ADVANCES IN ANTIFOULING COATINGS TECHNOLOGY
Antifouling paints work largely by releasing self-polishing copolymers have harmful impact on marine environment. But the European Biocidal Products Regulation (BPR) calls into question less harmful copper-based antifouling paints. Leading companies are updating their lines to meet the upcoming deadlines.
The new regulations require that all key biocides used in antifouling yacht paints in the EU be assessed. The RYA supports the BCF’s call for those responsible for the BPR to work with their European counterparts to establish a common, appropriate and pragmatic approach to biocidal product authorisation, especially with regard to setting realistic protection goals. The combination of environmental concerns, rising costs, and technological changes has spurred the search for better solutions.
Poisoning the ocean is not the only problem posed by organisms adhering to hulls. International Maritime Organization (IMO) director Stefan Micallef explained: “The IMO has been at the forefront of the international effort to tackle the transfer of invasive aquatic species by ships. Addressing hull fouling is a crucial step in protecting marine biodiversity. The treatment of hulls to reduce fouling by aquatic organisms has the additional benefit of reducing greenhouse gas emissions, since [it also reduces] drag.”
In 2017, the IMO announced it was allocating $6.9 million to its new GloFouling Project, covering both commercial and recreational vessels. All available approaches will be examined, including improved ultrasonic waves, nanotechnology and robotic solutions.
