| Abstract | Offshore renewables particularly wind- are expected to expand at a very fast pace in the next decades. These installations need to be fixed or anchored to produce energy. In most cases that will be achieved by pushing or driving large steel pieces into the sea bottom. That installation process is difficult because of the unprecedented scale of some of these foundations (monopiles), because the conditions at the bottom are poorly known and because working in the middle of the sea leaves little room for error. Apart from its inherent difficulty, the installation process essentially modifies the ground around the foundation. As a result of those changes, there are still some important gaps in our ability to predict properties that are basic for safe and efficient operation, such as axial capacity of anchors or lateral stiffness of monopiles. This project will address these problems by developing and validating simulation tools -operating both at the continuum scale and at the micromechanical or grain scale- that represent faithfully offshore foundation installation procedures. It will do so by exploiting a unique set of geotechnical simulation tools developed by our team during the last decade. In particular the specific problems treated are: the installation of suction-caissons in layered soils; the effect of monopile installation on lateral stiffness; the effect of installation mode on side shear set-up. | ||
