This presents not only a challenge to deploying devices in such conditions but also an opportunity for developing combined hybrid platforms that harvest both wind and wave energy. This paper introduces the novel tension moored combined wind and wave energy converter (WEC): TWindWave. Numerical modelling of the system in power production and novel survival modes is undertaken. Hydrodynamic interaction is analysed and shown to reduce the overall WEC power production. The addition of the WECs onto platform characteristics is described. Novel survival modes which involve ballasting the WEC floats and sinking them along the platform columns, before they rotate around the column and pontoon connecting bends are described and analysed. Future work incorporating these results and more advanced techniques are proposed.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||European Wave and Tidal Energy Conference||Copyright (published version):||2017 European Wave and Tidal Energy Conference||Keywords:||Combined; Hybrid; Wind Turbine; WEC; Point Absorber; Torus; TLP; Survival Mode||Other versions:||https://ewtec.org/ewtec-2017/||Language:||en||Status of Item:||Unspecified||Is part of:||European Wave and Tidal Energy Conference (EWTEC) Series 2017||Conference Details:||12th European Wave and Tidal Energy Conference (EWTEC), University College Cork, Ireland, 27-September 1 August 2017|
