| The design of wave energy mooring systems is challenging: overdesign incurs a significant cost penalty, underdesign may lead to a premature failure and incorrect design could reduce the power production. Consequently, compliant mooring systems are being developed for wave energy applications. This paper presents tank test results for a scale model of the buoy and mooring used at the SouthWest Mooring Test Facility (SWMTF), an offshore facility developed to conduct long-term sea trials for wave energy device moorings. A compliant three leg catenary mooring system using Nylon ropes in the water column is investigated. Preliminary static, quasi-static, decay, regular and irregular wave tests were conducted on the 1:5 scale model, using the Ifremer basin in... |

| Many marine renewable energy (MRE) conversion systems including wave, floating wind, Ocean Thermal Energy Conversion (OTEC) and some tidal energy devices, are moored in place. The choice of mooring system is critical as it directly affects installation, energy take-off, and long term reliability, and hence has a significant influence on costs. Installation has been estimated to account for 27% of lifetime cost for a tidal turbine [1]. This is an area where the other marine industries, notably offshore oil and gas, have extensive experience, but the high energy regions in which MRE devices are deployed pose particular installation difficulties and operating conditions. There has been a strong movement towards replacing steel with synthetic fiber ropes... |
