According to US EPA’s Final 2013 VGP (188.8.131.52.1.1.3 Ballast Water monitoring equipment calibration):
“At a minimum, all applicable sensors and other equipment must be calibrated annually. Additionally, all applicable sensors and other control equipment must be calibrated no less frequently than recommended by the sensor or other equipment manufacturer, or by the ballast water treatment system manufacturer or when warranted based on device drift from a standard or calibrated setting. EPA expects many sensor types (e.g., pH probes, TRO sensors, turbidity sensors) will need to be calibrated on a more frequent basis. Calibration of the sensors and equipment can be conducted on-board the vessel or they can be removed and shipped to the manufacturer or other vendor for calibration. During the period when the sensors are not installed (or otherwise inoperable thus significantly compromising the performance of the ballast water treatment system), the vessel must not discharge ballast water.
ATS service engineers are well trained for field sensor calibration using certified Fluke calibration equipment. We validate calibration of the following measuring equipment:
ATS will issue a BWTS Health-Check Report at the end of attendance.
Annual maintenance & VGP:
To save Ship Owners money on travel and accommodation, ATS can also assist with collecting VGP samples and arranging their testing in one of the environmental testing laboratories ATS partners with.
