   New ship being prepared for launch, showing fresh anti-fouling paint Ship hull being cleaned of fouling in drydock. Anti-fouling paint is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth of and facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability.

3. Biofouling - Wikipedia

   en.wikipedia.org/wiki/Biofouling

   These coatings are usually based on organic polymers. [20] There are two classes of non-toxic anti-fouling coatings. The most common class relies on low friction and low surface energies. Low surface energies result in hydrophobic surfaces. These coatings create a smooth surface, which can prevent attachment of larger microorganisms.

4. Copper sheathing - Wikipedia

   en.wikipedia.org/wiki/Copper_sheathing

   The use of copper sheathing was first suggested by Charles Perry in 1708, though it was rejected by the Navy Board on grounds of high cost and perceived maintenance difficulties. The first experiments with copper sheathing were made in the late 1750s: the bottoms and sides of several ships' keels and false keels were sheathed with copper plates ...

5. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Galvanized coatings are quite durable in most environments because they combine the barrier properties of a coating with some of the benefits of cathodic protection. [44] If the zinc coating is scratched or otherwise locally damaged and steel is exposed, the surrounding areas of zinc coating form a galvanic cell with the exposed steel and ...

6. Corrosion in ballast tanks - Wikipedia

   en.wikipedia.org/wiki/Corrosion_in_ballast_tanks

   Many maritime accidents have been caused by corrosion, and this has led to stringent regulations concerning protective coatings for ballast tanks. The Coating Performance Standard for Ballast Tank Coatings (PSPC), became effective in 2008. It specifies how protective coatings should be applied during vessel construction with the intention of ...
