Advisor: Craig Hil. 1 computer file (PDF); vii, 61 pages.This project assesses the feasibility of small-scale wave energy extraction from Lake Superior, characterized by its vast expanse and high frequency wave conditions. The research aims to evaluate the power performance of a heaving-point-absorber wave energy converter (WEC) using 15 years of historical wave observation data from NDBC 45006 located in western Lake Superior. Results aim to determine the viability of deploying similar WECs in the Great Lakes region and their potential contribution to the blue economy and marine renewable energy sector.This investigation involves the comprehensive simulation of the power generation capabilities of a point absorber WEC, specifically tailored to the wave conditions typical in western Lake Superior. To accomplish this, frequency domain modeling established WEC hydrodynamic coefficients and provided essential insights into the system's behavior in various sea states where the most common sea states were wave heights up to 1m with wave periods between 3-5 seconds, accounting for nearly 65.5% of all observations. Subsequently, through time domain analysis coupled with a hydraulic power take-off system, the WEC system's response and power output are estimated using the hydrodynamic coefficients data in the WEC-Sim software, designed to model the dynamic response of multi-body floating systems in various sea states. The power performance of the WEC resulted in an annual average electrical power output of 6.6 MWh, showcasing the feasibility of implementing small-scale WECs in Lake Superior. Additionally, the research identifies and discusses areas that require further investigation. These findings emphasize the potential of harnessing wave energy from Lake Superior, highlighting its role in marine renewable energy development and the blue economy. This includes powering remote oceanographic sensors and observation systems, establishing AUV recharging stations, and supporting aquaculture farms. The study also underscores the importance of continued research to advance our understanding of wave energy conversion within the Great Lakes context.enThesis or Dissertation
