Ballast Water Measurements
Discharge of ballast water is controlled by regulation. With Ballast Water Treatment (BWT) being the latest major regulation requirement, great efforts are made to prevent spread of contamination and transfer of aquatic species. The IMO Ballast Water Management Convention (BWM) states, that all vessels above a certain size and below a certain age, must implement, operate and ensure compliance with BWT in both a human health and performance aspect, according to the D2 and D3 standards. BWM implements the possibility to self-monitor by implementing measurement and testing equipment on board and recording periodic results of tests.
