Techcross ECS wins new G8 type-approval

Posted on:

Ballast treatment system maker Techcross has gained South Korean government type-approval under the new BWMS Code G8 procedure for its ECS treatment system. The same approval was already granted by the Norwegian government in collaboration with DNV GL last February to ECS-HYCHLOR, another system developed by Techcross. With the issuance for ECS from the South Korean government, all Techcross systems employing direct and indirect electrolysis technologies are now approved to the new G8 standard.

Unlike the previous IMO G8 certification, BWMS Code features a new category called System Design Limitation (SDL). This category specifies the operational condition of the system. Techcross ECS reduced the freshwater holding time from 48 hours (as stated in the earlier USCG type approval) to 23 hours. In addition, the system successfully enhanced the operation temperature with 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).

Following the 2018 changes to the 2004 Ballast convention all systems installed on ships on or after 28 October 2020, must obtain the new type-approval. With the USCG type approval obtained in 2018 and the new approval, Techcross systems can be used without restriction in all ports around the world.

Techcross has also advised that its ECS A type, the initial system from the company is in the process of renewal tests for USCG type-approval to address some limitations. Although there are only 96 ships equipped with ECS A type, Techcross said it is willing to take responsibility for all of products they have sold despite considerable time and cost.
