Abstract
This paper focuses on the free span of submarine pipelines. The vibration differential equation and dynamic characteristic equation of submarine pipelines subjected to axial force and stress analysis were established, and then got the natural frequency. In order to avoid VIV, the vortex shedding frequency and reduced velocity was used as control parameters, and the allowable span length of submarine pipelines was thus derived. By using calculation example, to analyze the influence of flow velocity, axial force, and pipe dimensions on the natural frequency and allowable span length. The general method for determining was given. The result indicates that the allowable span length of submarine pipelines decreases with flow velocity, compression, and increases with an increment in tension.
