The oscillating-water-column (OWC) spar-buoy is a type of wave energy converter that may exhibit undesirable large roll and pitch amplitudes caused by dynamic instability induced parametric resonance. occurrence this phenomenon not only reduces the power extraction but significantly increases structural loads on buoy, turbine rotor mooring system. paper compares resonance behaviour two configur...

Light detection and ranging (LiDAR) optical wireless communication (OWC) are in high demand rapidly developing owing to the explosive growth of smart systems that require automotive mobile devices. Optical phased arrays (OPA) have become a key technology LiDAR OWC their nonmechanical beam steering capabilities. However, using separate platforms one system creates problems, such as spectrum cong...

Abstract Systems based on the OWC principle allow to convert sea-wave energy into electrical energy. The potential contained in wave motion is first converted pneumatic of a bi-directional airflow, generated by oscillatory displacement column water inside chamber. Then, an air turbine, such as Wells placed at top chamber, converts mechanical its shaft, which can be coupled electric motor produc...

Air-cushion-assisted platforms (ACAPs) are floating supported by both buoyancy pontoon and air cushion, which have merits of wave bending moment reduction, better stability, hydrodynamic performance. However, there is barely a concise method that can quickly predict the motion response ACAPs. In this paper, simplified panel (sPM) was presented for evaluating hydrodynamics The sPM extends conven...

The Indonesian Ocean Energy Association has ratified the potential for ocean wave energy in Indonesia with a theoretical of 141,472 Megawatts. Unfortunately, this vast not yet been utilized optimally seas. technology developed rapidly various countries worldwide. One most famous power generation technologies is Oscillating Water Column (OWC), which utilizes airflow from waves oscillating moveme...

Light-fidelity (LiFi) is a fully-networked bidirectional optical wireless communication (OWC) technology that considered as promising solution for high-speed indoor connectivity. Unlike in conventional radio frequency systems, the OWC channel not isotropic, meaning device orientation affects gain significantly. However, due to lack of proper models LiFi many studies have assumed receiver vertic...

This study is focused on the wave energy converter of an oscillating water column (OWC) system that integrated with a jacket type infrastructure applied for offshore wind turbine system. In this way, electricity generation by both power and can be conducted simultaneously to maximize utilization sustainable energy. A numerical analysis was performed in research model simulate airflow response e...
