CFD models to assess the loads on floating marine energy convertor devices


A Computational Fluid Dynamics (CFD) package can accurately simulate the conditions endured by such devices in the marine environment. CFD tools are especially valuable for examining the loads experienced by wave energy devices and floating moored structures. For the detailed evaluation of a marine energy structure, there is often no substitute for physical testing. Testing of appropriately scaled devices in a laboratory provides reliable validation of designs for both operational and extreme conditions. The company’s


physical modelling laboratories are equipped with state-of-the-art instrumentation, including multi- element random wave makers with active wave absorption, laser scanners, video capture and infrared tracking systems. Physical models have been applied to a range of marine energy convertor systems, for example they have been used to optimise the design of impounding structures for tidal lagoons or barrages.


In its Fast Flow Facility, HR Wallingford carries out stability assessments


of the foundations and cables by simulating seabed roughness with strong waves and currents to examine site selection and asset integrity under storm conditions.


Samantha Dawson, Renewables Business Manager explained: “Our work helps to optimise investment return and minimise the environmental impacts of marine renewable energy projects, informing every phase of the development cycle. The combination of our detailed computational and physical modelling and specialist knowledge, adds confidence, helping to lower risk for both developers and investors.”
