(NORTH HAVEN, Conn.) — Ecochlor has completed land-based and shipboard testing for the filterless EcoOne ballast water management system (BWMS) in preparation for an application for U.S. Coast Guard and International Maritime Organization BWMS code type approvals.
DNV was chosen to act as the independent lab (IL) throughout the entire process and has been responsible for the evaluation, inspection, testing oversight and submission of the EcoOne BWMS type approval applications.
The land-based biological efficacy (BE) testing was undertaken by the Golden Bear Research Center (GBRC) in California. GBRC performed the tests, analyzed samples, and managed test results in the format required by the IL. Whole effluent toxicity testing was also performed successfully as part of the land-based trials.
The shipboard testing, undertaken by DHI as sub-laboratory, was completed to evaluate the BE and related shipboard operational performance (OP) of the EcoOne BWMS on board a commercial vessel. DHI performed the shipboard tests, analyzed samples, managed test results in the format required by the IL. Due to global pandemic restrictions, shipboard testing was allowed to be performed on two commercial vessels owned by Maran Tankers, a VLCC and an Aframax, during their typical vessel voyage routes within the six-month testing period.
The filterless EcoOne BWMS is a one-step treatment process utilizing ClO2 alone. Vessels operating this system can operate anywhere in marine and brackish waters and with no restrictions on temperature or turbidity.
The EcoOne Hybrid BWMS has a dual mode of operation with both filtration and ClO2 or ClO2 alone. This system will allow shipowners to operate their BWMS either with or without a filter. This option will be suited for shipowners seeking the flexibility of unrestricted operation in freshwater globally, with the convenience of a no-filter system. Vessels that already have an Ecochlor BWMS with filters installed can upgrade to the Hybrid option with minimal cost.
The Ecochlor BWMS not only meet and exceed environmental regulatory standards: these systems have a reputation in the industry as one of the most dependable in the market with a product line that offers one-stop BWMS options to the shipowner for any vessel, on any trading route, in any port, worldwide.
