Dynamic Analysis of a Monopile Offshore Wind Support Structure Subjected to Earthquakes: A Comparative Study Between the Responses of an Elastic and an Inelastic Soil-Structure Interaction Model Through Incremental Dynamic Analysis

This thesis project has set out to investigate the response in fore-aft direction of a monopile wind foundation supporting an NREL 5MW turbine, offshore the coast of Taiwan, which is affected by weak to strong earthquake ground motion in combination with normal sea state conditions. The soil at the location of the monopile is layered, with sand...

Developing the Vibro-drill: A feasibility study into an improved installation method for offshore foundation piles

To meet the demand for renewable energy sources, large numbers of offshore windfarms are planned to be constructed in the near future. The majority of the foundations for these offshore wind turbines are large-diameter monopiles. The driving of monopiles into the seabed is conventionally done using a hydraulic hammer, this process is commonly...
