Metabolomic profiling differentiates rates of corrosion for mooring chains

摘要

Bio film-exacerbated marine corrosion of metallic materials is an ongoing problem in both onshore and offshore systems. In recent years, inspections of the mooring chains on several floating production units worldwide revealed severe localized corrosion attack. Microbiologically-influenced corrosion (MIC) has been implicated as a cause of chain deterioration. Over the past few years a number of pilot studies and Joint Industrial Projects involving major oil companies, off-shore engineers, universities and chain manufactures has been initiated to investigate the cause of chain deterioration and to evaluate mitigation strategies.
