A feasibility study of reducing scour around monopile foundation using a tidal current turbine

The monopile foundations of offshore wind turbines in shallow waters are susceptible to be affected by tidal scour, which takes away the sand and soil around monopiles poses a serious threat safety turbines. To mitigate this issue, much effort has been made previously. However, all existing protective measures do not have added value other than scouring mitigation. In view this, new scour mitigation measure that utilizes current turbine (TCT) is investigated study, can only reduce foundation but also generate clean power simultaneously. research, proposed method studied using combined numerical simulation laboratory testing approach. Both calculation experimental results shown TCT installed front an does positive role reducing when it generates electricity meantime. Moreover, contribution reduction further improved through optimizing its installation position turbine.
