A Physical Model Approach to Mooring Loads and Motion Responses of a Closed Fish Tank Including Internal Free Water

[Outline of Awards]
As an effort to expand aquaculture in coastal areas, semi-closed recirculating aquaculture systems are being developed in marine areas that are more closed and have relatively poor water quality than current aquaculture sites. This system can respond to various environmental changes and has many advantages in terms of operation and maintenance. However, there are issues with this system, such as the fact that it is subject to greater external forces from the natural environment than conventional net cages, and that sloshing, which causes the water surface inside the cage, to swell significantly, occurs. In this study, we used a rigid cage to investigate the sloshing that occurs in the cage tank in a wave field and the effects of its motion coupling, and devised a method to improve the practicality of rigid cages by incorporating a flexible net structure that suppresses sloshing.
