| Outline of Final Research Achievements |
Fishes are easy to be gathered around fish aggregating devices (FADs), which is an environment-friendly artificial ocean infrastructure. This study has proposed
and developed a new type of FAD with an ocean energy harvester to generate an independent electric power for navigational and environmental sensors, specially at archipelago areas with fishery and aquaculture. The characteristics of fluid force on FAD were investigated by numerical and theoretical works assuming steady state in time and the motions of FAD were also examined by experimental works. The proposed FAD can achieve 15% reduction for averaged snap load and 30% for maximum one. The amplitudes of surge, sway and heave motions excited by vortex-induced vibration (VIV) in wave-current conditions can be reduced up to 50%. Generated electric power by the optimized energy harvester was estimated at a typical archipelago area.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で提案・開発した浮魚層型海洋エネルギー発電プラットフォーム（FFB）は，漁礁周辺を回遊する魚群の一例として利用可能であるまた，FFBは，このような海洋環境を維持・発展させつつ，新たな発電機能を付加価値として創出する．そのため，電源確保の厳しい沿岸・外洋域において，集魚灯，航路灯，海洋環境および防災情報などの無線センサー機器への電力供給が可能となり，漁業資源・漁業者との共生・独立電源型の海洋エネルギーハーベスティング技術になり得ると考えられる．また，得られた知見・技術は，係留型浮体構造物の設計指針にも応用できるものである．
