Influence of scour protection layers on the lateral response of monopile in dense sand

The scour protection layers are usually installed around the monopiles to prevent the formation of scour hole. While extensive studies have been performed on the effectiveness of scour protection layer as mitigation measure, no study to date has been found to quantify the influence of scour protection layer on the lateral response of...

Centrifuge modeling of the impact of local and global scour erosion on the monotonic lateral response of a monopile in sand

The majority of offshore wind turbines are founded on large-diameter, open-ended steel monopiles. Monopiles must resist lateral loads and overturning moments because of environmental (wind and wave) actions, whereas vertical loads tend to be comparatively small. Recent developments in turbine sizes and increases in hub heights have resulted...

The Impact of Installation Method on Monotonic Loading of Monopiles in Sand

Monopiles are the most commonly used foundations for offshore wind turbines (OWTs). To date these are mostly impact driven into the seabed using high-capacity hammers. The noise and vibrations caused by driving create environmental concerns and the increasing size of these foundations has resulted in alternative installation methods being...

Influence of vertical loading on behavior of laterally loaded foundation piles: A review

The majority of installed offshore wind turbines are supported on large-diameter, open-ended steel pile foundations, known as monopiles. These piles are subjected to vertical and lateral loads while in service. In current design practice, interaction of vertical and lateral loads are not considered, rather piles are designed to resist...
