Longterm offshore corrosion protection solution proven by laboratory and field experiments
Corrosion tests were performed using a composite coating reinforced with glass platelets. Its viability as a remedy for corrosion issues in the marine industry was investigated through field and laboratory tests.
The project aimed to correlate the performance of a marine vinylester coating reinforced with
glass platelets, when exposed in a natural service life environment versus that when tested
in an accelerated environment.
Replicating natural exposure in an artificially simulated manner is a challenging task due to the various factors that induce corrosion
in the natural environment. For the natural exposure, two in-service vessels coated with this
marine coating were selected to test its performance. Both vessels were coated for 10 and 15
years without any reapplication. After testing took place, it could be said that the impedance values of the vinylester coating reinforced with glass platelets for both the accelerated and natural exposure were atleast 2
orders of magnitude higher than the minimum industry standard requirement even after 15
years of natural exposure.
