Invasive Species: A Global Concern Ships transport over 80% of the world s commodities, and transfer 3 to 5 billion tons of ballast water annually between oceans, all the while ballasting and discharging water during operation. Ballast water contains many marine organisms, larvae, eggs, plankton that, when introduced into a new environment, may survive and invade the local marine ecological system. It has been estimated that more than 7000 species are transported each day through ballast tanks, and that some 40 recent invasions occurred because of ballast water discharge. The International Maritime Organization (IMO) lists the ten most unwanted species as: the Cladoceran Water Flea, the Mitten Crab, Toxic algae (red/brown/green tides), Cholera, the Round Goby, the North American Comb Jelly, the North Pacific Seastar, the Zebra Mussel, the Asian Kelp, and the European Green Crab. The impact of these invasive species can be divided into three main categories: n Ecological threat to the native biodiversity and/or ecological processes n Risk to human health as toxic organisms and pathogens may be introduced, potentially causing illnesses to fauna, flora and humans n Economic impact for fisheries, coastal industry, and other commercial activities and resources than can be disrupted. Cholera (Vibrio Cholerae) The Zebra Mussel (Dreissena polymorpha) 2 In 1991, a ship from Asia brought a new, virulent strain of vibrio cholera to the port of Lima, in Peru, probably through contaminated bilge water. The bacteria soon infected shellfish and spread to humans, rapidly reaching epidemic proportions, with a million cases of cholera and up to 10,000 deaths. Native to the Caspian and Black Seas, it is one of the most infamous examples of a biological invasion. Causing large damages to infrastructure, suffocating natural ecosystems, the mussel s financial impact in the US is estimated at between USD 750 million and USD 1 billion between 1989 and 2000. The Comb Jellyfish (Mnemiopsis leidyi) This carnivorous predator eats all forms of zooplankton, including fish eggs and larvae. Accidentally introduced to the Black and Caspian Seas in the early 80s, the comb jelly caused at least USD 240 million annual losses in catches of marketable fish by disrupting the food chain. The Japanese Seastar (Asterias amurensis) The large yellow and purple starfish is another of those attractive creatures that appear harmless but can have disastrous consequences when they invade new habitats. Native to Japan and northern Pacific area, its density in Tasmania reached 1100 per m 2 in 1995, becoming the dominant invertebrate and voracious predator, eating all that it can find. The direct economic impact as well as the potential long term damages to the environment and people has led to the development of international, national, and regional regulations in order to control the transport and discharge of aquatic organisms. In 2004, the IMO adopted the International Convention for the Control and Management of Ships Ballast Water and Sediments (a.k.a. BWM Convention), which will enter into force 12 months after ratification by 30 states representing 35% of the world merchant shipping tonnage. The ratification process has been complex, but finally the Convention is expected to be ratified in 2012, with its entry into force in 2013. It s time to move
The Ballast Water Management Convention The BWM Convention requires ships to develop ballast water management plans, to maintain ballast water record book, and to undertake certain measures (exchange of ballast water under D-1 rule, and treatment under D-2 standard) to control the ballast water discharges. The limits set by the D-2 regulation are presented in this table. IMO D-2 Standard For Discharge Ballast Water Microorganism category Regulation Plankton, size > 50 µm < 10 viable cells / m 3 Plankton, size 10-50 µm < 10 viable cells / ml Toxicogenic Vibrio Cholerae < 10 Colony Forming Unit / 100 ml Escherichia Coli < 250 Colony Forming Unit / 100 ml Intestinal Enterococci < 100 Colony Forming Unit / 100 ml Also according to the Convention, ship-owners should equip their fleet between 2012 and 2016, depending on the year of construction and the ballast capacity of each vessel. Timeline For Vessels Equipment Year of Construction Ballast Water Capacity (m 3 ) 2012 2013 2014 2015 2016 In or after 2009 < 5.000 Newly Built Vessels After 2009 but before 2012 5.000 D1 or Existing Vessels In or after 2012 5.000 Before 2009 1.500-5.000 Before 2009 < 1.500 or > 5.000 D1 or D1 or 3 During IMO Committee MEPC.61, a paper was submitted with estimates of the number of ships to be equipped with ballast water treatment systems between 2012 and 2020; the numbers speak for themselves. 18 000 16 000 14 000 12 000 10 000 8 000 6 000 4 000 2 000 0 # of vessels required to install a BWMS 2012 2013 2014 2015 2016 2017 2018 2019 2020 Around 40 000 ships are expected to be retro-fitted with treatment systems during this period, which represents 45 ships per day from today. And it is no surprise that this will be the major challenge the shipping world (shipyards, equipment manufacturers, shipowners) will face in the implementation of the BWM Convention. Newly constructed vessels (less than 5 000 m 3 ) Newly constructed vessels (greater than 5 000 m 3 ) Existing vessels (between 1 500 and 5 000 m 3 ) Existing vessels (less than 1 500 or greater than 5 000 m 3 ) Vessels constructed from 2009 to 2011 (greater than 5 000 m 3 ) forward together

Simple, Competitive,
How it works by-pass by-pass S E A FILTRATION UV TREATMENT BALLAST TANK BALLASTING: Filtration + UV disinfection When the pressure gauge indicates clogging of the filter, the self-cleaning cycle is automatically launched. The dedicated backwash pump ensures the discharge of the filtrate, without loss of flow rate while filling the ballast tanks. by-pass by-pass S E A UV TREATMENT DEBALLASTING: UV disinfection only - filtration is automatically by-passed. FILTRATION BALLAST TANK 5 CLEANING: At the end of operation (either ballasting or deballasting) a total purge of the system is performed, followed by flushing and filling of the filter and UV reactors with fresh water. Well proven technology, chemical free Modular: flexible, scalable to any flow rate Easy to install, operate, and maintain ADVANTAGES Automatic operation, easy-to-use interface Safe: no explosive gases, no induced corrosion, no active substances Automatic regulation of power consumption depending on water quality Competitive, quick return on investment Flexible, Compact

SUCCESSFUL TESTING Environmental testing (temperature, humidity, vibration, inclination, power variation, and failure, EMC) was performed in accredited laboratories during summer 2011, in accordance with IMO and class societies requirements. 6 Land-based tests have been performed with both types of filters at DHI facility in Denmark, during fall 2011. All tests passed with flying colors in brackish water (17 PSU; 34 NTU) and marine water (36 PSU; 6 NTU). Shipboard testing is being carried out on 2 container ships in 2012, at 500 and 1000 m 3 /h: n CMA CGM, one of the world leaders in shipping, confirmed its choice of green shipping, and offered to equip one of its vessels to test the BIO-SEA equipment in different Asian harbors n Searching to learn from synergy, MARFRET company anticipated the performance and reliability of the BIO-SEA system and chose to equip one vessel for tests, to be performed in Europe and North America.
