Abstract

Ocean waves hold great promise as a renewable energy source, yet effectively harnessing this energy necessitates the enhancements of technologies. Despite the advancements in Wave Energy Converters (WECs), several current limitations in wave energy harvesting technologies hinder widespread commercial adoption. WECs have demonstrated their potential for electrical power generation but there is a recognition that a single type of energy harvesting mechanism may not fully exploit the vast energy potential of the marine environment. This study explores Vortex Induced Vibrations (VIV) as a complementary energy har-vesting mechanism for WECs: the basic idea is to exploit wave-induced VIV. The paper investigates the viability of this approach, focusing on clarifying the necessary conditions required to enable this innovative energy harvesting approach. The results provided in this paper contribute to a deeper understanding of the practicality of wave induced VIV harvesting, highlighting some potential challenges associated with deploying such a system.
