EDISON CHOUEST OFFSHORE SIGNS LETTER OF INTENT WITH HYDE MARINE FOR SUPPLY OF HYDE GUARDIAN BALLAST WATER TREATMENT SYSTEMS

PITTSBURGH, PA  –  09/23/2014

Hyde Marine, Inc., a wholly owned subsidiary of Calgon Carbon Corporation (NYSE: CCC), has been selected as a strategic supply partner for ballast water treatment (BWT) systems by Edison Chouest Offshore (ECO) for use on ECO’s extensive fleet of vessels.

The chemical free Hyde GUARDIAN Gold™ BWT system, which has both International Maritime Organization (IMO) Type Approval and United States Coast Guard (USCG) Alternative Management System (AMS) approval, uses efficient filtration and ultraviolet (UV) disinfection to treat ships’ ballast water to prevent the spread of invasive species from port to port.

Hyde Marine executed a Letter of Intent with ECO to guarantee the availability of BWT systems for compliance with regulations for ECO’s growing fleet of more than 250 vessels.

ECO has ordered more than 15 Hyde GUARDIAN systems to date with several already installed and in operation.  Hyde Marine is also supplying a complete functional system for the crew training center at ECO headquarters in Cut Off, LA, to support regular training of crew and shipyard personnel on BWT system operation and installation requirements.

The Hyde GUARDIAN BWT System offers a compact, modular design with low power consumption, low-pressure drop, and simple, fully automatic operation, making it a technically attractive solution for any type of vessel.

John Platz, President of Hyde Marine, Inc., commented, “ECO is recognized as one of the most diverse and dynamic marine transportation solution providers in the world.  Hyde Marine is pleased to be the BWT technology chosen by ECO to help the company meet its regulatory obligations and growth objectives.”

The Hyde GUARDIAN Ballast Water Treatment System was one of the first to receive IMO Type Approval in April 2009 and AMS approval from the United States Coast Guard in 2013, which positions the company as a leader in providing the maritime market with the equipment and information it needs regarding ballast water treatment compliance.

AMS approval allows the Hyde GUARDIAN BWT System to be used on vessels for five years after the vessel is required to comply with the USCG Ballast Water Discharge Standards.

“Partnering with Hyde Marine has helped us to comply with ballast water treatment regulations,” said James Solar, Purchasing/Special Projects Manager for Edison Chouest Offshore. “As our company continues to expand to provide offshore service to the maritime industry, we can move forward knowing that we are employing one of the industry’s leading ballast water treatment systems.”
