Abstract (EN):
Sea ports are highly exposed to ocean waves,
being often necessary to protect them with breakwaters and
other sheltering solutions. Also, ports are infrastructures with
substantial energy demands and major sources of air pollution
and other environmental impacts. By using renewable energy,
in particular electricity harvested from ocean waves, ports
would be able to convert some of the disadvantages associated
with the harsh ocean environment into a potential solution for
the problem of large energy demands and pollution. In fact,
many ports worldwide already started the transition to cleaner
energy sources in order to decarbonize their activities and meet
their future renewable energy targets. The high potential of
port breakwaters for the integration of Wave Energy
Converters (WECs) triggered the European SE@PORTS project
(OCEANERA-NET), which aims to assess the suitability and
viability of existing energy conversion technologies to be
integrated into such infrastructures. The present paper
introduces the preliminary design of a hybrid WEC solution
that combines the concepts of Oscilating Water Column (OWC)
and OvertoppingWave Energy Converter (OWEC).Thishybrid
WEC was developed taking into consideration the
characteristics of the north breakwater of the Port of Leixões,
Portugal, and the proposed plan for its extension. In order to
simulate the physical phenomenon behind the OWC, a waveto-wire model was developed in MATLAB SIMULINK. The
performance of the OWEC was estimated resorting to the code
WOPSIM (Wave Overtopping Simulation). Both tools were
used to assist in the optimization of the hybrid WEC design.
Some of the preliminary results are presented in this paper.
