Study on the use of wave energy in port breakwaters presented on June 12th

07-06-2019
The project SE@PORTS - Sustainable Energy at Sea Ports was born in 2017, with the objective of evaluating the potential of using wave energy in port breakwaters. On June 12th, the results of this study, which was coordinated by INEGI, will be presented at the APDL, in Matosinhos, starting at 10h00. Sign up available HERE.

Besides the presentation of the projects results, the event will feature a group of international experts, who will share their experience with this type of technology. Also scheduled is the presence of Ana Paula Vitorino, Minister of the Sea of ​​the Portuguese Government.

ENHANCING THE POTENTIAL OF WAVE ENERGY

This project was born from the desire to create synergies between the renewable energy and port sectors, taking advantage of wave energy as a renewable energy source.

The effect of wind on the surface of the ocean drives the waves, whose energy can be transformed into electrical energy. However, Tiago Morais, INEGIs researcher responsible for the project, explains that it is not used on a large scale because "the existing technology has a high investment and operating cost compared to other forms of renewable energy".

To mitigate this problem, the consortium has designed and developed a hybrid system that combines existing wave energy conversion (WEC) technologies to be integrated into port breakwaters.

"The proposed solutions were designed to reduce construction, installation and maintenance costs, ensure high levels of efficiency and structural integrity, even under extreme operating conditions," says Tiago Morais. "By incorporating the advantages of each WEC and eliminating its inherent limitations, we intended to increase the overall efficiency of the system."

"This type of technology is advantageous for ports as it allows them to be integrated into port breakwaters by promoting the dissipation of wave energy, responding to the energy consumption resulting from its operation in a sustainable manner, as well as reducing carbon emissions" he adds. The project included two case studies - the Port of Leixões in Portugal and the Port of Las Palmas in Spain.

The generation of the hybrid concept, the development of numerical models to characterize the behavior of the various systems, and the manufacture of small scale models for wave tank tests, as well as the study and adaptation of the Lean Design-for-X methodology, were responsibility of INEGI.

SE@PORTS was developed by a consortium led by INEGI, with the participation of the Fórum Oceano, Faculdade de Engenharia da Universidade do Porto, IHCantabria, PLOCAN and IMDC (International Marine & Dredging Consultants).

The project was funded by OCEANERA-NET, the Portuguese Foundation for Science and Technology (FCT), Agentschap Innoveren & Ondernemen, Canary Islands Agency for Research, Innovation and Society, and Sodercan.
