ABSTRACT
Currently, majority of OWT around the globe have monopiles as their foundation system. However, with increase in water depth, diameter of monopile required for such cases increases to a greater extent. To address this issue, a new cost-effective foundation system is needed. In this paper, hybrid monopile foundation has been reviewed that is a combination of monopile and gravity foundation. This new foundation structure fared exceptionally well in a number of centrifuge tests under both static and dynamic loading conditions. Hybrid monopiles have been found to be effective for reducing lateral deflection and improving bearing capacity. Hybrid monopiles have also been proven to minimize the susceptibility to liquefaction. In the paper various parametric studies have been reviewed pertaining to hybrid monopile foundation for both static and dynamic loads. The aim of this paper is to critically review and discuss the hybrid monopile foundation and identify its future scope.
