Abstract

This study evaluates the mooring systems of wave energy converters (WECs), particularly focusing on the tensile loads of a single buoy and a novel hinged multi-buoy system, the M4, developed by the University of Manchester. Using OrcaFlex software, the research validates a numerical model through a comparison with experimental results from the University of Plymouth’s COAST Laboratory. This process assesses OrcaFlex’s ability to simulate complex floating structures under various conditions. Key findings reveal that discrepancies between numerical and experimental data increase under severe wave conditions and when multiple constrained floating bodies are involved. The study identifies critical factors contributing to these discrepancies, enhancing both experimental and numerical methodologies. This research substantiates the numerical model’s accuracy for the M4 WEC, contributing significantly to advancing efficient and reliable wave energy technologies.
