ECONOMICAL

In addition to killing the invasive aquatic species present in the ballast water in accordance with IMO and other regulatory requirements, the system also offers the ship owner significant savings in maintenance costs through a substantial reduction in ballast tank corrosion.
This is achieved because the percolated reduced oxygen gas sits in the ullage space within the tank thereby protecting the ballast tank and ensuring a longer life for ballast tank coatings, even if the coating has been cracked or compromised in some way.
Tests have shown that corrosion can be reduced by more than 80% in normal operation and this provides significant savings in dry dock maintenance time and repair costs, as well as offering an extension to the economic operating life of a vessel.
These savings are more than enough to pay for the system, its installation and maintenance, many times over during the lifetime of a typical vessel.
