Biofouling Management

  • Overview

Biofouling is the undesired growth of marine algae, invertebrates, or other marine microorganisms on a submerged structure, primarily ship hulls but also on offshore platforms and marine renewable energy structures.  

The transport of alien species to new habitats where they may monopolise, outcompete native species and create changes to local ecosystems and food webs is harmful to marine communities.  

The biofouling of ships is also detrimental to ship operations, increasing drag, boosting fuel requirements, and reducing efficiency and can impact other structures such as tidal turbines, increasing operational and maintenance costs. 

Techniques to reduce invasions via biofouling include removal of species and additional mechanisms to protect ships such as anti-fouling paints and treatments. 

The group provides a platform of knowledge exchange and technical expertise on these issues to ensure shipping and other maritime industries can continue to underpin trade, security, and economic development with minimal environmental impact, both in the immediate and long term.
