Quantitative Coating Quality Assessment on an Offshore Platform

Early signs of coating degradation were investigated by impedance measurements at 40 locations on a docked, jacketed offshore platform 1.5 and 2 years after full coating renewal. The platform coatings were evaluated in comparison to 38 reference samples with partial and complete coating systems that were aged at the shoreline for 1.5 years and subsequently tested in the laboratory in dry and wet states. The quantitative coating quality approach based on log Z measurements at 0.1 Hz and subsequent statistical analysis has provided means to quantitatively assess coating degradation in situ and identify a platform site with limited coating durability.
