The new system BOS Natural Ballast set to launch at the SMM trade fair in Hamburg has been engineered to ensure that ballast water discharge standards are met at all times during the uptake and discharge.

Generally, most ballast water systems involve methods of filtering off bacteria and pathogen cells larger than 50 microns in the first stage, and then follow by the processes of actively killing the remaining bacteria and pathogens with treatment options such as UV light, electrochlorination, deoxygenation, heating/pasteurization, injection of active substances, for example.

Typical BWTS assumes operational compliance once type-approved, but this may not be true since ships take ballast water from all corners of the oceans. The BOS Natural Ballast system measures and records all ballast water management parameters continuously in order to verify that the ballast water management system meets the ballast water discharge standard at all times.

The IMO has recommended in its guidelines that a “more exhaustive list of standard methods and innovative research techniques be considered” in anticipation of the evolution of better methodologies. The gold standard of discharged ballast water is that it must comply with the D2 standard.

The first of its kind Bos Natural Ballast system uses a ballast water measuring and monitoring feedback methodology to ensure compliance to D2 standard without the increased GHG emission and enormous CAPEX/OPEX.

BOS Natural Ballast has a small footprint and is easy to retrofit/install without the need for the ship to stop operation.
