Exploring the Impact of Sub-Sea Technology Development on the Southern Brazilian Shelf

Application of marine currents for electricity generation could offer a distinct advantage over other renewable energy sources due to the regular and predictable nature of this resource. This paper details the application of AHP (Analytical Hierarchy Process) as a possible tool to help decision makers comprehend better the environment and the impacts of the marine current turbines. Towards the usage of a tridimensional model (TELEMAC3D) the best spots for generating energy for the currents were found and then applied into the AHP. Several database were compared to minimise decision deviation. The results enhance the viability of the northern region of the Southern Brazilian Shelf (SBS) as a possible spot to harvest the energy from the currents.
