Dealing with ongoing maintenance, re-retrofit and operational issues and D2 testing requires a qualified partner with a global reach and experience.
Since 2010, Goltens Green Technologies’ has supported almost 1200 ballast water treatment system retrofit projects making us the leader in this space. As an independent retrofit partner, we represent no particular manufacturer or technology but have undertaken projects with systems from Optimarin, Bio-UV, Headway, Severn Trent DeNora, Alfa Laval, Ecochlor, Techcross, Samsung, Panasia Auramarine, NK, Hyde Marine, Wärtsilä, SunRui, Trojan Marinex and many others.
Since 2010, we have installed just about every type of ballast water treatment system across a wide range of vessel types. This extensive hands-on experience enables us to support shipowners with ballast water system retrofits, upgrades, troubleshooting, and
ongoing service.
With shipping authorities placing increasing emphasis on compliance with ballast water management requirements, maintaining a reliable BWT system and accurate ballast water records is essential to avoid operational disruptions and vessel downtime.
Rely on Goltens for ballast water system re-retrofitting, IMO D-2 commissioning, and comprehensive support services. Our annual inspections and surveys help ensure your system remains compliant, operates as intended, and continues to perform efficiently throughout its service life.
IMO-Compliant Commissioning Testing of Ballast Water Management Systems
Effective from 1 June 2022, Regulation E-1 of the Ballast Water Management Convention will enter into force requiring all vessels fitted with a Ballast Water Management System (BWMS) to complete commissioning testing to demonstrate compliance with the IMO D-2 Discharge standard.
To support shipowners globally, Goltens stations offer Class-approved, onboard indicative testing and reporting at major ports around the world completed in compliance with BWM.2/ Circ.70/Rev.1, ‘Guidance for the commissioning testing of ballast water management systems’.
Commissioning testing is required to demonstrate that the particular type-approved BWMS installed onboard the vessel is performing as designed by demonstrating that its mechanical, physical, chemical and biological processes are working properly.
Note that commissioning testing is not performed to validate the system design. The respective BWMS designs should have been validated during the respective type-approval process and will already have been demonstrated to comply with the IMO D-2 discharge standards.
The required testing must be performed independently to the satisfaction of vessel’s Flag State administration. The testing is not within the scope of standard supplier commissioning, however the BWMS supplier can support the process by arranging or facilitating third-party independent testing. With years of BWMS retrofit experience and hundreds of installations completed, shipowners can confidently engage Goltens’ highly experienced engineers to conduct this testing.
The guidance shown below dictates that system testing should be conducted using local ambient water regardless of the challenges this water may present, and regardless of it being within or outside the original system design limitations.
During ballast water uptake, a sample of ambient water can be taken from the port or even directly from the harbor where the vessel is located. Detailed analysis of the sample is not required, but an indicative analysis may be performed if desired.
A sample is taken during Ballast Water discharge from the system’s sampling point, following full treatment of the Ballast Water. The sample should be collected as close to the discharge point as practical and be representative of the tank or tanks being emptied.
Once the sample has been taken, an indicative onboard test needs to be conducted to demonstrate that the IMO D-2 standard is met. This defines the maximum amount of viable organisms allowed to be discharged as well as a measure of specified indicator microbes harmful to human health
If the indicative sampling conducted onboard is inconclusive, Goltens has partnered with trusted, certified laboratories and can arrange a detailed analysis to confirm compliance. Vessel General Permit (VGP) testing as required by the US EPA can also be conducted by our partner labs.
Once completed, the results of the testing, inclusive of the method used and the test results, need to be filed with the Flag State or class as required by the Flag State
