How is a ballast water management system approved?
IMO has provided the testing procedure in its “Guidelines for Approval of Ballast Water Management Systems” (G8 Guidelines). The approval involves shore based testing of a production model to verify whether the D2 standards are complied with, followed by a shipboard testing to check if the system works as desired in service.
How is ballast water pumped through the tank?
Dilution Method: A method by which replacement ballast water is filled through the top of the ballast tank with simultaneous discharge from the bottom at the same flow rate and maintaining a constantlevel in the tank throughout the ballast exchange operation.

What does D1 mean in ballast water exchange?
D1 – Exchange: Ballast water exchange is based on the principle that organisms and pathogens contained in ballast water taken on board from coastal waters will not survive when discharged into deep oceans or open seas, as these waters have different temperatures, salinity and chemical composition.
Where are the ballast bags on a NXT boat?
Completely drain and store the bags in a dry place. With the rear ballast bags removed and the bridge connector in place, identify the three ballast thru-hull vents on the hull sides of NXT boats.
