Abstract: Fouling is the attachment and development of unwanted material on artificial surfaces immersed in seawater. The existence of fouling material leads to many economic and ecological problems in the seabed environment. Over the last 10 years, at least 30 bridges have collapsed in China because of the increase of biofouling thickness. It is important to do regular checks on bridges. An underwater check is now a common method throughout the world. Frogmen will dive underwater with tools to carry out the check. Remotely operated vehicles (ROVs) are essential tools for providing safe access underwater. In this study, underwater ROV is used as the platform to realize the cleaning of underwater structures based on cavitation jet cleaning technology.

This paper mainly deals with the simulation of jets and the experiment of cleaning. The authors focus on the application of jet cavitation technology to the ROV. I understand the importance of the subject and recognize their efforts.
