Corrosion Under Walkways on Oil Tankers

During the main hull survey of an oil tanker, it was noted that deep spots of grooving corrosion had taken place under the walk ways, which is an almost inaccessible area, when the walkways are in place. The original plate thickness was 15 mm, but several grooved and corroded areas were found with only 5 mm of plate thickness; extending in the transverse direction of the deck.
