SWiM – Solar and Wind in the Belgian Marine Zone – will conduct research on the combination of marine technologies in the Exclusive Economic Zone of Belgium, in particular to integrate Offshore Floating Photovoltaics (OFPV) in wind farms in an ecologically sustainable way. On the one hand, the project will investigate the technical performance of the OFPV structures, while it will provide knowledge on the ecological effects of such arrays on the other hand. RBINS MARECO and ECOMOD groups are involved in the latter aspect through a combination of experimental work and modelling approaches.
