Wave tank testing of a multi-purpose floating platform with aquaculture, wind turbine and wave energy converters

Résumé

Abstract This paper aims to describe the set-up and some results of a 1/40 scale experiment on an innovative multi-purpose floating platform. The raw dataset of the experimental measurements collected is published in [1]. The experiment was carried out in October 2019 in the framework of the Blue Growth Farm project (EU-H2020, G.A. n.774426). The objective of the project was to develop and demonstrate a modular, environmentally-friendly, automated floating platform, devoted to aquaculture and wind-wave energy production. The experiment was aimed at assessing the main features of the coupled dynamics of the novel platform concept and at providing data for numerical models validation. The tests were carried out in the 50mx30mx5m hydrodynamic and ocean engineering tank of Centrale Nantes, under several combinations of simulated wind-wave conditions. The 1:40 wind turbine was represented by a Software-In-The-Loop approach, while four aerial lines were used to reproduce the mooring system. The model was also equipped with a set of oscillating water column (OWC) wave energy converters (WECs) and a scaled model of the aquaculture net cages. This paper presents some of the results obtained under free decay and regular wave test conditions, without wind. In particular, platform motions in surge, heave and pitch are analyzed. To assess the impact of the WECs and of the cage models on the overall structure dynamics, three different structure configurations are compared and some conclusions about the coupling effects between these technologies and platform motions are drawn.
