BALLAST WATER DISPOSAL<br />
• Flow-Through Exchange Method<br />
– 300% of a tank’s full capacity of clean water from the deep ocean<br />
must be pumped into each tank to achieve an acceptable 95%<br />
volumetric exchange.<br />
• Sequential q Exchange g ( (empty p y / refill) )<br />
– Involves emptying tanks of high-risk ballast water at sea be<strong>for</strong>e<br />
refilling them with clean water from the deep ocean.<br />
• Dilution Method<br />
– Tank is partially filled and filling deep ocean water will dilute to<br />
original ballast water to 5%<br />
• Exchange to take place no less than 200 nautical miles from<br />
coast & at water depth of at least 200 m<br />
