[en] Currently, ocean plastic pollution has a big impact on both marine and human health. Thanks to the diversity in renewable energies on boats, diverse de-pollution energy-neutral solutions are envisaged. The aim of this work is to evaluate the relevance of installing horizontal axis wind turbines HAWT on a vessel, with a specific study on the SeaVax, a collecting plastic vessel. Indirectly, this objective also intends to provide the SeaVax company with additional information to the work already carried out.

To that end, the vessel’s energy consumption is assessed for three sectors : propulsion, plastic management and navigation. Moreover, the total daily energy production is evaluated for four scenarios associated to two locations and two time-frames. The overall energy production is divided in two sources : photovoltaic panels (PVs) and wind turbine(s) system. All computations are completed using Excel software and data available in the literature. Based on the estimated energy production of both sources, 26 models of two wind system designs are studied, one with a fixed wind turbine and the other with two moveable wind turbines. By applying constraints to these models, the most suitable model for the SeaVax is selected.

Despite a potential overestimation of 30 % for the energy consumption relative to the propulsion and the lack of information for the navigation, the evaluated energy requirements provided the company with useful and interesting details about the distribution of the energy consumption in different sectors. The evaluation of the overall production of the vessel made it possible to highlight the disparities between the studied scenarios. Moreover, the capacity factors of the solar panels confirm the relevance of their installation. By contrast, although adapted to the SeaVax, none of the HAWT study designs is assumed as relevant.

With regard to the exploitation of wind and solar potentials, the route taken by the SeaVax vessel
represents an interesting approach to be developed under the assumption that for an additional 11 m² of PVs only one studied scenario wouldn’t produce enough to meet the energy demand. Finally, it appears that HAWT are not suitable for vessel energy production. Both in terms of production and propulsion, other tracks are to be exploited with a certain compatibility with photovoltaic panels.
