PITTSBURGH, PA  –  09/08/2016

• Approximately 64,000 ships could be required to comply with ballast water regulations, including the Convention, over the next 5 to 7 years
• Total market size is expected to approximate $18 billion to $28 billion for ballast water treatment systems

Calgon Carbon Corporation (NYSE:CCC) and Hyde Marine congratulate the International Maritime Organization (IMO) on ratification of the 2004 International Convention for the Control and Management of Ships’ Ballast Water and Sediments (the Convention). According to the IMO, today’s accession to the Convention by Finland brings the total number of countries signing the convention to 52, representing 35.14% of the world’s tonnage. By surpassing both 30 signatory countries and 35% of the world’s represented tonnage, the Convention will now come into force on September 8, 2017, twelve months from today’s ratification.

“We are excited that after many years of preparation, we can finally start tackling the problem of invasive species,” said Steve Schott, Calgon Carbon’s Executive Vice President, Advanced Materials, Manufacturing, and Equipment Division. “In anticipation of this day, our Hyde Marine team has been assembling a strong network of partners and suppliers to meet customer demand for our Hyde GUARDIAN Gold® ballast water treatment system (BWTS). Hyde Marine has evolved its design to create one of the most compact, robust, easy-to-operate, and environmentally safe treatment systems to serve the global market.”

«We’re proud to be a part of this moment,» said Randy Dearth, Calgon Carbon’s Chairman, President and Chief Executive Officer. «It has been a long road, but in the end it is the environment that benefits most from implementing this needed Convention. By having sold over 450 systems, we are well positioned to service this very exciting market.»

The Hyde GUARDIAN Gold® BWTS has received IMO Type Approval and uses space-efficient filtration and ultraviolet (UV) disinfection to treat ships’ ballast water to prevent the spread of invasive species from port to port. Due to the uniqueness of its system design and ease of use, Hyde Marine has become a leader in the provision of in-service vessel retrofit systems.

Hyde Marine recently completed land-based testing at DHI in Denmark, under the auspices of the DNV-GL Independent Laboratory. This updated IMO testing provides confidence to ship owners throughout the world that the Hyde GUARDIAN Gold® treatment system is capable of operation in the most challenging water conditions. Hyde Marine now intends to repeat the testing commencing in the first quarter of 2017, using currently required U.S. Coast Guard test methods in its pursuit of achieving U.S. Coast Guard Type Approval.
