海浪能是最有前途的可再生能源之一，尽管相关技术在全球能源市场上还不够成熟，与太阳能、风能和潮流装置相比还没有竞争力。特别是，在过去十年开发的各种波能转换器中，垂荡点吸收器代表了最可行和研究的技术之一，如过去几年在世界各地部署的小规模测试和全尺寸原型所示。然而，进一步降低能量生产成本的需要需要波浪能转换器的专门设计，考虑到由动力输出单元和设备操作轮廓提供的限制。因此，实际分析的重点是一个新的基于成本的设计程序的垂荡点吸收。该设备配备了一个浮动浮标，其具有通过张紧线连接到动力输出装置的可选完全浸没质量。它由一个永磁直线发电机组成，位于海底，并配备了重力基础。所提出的程序适用于几个候选人部署地点位于地中海的发病率的动力输出限制和转换器的操作配置文件进行了充分的调查，并提供了一些初步设计的波能转换器设备的建议。目前的结果表明，有很大的范围，使波能部门在国际市场上更具竞争力，通过适当选择点吸收器的主要设计参数，在部署现场的海洋条件的基础上。
Sea wave energy is one of the most promising renewable sources, even if relevant technology is not mature enough for the global energy market and is not yet competitive if compared with solar, wind and tidal current devices. Particularly, among the variety of wave energy converters developed in the last decade, heaving point absorbers represent one of the most feasible and studied technologies, as shown by the small-scale testing and full-scale prototypes, deployed in the last years throughout the world. Nevertheless, the need for further reduction of the energy production costs requires a specialized design of wave energy converters, accounting for the restraints provided by the power take-off unit and the device operational profile. Hence, actual analysis focuses on a new cost-based design procedure for heaving point absorbers. The device is equipped with a floating buoy with an optional fully submerged mass connected, by means of a tensioned line, to the power take-off unit. It consists of a permanent magnet linear generator, lying on the seabed and equipped with a gravity-based foundation. The proposed procedure is applied to several candidate deployment sites located in the Mediterranean Sea; the incidence of the power take-off restraint and the converter operational profile is fully investigated and some recommendations for preliminary design of wave energy converter devices are provided. Current results show that there is wide scope to make the wave energy sector more competitive on the international market, by properly selecting the main design parameters of point absorbers, on the basis of met-ocean conditions at the deployment site.
