BALLAST WATER MANAGEMENT

MARINESHELF publishes articles contributed by seafarers and other marine related sites solely for the benefit of seafarers .All copyright materials are owned by its respective authors or publishers.
International Convention for the Control and Management of Ships' Ballast Water and Sediments 2004
Adoption: 13 February 2004
Entry into force: 12 months after ratification by 30 States, representing 35 per cent of world merchant shipping tonnage.
BALLAST WATER MANAGEMENT
to prevent, minimize and ultimately eliminate the transfer of harmful aquatic organisms and pathogens through the control and management of ships' ballast water and sediments.
Parties should ensure that ballast water management practices do not cause greater harm than they prevent to their environment, human health, property or resources, or those of other States.
BALLAST WATER MANAGEMENT
Ships are required to be surveyed and certified and may be inspected by port State control officers ,who can verify that the ship has a valid certificate; inspect the Ballast Water Record Book; and/or sample the ballast water. If there are concerns, then a detailed inspection may be carried out and "the Party carrying out the inspection shall take such steps as will ensure that the ship shall not discharge Ballast Water until it can do so without presenting a threat of harm to the environment, human health, property or resources."
Annex - Section A General Provisions
The discharge of Ballast Water shall only be conducted through Ballast Water Management, in accordance with the provisions of this Annex.
Annex - Section B Management and Control Requirements for Ships

Required to have on board and implement 

a Ballast Water Management Plan 
approved by the Administration 

(Regulation B-1).
Ships must have a Ballast Water Record Book (Regulation B-2) to record when ballast water is taken on board; circulated or treated for Ballast Water Management purposes; and discharged into the sea. It should also record when Ballast Water is discharged to a reception facility and accidental or other exceptional discharges of Ballast Water
Implementation Schedule
·Ships constructed before 2009:-
    Ballast water capacity of between 1500 and 5000 cubic metres must conduct ballast water management that at least meets the ballast water exchange standards or the ballast water performance standards until 2014, after which time it shall at least meet the ballast water performance standard.
·Ballast water capacity of less than 1500 or greater than 5000 cubic metres must conduct ballast water management that at least meets the ballast water exchange standards or the ballast water performance standards until 2016, after which time it shall at least meet the ballast water performance standard.
Implementation Schedule-contd…
Ballast water capacity < 5000 cu.m
     - Ships constructed in or after 2009 , must conduct ballast water
        management that at least meets the ballast water
        performance standard.
Ballast water capacity => 5000 cu.m:-
      - Ships constructed in or after 2009 but before 2012, shall
         conduct ballast water management that at least meets the standard
         described in regulation D-1 or D-2 until 2016 and at least the ballast
          water performance standard after 2016.
      - Ships constructed in or after 2012, shall conduct ballast water
         management that at least meets the ballast water performance
          standard.
Ballast Water Exchange
whenever possible,  ballast water exchange to be conducted at least 200 nautical miles from the nearest land and in water at least 200 metres in depth
in cases where the ship is unable to conduct ballast water exchange as above, this should be as far from the nearest land as possible, and in all cases at least 50 nautical miles from the nearest land and in water at least 200 metres in depth.
Ballast Water Exchange
When these requirements cannot be met areas may be designated where ships can conduct ballast water exchange. All ships shall remove and dispose of sediments from spaces designated to carry ballast water in accordance with the provisions of the ships' ballast water management plan (Regulation B-4).
Annex - Section D Standards for Ballast Water Management
Regulation D-1 Ballast Water Exchange Standard - Ships performing Ballast Water exchange shall do so with an efficiency of 95 per cent volumetric exchange of Ballast Water. For ships exchanging ballast water by the pumping-through method, pumping through three times the volume of each ballast water tank shall be considered to meet the standard described. Pumping through less than three times the volume may be accepted provided the ship can demonstrate that at least 95 percent volumetric exchange is met.
Annex - Section D Standards for Ballast Water Management
Regulation D-2 Ballast Water Performance Standard - Ships conducting ballast water management shall discharge less than 10 viable organisms per cubic metre greater than or equal to 50 micrometres in minimum dimension and less than 10 viable organisms per milliliter less than 50 micrometres in minimum dimension and greater than or equal to 10 micrometres in minimum dimension; and discharge of the indicator microbes shall not exceed the specified concentrations.

Ballast Water Management Systems
must be approved by the Administration
These include systems which make use of :--chemicals or biocides;
    -organisms or biological mechanisms;
    -or which alter the chemical or physical
      characteristics of the Ballast Water.
Ballast W
Ballast Water Management systems must be approved by the Administration in accordance with IMO Guidelines (Regulation D-3 Approval requirements for Ballast Water Management systems). These include systems which make use of chemicals or biocides; make use of organisms or biological mechanisms; or which alter the chemical or physical characteristics of the Ballast Water.

Ships need to carry ballast water for stability purposes, and to correct any problem Ballast water management plan in list, trim, etc. Many species of bacteria, plants, and animals can survive
