Biofouling Management Plan

International Convention for the Control and Management of Ships' Ballast Water and Sediments, 2004 (BWM Convention).

Biofouling Management Plan
In the adoption of the International Convention for the Control and Management of Ships' Ballast Water and Sediments, 2004 (BWM Convention), Member States of the International Maritime Organization (IMO) made a clear commitment to minimizing the transfer of invasive aquatic species by shipping. Studies have shown that biofouling can also be a significant vector for the transfer of invasive aquatic species. Biofouling on ships entering the waters of States may result in the establishment of invasive aquatic species which may pose threats to human, animal and plant life, economic and cultural activities and the aquatic environment.
To minimize the transfer of invasive aquatic species, ships should implement the biofouling management practices which include use of antifouling systems and operational management practices to reduce development of biofouling.
Such management practices can also improve a ship's hydrodynamic performance and can be effective tools in enhancing energy efficiency and reducing air emissions from ships.
Biofouling Management Plan shall contain:
  1. Details of the anti-fouling systems and operational practices or treatments used, including those for niche areas;
  2. Hull locations susceptible to biofouling, schedule of planned inspections, repairs, maintenance and renewal of anti-fouling systems;
  3. Details of the recommended operating conditions suitable for the chosen anti-fouling systems and operational practices;
  4. Details relevant for the safety of the crew, including details on the anti-fouling system(s) used; and
  5. Details of the documentation required to verify any treatments recorded in the Biofouling Record Book, which shall be contained in the Biofouling Management Plan.
