Abstract

The paper presents an optimization methodology for comprehensive evaluation of a TLP support with multi-megawatt OWT. Design optimization based on principle dynamic properties of a TLP support system is performed, taking consideration of both resonances of rotational excitation frequency of the OWT and the second-order sum-frequency wave excitations. Reasonable engineering attributes verified by performances of the structure are derived with depth variation. The attributes of TLP support are applied in multi-criteria decision making method-TOPSIS for benchmarking of those feasibilities. The results illustrate the effectiveness of proposed methodology in MCDM combining with economical and environmental attributes together.
