Commissioning testing

Requirement for commissioning testing

The purpose of commissioning testing is to verify correct operation of a ballast water management system (BWMS) and to ensure that the ballast water treated by the system complies with Regulation D-2 at discharge. The verification of each BWMS installation through commissioning testing will become mandatory on 3 October 2021 by the entry into force of Regulation E-1 of the IMO Ballast Water Management Convention. Flag administrations have been encouraged to start commissioning testing as soon as possible, and several administrations such as Singapore, Cyprus, Australia, Bahamas and Panama have already implemented commissioning testing.

Practical approach without sacrificing quality

We have over 10 years of experience with testing of various BWMS in accordance with IMO and U.S. Coast Guard requirements. We are proficient in the scientific methodology used in evaluating the biological performance of BWMS and are approved by DNV GL, Lloyd’s Register and American Bureau of Shipping (ABS) for commissioning testing of BWMS according to IMO BWM.2/Circ.70. 

We have worked closely together with ship owners, ship managers, BWMS manufacturers and class societies and understand the challenges faced by the different parties. Our solution for commissioning testing is an efficient testing procedure that provides assurance that the system has been operated correctly and meets D-2 standards while ensuring that normal ship operations are not affected.

Our team

We have dedicated teams in Singapore and Denmark with extensive experience performing testing of BWMS onboard ships. Our technicians are professional and can be ready for mobilization within a week or shorter notice if necessary.

We understand the fast-paced nature of the shipping industry and strive to be flexible to deliver quick solutions to respond to specific needs.

How does it work?

Customers with a need for commissioning testing of a BWMS are welcome to contact us. We process requests as soon as we receive them, we have smooth procedures for entering agreement, and we work together with the customer to organise the logistics and schedule of the commissioning test. Preliminary results will be available upon discharge on the test day, and a final report will be sent out within 10 working days to the customer.
