Hydrogen permeation through cathodically protected and unprotected BS 4360, grade 50D with various surface finishes and coatings was measured over a 12-month period in open seawater and for a subsequent 6 months in marine mud. Cathodically protected, uncoated steel showed the greatest hydrogen permeation, and coated steels showed the least. Nonantifouling coatings showed a rapid deterioration when buried in marine mud, with a significant increase in hydrogen permeation. Overall, the antifouling coating gave the lowest hydrogen permeation in both environments. Results were discussed in relation to possible hydrogen-induced cracking in the use of moveable jack-up offshore oil and gas platforms.
