Comparison between traditional boat bottom cleaning methods and cavitation disk and scraper underwater cleaning methods

Date:2024-05-06   Visits:134


In the ocean shipping industry, ship maintenance is crucial. Cleaning the bottom of the ship is one of the important aspects of ship maintenance, which is related to the navigation safety and hull life of the ship. Traditional ship bottom cleaning methods mainly rely on manual cleaning with scrapers, wire brushes and other tools, or use ship anti-sea life systems to prevent the attachment of sea creatures. These methods are not only inefficient, but also cause certain damage to the hull, and produce chlorine and metal ions. It will also pollute the marine environment. With the development of science and technology, new underwater cleaning methods of cavitation jet cleaning plates and underwater cleaning methods of hydraulic scrapers have gradually been widely used.

The new cavitation jet cleaning plate underwater cleaning method uses cavitation jet technology to clean the bottom of the ship. This method mainly relies on the cavitation effect to generate a large number of small bubbles. When the small bubbles burst, an instantaneous high pressure and high temperature will be formed in the surrounding area, which can quickly peel off the attachments formed by marine organisms and crush the epidermal cells of the organisms, effectively inhibiting marine organisms. It adheres and grows, protects the hull, seawater pipelines and related equipment, and has the advantages of environmental protection, energy saving, and easy maintenance. The hydraulic scraper is equipped with a wire brush disk, a nylon brush disk, a blade brush disk, etc. It is driven by a gasoline engine, diesel engine or motor to clean large areas of marine life. It can be operated by a single person and is very labor-saving.

First, they can significantly improve cleaning efficiency, shorten ship docking time, and reduce operating costs. Secondly, cavitation jet cleaning will not damage the surface coating of the hull and will not destroy the anti-corrosion layer and coating on the hull surface. In addition, the cavitation jet can penetrate deep into small gaps and hidden parts of the bottom of the ship to completely remove stubborn sediments and biological attachments to ensure the quality and effect of cleaning. The most important thing is that the ship does not need to go ashore and can be cleaned in the water.

Through the introduction of traditional ship bottom cleaning methods and new cavitation jet cleaning disk and hydraulic scraper underwater cleaning methods, it can be seen that the new cavitation jet cleaning and hydraulic scraper cleaning methods have advantages in efficiency, cost, hull protection, and cleaning. It has significant advantages in terms of quality and scope of application. Therefore, in practical applications, it is recommended to use the new cavitation jet cleaning disk and hydraulic scraper underwater cleaning methods for ship bottom cleaning and maintenance to improve the efficiency and quality of ship maintenance.
