Hyundai Heavy Industries’ EcoBallast filtration and UV-based model and Miura of Japan’s filtration and UV-based HK- (E) C model ballast water treatment systems have both successfully achieved US Coast Guard type-approvals
The EcoBallast model is the second Hyundai Heavy Industries ballast water treatment system (BWTS) to be given US Coast Guard (USCG) type-approval status. In 2018, HHI’s HiBallast filtration, electrolysis/electrochlorination BWTS was given USCG type-approval. The HiBallast model was also given the explosion proof (46 CFR 111.105) type-approval, allowing it to be installed in hazardous locations on US-flag vessels.
This status has not been given to the latest HHI system approved. The USCG type-approval certification for the EcoBallast BWMS notes that the 250-2,160 m3 per hour flow system cannot be used in hazardous locations on foreign-flag vessels. Other operational limitations include:
Furthermore, the USCG states “This BWMS does not meet the requirements of 46 CFR Subchapters F and J and may not be installed on a US flag vessel.”
The second BWTS to be approved in recent weeks is the Japanese Miura HK- (E) C model ballast water treatment system. This is a filtration and UV system rated between 160 and 900 m3/hour. The certification testing process was undertaken by DNV GL.
Like the HHI EcoBallast BWMS, the USCG type-approval certificate does not include US flag vessels (46 CFR Subchapters F and J restrictions) or hazardous areas. Operational restrictions include:
The addition of HHI’s EcoBallast and Miura’s HK- (E) C model to the list of USCG type-approved systems brings the total certified BWTS to 23.
