Local Company's Innovative Approach Approved by US Coastguard.

Linby based Coldharbour Marine have secured US Coast Guard Alternate Management System (AMS) approval for their patented Ballast Water Management System (BWMS). This means that the system can be fitted into commercial vessels servicing United States ports.

USCG regulations require all ships calling at US ports to carry out ballast water treatment to prevent the introduction of invasive species into new environments. The Alternate Management System avoids penalising ships that have already fitted a treatment system which has been approved by another flag administration.

Coldharbour had previously secured UK Marine and Coastguard Agency type approval under the watchful eye of Lloyds Register, who independently audited their land and sea tests.   Andrew Marshal, Chief Executive of Coldharbour Marine, said,

“The MCA is recognized in the US as a tough accrediting body so it took only 4 months since gaining initial accreditation to win full AMS approval.”

Coldharbour’s BWMS is based upon established marine technology and has very low maintenance costs, the system requires minimal crew training to operate and maintain.

Earlier this year, Coldharbour won an award for its innovative approach to resolving the challenges associated with treating the large volumes of water stored in the ballast tanks of large carriers and tankers. Each ballast water system costs between £750,000 and £1.5m and over 90% of Coldharbour’s production will be exported.
