South West Mooring Test Facility (SWMTF)
The research challenge is to develop a thorough understanding of mooring system behaviour of Offshore Renewable Energy (ORE) systems in real wave, wind, current and tidal conditions; and to improve computer simulation models and robust design procedures that allow the design of reliable, yet economic mooring systems.
The intention for the SWMTF research facility is to identify uncertainties for moored ORE systems that will respond in a coupled fashion. Instead of using tank tests, prototype installations and numerical analysis to support the design of a WEC, the data gathered from the test facility will be used to calibrate numerical models, enhance the physical understanding of the coupled behaviour and obtain understanding of component loading and deterioration.
