Dynamics of a Dual Offshore Renewable Energy System: Analysis of Wind and Tidal Turbine

Offshore renewable energy has been showing remarkable growth and acceptable yields over recent years, the concept of this study centres on the idea of connecting a wind turbine to a tidal turbine, where both energy sources may be utilised at any one location for maximum energy yield. AutoCAD and MATHCAD have been used to simulate the aerodynamics and hydrodynamics of the structure. The power generation and risk analysis were also accounted for. The result of a wave spectral analysis effect on tidal turbines is demonstrated in the study for 6 different cases at different mean crossing period, wave heights, and fatigue life. The power generation of 2 bladed wind/tidal turbine versus 3 bladed was calculated. Although 3 bladed turbines have a marginal higher power generation output, this does not reflect the feasibility of the extra percentages of power on the economics
