– Regulation D-1 addresses the Ballast Water Exchange standard and The Convention includes two regulations that define ballast water management standards In order to show compliance with the requirements of the Convention, each ship shall have on board a valid Certificate, a Ballast Water Management Plan and a Ballast Water Record Book. The BWM Convention entered into force on 8th September 2017. The Ballast Water Management (BWM) Convention is applicable to new and existing ships that are designed to carry ballast water and are of 400 gross tonnages and above. This Convention is intended at stopping the introduction of superfluous aquatic organisms and pathogens through the discharge of ballast water and sediments. The global community, under the administration of IMO has adopted the “ International Convention for the Control and Management of Ship’s Ballast Water and Sediments, 2004”. Steps T o Reduce Hazards Associated with Ballast Water The introduction of these harmful marine organisms and other similar pathogens has caused major damage to many of the worlds’ coastal regions and bio-diversities over the years.Įxamples of such organisms are Golden Mussels, Zebra Mussels, North American Comb Jellyfish, the Cladoceran Water Flea, and the North Pacific Seastar. While ballast water remains indispensable for safe, secure and effectual shipping operations, it has been scientifically researched and proven by expert authorities that ballast water is a significant path for the transfer of harmful and equally damaging aquatic organisms and other pathogens that pose serious ecological, economic and health problems and if introduced into the sea including estuaries, or into fresh water courses, may create hazards to the environment, human health, property or resources, impair biological diversity or interfere with other legitimate uses of such areas. A good ballast water management plan is imperative for all types of ships.īallast water reduces stresses on the vessel’s hull, balances off for the weight loss due to consumption of water and fuel, provides better manoeuvrability with sufficient vessel draft, including ship propeller immersion, and also helps in improving living conditions of the crew aboard by reducing vibrations and uncontrolled vessel’s movements. Whether or not the ship is at sea, ballast water is carried on all seagoing vessels big or small to maintain acceptable stability conditions. Ballast water has been an integral component of the ship’s stability since the steel-hulled vessels have been introduced.
