Resumo

This work describes the on-bottom roughness analyses performed for the repurposing of two gas export
pipelines in Brazilian coast for conditions out of original design premises, as well as the assessment of a lateral
buckle identified in one of them. The main aspects of the employed methodology are presented, followed by their
results. The importance of these analyses in a repurposing context is also discussed.
