Study on the Influence of Transverse Load on the Mechanical Response of Submarine Flexible Pipe

Abstract:

Taking 1 year return period wave data statistics of Cheng Dao sea area as an example, the wave-current flow hydrodynamic load acting on submarine flexible pipe was analyzed. According to the actual structure of submarine flexible pipe, ANSYS numerical model was established. Under the combined effect of internal operating pressure and transverse wave-current flow hydrodynamic load, the results calculated by numerical model shows that with the increase of transverse load, the bending deformation of flexible pipe increases linearly, and the stress of flexible pipe is almost constant.
