Relevance of Hull BiofoulingRelevance of Hull Biofouling• Shipping identified as a major vector of organism
transfers on a global scale
• Bias in ecological research toward ballast-mediated transfers
• Very little data exist on hull biofouling
• Hull fouling transfer of organisms has been historically important

Biofouling is influenced byBiofouling is influenced by
• Design and construction, particularly the number, location and design of niche areas
• Operating profile
• Places visited and trading routes
• Maintenance history

The Biofouling Management Plan
Should be specific to each ship and kept with documentation. Should address:•Details of AFS & operational practices/treatments used, including those for niche areas•Hull locations susceptible to biofouling, schedule of planned inspections, repairs, maintenance and renewal of AFS•Details of the recommended operating conditions and practices suitable for the chosen AFS •Details relevant for the safety of the crew including details of the AFS

Biofouling Record Book
Should record details of all inspection and biofouling management measures undertaken. Includes:•Details of AFS and operational practices used, where/when installed, areas coated, maintenance, etc.•Dates/locations of dry dockings/slippings and any measures taken to remove biofouling or renew/repair AFS•Dates/locations of in-water inspections, results, corr. actions•Dates/details of inspections of internal sea water cooling systems•Details of when ship operated outside of its normal profile, including layup or long periods of inactivity

AFS Installation & Maintenance
AFS and operational practices are the primary means of BF prevention and control for the hull and niche areas. Guidelines provide:•Factors to consider when choosing an AFS and for installing, reinstalling or repairing the AFS (such as surface preps and care for sea chests).

Procedures for Maintenance and Recycling Facilities
• Capture biological material removed• Treat all biological material removed• Schedule arrivals to/departures from facilities
to minimize risks• Remove all fouling while in dry dock
