Techniques are described which have been employed to develop detailed, quantitive estimates of the available ocean wave energy flux. A summary of results for a region of particular interest to potential U.S. developers of wave energy systems — the U.S. Northwest Pacific Coast — is also presented. Comparisons with results of other studies are made. In addition, a method for predicting the amount of mechanical energy captured by a conversion device, based on a frequency domain technique, is presented. Results are predicted for an articulated, contour following raft deployed in deep, open water west of the mouth of the Columbia River.

Generation Unit

Energy resources of offshore wind and ocean wave are clean, renewable and abundant. Various technologies have been developed to utilize the two kinds of energy separately. This paper presents the principle of an integrated generation unit for offshore wind power and ocean wave energy. The principle of the unit includes that: The wind rotor with retractable blades and the 3-DOF (degrees of freedom) mechanism with the hemispherical oscillating body are used to collect the irregular wind and wave power, respectively; The energy conversion devices (ECDs) are utilized to convert mechanical energy from both the wind rotor and the 3-DOF mechanism into hydraulic energy; The hydraulic energy is used to drive the hydraulic motors and electrical generators to produce electricity. Some analyses and experiments of the unit is conducted.

The Waves

Ocean energy is a precious pearl. However, in the exploitation of the sea of people, the available development of ocean wave energy method is too simple and the structure of the device is relatively complex. This paper examines the analysis for the direction of the waves along the coast, and designed a dual-channel ocean wave energy generation device as well as having made a detailed description of its structure and concrete working principle. The ingenious engineering design of the device can continuously generate electricity. As the waves of high and low tides will produce mechanical energy to drive the rotation of the impeller, the improved design in this paper make full use of this principle so that can produce a steady stream of electricity. Due to the inherent advantages of this device, it has great room for improvement and broad application prospects.

Main Components

Ocean waves are huge, large untapped energy resources and the potential for extracting energy from waves is considerable. Ocean wave energy can play a dynamic role for producing electricity as fresh source of renewable energy to the off-grid power connection in remote areas. There are number of research work going across and around the coastlineto generate electrical energy from the ocean waves. Wave energy conversion technologies are important and lead to more research work in future.Wave energy converters converts the mechanical energy obtained from ocean waves to electricity. Researches in this area are driven for the need to meet demand in electricity but it is relatively immature compared to other renewable energy technologies. This proposed paper aims to develop a prototype that can utilize the wave energy to produce electricity. Wave energy generator has been developed and the results are analysed for different specifications of converter and also presented. From the experimental setup it is assured that slowly varying power generation is obtained from ocean wave. This paper also comprises working and main components of the system.
