Abstract
Hybrid wind and wave platforms are among the most promising tech-nologies to foster access to untapped renewable energy in deep seas. This tech-nology aims to leverage synergies between wave and wind conversion systems by sharing costs, such as mooring and electrical connection, and combining their power production. The platform is usually a floating offshore wind turbine (FOWT) integrated with one or more wave energy converter (WEC) devices. WECs, compared to FOWT, are less mature technologies as there is a general lack of design convergence nor a standard layout. This paper investigates the ca-pabilities of a new hybrid concept developed at Politecnico di Torino, which in-tegrates a FOWT with three point absorber WECs, such WECs are integrated into the floating structure and are fundamental to obtaining the desired hydrostatic and dynamic stability. The in-house hydrostatic stability tool and the time domain model MOST are used to analyse the hybrid system motions performances with two modes: WEC activated or blocked; in this way, this paper purports to criti-cally discuss differences and advantages of the hybrid WEC-activated solution with respect to rigid floating substructures. The WEC-activated scenario outper-forms the blocked configuration, with a 12% reduction of the nacelle accelera-Pubblicazioni consigliate
