Abstract

The SCORCH JIP conducted a study on corroded/pitted chain links that were recovered from a floating storage offloading system based in West Africa. The large pits observed, sometimes leading to reduction in diameter of the order of 35%, most likely can be attributed to microbiologically influenced corrosion. The effective breaking loads were ∼ 80-90% of the catalog minimum breaking load despite the large reduction in cross- sectional area. The corrosion rates deduced from the observations are significantly higher than the values recommended in existing codes and Class Rules. The long-term corrosion rate appears to follow a Frechet distribution instead of a Gumbel distribution in agreement with the latest findings in the field of corrosion. This is an abstract of a paper presented at the Offshore Technology Conference 2012 (Houston, TX 4/30/2012-5/3/2012).
