Ecochlor has announced it has received IMO BWMS Code type-approval for its EcoOne and EcoOne Hybrid models from the Norwegian Maritime Authority
As Ecochlor predicted at the launch of its EcoOne and EcoOne Hybrid, the models have now received IMO BWMS Code type-approval. Ecochlor is confident the new BWMS models will receive US Coast Guard type-approval by the end of 2021.
EcoOne BWMS was tested extensively to ensure it works effectively as a single-step system using chlorine dioxide (ClO2) treatment technology, without a filter and in all operating conditions in brackish and marine waters.
DNV was the independent laboratory (IL) and took overall responsibility for the entire process of evaluation, inspection, testing and submission of all type-approval applications for the system.
Land-based biological efficacy tests were undertaken by the Golden Bear Research Center (GBRC) in California, USA.
The shipboard tests, undertaken by DHI as sub-laboratory, were completed to test the biological efficacy and related shipboard operational performance of the EcoOne BWMS on board commercial vessels. This testing was performed on two vessels owned by Maran Tankers, a VLCC and an Aframax, during typical voyages.
Ecochlor vice-president of operation Pete Thompson said, “Our team is very excited to bring these new and innovative BWMS to market. We have worked diligently over the last 18 months along with DNV, Maran Tankers, Golden Bear and DHI to test the EcoOne BWMS and EcoOne Hybrid BWMS to the highest standards possible in compliance with IMO testing requirements and to ensure the operational reliability that is expected from every single Ecochlor system.”
Ecochlor now offers three different BWMS products:
Ecochlor vice president of business development Andrew Marshall explains why ClO2 is particularly well-suited as a filterless BWMS option, “ClO2 technology is not affected by suspended sediments or turbidity. Therefore, filtration is not necessary to remove sediments prior to treatment, unlike UV technology. Additionally, ClO2 technology primarily reacts with living organisms (rather than reacting with all organic matter) and does not require significantly increasing the dose to effectively treat the ballast water.
