Ballast and PSC

The article below is taken from the report and shows a selection of system makers’ views on how they see compliance with PSC requirements. The testing systems referred to were covered in greater depth in the Summer 2016 edition of the ShipInsight Journal*. These devices can test samples from the ballast for compliance with the D2 discharge standard and some believe that they – or something like them – should be made a part of all systems. Our question to system makers said, ‘The question of compliance with PSC requirements is an argument that shipowners have put as being a major area of concern. What guarantees can you give as to effectiveness and do you plan to incorporate one or other of the embryonic testing systems into your treatment system’? Here are a selection of the answers:


We are continually working with the rapid compliance tool community to actively monitor our discharge to help Owners know whether or not their systems are working. We have announced a partnership with Bactest to offer their test equipment with our systems for random sampling, and our service technicians have offered to conduct discharge testing for the past two years. We will continue to announce more partnerships and relationships as we test more equipment and are confident that it will give our customers a compliance test that is verified by our own testing through independent laboratories. It is our goal to offer full-time discharge monitoring of our systems as soon as this is practically, and reliably available.


The Alfa Laval PureBallast 3 system is rigorously tested to meet both IMO and USCG requirements on all three salinities, fresh, marine and brackish water. We can with confidence say that we offer a solution which meet the rigorous demands from the regulatory bodies. We are closely following the development of various monitoring system solutions and we believe that such solutions in the future will be incorporated as part of BWM systems.


Compliance at port relies on the proper installation, maintenance, and operation of an approved BWMS that has been assessed to meet the regulations D-2 performance. We are committed in working closely with our customers to ensure proper BWMS operation and compliance throughout the life of the ship. The necessary control and monitoring needed for our system to operate appropriately for conditions typical for maritime trade have been integrated into the Trojan Marinex BWT system and any additional measures to evaluate performance is at the discretion of the operator.


Currently Evoqua doesn’t have any plans to incorporate any testing system like the speedy ballast, at least not before there is one system that is approved by all the administrations that has been extensively tested in operational conditions. The system’s robustness and effectiveness is imbedded in the testing regime, in the quality assurance of the test laboratories used and the administration that has approved all of this prior to granting the BWT system the IMO type approval certificate. The SeaCURE® system’s effectiveness has been extensively tested in different water qualities, water types and marine biological regions, all according to the test requirements set by IMO G8. The effectiveness of the SeaCURE systems has also been tested in fresh water. Fresh water is in fact often considered to be the most difficult water quality to pass because of the biota, etc. Each test has been witnessed, and the results verified and audited by third party approved laboratories – and in every single test the system’s effectiveness has been measured against the IMO D2 discharge standard. The SeaCURE system has passed every repeated test and the test results are available in the public domain. Without the successful tests, BSH in Germany would not have granted the SeaCURE system the IMO Type Approval certificate. If the SeaCURE system is operated under the same or similar conditions to what the system has been tested for, there is no reason to expect the system’s effectiveness to be different. This requires that the ship and the BWT system is operated in accordance with the instructions in the operator’s manual and that the crew have been familiarised and trained in the treatment operations.
* A note on the Summer Journal; Chelsea Technologies and US Coast Guard

The report included a comment attributed to Chelsea Technologies concerning trials of their FastBallast testing system with the US Coast Guard. Chelsea Technologies have asked us to issue the following statement on their behalf ‘In response to the article appearing in ShipInsight Summer Journal, that was attributed to CTG, we wish to make it clear that the USCG has carried out independent evaluation of several manufacturers’ ballast water compliance monitors and that it has expressed no view as to the individual or relative performance of the different equipment. Any statement suggesting the contrary is inaccurate and incorrect.’
