Abstract

Increased clean energy needs have spiked interest in harvesting wind energy off the coast of New England. The region experiences drastic changes in weather patterns from season to season, significantly impacting strength, fatigue, and life of offshore structures. In this study, current model offshore win d turbine structures were designed and analyzed to best handle New England’s dynamic environmental loads. Three general structure types were designed and analyzed using finite element analysis and ANSYS software. Structures included the four legged jacket monopile, three legged jacket monopile, and three legged twisted jacket monopile. Research validation was performed, proving accuracy of FEA and ANSYS results. Final testing of designs resulted in a best fit structure based on fatigue and strength analysis, maintenance and construction costs, and environmental impacts.
