Mandatory BWMS Commissioning Test required from 1 June 2022


Commissioning testing in accordance with IMO guidance BWM.2/Circ.70/Rev.1 is now mandatory for Ballast Water Management Systems (BWMSs) installed on newbuilds and existing ships of all flag administrations when the initial BWMS commissioning survey is completed on or after 1 June 2022.

This test is required even if the system has been partially installed and/or commissioned before 1 June 2022.

The commissioning test is also mandatory for the additional commissioning survey required after a change, replacement or significant repair of the BWMS necessary to achieve full compliance with the D-2 standard.

The IMO has also approved a Uniform Interpretation (UI) of regulation E-1 in BWM.2/Circ.66/Rev.2. This UI clarifies that if the initial or additional survey is completed on or after 1 June 2022, the commissioning test is mandatory. If the initial or additional survey is completed before 1 June 2022 the commissioning test of the BWMS remains subject to the specific requirements of the flag administration.
