  1. 2011 Guidelines for the Control and Management of Ships’ Biofouling to Minimize the Transfer of Invasive Aquatic Species James River Reserve Fleet

  2. Relevance 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 • Photo by Smithsonian Environmental Research Center, http://www.serc.si.edu • Photos by Aquatic Bioinvasion Research and Policy Insitiute, Portland State University, http://www.clr.pdx.edu

  3. IMO Activity • MEPC 56 (2007) – high priority item assigned for inclusion in the work programme of BLG • BLG 13 (2009) - agrees to develop Guidelines for the control and management of ships’ biofouling to minimize the transfer of invasive aquatic species • Adopted 15 July 2011, Resolution MEPC.207(62)

  4. What is Biofouling?

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

  6. Niche Areas(overboard discharge pipes)

  7. Niche Areas(intakes)

  8. Niche Areas(Dry docking support strips)

  9. Guidelines Sections • Biofouling Management Plan • Measures to be undertaken on the ship • Record Book • Records of practices implemented • AFS Installation and Maintenance • Procedures for Ship Maintenance & Recycling Facilities • In-water Inspection and Cleaning • Design and Construction Considerations • Dissemination of Information • Training and Education (masters and crew)

  10. 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

  11. 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

  12. 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).

  13. 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

  18. In-Water Cleaning of the Hull

  19. Pre-Cleaning Hull Status(frame 14 on hull) Waterline Keel

  20. Post-Cleaning(Frame 14)

  21. Effects of Hull Cleaning • Number of Species per sample (mean ± SE) • Abundance per sample (mean ± SE) • Percentage Cover (mean ± SE)

  22. Dry docking in SF Bay

  23. Sampling Niche Areas

  24. Where do we go from here? Develop ISO standards to be developed to assist industry in implementing elements of the Guidelines • In-water survey methods to determine effectiveness of husbandry actions? • Other?
