The installation of wind turbines offshore, due to the steeper wind shear, higher wind speeds and less competition for space compared to on-land, needs to be economically viable and capable of competing with alternate technologies in the energy market. The cost of production and installation of fixed structures in deeper waters (i.e.>60 m), is not competitive. A viable solution is the use of floating substructures, floating offshore wind turbines (FOWT), attached to the seabed by mooring lines and anchors. However, the motions of a FOWT exposed to the environmental conditions at sea will be different and added aspects need to be taken into account when designing these structures. For example, the coupled effects between the turbine and the floater will influence the performance of the turbine. Aerodynamic loads will contribute for the damping of the system, the mean aerodynamic thrust loads will have an impact on the mooring loads and the mean torque on the rotor will generate heeling moments on the rotor. Additionally, gyroscopic moments for some types of floating structures may be significant, which may excite unwanted motions, for example yaw moments.

由于风切变更陡，风速更高，与陆地相比对空间的竞争更少，海上风力涡轮机的安装需要经济上可行，并且能够与能源市场上的替代技术竞争。在较深沃茨（即> #36825;，没有竞争力。一个可行的解决方案是使用浮动子结构，浮动海上风力涡轮机（FOWT），通过系泊线和锚连接到海底。然而，暴露于海上环境条件下的FOWT的运动将是不同的，并且在设计这些结构时需要考虑其他方面。例如，涡轮机和浮子之间的耦合效应将影响涡轮机的性能。气动载荷将有助于系统的阻尼，平均气动推力载荷将对系泊载荷产生影响，转子上的平均扭矩将在转子上产生横倾力矩。此外，某些类型的浮式结构的陀螺力矩可能很大，这可能激发不希望的运动，例如偏航力矩。
