Abstract：The failure of submarine pipelines due to corrosion defects has an increasing tendency in recent years. In order to assess the failure risk when corrosion occurs, we present a review of the strength assessment procedure of DNV-RP-F101. The parameters which will impact on burst pressure are studied. And the relation between DNV-RP-F101 and DNV-OS-F101 is discussed. Based on the calculation results, the following conclusion can be made. Among the key parameters, the inspection accuracy has the greatest influence on the strength assessment results. When certain condition is satisfied, the ratio of yield to tensile is negligible.
