Embodiment Construction
[0051] The mooring cable of offshore wind turbine is a very important part of the wind turbine. Its function is to control the position of the floating wind turbine. Therefore, the safety and applicability of the mooring cable are also extremely critical.
[0052] Compared with other types of floating fans, the unique deep-draft single-column structure of the SPAR floating fan results in an excessively large front flow area. Under the action of the incoming flow, the vortex shedding is likely to occur behind the fan base structure, and then the vortex induced by the fan occurs. movement phenomenon. The vortex-induced motion for a long time may lead to the damage of the mooring system. Therefore, when studying the motion response of the SPAR-type floating fan and the fatigue life of the mooring cable, the influence of the vortex-induced motion phenomenon must be considered. The research results will guide the future Engineering design has important reference and guiding signifi...
