Overtopping Breakwater for Energy Conversion (OBREC) is a new integration design concept with multifunctional abilities. The concept used structure sharing cost strategy between Wave Energy Converter (WEC) and traditional breakwater with the aims of energy capture and protection purposes. A prototype of the OBREC device was developed in Italy in 2017 and showed unsuitable output for mild wave conditions. Thus, several studies have been conducted to increase the hydraulic performance of OBREC, particularly by improving their geometries. The latest finding identified that the Cubic ramp geometry had given a promising result in increasing their effectiveness. Nevertheless, a comprehensive study of Cubic shapes on wave behaviour variations is still limited. Therefore, this study will comprehensively investigate the effect of environmental variation over the cubic and linear (as a basis) ramp shapes. Physical experimental methods were used in this study by comparing the hydraulic and power performances of both shapes to be implemented in Malaysia waters. The result indicates that cubic has higher performances than the linear shape for almost all environmental conditions. However, OBREC application in Malaysia requires support from other renewable energy sources, especially during non-monsoon season.

Abstract

Overtopping Breakwater for Energy Conversion (OBREC) is a new integration design concept with multifunctional abilities. The concept used structure sharing cost strategy between Wave Energy Converter (WEC) and traditional breakwater with the aims of energy capture and protection purposes. A prototype of the OBREC device was developed in Italy in 2017 and showed unsuitable output for mild wave conditions. Thus, several studies have been conducted to increase the hydraulic performance of OBREC, particularly by improving their geometries. The latest finding identified that the Cubic ramp geometry had given a promising result in increasing their effectiveness. Nevertheless, a comprehensive study of Cubic shapes on wave behaviour variations is still limited. Therefore, this study will comprehensively investigate the effect of environmental variation over the cubic and linear (as a basis) ramp shapes. Physical experimental methods were used in this study by comparing the hydraulic and power performances of both shapes to be implemented in Malaysia waters. The result indicates that cubic has higher performances than the linear shape for almost all environmental conditions. However, OBREC application in Malaysia requires support from other renewable energy sources, especially during non-monsoon season.
