Conceptual Design of OWC Wave Energy Converters Combined With Breakwater Structures

TL;DR: In this article, the options of integrating oscillating water column (OWC) with different kinds of breakwaters like the perforated or non-perforated caisson breakwater, and non-gravity piled and floating types.
Abstract: Ocean wave energy is one of several renewable sources of energy found in the ocean. The energy in the oscillatory ocean waves can be used to drive a machinery that converts the energy to other forms. Depending on the type and their location with respect the coast and offshore, a number of devices have been and are being developed to extract the wave energy for conversion into electricity. The most common devices are referred to as the oscillating water column (OWC), hinged contour device, buoyant moored device, hinged flap and overtopping device. Particularly popular are OWCs and moored floating bodies. The idea of integrating breakwater and wave energy converters emerged in the Indian wave energy program. Graw (1996) discussed this idea and pointed out the advantage of shared costs between the breakwater and the wave energy device. Because long waves are usually experience stronger reflection at coasts and breakwaters, they provide good conditions for the operation wave energy devices which work efficiently when the reflection is high. There are examples that OWC devices have been installed in water as shallow as 3 m. This paper reviews the options of integrating OWCs with different kinds of breakwaters like the perforated or non-perforated caisson breakwater, and non-gravity piled and floating types. The purpose of each of the concepts will also be highlighted.Copyright © 2010 by ASME

TL;DR: In this paper, the potential of using the power generated by waves as a natural energy resource and considering the power transfer systems needed to do this, and looks at the environmental impacts.
Abstract: Wave energy, together with other renewable energy resources is expected to provide a small but significant proportion of future energy requirements without adding to pollution and global warming. This practical and concise reference considers alternative application methods, explains the concepts behind wave energy conversion and investigates wave power activities across the globe. It explores the potential of using the power generated by waves as a natural energy resource and considers the power transfer systems needed to do this, and looks at the environmental impacts.

TL;DR: In this article, different types of breakwaters are introduced and their historical development is described in order to understand the advantages and disadvantages associated with each type of breakwater and the failures of the breakwaters.
Abstract: In this book, different types of breakwaters are introduced and their historical development is described in order to understand the advantages and disadvantages associated with each type of breakwater. The failures of breakwaters are then discussed to demonstrate crucial points in their stability design. Finally, the design methods used for vertical are explained including a new design concept of performance design for vertical breakwaters. Since the design methodology for rubble mound breakwaters has been addressed in many textbooks, the design of vertical breakwaters will be concentrated on here.
