This invention provides a method for keeping a structure such as a vessel, at least part of which is submerged, from being adhered to by aquatic organisms. In the method, the submerged part of the structure is covered up with a specific non-woven fabric. The non-woven fabric preferably has such a METSUKE value that each of the gaps between the fibers has an area of 1-60 mm , wherein the &ldquo;METSUKE&rdquo; means the weight of the fibers for one square meter of the non-woven fabric. The fabric typically has less than 1 mm thick.

Method for keeping a submerged structure from being adhered to by aquatic organisms

The present invention provides a method of preventing adhesion of aquatic organisms on structures in the water such as ships. In the method, the underwater part of a structure in the water is covered up with the sheet. The sheet is made of a polyolefin and less than 1 mm thick, and has apertures each of which has a surface area of 1 to 60 mm,, the surface area in total of the apertures occupying 20 to 80% of the entire surface area of the sheet. The sheet has a tensile strength of 15 to 37% as measured under JIS L1096A and a tear strength of 3 to 9 kg as measured under JIS L1096A-1.
