| Abstract: | Offshore Wind Turbines has generally matured during the last decade with an annually energy capacity exceeding 1GW. A key factor for further large scale development of offshore wind energy is a cost of energy reduction. Designing foundations for Offshore Wind Turbines (OWTs) are challenging as these are dynamically sensitive structures in the sense that natural frequencies of these structures are very close to the forcing frequencies of the wind, wave and 1P (rotor frequency) and 2P/3P (blade shadowing frequency) loading. Typically for the widely used soft-stiff design (target frequency of the overall wind turbine is between 1P and 2P/3P), the ratio of forcing frequency to natural frequency is very close to 1 and as a result is prone to dynamic amplification of responses such as deflection/rotation which may enhance the fatigue damage, thereby reducing the intended design life. Therefore, a designer apart from accurately predicting the natural frequency of the structure must also ensure that the overall natural frequency due to dynamic-soil-structure-interaction does not shift towards the forcing frequencies making the value of even closer to 1. Therefore foundations are one of critical components of Offshore Wind Turbines not only because of the overall stability of the structure but also due to financial viability of the project. |
