Hyde Marine, a subsidiary of Calgon Carbon Corporation, has announced that it has successfully been awarded Type Approval by the Norwegian Administration through DNV GL under the newly revised Ballast Water Management Code (BWM Code), also known as MEPC.300(72).

Certification under this newly issued regulatory regime ensures that the Hyde Guardian-US is now available for sale and installation on vessels around the world and will remain so even after the phase-out of the initial IMO Type Approval regime on October 28, 2020.  The system is still under review by the US Coast Guard (USCG) for Type Approval under the requirements of 46 CFR 162.060.

“This is a substantial milestone,” said Chris Todd, Executive Director of Hyde Marine. “This means that over 90% of the world’s fleet that does not discharge ballast water in the United States can begin installing the most advanced ballast water treatment system on the market today. There has been growing uncertainty over the availability of systems after the [October 28] deadline and this puts another key name across the finish line and ready to deliver product into 2021 and beyond.”

When the BWM Code was issued first as MEPC 279(70) on 26 October 2016, the IMO took the stand that ballast water treatment systems need to be certified under a newly revised set of testing guidance or risk having their Type Approvals invalidated two years after the revised test protocols were put into place. When the revised testing procedures were issued in April of 2018, the mechanism was put in place that any system not approved under MEPC.300(72) could no longer be installed on vessels after 28 October 2020.

“We have been testing and developing our Hyde Guardian-US system since the middle of 2015,” said Hyde Marine Senior Market Manager Mark Riggio. “We could have rushed a product to market. We chose to bring the right product to market and to certify it so shipowners will not have to change models mid-way through the implementation cycle.”

Hyde Marine has more than 500 of its ballast water treatment systems sold to date. The Hyde Guardian-US BWTS uses filtration and ultraviolet disinfection. The design closely mirrors the existing Hyde Guardian-Gold product, and customers can easily upgrade their existing equipment to meet the new treatment standard.

The Hyde Guardian-US was tested with water containing organism counts far exceeding IMO and USCG requirements and with demanding water conditions to challenge the limits of system performance. Hyde Marine now awaits the results of the USCG’s review so that the product can be offered to vessels flying the US flag and those limited vessels that trade to, and discharge ballast in, US waters.
