ABSTRACT
Centrifuge modelling has been used extensively over the last five decades to address offshore geotechnical challenges associated with oil and gas developments. In recent years, the development of offshore renewable energy devices and structures, including wind turbines and wave energy converters has increasingly mobilised the offshore geotechnical engineering community. This paper revisits the use of centrifuge modelling for offshore geotechnics in the light of the new challenges raised by offshore renewable energy developments. This is illustrated through some aspects of foundation loading regimes such as dynamic tensile loading and multidirectional loading over a large number of cycles, which are specific to offshore renewable energy applications. The emphasis is on the modelling techniques developed to address these challenges and the opportunities provided by centrifuge modelling.
