INTRODUCTION Accurately assessing potential far-field environmental impacts due to wave energy converter (WEC) arrays is needed for commercialization of wave energy. One of the barriers to development is how to assess environmental concerns related to the potential effects these arrays will have on the nearand farfield wave climate. In order for projects in the United States to be approved, reg...

The time-average wave power that is absorbed from an incident wave by means of a wave-energy conversion (WEC) unit, or by an array of WEC units-i.e. oscillating immersed bodies and/or oscillating water columns (OWCs)-may be mathematically expressed in terms of the WEC units' complex oscillation amplitudes, or in terms of the generated outgoing (diffracted plus radiated) waves, or alternatively,...

Abstract Wave energy converters (WEC) have been researched extensively to harvest large amounts of untapped ocean renewable energy. Floating-type point absorbers are a type WEC that converts the wave electrical energy, by utilizing relative motion multi-body system mainly consisting floating section and reaction section. The design floating-type is not straightforward needs special attention un...

Abstract Wave energy converters (WECs) are built to extract wave energy. However, this kind of device is still expensive for commercial utilization. To cut down the cost WECs by sharing construction with breakwaters, an integrated cylindrical WEC-type breakwater system that includes a WEC array in front very long proposed and attenuate incident waves. This paper aims optimize performance system...

Biomimetics and creatures could contribute to novel design inspiration for wave energy converters, as we have seen numerous examples in applications of other branches engineering. However, the issue how obtain valuable biological entities, or bionic cases, that produce designs, may be challenging designers converters (WECs). This study carries out preliminary research on acquisition entities de...

WEC-Sim (Wave Energy Converter Simulator) is an open-source code for simulating wave energy converters, which has been actively developed and applied to simulate a wide variety of device archetypes, become popular tool since its release. This paper reviewed the development efforts usage WEC-Sim. The publications considered in this study have broken down into six topic areas, namely feature deve...

Mathematical analysis is an essential tool for the successful development and operation of wave energy converters (WECs). Mathematical models of moorings systems are therefore a requisite in the overall techno-economic design and operation of floating WECs. Mooring models (MMs) can be applied to a range of areas, such as WEC simulation, performance evaluation and optimisation, control design an...

Oscillating Water Column (OWC) is one the most well-known wave energy converter (WEC). Typically, OWCs are installed in rocky shores or custom-built breakwaters. However, since profile more favorable an open sea, it can also be a point absorber order to increase extraction. Thi...

The Wavestar Wave Energy Converter (WEC) is a multiple absorber concept, consisting of 20 hemisphere shaped floats attached to a single platform. The heart of the Wavestar WEC is the Power Take-Off (PTO) system, converting the wave induced motion of the floats into a steady power output to the grid. In the present work, a PTO based on a novel discrete displacement fluid power technology is expl...

We elucidate the effect of non-extracting reflectors on performance wave energy converter (WEC) arrays. consider an infinitely periodic row converters parallel to discrete axisymmetric (C-R arrays), and we study how spatial configuration affects extraction. Using a multiple-scattering algorithm for linear wave-array interactions, conduct series simulations C-R arrays range parameters, wavenumbe...
