Résumé : AbstractStructural optimization of offshore wind turbines is very tough task due to complexity of the problem. The present paper reviews offshore wind turbine structures, one of the more popular forms of renewable energy, including attractions and challenges of electric power generation through onshore and offshore resources. Offshore wind-power generation presents many engineering challenges including: limited guidelines available for analysis and design of foundation/support structures; inadequate logistics for construction/fabrication; and comparatively expensive operation and maintenance costs, which combined result in current cost of energy approximately double that for onshore wind-power generation. Different offshore foundation options are deliberated in terms of general layout, loading characteristics and related fundamental natural frequency.
