The IMO Type-Approved Balpure ballast water treatment system from Severn Trent De Nora has become one of the first ballast water treatment technologies to receive the United States Coast Guard’s (USCG) Alternate Management System (AMS) certification.
AMS certification identifies an IMO Type-Approved system that meets the USCG requirements. Ships are required to have onboard ballast water treatment systems that prevent invasive species from being shipped into U.S. waters. The AMS certification has specifically approved the use of BALPURE, which complies with IECEx Classification, in hazardous areas on board vessels. Severn Trent De Nora has sold and delivered 20 BALPURE units since it received its IMO Type Approval in July 2011.
“The BALPURE team has been working tirelessly to obtain the various approvals required for the system to be accepted for use on board international trading vessels. This new AMS certification of Balpure is a significant milestone for us as it signifies the system is now permitted to be used on board vessels trading in U.S. waters that are required to comply with the USCG Final Rule. This achievement solidifies Balpure’s position as a robust and reliable solution that shipping companies can trust,” said Marwan Nesicolaci, vice president, global sales and marketing, Severn Trent Services. “With this most recent recognition, we plan to increase our manufacturing capability to meet increasing demand.”
As part of the USCG’s review process for AMS, Severn Trent De Nora submitted Basic Approval documentation, Final Approval documentation, shipboard test data, Operations & Maintenance manual, detailed drawings for each Balpure System (flow sheets, P&ID, general arrangement), and Bill of Materials (BoM) for each system including vendor technical literature and certification for all equipment.
The AMS submission involved a concurrent submittal for Type Approval to the USCG. This is being reviewed in parallel and will be held to different approval standards than IMO standards, including ETV test protocol by USCG certified test facilities. USCG has not published all the requirements for the Type Approval review process which will be determined in the next few years.
Balpure features electrolytic disinfection technology, ease of installation and operation, minimal maintenance and low operating costs for both retrofits and newbuilds. Its slip stream treatment approach, where approximately one percent of the total ballast water flow is used to generate the hypochlorite disinfection solution, enables remote mounting away from the main ballast line. The slip stream treatment approach, coupled with a design that requires treatment only during the uptake of the ballasting cycle, offers significantly reduced power requirements when compared to competing technologies – ensuring low operational costs. Balpure offers a virtually maintenance-free approach to ballast water treatment through the use of proprietary self-cleaning electrodes that eliminate the need for time-consuming chemical and mechanical maintenance.
