D2 Commissioning Testing – All you need to know

Mr. Marine VGP Compliance Sampling

Annually, approximately 10 billion tonnes of ballast water are transported worldwide. Ballast water is essential in ensuring the stability of the vessels. Still, it constitutes a potential source of invasive and damaging species if discharged inappropriately. The International Maritime Organisation (IMO) enforces the installation of Ballast Water Management Systems (BWTS) to ensure the discharged water limits comply with the Ballast Water Management Convention (BWM Convention).

D2 Commissioning Testing

According to IMO, the purpose of commissioning testing is to validate the installation of a BWMS by demonstrating that its mechanical, physical, chemical and biological processes are working properly.

The IMO states that all merchant vessels should comply with the ‘D2 Discharge Standard’ no later than September 2024. Vessel owners must set up commissioning testing of their newly installed BWTS to ratify compliance with IMO and the US Coast Guard (USCG) discharge standards.

Why do I need D2 Commissioning Testing?

The BWM Convention adopted by IMO requires vessels to comply with the D2 Standard and install a BWTS. To deploy the system, it must be commissioned and tested according to BWM.2/ Circ.70/Rev.1 (entered into force on the 1st of June 2022). Commissioning Testing is essential to receiving the International Ballast Water Management Certificate (IBWMC).
