Abstract
Biofouling, the accumulation of aquatic organisms on submerged structures, poses significant challenges to offshore operations by obstructing water flow and accelerating corrosion. Traditional mitigation methods are often environmentally harmful and demand frequent maintenance. This study explores the use of high-power ultrasound transducers as an eco-friendly solution for biofouling prevention in sea subaquatic structures. Numerical simulations and field experimental tests were performed. Results showed effective biofouling mitigation through ultrasonic pressure and microvibrations on the sea chest structures.
