DESIGN, MANUFACTURING, AND TESTING OF OFFSHORE OSCILLATING WATER COLUMN

Abstract

This report focuses on the comprehensive design, manufacturing, and testing of an offshore oscillating water column (OWC) system aimed at harnessing the power of ocean waves for electricity generation. The OWC system operates by exploiting the pressure fluctuations inherent in ocean waves, converting them into a continuous airflow that drives a turbine to produce electricity. The design phase of the OWC system encompasses meticulous selection of appropriate materials, structural design considerations, and accurate modeling of its performance characteristics. Meanwhile, the manufacturing process entails the fabrication and assembly of various components, including the wave chamber, turbine, and generator. The testing phase encompasses a series of rigorous assessments, encompassing laboratory testing, numerical simulations, and field testing. The objective of this report is to contribute to the advancement of offshore OWC systems while shedding light on the challenges and opportunities inherent in their design, manufacturing, and testing. By offering practical insights into each aspect of the OWC system's life cycle, this work aims to address the current gaps in knowledge and facilitate the development of efficient and cost-effective solutions for electricity generation from ocean waves. The offshore OWC system described in this report represents a promising avenue for generating electricity from a sustainable and renewable source. With the escalating demand for clean energy sources, this technology has the potential to make a significant contribution to the global energy transition. By utilizing the immense power of ocean waves, this system offers a practical and scalable solution for meeting electricity needs while reducing reliance on fossil fuels. iv To validate the OWC system's performance, a comprehensive testing program is undertaken. Laboratory testing enables controlled experiments to evaluate the system's response under varying wave conditions, providing valuable data for performance analysis and refinement. Numerical simulations complement the experimental findings, offering a deeper understanding of fluid dynamics and aiding in the optimization of the system's design.
