Project Organization

NEPTUNE will tackle the above challenges by means of synergic theoretical, numerical and experimental approaches performed by the three Research Units (RUs): Università Politecnica delle Marche (UNIVPM), Università di Firenze (UNIFI), and Università del Salento (UNISALENTO). The key for the success of the project is the interaction among the complementary competencies and resources of the three RUs. For a more effective implementation of the Project, the activities are structured in two Work Packages, WP1 and WP2, which will be fully interactive.

Structure of the NEPTUNE project

WP1 activities will be based on a strong collaboration between the UNIVPM structural mechanics and hydraulics groups and the UNIFI computational group

In T1.1, UNIVPM will analyze the dynamical behavior of the FOWT due to hydro-aeroelastic actions in the rigid-flexible multi-body model framework, considering the geometrical nonlinearities of blades and tower.

In T1.2, UNIFI will develop a new nonlinear computational approach for the platform and mooring lines fluid-structure interaction problem. The mid-fidelity model will have the ability to accurately account for the nonlinear cable dynamics in fully nonlinear water waves using highly efficient computational methods. The UNIVPM hydraulic group will develop the high-fidelity CFD-based model for fully nonlinear and full-scale numerical simulations of the floating support system.

WP2 activities will involve the UNISALENTO hydraulics group

in T2.1, an extensive experimental investigation on a down-scaled TLP-type floating platform with wind turbine will be tested at UNISALENTO to investigate the dynamics of the FOWT subjected to nonlinear cylindrical waves and wind loads.

Experimental observations will be used to broaden the exploration of the design parameters and to produce the NEPTUNE-IDG, the experimental open-access database to gather modelling techniques required for the design stages and to support theoretical and numerical model benchmarks developed in WP1.
