简介：一个拍动类型波浪精力变换器(WEC)与nearshore防波提被相结合经济地并且环境地扩展WEC的申请。基于线性潜在的理论，一个特徵函数扩大答案为暴露于正常波浪的依赖底部的拍动类型WEC的周期的排被开发。另外，粘滞效果用卷解决方案方法，一个粘滞的抑制术语在运动的方程包括了的轮船被考虑，并且粘滞的抑制表达式也被描述。建议答案被比较与出版文学验证。包括波浪精力变换效率的结果，事件波浪精力的反映并且播送的比例为波浪时期和几何比率的一个范围被介绍。更好的波浪保护效果能与在WEC之间的更小的差距被达到，这被表明，在事件波浪精力的播送比例更低的地方。最佳的几何比率因此为给定的波浪力量吸收和一个特定的波浪时期存在。
