This paper deals with the numerical approach and technical implementation of the 6-DoF hydrodynamic modelling, combined with the Politecnico di Milano HexaFloat robot, adopted for wind tunnel Hybrid/HIL tests floating offshore wind turbines. The hybrid testing methodology, along with its ocean-basin counterpart, is currently being considered as a valuable upgrade in the model scale experiments, for its capability to get rid of the typical scaling issues of such systems. The work reports an overview of the setup, the general testing methodology, presenting the main challenges about the deployment on the realtime hardware, summarizing the key solving choices. A set of results related to code-to-code comparison between the optimized HIL numerical model and the reference FAST computations are included, confirming the correctness of the approach.
