As a shipping company, your (water) installations on board must be compliant with various (international) guidelines. We list the most common guidelines and regulations for you below. The guidelines applicable to your situation depend on the territorial waters in which you are sailing or on how your ship(s) is (are) flagged.


Vessels operating in US territorial waters must comply with the requirements of the 2013 Vessel General Permit (VGP). This will be replaced by the Vessel Incidental Discharge Act (VIDA) in the near future. The VIDA specifies that the 2013 VGP is to remain in force and effect as it is currently written until the new VIDA regulations are enforceable. The law specifies that the permit cannot be modified during that time. Although it is expected to be very similar to the current VGP, it is not yet certain what the exact requirements for sampling and analysis intervals will be. The VGP covers the compliance of ballast and scrubber water.

The Marine Environment Protection Committee (MEPC) deals with environmental issues under the authority of the IMO. This includes the control and prevention of ship-source pollution as defined in the MARPOL Convention. This pollution can be caused by a variety of factors including non-compliant ballast water and scrubber water.
