OceanSaver option:
Reduced corrosion and oxidation of ballast tank coatings - reduction in TCO
OceanSaver BWTS stands out among Ballast Water Treatment Systems for its commitment to protecting ballast tank coatings, demonstrating its performance and undertaking tests.
Reduced corrosion
The OceanSaver BWTS has been subject to comprehensive, appropriate tests to ensure that it will not damage ballast tank coating systems, and has proven that it will not hinder shipowners attempts to meet the requirements of the newly developed and implemented Performance Standard for Protective Coatings (PSPC).
Analysis of ballast tank coating assessments with and without treatment by the OceanSaver system - confirming reduced creep corrosion on test panels exposed to treatment.
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. 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 BWTS demonstrated that it would not harm ballast tank coating systems. Even on scratched surfaces with exposed steel, the OceanSaver treatment showed significantly decreased creep corrosion. Over the test period, a reduction in the consumption of anodes of 11-15 per cent was gained when using OceanSaver BWTS.
Compliant with the intentions of the Performance Standard for Protective Coatings
The PSPC aims to achieve a fifteen year target life for ballast tank coatings. The comprehensive OceanSaver test program confirms that coatings are protected and thus OceanSaver is strengthening the intention of the PSPC.
OceanSaver's impact on the Performance Standard for Protective Coatings
Ship's ballast tank protective coating systems may present premature failure leading to rapid corrosion of unprotected steel, making repair extremely difficult and costly. The standard of coating applications in newbuildings has therefore become the focus of international regulations.
