Hyde ballast water management system gets Type Approval
Hyde Marine, Inc. has received final Type Approval for the Hyde Guardian Ballast Water Management System. Issued by Lloyd's Register on behalf of the U.K. Maritime and Coastguard Agency, the Type Approval Certificate confirms compliance with guidelines contained in IMO resolution MEPC.174(58). Thes approval covers the complete range of Hyde Guardian systems with capacities from 60 cu.m/hr to 6,000 cu.m/hr, allowing Hyde to satisfy the requirements of all vessel types and sizes.
Tom Mackey, Hyde's Chairman, hailed the development as "a major milestone for our company."
Hyde completed all required land based testing at Netherlands Institute for Sea Research (NIOZ) in the spring of 2008. Shipboard testing, spanning a six month period during 2008, was conducted aboard the cruise ship "Coral Princess", by scientists from the University of Maryland Chesapeake Biological Laboratory (CBL). Tests were conducted in full accordance with the IMO G8 Guidelines and demonstrated that the performance of the Hyde Guardian exceeds the IMO D2 performance standard and that it can also meet more stringent proposed U.S. Federal and State of California standards.
The Hyde Guardian treatment process combines automatic back-flushing disk filtration during ballasting and powerful, medium pressure UV disinfection during both ballasting and deballasting to inactivate marine organisms.
No chemicals or active substances are used or produced in the treatment process or for maintenance of the system.
Suitability for shipboard applications has been well proven aboard the "Coral Princess", operating continuously since June 2003, and the Celebrity "Mercury", in service since January 2007. Both vessels have been allowed by the State of Washington to discharge treated ballast water into state waters.
In October 2008, the "Coral Princess" was the first ship accepted into the U.S. Coast Guard Ship Technical Evaluation Program (STEP), allowing it to discharge properly treated ballast water anywhere along its normal routes in US waters for the life of the ship.
After five years of operation, all STEP and IMO G8 testing was performed with the originally installed UV lamps, quartz sleeves, and filter disks --a demonstration of the Hyde Guardian's robust design and efficient automatic self-cleaning process.
Hyde Guardian systems are available as components for retrofit into the space available aboard existing vessels, as was the case with the first two systems installed. They can also be delivered as compact, skid mounted units,for new vessel construction projects.
Hyde Marine supplied six Guardian Model HG300-S systems to the U.K. Royal Navy in December 2008. They systems will be installed on two new Royal Navy CVF Future Aircraft Carriers, which each have three completely segregated ballast systems.
The Guardian design requires no chemicals for operation or maintenance. Low pressure drop allows for use of existing ballast pumps and ensures minimum reduction of ballast flow rates. The Guardian is totally automatic and easily interfaces with the ship's control system. The system can be made explosion proof for installation in hazardous environments, making it suitable for tank vessels and all other shipboard applications as well as for land and barge based installations.
