The urgency of electricity demand and environmentally friendly power generator made ocean wave energy as one many renewable energies that could be implemented in Indonesia because its coastlines have the enough to generate locally regionally. This research is mainly discussing model's capability based on various height period. harvester model laboratory with 1:16 scale, so other variable compon...

Free surface modeling plays an important role in some ocean structures design, especially in Oscillating Water Column (OWC) devices. Boundary element method (BEM) is a suitable method for free surface modeling due to its simplicity, quick solving, and low data storage requirement. In this paper, BEM was used for free surface modeling in OWC chamber and out of it. Linear kinematic and dynamic bo...

In this paper, we studied the territorial, technical, and economic conditions for potential installation of a wave energy converter plant (WEC) connected to small power grid island El Hierro (Canary Islands). To define best location, non-directional gross at selected points was computed from long series data deep-water waves, propagated up coast using coefficients refraction shoaling calculated...

As a system using a conventional unidirectional air turbine in oscillating water column (OWC) based on a wave energy plant, a twin unidirectional impulse turbine topology has been suggested in previous studies. However, the average efficiency of the suggested twin turbine is considerably lower than that of a conventional unidirectional turbine in this topology because reciprocating air flow can...

The Galway Bay wave energy test site promises to be a vital resource for wave energy researchers and developers. As part of the development of this site, a floating power system is being developed to provide power and data acquisition capabilities, including its function as a local grid connection, allowing for the connection of up to three wave energy converter devices. This work shows results...

The conventional boundary integral equation for the solutions of linear wave-body interactions is extended to include the radiation solutions due to oscillatory pressures applied on the free surface. Coupled with the constraints which determine the pressure, the extended integral equation is applicable to various problems where a part of the bodies contains the free surface with oscillatory pre...

In this work we study analytically and numerically the performance of the mean heave motion of an OWC coupled with the governing equation of the spreading ocean waves due to the wide variation in an open parabolic channel with constant depth. This paper considers that the ocean wave propagation is under the assumption of a shallow flow condition. In order to verify the effect of the waves in th...
