1 Your future BWT system Votre futur système de traitement des eaux de ballast

2 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 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 It s time to move

3 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 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 ) In or after 2009 < Newly Built Vessels After 2009 but before D1 or Existing Vessels In or after Before Before 2009 < or > 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 # of vessels required to install a BWMS Around 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 m 3 ) Newly constructed vessels (greater than m 3 ) Existing vessels (between and m 3 ) Existing vessels (less than or greater than m 3 ) Vessels constructed from 2009 to 2011 (greater than m 3 ) forward together

4 The BIO-SEA Solution 1 ST STEP: FILTRATION ECONOMICAL OPTION ULTRA COMPACT OPTION n 40µm filtering element in stainless steel or duplex, in order to retain suspended solids and zooplankton (microorganism size > 50 µm) n Size to scale depending on the flow rate to treat n Automatic backwash, monitored by a pressure switch n No disruption of the filtration process during the cleaning cycle, and no significant variation of the treated flow rate n Additional suction pump to allow a complete cleaning even if the vessel service pressure is low n Vertical or horizontal configurations available n 2 models of filter are available, one very economic, and one very compact. Housing material and overall shape and position (dimensions, footprint) differ, but test results prove technical performances are identical. 2 ND STEP: UV DISINFECTION 4 n Reactor equipped with a single polychromatic, medium pressure, high intensity UV lamp n A high-quality quartz sleeve protecting the UV lamp n Optimized design by CFD (Computational Fluid Dynamic), taking into account the seawater quality (UV transmittance) and fluid speeds on the quartz sleeves, in order to facilitate cleaning and maintenance n Lamp driven by electronic ballast, allowing precise management of the UV lamp in order to optimize its regulation, reduce the power consumption and prolong its life n Monitoring through UV sensor (intensity) n Modular design, facilitating the installation of UV reactors in parallel and a better adjustment to the flow that has to be treated. MONITORING AND CONTROL n Automated operation and monitoring through sensors and PLC: UV sensor (w/m²), temperature sensor ( C), flow meter (m 3 /h), differential pressure switch (bars), end stroke switch (automatic valves) n Automatic and/or manual operation for ballasting, deballasting, and cleaning n Touch screen interface for easy use and understanding n Recording of operations, alarms, and measured UV intensity (10,000 records of each) covering 24 months n Operator and Administrator Modes n Bus communication for remote control and integration to vessel data system and command control. Simple, Competitive,

5 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
