Metallic strips flexible pipe has been favored in the offshore pipelines engineering for its good corrosion resistance, high strength, easy installation etc. This new composite pipe can be regarded as promising alternative for submarine pipelines. In this paper, the cross-sectional design process for this specific kind of pipe is illustrated. Three formulas for calculating the individual strength capacities of the pipe when subjected to internal pressure, external pressure and pure bending are presented for initial screening assessment. And then a case study for an 8 inch metallic strip flexible pipe based on a shallow water application is carried out. Several FE models are established by using commercial software ABAQUS to verify the designed cross section. The two methods presented could be used to assess the structural performance of the pipe in the early design phase, which might be interesting to the manufacture engineers.
