Antifouling coatings are a benefit to the environment because they reduce vessel drag which can increase fuel usage by as much as 86% and reduce the hull transport of nonindigenous species which may account for up to 70% of invertebrate invasive species in coastal waters.  Copper-based antifouling coatings are used on over 90% of vessels in the world that have biofouling control coatings on their hulls.

Antifouling coatings are a benefit to the environment because they reduce vessel drag which can increase fuel usage by as much as 86% and reduce the hull transport of nonindigenous species which may account for up to 70% of invertebrate invasive species in coastal waters.  Copper-based antifouling coatings are used on over 90% of vessels in the world that have biofouling control coatings on their hulls.  Scientific evaluation supports the use of copper in this application because it has limited toxicity to non-target organisms away from the vessel hull due to the capacity of water and sediments to bind the copper in a form that isn’t bioavailable to organisms.  However, additional regulations and constant reevaluation of the use and management of all biocides continue to put pressure on any human exposure or environmental input.  Biocidal antifouling and biocide free coatings are constantly being introduced as alternatives to copper.  Working with regulatory agencies and understanding the safety of copper and its alternatives is imperative to successfully maintaining an economically healthy and environmentally sound biofouling control industry.
