BALLAST WATER, WHAT DOES IT CONTAIN ? 10 billion tonnes of ballast/year carries > 7000 species at any one time Some of the organisms are harmful in their new environment and / or invasive
WHY DO WE NEED TO STOP THEM ? ? Ecological reasons Economical reasons Human health reasons
HOW TO STOP THEM ? ? BALLAST WATER MANAGEMENT is the answer
IMO response to BALLAST WATER issue: Res. A.774(18) in 1993, revoked by Res. A.868(201) in 1997 Ballast Water Management Convention, adopted 2004(needs 30 countries / 35 % world GT to enter into force)
HOW TO MANAGE BALLAS WATER ? NO DISCHARGE EXCHANGE ISOLATION ON-BOARD TREATMENT SEQUENTIAL FLOW THROUGH DILUTION RECEPTION FACILITIES PHYSICAL Heat Ultraviolet Ultrasound CHEMICAL Disinfectant Organic biocides MECHANICAL Filtration Cyclonic separation
BALLAST WATER MANAGEMENT CONVENTION Section D – Standards for ballast water management Reg. D-1: Ballast water exchange standard 95 % volymetric exchange; or 3 times pumping through the volume of each tank Section B – Management and control requirements for ships Reg. B-4: Ballast water exchange -200 nm and 200 m depth, or if not possible - 50 nm and 200 m depth, or if not possible - in areas designated by the Port State Ballast Water Exchange shall only be undertaken when safety of the ship is guaranteed

In the future: Management through ballast water treatment or alternatives
BALLAST WATER TREATMENT Section D – Standards for ballast water management Reg. D-2: Ballast water performance standard less than 10 viable organisms / tonne ≥ 50 μm; and less than 10 viable organisms / ml ≤ 50 μm and ≥ 10 μm; and indicator microbes ≤ following concentrations: - Vibrio cholera< 1 cfu /100 ml -Escherichia coli< 250 cfu /100 ml- Intestinal Enterococci< 100 cfu /100 ml
Section B – Management and control requirements for ships Reg. B-3: Ballast water management requirements
I’m sure we just discharged that crocodile OK. that definitely meansTHE END
