Techcross, the Korean manufacturer of ballast water management system (BWMS), confirmed that its full-flow electrolysis ElectroCleen system (ECS) has been granted compliance with revised IMO guidelines by the Korean government.

The certification of compliance with the IMO’s Resolution MEPC.300(72) for the Approval of Ballast Water Management Systems (BWMS Code) means that all of Techcross’s BWMS systems employing direct and indirect electrolysis technologies are compliant with the IMO Resolution (the Revised G8).

Techcross also confirmed that its indirect electrolysis BWMS method, ECS-Hychlor, was awarded compliance by class society DNV GL on behalf of the Norwegian Maritime Authority in February.

All vessels installing a BWMS after 28 October 2020 need to comply with the international BWMS Code.

Techcross also noted that the System Design Limitations (SDL) of the system had been extended during the process of undergoing compliance testing. The freshwater holding time for Techcross ECS was reduced from 48 hours (as stated in the earlier USCG type approval) to 23 hours. The system also successfully enhanced the operation temperature in cold water to more than or equal to -2, in addition to improving the feed salinity to 1 PSU or above from 1.5 PSU with mixing solution involved for fresh water (less than 1 PSU).

The company noted that its original direct electrolysis solution, ECS A type, is undergoing renewal tests for USCG type approval to address some limitations. Although only 96 ships are equipped with ECS A type, Techcross is willing to take responsibility for all of its products they have sold despite considerable time and cost.
