Hyde Marine Records 400th Hyde GUARDIAN Ballast Water Treatment System Order, Continues Proficiency, Strength in Compact Footprint Installations Ahead of Legislation

PITTSBURGH, PA  –  12/18/2014

Hyde Marine, Inc., announced it recorded its 400th order for its Hyde GUARDIAN^® Ballast Water Treatment System (BWTS), which will be installed on a tug boat for an articulated tug barge (ATB) being built by VT Halter Marine at the company’s Pascagoula, MS, facility.

The Hyde GUARDIAN Gold™ (HG60GS) unit was sold by W&O Supply, Inc., Hyde Marine’s exclusive sales distributor in the U.S. and Canada.

According to John Platz, President of Hyde Marine, the announcement comes on the heels of the ballast water treatment company achieving its 300th order in early 2014.

“The rapid pace at which we are adding orders, particularly since spring 2014 is an indication more shipowners and operators are seeking to responsibly address ballast water treatment compliance,” he said. “And, we are pleased to collaborate with W&O and leverage their experience in helping end-users better understand the technical advantages of the Hyde GUARDIAN Ballast Water Treatment System and, in particular, the benefits it provides.”

Hyde Marine ballast water treatment systems are ideal for vessel applications that have short runs, operate in multiple salinities, or require quick turnarounds. Hyde GUARDIAN systems provide a safe, efficient solution to meet ballasting needs without interfering with vessel operations or requiring extra crew time.

Particularly, the Hyde GUARDIAN Gold BWTS is ideal for retrofits as it provides the compact size required by a growing number of ship owners and operators. Hyde GUARDIAN Gold delivers the unique construction and technological specifications necessary to meet stringent ballast water treatment regulations.

Hyde Marine, a wholly owned subsidiary of Calgon Carbon Corporation (NYSE: CCC), is considered to be one of the most experienced BWTS organizations in the world, having delivered more than 340 Hyde GUARDIAN units, and commissioned more than 180 of them for operation on a variety of vessels around the globe – more than any other BWTS company.
