The project LARGE MULTIPURPOSE PLATFORMS FOR EXPLOITING RENEWABLE ENERGY IN OPEN SEAS (PLENOSE) aims at establishing a multi-disciplinary network between European, North American and Indian institutes.

From the perspective of an exchange of competencies, the objective of PLENOSE is to share the expertise of the partners in the fields of Marine Engineering, Structural Dynamics, Reliability Assessment, Random Processes and the necessary skills for performing experiments in artificial and in natural basins. The scientific goal of the PLENOSE project is to define and validate a technique for the design of artificial islands consisting of floating or fixed structures, with the well defined purpose of exploiting renewable energies in open seas. The multipurpose ‘energy island’ may produce energy from sun, wind and waves, with several advantages.

For example, the global downtime is reduced if different sources of renewable energy are considered: if wind does not blow, electrical power may be produced from waves (with swells) and/or sun, and so on. At this purpose, pertinent dynamical models and adequate experimental models are exploited in order to disseminate the problems occurring at the design stage. Novel methodologies in the field of stochastic dynamics (e.g. Wiener Path Integrals, Wavelets based statistical linearization) are analysed for performing random vibration analysis.

Moreover, innovative wave energy converters, based on the principle of the Oscillating Water Column, are investigated for maximizing the harvesting capability of the plant.
