Seawater can contain a wide variety of marine based organisms. Electrolytic Chlorination can be used as a method for killing off the biological matter in the ballast water. The units can be incorporated into ballast water systems on their own, or as part of a series of differing treatment technologies.
Electrolytic Chlorination applies an electrical current to the ballast seawater. The process is likely to generate Chlorine, Sodium Hypochlorite, Sodium Hydroxide, Hydrogen and other chemical compounds within a chamber through which the ballast seawater passes.
In August 2016 an electrolytic unit catastrophically failed on a semi-submersible installation operating on the UKCS (Dimensions: 1376mm x 501mm x 386mm and weighing approx. 330kg). The failure resulted in the commercial loss of the unit, and produced projectile debris which had sufficient force to cause significant damage to surrounding cabling and equipment.
The incident had the potential to cause significant harm to people in the immediate vicinity of the equipment at the time of failure.
