Hyde Marine’s Guardian ballast water treatment system has completed all the required testing under 46CFR162.060 and the new IMO Revised G8 requirements, moving it closer to USCG and IMO type-approval
Hyde Marine, a subsidiary of Calgon Carbon Corporation, has announced it has completed shipboard testing of its Guardian-US BWTS in accordance with the DNV GL-created quality assurance project plan.
Calgon Carbon’s president and chief executive Steve Schott said “This is an important achievement as it was our last phase of testing required to apply for USCG type-approval. It was critical to meet our customers’ needs by testing in varied and challenging conditions.”
The final tests were conducted in challenging ’sweet’ fresh water with less than 1 practical salt unit (psu – a measure of salinity). This completes the shipboard testing in all three required levels of salinity. The testing was performed under the direction and supervision of DNV GL, which served as the independent laboratory as required under US type-approval testing. Completing the tests in all three salinity ranges, at multiple temperatures and spanning seasons provided the evidence required of both the function and robust design of the chemical-free Hyde Guardian-US (universal service) BWTS.
Hyde Marine reports it is one of the world’s most successful ballast water treatment technology companies having sold more than 500 of its ballast water treatment systems to date. The Hyde Guardian-US BWTS uses a filtration and ultraviolet disinfection system to treat ships’ ballast water, to prevent the spread of invasive species from port to port.
“Hyde Marine is very pleased to have completed our testing requirements,” said Calgon Carbon UV Technologies/Hyde Marine executive director Chris Todd. “Using one of our first customers as an upgrade platform to prove we could retrofit one of our earliest systems to our newest product was a milestone in which Hyde Marine takes great pride. Our platform proved a strenuous test of our system’s functionality as we work to define the limits of machine operation and disinfection efficacy. We are very satisfied with DHI’s analytical approach as well as their enthusiasm to challenge our system in the shipboard testing environment.”
The Hyde GUARDIAN-US BWTS was tested with water containing organism counts far exceeding IMO and US Coast Guard testing requirements and was tested with water with UV transmittance down to 40% UVT. “We are confident that our system can perform to the expectations of our clients anywhere their vessels may go,” said Mr Todd.
Hyde Marine will now complete the application process and expects to submit their application to the US Coast Guard by the end of 2019.
