PureBallast 3 solutions for offshore oil and gas

For the mobile offshore drilling units (MODUs) and floating production units in the offshore oil and gas industry, as well as the many smaller supply/support vessels, ballast water management is an added headache in an already high-stakes business. We can keep ballast water compliance simple and cost-effective, thanks to flexible Alfa Laval PureBallast 3 technology and the experience surrounding it.

Ballast water management – for offshore as well

The offshore and marine industries differ, but not when it comes to ballast water compliance. As clarified by the MEPC, the Ballast Water Management Convention also applies to mobile offshore drilling units (MODUs) – even when they aren’t self-propelled. That means both ship-type and platform-type vessels, including semi-submersibles (SSVs) and jack-up barges or rigs.

In short: MODUs relocate less often, but they must manage their ballast water when they do. Unless the ballast water is discharged in the same place where it was sourced, MODUs need a safe, reliable and cost-efficient treatment solution like PureBallast 3.

Meet offshore industry needs with PureBallast 3


Drilling and construction

Mobile offshore drilling units (MODUs) and offshore construction vessels are complex operations. Meeting their ballast water management needs demands deep experience and a high degree of flexibility. With solutions like PureBallast 3 Compact Flex, Alfa Laval can provide customization for jack-up barges, jack-up rigs and semi-submersible (SSV) platforms – but also proven, repeatable designs for drillship fleets.


Offshore production

Once the flow of oil and gas is underway, uptime is the key to profitability – both on rigs and on vessels such as floating production storage and offloading units (FPSOs) or floating storage and regasification units (FSRUs). PureBallast 3 solutions can be retrofitted offshore without disturbing operations, and their high reliability means both safety and efficiency. Alfa Laval’s global service network ensures peace of mind 24/7.


Offshore support

The vessels that support drilling and production have limited space – but large demands when it comes to ease and efficiency. PureBallast 3 Compact and Compact Flex minimize footprint and installation costs on platform support vessels (PSVs), offshore supply/support vessels (OSVs), anchor handling tugs (AHTs) and more. Yet the proven UV technology means simple operation and low OPEX in the widest range of conditions.
