Hyde Marine supplies first ballast water treatment system installed on a dedicated Great Lakes vessel

7/24/2012
Hyde Marine Inc. has supplied the first ballast water treatment system on a dedicated Great Lakes vessel. The Hyde Guardian Model HG60 has been installed on the M/V Ranger III, a 128 passenger ferry providing service to Isle Royale National Park in Michigan. Built in 1958, the 165-foot-long Ranger III is the largest piece of moving equipment the National Park Service owns and operates.

The Park Service is currently exempt from having to install a ballast treatment system on this vessel because it operates in one captain of the port zone under U.S. Coast Guard rules and has the freshwater fleet exemption from EPA (33 CFR 151.2015  (b) and EPA VGP 2.2.3.11). The Park Service conducted a review of available type approved treatment systems and voluntarily installed the Hyde Guardian to meet multiple objectives, including:

• Protection of park waters from accidental aquatic invasive species transfers during Ranger III ballast discharges;

• Prevention of zebra mussel introduction via the Ranger III from park waters to the Houghton Shipping canal where none are currently detected;

• Producing a report on IMO ballast technologies available for small ships; and

• Support of research and testing to enhance the ability for small ships to implement BWT and provide a test platform for compliance test development.

According to Phyllis Green, superintendent, this milestone in Great Lakes protection is a result of support from the Great Lakes Restoration Initiative. “We are pleased that the Ranger III is the first commercial freshwater vessel in the Great Lakes with a permanent BWT system on-board,” says Green in a Hyde Marine press release. Ongoing support from the Restoration Initiative is expected to help the Park Service and other agencies continue to find treatment solutions for the larger ships of the Great Lakes freshwater fleet.

Treatment system selection was based on IMO type approval, ability to operate in Lake Superior’s fresh water and cold conditions, as well as a number of technical and ship specific details. UV-based treatment was found most suitable because the short route between the mainland and the park would provide insufficient treatment holding time for many biocides. The Hyde Guardian System was successfully installed with minimal disruption to the ship’s schedule and without having to dry dock, the company says.

The chemical-free Hyde Guardian is comprised of automatic backwashing depth filtration and powerful UV disinfection, says Hyde Marine, a wholly owned subsidiary of Calgon Carbon Corp. The filter and UV are used during ballasting, and the water receives a second dose of UV prior to discharge. The system offers a compact, modular design, the company says, with low power consumption, low-pressure drop, and simple, fully automatic operation, making it a technically attractive solution for any type and size of vessel.

Hyde Guardian received IMO Type Approval in April 2009 and was the first BWT system accepted into the U.S. Coast Guard’s Shipboard Technology Evaluation Program (STEP).  Calgon Carbon’s UV Technology Division and Hyde Marine received ISO 9001:2008 accreditation from the registrar Det Norske Veritas and the ANAB National Accreditation Board in 2010.

Hyde Marine joined the Isle Royale National Park and the Great Lakes shipping community in a ceremony on June 28 at the Isle Royale National Park Headquarters in Houghton, Mich., to dedicate the installation of the Hyde Guardian unit.
