Information about the sampling analysis of ballast water at commissioning tests for BWMS has already been issued as ClassNK Technical Information No.TEC-1199 (dated on 21 February 2020).

At the 77th session of the IMO Marine Environment Protection Committee (MEPC77) held from 22 to 26 November 2021, a Unified Interpretation was approved to interpret that the sampling analysis of individual BWMS should be conducted when BWM surveys (including verification of BWMS installation) are completed on or after 1 June 2022. In the case of new ships, it should be noted this requirement applies to ships for which the date of delivery is on or after 1 June 2022. Furthermore, it should be noted that even when the ship has a Statement of Fact on installation of BWMS, this requirement applies to those ships for which the date of completion of a BWM survey under Regulation D-2 is on or after 1 June 2022.

It is expected that related instructions of flag administrations will be issued in the future and these will be updated on our "Ballast Water Management Convention" website (HOME > Products & Services > Statutory Services > Ballast Water Management Convention).
