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.
Having pioneered the application, Alfa Laval and PureBallast are the most established choices in ballast water treatment.
Alfa Laval has been involved with ballast water treatment for more than a decade. Besides developing treatment technology, we have provided biological and technical competence on key panels whose role is to develop standards and educate the market.
PureBallast, which was developed in cooperation with Wallenius Water, is a mature system that has long been at the forefront of ballast water treatment. The original system, launched in 2006, was the very first commercially available treatment solution.
More than 1600 PureBallast systems have been sold to date, hundreds of which have already been delivered and commissioned. Hundreds of PureBallast systems have been installed as retrofits, and installations have been performed worldwide at a diverse range of shipyards.
Just as importantly, PureBallast been chosen for a diversity of vessel types: container ships, tankers, bulk carriers, offshore supply vessels, naval vessels and more.
Alfa Laval PureBallast 3 is type approved by IMO according to the revised G8 guidelines and by the U.S. Coast Guard (USCG).
All generations of Alfa Laval PureBallast, current and previous, have IMO type approval. Alfa Laval PureBallast 3 is the first solution to be type approved according the revised 2016 G8 guidelines, which is necessary for any system that will be installed after 28 October 2020. For PureBallast systems installed prior to 28 October 2020, previous type approvals remain valid and no upgrade is necessary.
Alfa Laval PureBallast 3 is explicitly certified for use in all water types: fresh, brackish and marine.
The USCG type approval for PureBallast was issued in December 2016. It allows PureBallast 3 to discharge ballast within United States waters and explicitly certifies the system for use in all water types: fresh, brackish and marine. The type approval testing was performed using the CMFDA/FDA (staining) method and the same hardware, power consumption and flow as the IMO-approved version of the system.
PureBallast 3 can be used for as long as five years from the vessels compliance date (either original or extended). PureBallast 3 is both an accepted AMS and USCG type approved system. If the AMS operation meets a vessel's operational needs, whereas the type approval does not (example given the 72 hours hold-time is a restriction), then the AMS can be used (I.e. system can be operated in IMO mode)
* PureBallast 3 Compact Flex is the newest addition to the product portfolio and currently undergoing the TA process for both IMO and USCG.
Both standard and Ex versions of PureBallast have been certified by the major classification societies.
