Part A - Ballast Management Practices

Section 1 - Ballast Management Options for Deep Sea Voyages
A.    Ballast water exchange
1. Introduction: Near-coastal (including port and estuarine) organisms released in the [deep sea,] and oceanic organisms released in coastal waters, do not generally survive. Ballast water exchange in the at deep sea, such as through sequentially emptying and refilling the ballasted tanks or causing water to flow-through ballasted tanks, can therefore reduce the probability of transfers of harmful aquatic organisms and pathogens.
2. Safety: When exchanging ballast at sea, guidance on safety aspects of ballast water exchange as set out in part B of the this Appendix shall be [taken into account][followed]. When exchanging ballast water at sea, the ship's safety shall be of paramount importance and the appropriate conditions set out in ..... shall be strictly observed.
3. [Location: Ships shall conduct ballast water exchange in water 500 meters or more in depth and 200 nautical miles or more from shore.]
4. Techniques: When conducting ballast water exchange, one of the following techniques shall be employed:
- The sequential method. Where this method is employed, all of the ballast water should be discharged until suction is lost, and stripping pumps or eductors should be used if possible; and
- The flow-through method. Where this method is employed in the deep sea by pumping ballast water into the tank or hold and allowing the water to overflow, at least three times the tank volume should be pumped through the tank.
Proposed amendments Part A, Section 1.A

Sweden proposes the following:
Section 1 - Ballast Management Options for Deep Sea Voyages Open Ocean Voyages
A. 1. Introduction: Near-coastal (including port and estuarine) organisms released in the [deep sea]open ocean and oceanic organisms released in coastal waters, do not generally survive. Ballast water exchange in the at [deep sea,] open ocean, such as through sequentially emptying and refilling the ballasted tanks or causing water to flow-through ballasted tanks, can therefore reduce the probability of transfers of harmful aquatic organisms and pathogens.
  2. Safety: When exchanging ballast at sea, guidance on safety aspects of ballast water exchange as set out in part B of the this Appendix shall be [take into account][followed]. When exchanging ballast water at sea, the ship's safety shall be of paramount importance and the appropriate conditions set out in .... shall be strictly observed.
  3. [Location: Ships shall conduct ballast water exchange in water 500 meters or more in depth and 200 nautical miles or more from shore.]
  Location: ships shall conduct ballast water exchange in deep water, in open ocean and as far as possible shore,[but not less than 200 nautical miles][ and in water depths of 500 meteres or more].
  4.
- The flow-through method. Where this method is employed in the [deep sea] open ocean by pumping ballast water into the tank or hold and allowing the water to overflow, at least three times the tank volume should be pumped through the tank.
