Plan your IMO D2 Commissioning testing. Contact us here.
Biological testing for IMO D2 standards is only required in the commissioning phase and before the International Ballast Water Management Certificate is issued. As of June 1st 2022, commissioning sampling is compulsory and cannot be organised by the maker. As per regulations, analyses should be conducted on Total heterotrophic bacteria, E. Coli and Enterococci.
As per BWM.2/Circ.70/Rev.1, validation is successful if the water sample does not exceed D2 standards and the self-monitoring equipment indicates correct operation. Most flag states require indicative sampling on board the vessel, therefore laboratory testing is not required unless the water fails the onboard indicative sampling. The current exception to this rule is for Cyprus flag vessels that require laboratory testing as part of the commissioning process.
According to the current rules and regulations, there is no requirement for annual D2 testing. Such testing could be introduced in the future.

Vessels sailing to US waters require USCG-approved BWT systems.
During the first year, water needs to be tested between 2 to 4 times. If sampling results are below permit limits for two consecutive events, then sampling may be reduced to one time per year.
If the vessel exceeds the limits, it should return to monitoring twice a year. Analyses should be conducted on Total heterotrophic bacteria, E. Coli and Enterococci. Compliance with these VGP requirements is administered by the EPA which requires that tests are carried out according to their specific guidelines.
An accredited technician will take the necessary samples and analyse them for organisms, according to the IMO BWM.2/Circ.70/Rev.1 and G2 guidelines.
D2 commissioning testing can be performed upon request in combination with VGP testing. With our worldwide network of testing locations, we can assist you in your next port of call!
