Abstract

 A series of water tank experiments have been performed to investigate the hydroelastic behavior of module-linked floating structures with various connector and mooring stiffness. Wet-mode free vibration properties and regular wave responses of two different shapes of floating structures are measured. A hexagon is selected as the planar shape of each module. Magnetic connectors are used for quickly assembling and disassembling multiple modules with each other. Tensioned springs are arranged over the bottom surfaces of module as a tension-leg mooring system. A pulley mechanism is introduced to maintain uniformly distributed tensile forces in springs. Experimental results are compared with analytical ones using a fluid-structure coupled model. The structure is idealized by twodimensional mass-spring system, whereas fluid domain is modeled by boundary elements.
