Structural Model Test for Strength Performance Evaluation of Disconnectable Mooring Apparatuses Installed on Floating-Type Offshore Wind Turbine

The destructive power of typhoons has been continuously increasing due to the influence global warming. In a situation where installation floating wind turbines is around world, concerns about huge losses and collapses offshore strong are deepening. Regarding safe operation turbines, development new type disconnectable mooring system required. newly developed apparatuses, such as fairlead chain stoppers (FCS) submersible pulleys (SMP), considered in this study devised more easily attach or detach turbine with lines compared other systems. order investigate structural safety initial design FCS SMP that can be applied MW class floating-type scaled-down models were produced using 3-D printer, tests performed on those models. For models, tensile specimens acrylonitrile butadiene styrene material used printing process prepared, properties evaluated by performing tests. Finite element analyses applying obtained from same load boundary conditions model Through finite analyses, weak parts reviewed. considering main stopper, test results analyses. study, it was possible experimentally verify apparatuses. Furthermore, improve strength detailed stage.
