Alfa Laval PureBallast 2.0 type-approved by USCG

The US Coast Guard Marine Safety Center announced it has issued the 39th US Coast Guard Ballast Water Management System (BWMS) type-approval certificate to Alfa Laval Tumba AB, 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 of the PureBallast 2.0 BWMS is based on filtration and UV treatment at intake and UV treatment at discharge. This approval covers six models with maximum treatment rated capacities of between 250 m³and 2,500 m³.

The USCG states the operational limitations for PureBallast 2.0 as:

• Salinity: >1 PSU
• Temperature: -2°C to 40°C
• Hold time: >22 Hours
• UV intensity at 100% TRC: 780 W/m²
• UV intensity at 50% TRC: 375 W/m²

The USCG certification also stated that the PureBallast 2.0 BWMS has not been verified to meet the requirements of 46 CFR Subchapters F and J. This means the BWMS may not be installed on a US-flag vessel. The explosion-proof version, PureBallast 2.0 Ex, may be installed in hazardous locations on a foreign-flag vessel subject to approval of the foreign administration.

The USCG had already given type-approval to the latest third-generation PureBallast 3 in 2019. The granting of type-approval for the second generation will allow vessels with the earlier generation system to trade in US waters without hindrance.

Meeting US Coast Guard regulatory requirements is vital for vessels to trade in US waters. Find out more about the opportunities and pitfalls in US trade at the Tanker Shipping & Trade, Americas, virtual conference on 16 February 2021. Click here to register.
