CTI-Maritec has received approval from DNV GL as a test facility capable of undertaking ballast water system commissioning tests in line with new rules set to enter into force in October 2021.

The Approval of Service Supplier (AoSS) certification, the first of three classification society approvals expected this year, allows CTI-Maritec to perform biological efficacy testing on DNV GL-classed vessels during the system commissioning stage.

“New regulations will come into force next year requiring ballast water tests to verify installed systems are compliant with the D2 standard during the commissioning process,” explained Michael Haraldsson, global business development manager – ballast water testing, CTI-Maritec. “As an independent testing lab, we are now approved to test all organism size classes specified in the standard along with bacteria, including vibrio cholerae, escherichia coli, and enterococci.”

DNV GL reviewed CTI-Maritec’s standard operating procedures, including sampling methodology and analysis and relevant quality control procedures. The procedures for indicative and detailed analysis were also assessed to ensure they meet the requirements set out in BWM.2/Circ.42/Rev.1) and the D2 standard.

While onboard indicative tests are a minimum requirement, if any discharge sample exceeds the regulatory levels, samples must be analysed by accredited laboratories within a matter of hours of the sample being taken.
