Application of Ultrasonic Cavitation in Ship and Marine Engineering

Abstract

Biofouling on ships and offshore structures has always been a difficult problem to solve, which not only jeopardizes the structural strength but also brings great economic losses. Ultrasonic cavitation is expected to solve this problem due to its characteristics of no damage to structures and no pollution. Starting from the phenomenon and mechanism of ultrasonic cleaning, this paper introduces the application of ultrasonic cavitation in ship, pipeline and oil cleaning as well as ballast water treatment. By reviewing the existing studies, limitations such as insufficient ultrasonic parameter studies, lack of uniform cleanliness standards, and insufficient cavitation studies are summarized to provide traceable research ideas for improving ultrasonic cavitation technology and to guide the expansion and improvement of its applications.
