Abstract

This paper deals with a case study on the wave height reduction behind floating Wave Dragon wave energy converters in Santander Bay, Spain. The study is performed using the MIKE21 Boussinesq model from DHI. The Wave Dragon transmission characteristics in the numerical wave propagation model are based on previously performed physical model tests in scale 1:51. Typical winter storm conditions are considered in the case study together with different stiffness in the mooring system of the floating device. From the study it is found that if multiple Wave Dragons are positioned in a farm the wave power along the shorelines in Santander Bay is reduced by approximately 50% when using the farm layout of that provides the best overall compromise between coastal protection and electricity production. Moreover, it is concluded that a farm of devices can be modelled with good accuracy using a homogeneous porosity structure instead of implementing each device with detailed geometry.
