Japanese ballast water treatment manufacturer Miura now has two ballast water treatment systems type-approved by the US Coast Guard, lifting the total to 31 systems approved by the US regulator
The Coast Guard Marine Safety Centre has issued its 31st US Coast Guard Ballast Water Management System Type Approval Certificate to Miura Co., Ltd., after a detailed review of the manufacturer’s type approval application determined the system met the requirements of 46 CFR 162.060.
The treatment principle for the Miura HK-(E)R consists of filtration and UV treatment during uptake and UV treatment during discharge. This approval covers models with maximum intake treatment rated capacities between 200 m3/hour and 900 m3/hour.
The USCG type-approval lists the operational limitations as:
The USCG also stipulates that the Miura HK-(E)R BWMS is not approved for fitment on US-flag vessels and is not approved for installation in hazardous locations on a US-flag vessel, but may be installed in hazardous location on non-US flag vessels.
There are now only nine BWMS left on the USCG list of systems under review. This includes four BWMS that have been previously type-approved and have been re-submitted due to changes in technical specification.
