Il presente documento tecnico descrive le fasi di progettazione, costruzione e installazione del primo prototipo di turbina eolica galleggiante nel Mediterraneo, presso il MaRELab (laboratorio a mare) antistante il porto di Napoli. Una delle innovazioni del progetto è rappresentata dall'utilizzo di una piattaforma galleggiante, prima al mondo, che utilizza la tecnologia a pendolo Hexafloat, brevettato da Saipem. Grazie a questo progetto innovativo è stato possibile testare per la prima volta delle nuove soluzioni tecnologiche innovative, come l'utilizzo di cavi in fibra sintetica per gli ancoraggi e per i tiranti del contrappeso.

In this paper is presented a report of the status of the sensors after the stress test measurements carried out on a propeller of an outboard engine, preceded by the installation ehase for the most correct understanding of the anomalies and malfunctions occurred in the experimental phase, within the CSP Fluid-Techno project.

In this report the data of the tests on scaled fuselages with dynamic pitch performed at CNR-INM (Institute of Marine Engineering), former CNR-INSEAN, on scaled fuselage models are presented. The report provides details on the test models, their design and built, on the experimental setup and the test data. The tests with dynamic pitch enable to estimate the unsteady pressures and loads acting on the fuselage as a consequence of an enforced pitch motion. The data allow to assess the capability of the computational tools to predict the changes in the loading associated with the dynamic pitch variation, which is the forcing terms of the equations of body motion. In turn, this is an important step to ensure an accurate reconstruction of the aircraft dynamics. Moreover, the effect of the interaction with waves during the ditching phase is analysed in both heading and following sea conditions

This technical report concerns with experimental investigations carried-out at the CNR-INSEAN towing tank on oscillating 3D wings. The experimental campaign is aimed at characterizing the behavior of 3D translating and pitching wings, with different sectional shapes, in terms of unsteady hydrodynamic loads due to selected harmonic pitching laws. The main interest of the activity is on the dynamic stall onset that, if present, changes the hydrodynamic response of the wing respect to the stationary operating condition. For this reason, data analysis highlights the differences between steady and unsteady forces to define the operating conditions boundaries for each wing-type herein investigated. This document represents the Project Deliverable 2.0 in fulfillment to tasks 4-7 of Contract 05CT12.
