“…It was shown that the power take-off control of the OWCs had a beneficial impact on reducing the platform's responses and WT structure loads, resulting in 15% pitch motion mitigation and 6% tower base fatigue load reduction. Recently, in [175], a scaled model test campaign of a floating WT with or without the presence of OWC converters was presented. The structure, which was allowed to oscillate in a heave direction under regular wave trains, consisted of a cylindrical floater with a concentrically integrated OWC.…”

The main challenge in designing offshore renewable energy structures is to ensure their structural integrity on a life cycle basis while operating in harsh environments and, in parallel, being financially competitive and environmentally friendly concerning other types of energy systems. The Oscillating Water Column (OWC) converters are among the first energy converters to be developed and deployed into the sea due to their relative simplicity of operation and relatively small number of moving parts. This review provides an overview of the recent floating OWC prototypes and projects and the latest research developments in wave energy conversion using the oscillating water column principle. Furthermore, critical structural advances are discussed, mainly focusing on the converter’s geometry and type and its mooring system design towards amplifying the absorbed wave power.

“…The Oscillating Water Column consists of an air-filled column or collection chamber that serves to drive turbines, columns through which water moves up and down through underground channels, and turbines connected with generators [6]. Water movement the rise and fall that along with the waves of the sea cause the air to flow through the channel leading to the turbine [7].…”

Hydro energy is one of the potentials of renewable Energy in Indonesia. Indonesia has a vast sea, in the amount of 3,544,743.9 km2 making Indonesia a suitable country to utilize Oscillating Water Column (OWC) type power plants. The study was conducted to determine the effect of column diameter on the performance of OWC devices, especially in speed and dynamic pressure. There are 5 variations of the diameter of the column studied, namely 0.5 m, 0.75 m, 1 m, 1.25 m, and 1.5 m. Plus there are also variations in the wave period, namely 3s, 4s, and 5s. The result of this study is the column diameter of 0.75 m has an average speed of 0.389 m/s and a dynamic pressure of 2.676 N/m2, making it the best column diameter ratio of the five column diameter ratio options available.
