coupling for the first time. A hydro-mechanically coupled Coupled Eulerian-Lagrangian (CEL) method is employed to meet these requirements. The simulations aim to replicate the full process of spudcan penetration in the seabed, followed by the pile driving process. This is realised in a fully explicit time integration scheme, for which a method is outlined to achieve a static equilibrium of the spudcan prior to the start of the pile driving process. The results reveal that with decreasing distance between the pile and spudcan, the spudcan is influenced by the pile installation process, leading to additional settlements.
