... structure consists of two box-shaped bodies joined by flexible beam elements. Due to the wave excitation, the floaters experience relative pitch rotations and vertical displacements, which dynamically deform the piezoelectric linking element, producing electricity. As an illustrative example, the system...

... substation. The scale of wind farms will be larger and larger in the future (IRENA, 2019), therefore, the weather and sea conditions in a large wind farm will not be able to be treated as uniform. The damage risk on floaters and mooring systems will be different under the nonuniform weather and sea condition...
