Antifouling: Benefits for marine protection barriers

Most people associate antifouling treatments with its use on hulls of boats and ships to reduce marine growth and maintain a smooth and slick surface so fuel efficiency and speed are kept at maximum levels. In fact, antifouling has a vast array of uses across a wide range of maritime industries from fish farming, maritime transportation to marine protection barriers such as jellyfish nets and debris booms.

Antifouling is essentially a treatment that limits the culturing and adhesion of marine growth and other marine life on to a treated surface in an aquatic environment. In practice, it suppresses the growth of marine life on antifouled surfaces to allow for a longer and more efficient term of use.

We use antifouling treatments on many of our Ecobarrier marine protection and demarcation barriers, such as jellyfish nets, swimming barriers and debris nets to prevent the build-up of marine growth on the submerged elements of the barrier. This is most often marine net or mesh.

The antifouling is applied as an additional coating to the net to provide a surface that marine growth cannot adhere to or grow on. There are two commonly used methods. The first method produces microscopic fibers on the netting that – combined with the undulating motion of the water layers – means it is extremely difficult for organisms to settle and find residence on. The second is a copper-based coating which also deters growth from the surface on the netting. Both methods are environmentally friendly and non-toxic, which is one of the most important factors to take into consideration when considering an antifouling treatment. The antifouling should be a medium type, containing 15% of Cu2O, not more, so as to be certified and more environmental friendly.

Interested in knowing why you need it and how long it lasts? Our paper also includes a case study that shows the difference between a net with and without antifouling treatment. Reach out to James at james@ecocoast.com to get all information.
