What is D-2 Commissioning Testing of BWTS?

Commissioning Testing validates the installation of the BWTS by demonstrating that its mechanical, physical, chemical and biological processes are working correctly – as per the design specifications or so-called Type Approval. If your ship(s) uses a Ballast Water Treatment System (BWTS) you must comply with international regulations for ballast water management, including conducting a Commissioning Test on your newly installed BWTS.

The applicable regulation states that D-2 Commissioning Tests can only be performed by an independent service provider, other than the BWTS manufacturer, shipyard or installation company. Preparation is fundamental for successful and timely completion of the test, both by the shipowner as well as by the service provider. You can book your D-2 Commissioning Test now to keep your fleet compliant and be able to present all documents to Port State Authorities.

Why you need D2 Commissioning Testing?

The International Maritime Organization (IMO) adopted the Ballast Water Management Convention (BWM Convention). That IMO BWM Convention requires vessels to comply with the D-2 Standard by September 2024. In order to comply with the D-2 standard, installation of a Type-approved BWTS is needed. Prior to using a newly installed BWTS on board of a vessel, it must be Commissioning Tested in line with BWM.2/Circ.70/Rev.1 as of June 1st 2022. A successful Commissioning Test and Report is one of the requirements to obtain the International Ballast Water Management Certificate.
