The paper focuses on floating offshore wind turbine (FOWT) and makes a review of famous designs. FOWT foundation is classified into three categories based on the strategy to achieve static stability. In order for utilization, a new concept is proposed and primary design for water depth of 90m is described. Moreover, dynamic analysis of this concept under operational condition is carried out. The thrust force on the rotor is evaluated based on software analysis; the hydrodynamic forces are calculated using Morison equation. The results indicate that the concept is excellent and worth for further development.
