Optimarin Buys BWTS Competitor Hyde Marine

Singapore freight forwarders – Star Concord


UV ballast water treatment system builder Optimarin has acquired a competing brand, Pittsburgh-based Hyde Marine, from the Italian conglomerate De Nora. For undisclosed terms, Optimarin is purchasing the Hyde brand, its UV intellectual property, and select design, sale and aftermarket assets. 

“With this landmark acquisition, Optimarin is consolidating its strong position as a long-established BWTS supplier and expanding its installed base of such systems,” said Optimarin CEO Tore Svanheld.

Hyde’s Guardian ultra-violet (UV) systems are designed for smaller vessels with lower ballast flow rates, such as offshore support vessels, container ships, cruise ships and small tankers. The Guardian system features fully automatic flow regulation, an alarm system for out-of-parameter conditions, and a dose-based algorithm to ensure proper treatment.  

The Hyde name dates back to 1865, when the Hyde Windlass Company was founded in the shipbuilding town of Bath, Maine. It was one of the first companies to enter the ballast water treatment market, before the passage of the IMO requirement to install a BWTS. Hyde was bought by Calgon Carbon in 2010, then by De Nora in 2021, and will now live under the Optimarin portfolio. 

Up until the sale, De Nora was one of the few BWTS vendors that offered both electrochlorination systems (for large merchant ships) and Hyde’s UV systems (for small-to-midsize vessels or lower flow rates). De Nora retains its electrochlorination product line.
