Hyde Marine Completes Land-Based Testing for USCG Type Approval

PITTSBURGH, PA  –  11/01/2018

Hyde Marine, a division of Calgon Carbon Corporation, announced today that it successfully completed its land-based testing for the Hyde GUARDIAN® ballast water treatment system (BWTS) that covers both USCG Type Approval requirements and Revised IMO G8 Guidelines.  The testing protocol requires a minimum of 15 successful test runs in three different water salinities under varying and extremely challenging water conditions.

The Hyde GUARDIAN® BWTS utilizes filtration with medium-pressure UV for disinfection.  The system originally received IMO Type Approval in 2009, and USCG Alternate Management System acceptance in 2013.  Completion of this new round of land-based testing in accordance with the USCG preferred stain test method is a key step in the application process for USCG Type Approval, as well as qualifying the system under the Revised IMO G8 Guidelines.  The phases of the USCG Type Approval process include documentation review, bench testing, land-based testing, shipboard testing, and environmental testing.

“Completion of land-based testing is a great milestone for our team and for our product,” says Chris Todd, Executive Director of Hyde Marine.  “We are still in the process of shipboard testing for the Hyde GUARDIAN® system, and we expect to be able to submit our USCG Type Approval application in the summer of 2019 following its completion.  We are eager to help ship owners comply with both USCG and IMO ballast water management regulations.”
