Tension Leg Platforms (TLP) have started to become popular structures both in offshore oil extraction and wind energy sectors. A challenging topic in this field has arisen by the adoption of TLP based wind turbines (TLPWT) into intermediate water depths. In this study, a TLPWT has been geometrically optimized for the coordinates of 03°E 56°N offshore of UK in the North Sea. Focused on the exciting wave forces, an optimization has been carried out to find out the geometrical shape yielding least wave forces on the structure, which depict the fundamental force component under the defined circumstances. The structural dimensions of the TLP have been obtained by solving for the least displacement and satisfying the limits for natural frequency and surge displacement values and it has been found that an 8567 tonnes of displacement is optimum. Based on the result achieved and related structural dimensions stated below, it can be concluded that TLPWTs are far from being feasible in shallow regions, where the main limitation rises due to the drastical reduction in the surge natural frequency of the structure in intermediate and shallow water depths.
