PureBallast 3 solutions for tankers

The practicalities of transporting liquid cargo set tankers apart from other vessels. In addition, they pose unique challenges for the choice and installation of a ballast water treatment system. Not only is Alfa Laval PureBallast 3 well adapted to tanker needs, Alfa Laval has the tanker-specific experience and solutions to support the most complex tanker projects.

The choice of tanker customers

The number of customers choosing PureBallast 3 for ballast water treatment on their tankers continues to grow.

Large ballast water flows for KOTC

Kuwait Oil Tanker Company (KOTC) is one of many ship owners choosing UV ballast water treatment over electrochlorination for large ballast water flows. Alfa Laval PureBallast 3 will be installed on vessels throughout the KOTC fleet, including VLCCs with flows of 6000 m3/h each.

Answers for your tanker’s needs

A wide range of system advantages and dedicated technical solutions make PureBallast 3 the ideal choice for ballast water treatment on tankers.

Handling large ballast flows

Your tanker may require hundreds of thousands of tons of ballast water – which means large ballast water flows. PureBallast 3 handles even very large flows with a small footprint and low power consumption, thanks in part to a 1500 m3/h reactor size. Single systems can handle up to 3000 m3/h, while dual systems can be used for coverage up to 6000 m3/h.

Meeting Ex requirements

If your tanker carries volatile cargo, it has to meet the stringent requirements for potentially explosive environments. PureBallast 3 Ex systems are configured according to ATEX and IECEx, Zone 1, IIC and T4, with redundant safety features and lamp cabinets that are located in the safe zone up to 150 m from the reactors they serve.

Installing a system on deck

If your tanker uses submersible pumps, e.g. Framo pumps or the equivalent, you have maximum room for product – but no pump room or existing space for the ballast water treatment system. Alfa Laval has developed a pre-assembled deckhouse solution that makes PureBallast 3 Ex easy to install on deck.

Installing a ballast water treatment system on deck shouldn’t mean problems for your existing submersible ballast pumps. The technical teams for Alfa Laval ballast water treatment systems and Framo pumping systems have developed a solution for providing additional pumping head when PureBallast 3 Ex is installed in a deckhouse.

Ensuring sufficient pump head

If your PureBallast 3 Ex system is installed in a deckhouse, your existing ballast water pumps may not provide enough pressure for effective backflushing. In such cases, Alfa Laval can integrate a booster pump unit (BPU) into the deckhouse. This protects your tanker’s cargo offloading rates without changes to its existing pumps.
