ABSTRACT

ABSTRACT

Offshore floating wind turbines (OFWTs) are gaining popularity due to their superior wind energy capture and minimal visual impact. However, traditional steel support foundations for OFWTs are plagued by corrosion issues. This article proposes the use of Fiber-Reinforced Polymer (FRP) reinforced Ultra-High Performance Concrete (UHPC) composites, referred to as FRU composites, for OFWT foundations. Durability assessment of FRU plates under simulated marine environment is conducted based on accelerated aging tests on FRU plates. Scanning electron microscope (SEM) analyses are conducted to explore the fracture surface and interface between FRP and UHPC matrix. A series of tests are conducted and the test results of the FRU elements are summarized in this article. Strength design methodologies for FRU elements under various loadings are established based on summary of existing studies. Hydrodynamic analyses and comparative studies between FRU and steel OFWTs reveal that FRU OFWTs demonstrate improved stability and reduced motion responses under combined wind-wave-current loading conditions. The successful development of FRU composites is anticipated to revolutionize the OFWT industry by offering durable and cost-effective foundation options.
