Abstract

This report is part of a research into the development of a novel Wave Energy Converter (WEC) called the Ocean Grazer. The WEC uses an array of interconnected floaters in a so called floater blanket to harvest wave energy at open sea. The amount of energy that is extracted from the wave is highly dependent on the damping force. The damping force that each damper exerts on the incoming waves can be separately adapted for each floater, in order to improve the performance of the floater blanket. Considering that each floater has 8 possible damping settings, and that a floater blanket of 100 floaters is considered for this report, this results in 2*1090 possible configurations. For analysis of the performance of the floater blanket at different configurations a frequency-domain MATLAB model is created by the Ocean Grazer team. This model uses a configuration of damping coefficients as its input, and returns information about e.g. the capture factor (the relation between the amount of power in the incoming wave and the extracted power). With the current available computational power it is however still impossible to run each configuration through the MATLAB-model in order to find the most appropriate setting.
