Club Member Curtis S. shared some insight on the project that he has been helping out with. Grad Student, Sara A. has been working on a project, as is mentioned below, that "investigates the yaw dynamics of the spar type floating wind turbine"
Here is an excerpt from Sara's paper.
The primary goal of the basin model test is to properly scale and develop a 1/150th scale 5 MW wind turbine that can be used to accurately capture real data of the rigid body motions and yaw performance of the model. The design is based on 5 MW spar-type floating wind turbine designed by the National Renewable Energy Laboratory (NREL). The baseline turbine has a rotor diameter of 126 m, a hub height of 90 m and a total weight of 700 metric tons. The turbine is rated to produce 5 MW. The spar platform characteristics are based on the OC3-Hywind (The Offshore Code Comparison Collaboration) model. The model is 10 m shorter than the referenced NREL 5 MW tower to account for the spary-buoy floating platform .
This project aims to investigate the yaw dynamics of the spar type floating wind turbine known as the OC3-Hywind concept. The location of the yaw system on the turbine is evaluated based on two models: between the tower and nacelle, and directly above the floating buoy. By changing the location of the yaw system of the OC3-Hywind turbine, the response characteristics of motions and other critical parameters of the system are expected to experience fluctuations and thus different power output. The experimentation will be conducted in the Turbulence and Energy Laboratory. The basin is 7 m long and 2.5 m wide, with an overall depth of 2.5 m.
We are using the ballast stabilized model, also called a spar buoy"
I can't wait to see the final project!
