The internal corrosion assessment of a typical transportation system has been presented. A system of Pipelines has been designed that will convey hydrocarbons from a land based process facility to an offshore loading platform where it will be exported via bulk carriers. The candidate material selected carbon steel L450 was found to be satisfactory as it showed effective resistance against the internal environment of the pipeline. Sour corrosion has been examined to be the most probable form of corrosion to occur within the pipeline given the data provided. The corrosion allowance selected was found to be sufficient within the design life to provide the integrity of the pipeline as the corrosion rate was computed as 0.1mm/yr (Upset/worst condition).
