The oil and gas extraction in deep waters by Petrobras has been expanded progressively in the recent years. In this condition, oil and gas can be extracted by Jacket type and semi-submersible platforms, which are connected to the wells through flexible risers. These components are constituted of a multilayer system with internal and external coatings made of polymers. On inspection of these risers, scratches and a significant reduction of the riser protection layer were observed. These damages were found to be related to the relative movement of the pipe in the area of the touchdown point (TDP). In order to reduce this problem the risers have being coated externally with plaques of polyurethane. High chemical inertia and good mechanical and...
