Potable Water

Water quality standards vary from country to country and meeting the minimum standards from some flag states can prove challenging. Our worldwide network helps customers monitor the water quality on their ships, helps them maintain higher quality levels and reduces the risk of infection or illness.

Greywater

Ships produce greywater/graywater as a normal part of operations. Everyone knows what sewage is, but what about greywater? The International Maritime Organisation or IMO defines it as “the drainage from dishwater, shower, laundry, bath and washbasin drains.” The dangers of untreated sewage are generally well known, however, most people don’t realise that untreated greywater can be just as harmful.

The U.S. Environmental Protection Agency (EPA) reports that untreated greywater is very similar to domestic sewage and can even have higher concentrations of certain components. Some components in untreated vessel greywater can be up to three times higher than untreated domestic wastewater and can contain harmful chemicals, pathogens, bacteria, metals, food waste and problematic nutrients.

Part 2.2.15.2 of the 2013 VGP specifies that new build vessels constructed on or after December 19, 2013, and with a maximum crew capacity greater than or equal to 15, and providing overnight accommodations to those crew are required to collect samples of graywater discharge for analysis.  For these vessels, the 2013 VGP requires two samples a year which are to be collected, at least 14 days apart.

Bilgewater

Part 2.2.2 of 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 bilgewater into U.S. waters, to collect a sample of bilgewater effluent (discharge from the vessel after bilgewater treatment system) annually and to analyse for oil and grease content.

Sewage treatment testing

We advise our clients about the regulations and ensure that their sewage treatment plants are operating under the provisions of Marpol and MEPC resolutions. Sampling and onboard testing can be offered at various ports and we can offer appropriate sampling kits on request.

Exhaust Gas Scrubber Washwater

Part 2.2.26 of the 2013 VGP specifies that twice during the first year of permit coverage or system operation, whichever is later, each vessel operating a wet exhaust gas scrubber system must collect and analyze exhaust gas scrubber-related samples. One of those samples may be conducted as part of a vessel’s annual or other survey, and during the first year of system operation, one of those sampling events may be conducted as part of the system installation to ensure it is functioning properly. The two samples must be collected at least 14 days apart.  After the first year, samples must be collected at least once per calendar year and may be collected as part of the vessel’s annual survey as appropriate.

Overall

With all our tests, Mr. Marine Ballast ensures that your vessels comply with the Vessel General Permit (VGP) or soon to become Vessel Incidental Discharge Act (VIDA). Both VGP and VIDA guidelines outline a structured framework for the regulation of several types of water discharge. The standards to manage discharges are outlined in the Act and followed closely by Mr. Marine Ballast.
