“…More details can be found in the work by Jonkman et al [32,33]. It should be mentioned that nowadays, the offshore wind industry is developing so rapidly that upscale wind turbines of rated power beyond 10 MW would be employed in the near future [34][35][36][37]. In this study as our focus is on the feasibility and performance of the FOWT-SFFC concept, the NREL 5 MW wind turbine suffices to meet the requirement of analyses.…”

A state-of-the-art concept integrating a deepwater floating offshore wind turbine with a steel fish-farming cage (FOWT-SFFC) is presented in this paper. The configurations of this floating structure are given in detail, showing that the multi-megawatt wind turbine sitting on the cage foundation possesses excellent hydrostatic stability. The motion response amplitude operators (RAOs) calculated by the potential-flow program WAMIT demonstrate that the hydrodynamic performance of FOWT-SFFC is much better than OC3Hywind spar and OC4DeepCwind semisubmersible wind turbines. The aero-hydro-servo-elastic modeling and time-domain simulations are carried out by FAST to investigate the dynamic response of FOWT-SFFC for several environmental conditions. The short-term extreme stochastic response reveals that the dynamic behavior of FOWT-SFFC outperforms its counterparts. From the seakeeping and structural dynamic views, it is a very competitive and promising candidate in offshore industry for both power exploitation and aquaculture in deep waters.

“…More specifically, it consists of two main hardware components: (a) the wind turbine, which is a 1/75 aeroelastic scale model of the DTU 10 MW reference wind turbine ( [8], [10]). The wind turbine model has IPC capabilities [11] and, thanks to a dedicated real-time controller, offers the possibility to implement FOWTspecific control strategies [12] for experimental Hybrid/HIL validation; (b) the Hexafloat 6DoF robot [6] provides motion to the wind turbine model, moving its base by means of an independent real-time controller, [13], (c) a 6-components dynamometric balance installed between the turbine model tower base and the Hex-aFloat's end effector, measures the internal actions between the floater and the turbine (i.e. aerodynamic and inertial forces).…”

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.

“…LIFES50+ is an H2020 EU project [8], which is aimed at testing cost effective technology for floating substructures for 10 MW offshore wind turbines, at water depths greater than 50 m. The objective is optimizing and qualifying, to a Technology-Readiness-Level (TRL) of 5, two innovative substructures designed for 10 MW wind turbines. One of the most important factors to take into consideration for this particular application, is the combination of the aerodynamic loads, caused by the wind turbine, with the hydrodynamic ones, caused by the physical interaction between the turbine, the floating platform and the sea.…”

This article focuses on a Hardware-In-the-Loop application developed from the advanced energy field project LIFES50+. The aim is to replicate, inside a wind gallery test facility, the combined effect of aerodynamic and hydrodynamic loads on a floating wind turbine model for offshore energy production, using a force controlled robotic device, emulating floating substructure's behaviour. In addition to well known real-time Hardware-In-the-Loop (HIL) issues, the particular application presented has stringent safety requirements of the HIL equipment and difficult to predict operating conditions, so that extra computational efforts have to be spent running specific safety algorithms and achieving desired performance. To meet project requirements, a high performance software architecture based on Position-Based-Admittance-Control (PBAC) is presented, combining low level motion interpolation techniques, efficient motion planning, based on buffer management and Time-base control, and advanced high level safety algorithms, implemented in a rapid real-time control architecture.
