Bilge Water Analysis

Bilge Water

The 2013 VGP requires owners/operators of new build vessels constructed on or after December 19, 2013 and greater than 400 gross tons that may discharge bilge water into U.S. waters, to collect a sample of bilge water effluent (discharge from the vessel after bilge water treatment system) annually for analysis of oil and grease content .

In addition, the 2013 VGP requires that a reading of the OCM be recorded at the time of sample collection so that the oil content measured by the laboratory can be compared to that measured by the OCM.
