In order to obtain more wind energy, offshore wind farms tend to be constructed in deeper water with larger wind turbines. Various kinds of support structures, including gravity base structures, are considered to reduce the CAPEX of wind farms. In this paper, feasibility of floated gravity base structures is investigated through floating stability analysis on lowering operations during the installation. In regard to the baseline model for 30 m water depth with the spherical base and the top diameter of 6 m, the floating stabilities are derived by varying the base diameter and the draft. As it is assumed that the structures are ballasted with sea water during the installation step, free surface effects are taken into account. The relevant structures satisfying the floating stability requirement are derived. It is shown that the structure should be equipped with the bulkheads to satisfy this requirement. Furthermore, the geometry of gravity base structure which minimize the weight of the structure is investigated.
