MEPC 84 agenda includes new BWMS approvals
Agenda outlines a final approval application and new or amended type-approvals for ballast water management systems submitted by Denmark and Norway
Documents submitted under the ballast water agenda item for MEPC 84 (27 April to 1 May 2026) set out one application for final approval of an active substance and a series of administration notices covering type-approval decisions and amendments for ballast water management systems (BWMS).
These documents are presented as information for the MEPC and IMO, rather than as proposals requiring technical debate, inviting delegates simply to take note of the material provided.
Denmark has submitted an application for Final Approval under Procedure (G9) for the Blue Ocean Shield Electrolytic Chlorination (BOS EC) BWMS, produced by COSCO Shipping Heavy Industry Technology (Weihai) Co Ltd, and states that the submission’s risk assessment is based on the analysis of treated water from full-scale testing of the BOS EC BWMS model EC-300 at DHI in Denmark. The technology uses side-stream electro-chlorination for ballast water treatment.
Separately, the Danish Environmental Protection Agency and Danish Maritime Authority notified MEPC of their decision to type-approve the OceanGuard Sim BWMS, manufactured by Headway Technology Group (Qingdao) Co Ltd.
The Norwegian Maritime Authority also informed MEPC that it has granted type-approval to the PureBallast 3.5 Ultra and PureBallast 3.5 Ultra Ex, manufactured by Alfa Laval Technologies.
This is an approval update to an earlier type-approved system.
Norway has reported to MEPC an amended type-approval for the Cyeco BWMS, produced by Shanghai Electric Cyeco Environmental Technology Co Ltd, and the submission states that the model range has been expanded to also include explosion-proof models, adding that the 2025 amendment includes the full range of additional models with the suffix ‘Ex’, which can be installed in hazardous areas.
A further Norwegian submission informs MEPC 84 of an amended type-approval for the inTank BWTS, manufactured by Scienco/FAST, a subsidiary of BioMicrobics Inc.
The approval has been amended to also include an alternate TRO sensor and models inTank FITT BWTS and inTank SuperFITT BWTS.
