Background
The WAKEFUL project aims at studying the far-wake of a floating offshore wind turbine (FOWT) at full scale in real met-ocean conditions. The project takes benefit of a joint LiDAR experiment within VAMOS project gathering the University of Stuttgart, IDEOL and the LHEEA lab (Centrale Nantes – CNRS) around the characterization of the power curve, the close and the far wake of a floating wind turbine installed at the sea test site SEM-REV. The major objective of WAKEFUL is to measure the far wake of the FOWT, some hundred meters downstream the turbine, in order to understand its interactions with the floater motions and the atmospheric unsteady variations. The final goal of the project is to evaluate the ability of models to correctly predict the unsteady wake of a FOWT.
In the first part of this project, a dedicated motion compensation strategy (platform or/and post-processing) will be developed to compensate for the motion of the floater where the LiDAR will be installed.
The second part is dedicated to the measurement and analysis of the data collected.
The project will benefit from the presence of several LiDARs to analyze the far wake (scanning LiDAR) as function of the inflow conditions (nacelle-mounted LiDAR) the project will focus on the analysis of the temporal variations of the far wake (unsteady wake) and its meandering. The scanning LiDAR will also be used to provide datasets of atmospheric conditions.
Abstract
Introduced at Seanergy 2021, this poster presents 5 ways to fill the knowledge gap on offshore atmospheric conditions:
- long term observations at coastal locations;
- dedicated field campaigns using remote sensing;
- development of methodology to extract turbulent information
- meso-scale CFD modeling
- contribution to the physical understanding of the wind – wave coupling process
