Safe for Ballast Tanks

Comprehensive corrosion test = No impact on corrosion rate

Ballast tanks contains some of the major structural elements of a modern vessel. Double hull tankers for instance, carry most of the longitudinal strength in the ballast tanks. Corrosion in these tanks represents a serious risk for the vessel due to loss of structural integrity and a potential significant investment in terms of repair or re-coating of tanks.

OceanSaver Ballast Water Treatment System MKII has been subjected to comprehensive, corrosion and coating tests to ensure that it will not damage ballast tanks coating systems. Two full-scale shipboard tests were carried out over a duration of more than 12 months. These were supported by a 6 month laboratory test.

Independent test engineers = Reliable results

All tests were undertaken independently by corrosion engineers and coating systems experts at DNV’s Corrosion Laboratories in co-operation with Safinah, a UK coating consultancy firm. Through these tests, the OceanSaver MKII Ballast Water Treatment System demonstrated that it would not harm ballast tank coating systems.

Conventional electro chlorination systems injects a high TRO dosage increasing the corrosion rate inside the ballast tanks. OceanSaver MKII patented cell technology allows the system to inject a safe maximum of 2.5 ppm hypochlorite into the ballast tanks.

OceanSaver have received statements from several leading ballast tank coating manufacturers stating that the injected dosage will not affect coating performance in accordance with the IMO PSPC rules for Ballast Water Tanks.
