The Buckling Simulation of Drilling Riser in Shallow Waters under the Combined Effects of Wind, Waves and Currents

Force applied to riser is analyzed. As for wind, waves and currents, the relationship between their load and their height and depth is work out. The relationship was applied to oil field engineering in shallow sea. Riser buckling response and stress distribution in the harshest conditions were simulated on Workbench and the critical buckling load deformation characteristics and stress distribution were obtained. The structural weaknesses was pointed out. Corresponding to each order resonance speed, the frequency was calculated with the natural frequency.
