The International Association of Classification Societies (IACS) Guidelines for Coatings Maintenance and Repairs describes protocols for ballast tanks surveys. The Guideline calls for surveyed ballast tanks found to be in FAIR or POOR condition to be restored to GOOD condition. As ships age, this restoration becomes increasingly expensive, running into the millions of dollars. NEI's ballast tank deoxygenation system is designed to maintain a GOOD rating throughout the life of the vessel without any need for coating restoration or steel renewal.
BALLAST TANK MAINTENANCE COSTS ARE REDUCED
TO PRACTICALLY $0
NEI has recently completed a comprehensive Life Cycle Cost Analysis of the Venturi Oxygen Stripping™ system as a corrosion protection measure. Please follow the link below to view a copy of this report.
It is important to note, many of the experimental ballast water treatment technologies being tested employ chemicals that are strong oxidizers that can increase corrosion rates in ballast tanks, and rapidly degrade ballast tank coatings. In May 2005 the International Ship Structure Committee (ISSC) published a report called "Deterioration of Structural Integrity Due to Chemical Treatment of Ballast Water". It is attached here in full for your reference.
