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...

Impact of scour on lateral resistance of wind turbine monopiles: An experimental study

The majority of offshore wind structures are supported on large-diameter, rigid monopile foundations. These piles may be subjected to scour due to the waves and currents that causes a loss of soil support and consequently decreases the pile capacity and system stiffness. The results of numerical models suggest that the shape of the scour hole...

Response of monopiles subjected to combined vertical and lateral loads, lateral cyclic load, and scour erosion in sand

Although wind energy capacity has increased significantly in the last few decades, the installed capacity of offshore wind turbine still lags far behind that of onshore wind turbines due to the installation and foundation cost. The aim of this research project has been to clarify the influence of combined vertical and lateral loads, lateral...

Influence of scour depth and type on p–y curves for monopiles in sand under monotonic lateral loading in a geotechnical centrifuge

The influence of scour on the lateral response of monopile foundations for offshore wind turbines is investigated in this paper. Application of lateral load-displacement (p-y) curves to predict the lateral pile behaviour is subject to uncertainty as many of the presently used design approaches have been derived for long, slender piles. These...

Optimizing The Installation of steel, Open-Ended Piles Through Impact Hammering For Offshore Applications: A Parametric, Experimental Study In The Geocentrifuge

As a result of population growth and economical prosperity, energy consumption has been on the rise for decades. Present-day projections predict the continuation of this trend with the rapid industrialization of former second world countries. Together with the rise of energy demand, incentives fo the scientific community to quantify the...
