Trojan Marinex BWTS Earns USCG AMS Acceptance

Trojan Marinex ballast water treatment system receives U.S. Coast Guard AMS acceptance for all water qualities

Trojan Technologies’ Trojan Marinex ballast water treatment (BWT) product suite is one of the few to receive United States Coast Guard (USCG) Alternate Management System (AMS) acceptance, in accordance with the USCG’s final rule for Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. waters, for all water qualities: freshwater, brackish water and marine water.

While AMS is an important certification, Trojan said USCG Type Approval continues to be its main objective. “We remain committed to being one of the first BWT system suppliers to achieve U.S. Coast Guard Type Approval, and continue to take the necessary steps to achieve this goal,” said Marv DeVries, president, Trojan Technologies.

AMS is a temporary designation given to a ballast water treatment system approved by a foreign administration. Vessels operating in U.S. waters may use an AMS-designated BWT system to manage their ballast water discharges in lieu of ballast water exchange for a period of five years from a ship’s compliance date while that BWT treatment system undergoes USCG Type Approval testing. AMS certification neither guarantees nor implies that USCG Type Approval is likely, as the two programs are independent of each other.

The Trojan Marinex BWT product suite is tested and IMO Type Approved to the lowest UV transmittance value in the industry (corresponding to poor water quality) under full flow conditions. Testing was conducted under the supervision of DNV, who is certified as an Independent Lab (IL) by the USCG, in accordance with United States Environmental Protection Agency (USEPA) Environmental Technology Verification (ETV) Ballast Water Protocol. The ETV protocol is a key testing requirement for systems to obtain USCG Type Approval.
