Textbook in PDF format This book provides an in-depth examination of the advanced computational and mathematical techniques crucial for the development and optimization of Wave Energy Converter (WEC) systems. As global warming and climate change continue to impact ocean engineering, the need for sustainable and renewable energy sources becomes increasingly urgent. Wave energy, with its vast and largely untapped potential, stands out as a key player in clean power generation. This volume serves as a focal point in marine renewable energies, aligning with the Sustainable Development Goals (SDG-14)
