Trojan gets USCG AMS nod

Sep 05 2014


Trojan Technologies’ Marinex Ballast Water Treatment (BWT) system has received US Coast Guard’s (USCG) Alternate Management System’s (AMS) acceptance.

This was accorded for all water qualities - freshwater, brackish water and marine water. 

While AMS is an important certification, it is not USCG Type Approval which is Trojan’s main objective. “We remain committed to being one of the first BWT system suppliers to achieve US 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 BWT system approved by a foreign administration. Vessels operating in US 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 the system undergoes USCG Type Approval testing.

This certification neither guarantees nor implies that USCG Type Approval is likely, as the two programmes are independent of each other, the company explained.  

The Trojan Marinex BWT system is tested and IMO Type Approved to the lowest UV transmittance value in the industry (corresponding to poor water quality) under full flow conditions, the company claimed.

Testing was conducted under the supervision of DNV GL– who is certified as an Independent Lab (IL) by the USCG – in accordance with US Environmental Protection Agency (USEPA) Environmental Technology Verification (ETV) Ballast Water Protocol.

ETV protocol is a key testing requirement for systems to obtain USCG Type Approval, Trojan explained.
