Both wind turbine and tidal turbine are studied regarding their hydrodynamic interactions with the flow and the seabed. Those studies reveal flow fields around the tidal turbine and in the wind farm, scour at the turbine foundation and flow impacts on the structures. Research is also being carried out to evaluate tidal potential energy (barrage) using in-house modelling code and open-source code including assessment of engineering schemes and impact of the structure and operation on the estuarine process and the surrounding open seas, such as sediment transport regime and morphological evolution. Recent research has extended to cover offshore communication cables and pipelines.
