INTRODUCTION The introduction of invasive marine species into a new environment by ballast water attached to ship hulls has been identified as one of the four greatest threats to the world’s oceans. Ballast water is water carried by ships to ensure stability, trim, and structural integrity. Shipping transports over 80% of the world’s commodities, and each year transfers approximately 3 to 5 billion tons of ballast water internationally, which is, absolutely essential to the safe and efficient operation of modern shipping, providing balance and stability to unladen ships. However, it may also pose a serious ecological threat to the marine environment. The transferred species including bacteria, microbes, small invertebrates, eggs, cysts and larvae of various species may survive to establish a reproductive population in the host environment, becoming invasive, out-competing native species, and multiplying into pest proportions. Ballast water treatment is a technology for the treatment of ship ballast water from aquatic invasive species. Port waste reception facility should be modified to include ship ballast water treatment during this transitional phase until 2017. It provides onshore facilities in ports or terminals to transfer ballast water for cleaning or storage. This paper describes ballast water management, in general, and gives perspectives for the Turkish ports, and briefly suggests that the waste reception facilities must be modified for ballast water treatment. KEYWORDS: Port waste reception facility, ballast water, aquatic invasive species, ship-generated waste Ballast is any material used to add weight to balance an object, such as vessel. It is the additional weight necessary to bring the vessel to a suitable draft and trim, reduce stresses, and improve stability 1 . Ships are specifically designed and built to move safely through the water while carrying cargo. When a ship is travelling either without cargo, or only partially laden, it must take additional weight on board to enable it to operate effectively and safely by keeping the ship deep enough in the water to ensure efficient propeller and rudder operation. In the past, many solid materials were used for ballast, including sand, soil, and stones. In the mid 19th century, water was used as ballast, and since the 1950’s, it has completely replaced solid ballast in ships used to carry heavy loads. Ballast water systems are now an integral part of ship design, and they contribute to stability and balance as well as structural integrity of the hull. Ballast water is pumped into specially designed tanks distributed throughout the hull as ships are offloaded, and pumped out again on arrival to a port where cargo is to be loaded (Fig. 1) 1, 2 . It is estimated that 10 billion tons of ballast water is transferred globally each year, and that 7,000 invasive species are carried around in ballast water every day 2 . There are thousands of marine species that may be carried in ship ballast water; basically anything that is small enough to pass through a ship’s ballast water intake ports and pumps. These include bacteria and other microbes, small invertebrates, and the eggs, and cysts and larvae of various species. The problem is compounded by the fact that all marine species virtually have life cycles that include a planktonic stage or stages. 2. AQUATIC INVASIVE SPECIES * Corresponding author Marine plants, animals, and microbes are carried around the world attached to the hulls of ships and in ship 2895 © by PSP Volume 23 – No 11a. 2014 Fresenius Environmental Bulletin FIGURE 1 - Ballast Water Cycle between ports ballast water. When discharged into new environments, they may become invaders and seriously disrupt the native ecology and economy. They displace native aquatic life, alter habitat, ecosystem and food web, and cause severe fouling problems on infrastructure and vessels. Introduced pathogens may cause diseases and death in humans. International Maritime Organization (IMO) Globallast has identified ten of the dangerous species. These are cholera (Vibrio cholerae, some cholera epidemics appear to be directly associated with ballast water), cladoceran water flea (Cercopagis pengoi), mitten crab (Eiocheir sinensis), toxic algae (red, brown, and green tides, may form harmful algal blooms depending on the species), round goby (Neogobius melanostomus), North American comb jelly (Mnemiopsis leidyi), North Pacific seastar (Asterias amurensis), zebra mussel (Dreissena polymorpha, fouls all available hard surfaces in mass numbers), Asian kelp (Undaria pinnatifida), and European green crab (Carcinus maenas) 1 . The Straits of Istanbul and Çanakkale are among the busiest seaways around the globe. Approx. 50.000 ships passed these straits and 22.300 ships visited Turkish ports during 2011. The majority of the ballast water (BW) volume discharged to Centroid Moment Tensor (CMT) area was from the Mediterranean Sea (69%), which was followed by North East Atlantic (11%), North West Atlantic (10%), and Indo-Pacific Ocean (6%). The highest BW discharge volume belongs to the Western Mediterranean Sea with ~14.061.894 tones 3 . 3. INTERNATIONAL APPROACHES FOR THE BALLAST WATER MANAGEMENT The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM) is a new international convention to prevent the potentially devastating effects of the spread of harmful aquatic organisms carried by ship ballast water, and it has been adopted by the IMO, the United Nations agency responsible for the safety and security of shipping and the prevention of marine pollution from ships. The instrument was adopted at an international conference held from February 9-13, 2004 at IMO's London headquarter. The Convention will require all ships to implement a Ballast Water and Sediments Management Plan. All ships will have to carry a Ballast Water Record Book and will be required to carry out ballast water management procedures to a given standard, following a phase-in period. A number of guidelines has been developed to facilitate the implementation of the Convention. The Convention is divided into Articles; and an Annex, which includes technical standards and requirements in the Regulations for the control and management of ships' ballast water and sediments 4 . The Convention will enter into force 12 months after ratification by 30 countries, representing 35 % of world merchant shipping tonnage. As of 30 September 2013, there were 38 contracting states, and 30.38% of world merchant shipping tonnage ratified the convention 4 . Several strategies have been developed for reducing the risk of spreading Invasive Alien Species (IAS) through ballast water, such as: 2896 © by PSP Volume 23 – No 11a. 2014 Fresenius Environmental Bulletin a) Minimizing uptake of organisms into ballast water tanks. Avoiding ballast water uptake in shallow and turbid areas, e.g., where propellers can stir up sediment, and avoiding uptake at night when many organisms migrate vertically to feed, thereby reducing the number of organisms that enter ballast water tanks; which have ships generating oily bilge water and other residues that cannot be discharged into the sea, which are loading crude oil, loading and discharging bulk cargo in respect to oil residue from combination carriers, in which 1000 tons/day oil other than crude oil is loaded, having ship repair yards and providing tank-cleaning facility 6 . b) Removing ballast sediment. Routine cleaning of ballast water tanks and removal of sediment in mid-ocean or at specific facilities provided in ports reducing the number of organisms that are transported; c) Avoiding unnecessary discharge of ballast water. Where cargo handling demands uptake and discharge of ballast water within a port, water taken up in another area should not be discharged, if avoidable; d) Ballast water exchange. Ballast water can be exchanged between ports, mid-ocean, and in deep water, in order to reduce the risk of organisms carried in the water finding a suitable environment on discharge; e) Treatment of ballast water. Several methodologies that seek to remove or render harmless organisms in ballast water while in tanks and on ships are in development or being piloted. This includes mechanical treatment (e.g., filter or cyclonic separation), physical treatment (e.g., ultraviolet, ultrasound, or heat treatment), chemical treatment (e.g., the use of disinfectants or biocides), biological treatment, or a combination of these; f) Discharge to reception facilities. Discharge of ballast water to reception facilities prevents organisms transported in ballast water from releasing into the wild 2 . 3.1 Reception Facilities The establishment of adequate waste reception facilities (WRFs) is a necessary step to reduce and eliminate ship-generated pollution 5 . WRFs should be designed by taking into account the ship types that may be anticipated to use them. Consideration should be given to the requirements for ballast tank cleaning that may take place and of repair facilities in the area(s) the reception facility serves. The capabilities and any capacity limitations of reception process (facilities and equipment’s) should be made available to ships wishing to use the facility. The details made available to ships should include but not be limited to: 1) maximum capacity (volume or weight) of sediment, 2) maximum volume or weight that can be handled at anyone time, 3) packaging and labeling requirements, 4) hours of operation, 5) ports, berths, areas where access to the facility is available, 6) ship-to-shore transfer details, 7) if ship or shore crew are required for the transfer, 8) contact details for the facility, 9) how to request use of the facility including any notice period and what information is required from the ship, 10) all applicable fees, and 11) other relevant information 6 . A port WRF needs to be introduced to seaport and terminals entertaining ships with sludge tank, in addition to all ports 3.2 Ballast Water Reception Facility A ballast water reception facility (BWRF) should be capable of receiving ballast water from ships so as not to create a risk to the environment, human health, property and resources arising from the release to the environment of harmful aquatic organisms and pathogens. A facility should provide pipelines, manifolds, reducers, equipment and other resources to enable, as far as practicable, all ships wishing to discharge ballast water in a port to use the facility 6 . 3.3 Sediment Reception Facility The BWM, under Article 5, sediment reception facilities (SRFs) undertake to ensure that ports and terminals where the reception facilities have adequate units for cleaning or repairing of ballast tanks to receive the sediments 6 . 3.4 Reception Facilities at the Turkish Ports Turkey has 295 port facilities including tanker terminal, bulk terminal, fishing and yacht port. The Turkish National Railway System (TCDD) is managing 7 ports of them, 17 ports are being managed by the Turkish Maritime Lines (TDI), 2 tanker terminals are managed by the Turkish Petroleum Refineries Corporation (TUPRAS), and 20 ports are being managed by other local administrations. And also 50 small ports are being managed by local municipalities, 53 ports are being managed by the private sectors, 13 yacht harbors are being managed by the Ministry of Tourism, and 128 fishing harbours are being managed by the local co-operatives and municipalities 7, 8 . In Turkey, a total of 177 ports have port WRFs. Mobile waste reception ships and vessels are working for small ports. WRFs in Turkey are facilities where shipgenerated wastes of Annex I (oil), Annex IV (sewage), and Annex V (garbage) of MARPOL (73/78) are stored, treated, and disposed in. Capacity of these facilities and treatment methods may vary because of regionaleconomic reasons. WRFs started to be established a few years ago 5 . At present, they do not receive and treat ballast water and sediment from ships. These additional treatment systems are expected to demand one more year. Even though all port WRFs must be ready to receive ballast water and sediment from ships in 2017, when all ships must have installed ballast water treatment systems (BWTSs) at 2017. 2897 © by PSP Volume 23 – No 11a. 2014 Fresenius Environmental Bulletin 4. OUTLOOK IMO adapted the BWM at 2004 but it is not in force yet. All new and existing ships will install BWTSs until 2017. Some shipping companies installed the BWTSs to their ships. 60 BWTSs were in the maritime sector at 2010 but new ones are expected to come every year. BWTSs can effectively accomplish sterilization for the ballast water flowing into the ballast tank of ships and, thereby, prevent all kinds of pollution to seawater related with ballast water discharge by removing aquatic invasive species from ballast water. BWTS, a system for treatment of ballast water used in ships, is very expensive; therefore, ballast and sediment reception facilities are alternative solutions for ships` owners. If most of the Turkish ports will be effective to use ballast water reception at their WRFs, it will be the main and most practical solution for ballast water treatment until 2017.
