A method for preventing marine biofouling of underwater structures of active marine facilities

Abstract

The invention discloses a method for preventing marine biofouling of the underwater structure of active marine facilities, which is characterized in that the implementation steps of the method are: (1) cleaning the marine organisms and other loose attachments on the underwater structure, and using Grinding with a pneumatic grinder until smooth; (2) Winding a wrapping tape soaked in solvent-free underwater antifouling paint on the surface of the treated underwater structure, and fixing the upper and lower ends with cable ties after winding; (3) Underwater antifouling Before the surface of the damaged paint dries, wrap a foamed copper alloy thin strip on the outer surface. After the winding is completed, fix the upper and lower ends with cable ties; (4) Remove the cable ties after 24 hours to complete the anti-marine biofouling construction of the underwater structure. Compared with other methods for removing or preventing marine biofouling, the method for preventing marine biofouling of underwater structures of active marine facilities has the advantages of lasting effect, economy, safety, and convenient construction.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a method for preventing marine biofouling of underwater structures of active marine facilities. Background technique [0002] There are more than 18,000 species of epiphytes and more than 600 species of epiphytes in various sea areas of the world, the most common being algae, hydra, barnacles, and oysters. Marine organisms will attach to the surface of underwater pile legs, jackets, structures, and pipelines of offshore oil platforms and other facilities, causing fouling and increasing the weight of the facilities. The attachment of marine organisms will also damage the anti-corrosion coating. Inserting the coating up to the steel will accelerate the corrosion of the steel and pose a serious threat to the safe production of the facility. At present, the methods of removing marine organisms or preventing marine biofouling are mainly divided into: physical methods, including mechanical re...

Problems solved by technology

[0003] The use of anti-fouling paint is the most convenient and effective method, but it can only be painted in a dry environment, and it is powerless for underwater facilities in service; the radiation method and chlorine gas are too dangerous and involve a lot of harm. It is difficult to implement large hazardous chemicals; the equipment involved in the electrification electrolysis method is huge and complicated, and it is difficult to realize; the mechanical method is labor-intensive and expensive to remove, and will damage the anti-corrosion coating; the effect of the ultrasonic method is difficult to confirm
