摘要

Offshore floating platforms are increasingly being examined for their possibilities of harvesting wave and wind energy in addition to oil and gas exploration functions. The current experimental studies are focused on the design and development of the TSUSUCA DOLPHIN. TSUSUCA is a coined word that is abbreviated as Tsunami Protection Solar Power Utilization and coastal applications. This new multi-purpose floating device can be a wave energy convertor and a tsunami barrier. A bio-inspired dolphin-shaped body is combined with a linear motion electricity generator (LMEG) that is hinged at the top of the base block. The proposed design distinguishes it from the other wave energy converters that operate in normal sea states. TSUSUCA DOLPHIN, designed for the near-shore conditions, is experimentally investigated under regular waves to compare its performance under different inputs. In a few cases considered in the study, hydropower obtained from the device recorded an efficiency of about 32% and the electrical power efficiency of LMEG is about 30.07%. The proof of concept is successfully demonstrated by the bio-inspired device’s performance. This research lays the groundwork for future developments in this area by facilitating the creation of further devices that target the use of wave energy.
