PureBallast 3 solutions for bulkers

Bulkers differ from other vessels in their ability to transport both dry and liquid cargo – which they often load and unload at different speeds. Their ballast water flow needs can be very small or very large, but they may not be the same during ballasting and deballasting. Alfa Laval PureBallast 3 offers solutions for all bulker types, and Alfa Laval has the bulker-specific experience to support the most complex bulker projects.

  • Optimal dimensioning for differentiated bulker flows
  • Lower CAPEX for ballast water treatment system
  • Reduced OPEX and system footprint

Adapting to bulker flow needs

Bulkers often load their cargo at twice the rate they unload it, which means deballasting occurs at twice the ballasting speed. The PureBallast 3 bulker-fit configuration addresses this by dimensioning the reactor and filtration capacities for differentiated flows. Not only does it reduce OPEX and the already small system footprint, it also removes a significant amount of CAPEX.

Star Bulk to install PureBallast 3 bulker-fit configurations

Six of Star Bulk’s vessels already have PureBallast 3 systems, and now 37 of its Supramax, Ultramax, Panamax, Kamsarmax and Post Panamax bulkers will be retrofitted with bulker-fit configurations. “This is the appropriate solution in meeting the demanding trading requirements on these vessels,” says Nicos Rescos, Chief Operating Officer.

Bulker-fit configurations in the Briese Group fleet

Briese Group has selected PureBallast 3 for roughly 100 vessels, including bulk carriers that will be equipped with bulker-fit configurations. “The bulker-fit configuration was a good compromise for our bulkers’ needs, since it combines a smaller footprint with lower CAPEX and OPEX,” says Adrian Beckmann of the Newbuilding and Project department.

Answers for your bulker’s needs

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

Handling large ballast flows

Your bulker may require up to 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.

Simplifying retrofit installations

Existing bulkers need to be retrofitted with ballast water treatment systems by the time of their next renewal survey. However, they seldom have space allotted for it in their design. PureBallast 3 Compact Flex handles most flows and is flexibly built with loose components, making it the ideal system for saving space and resolving bulker retrofit challenges.

Skid-mounted for smaller bulkers

If you have a smaller bulker, there’s no reason to make big work of installing a ballast water treatment system. PureBallast 3 Compact is a convenient, skid-mounted solution that’s specially designed for smaller bulkers and other vessels with flow needs of 32–300 m3/h. Delivered as a skid-mounted module, it minimizes both footprint and pipework.

Minimized holding time in US waters

Many bulkers operate in coastwise service in USCG-regulated waters. If you have a relatively short time between United States ports, long ballast water holding times aren’t an option. PureBallast 3 now has a minimized holding time of just 2.5 hours – which is only needed when crossing between Captain of the Port Zones.
