Physical model experiments are conducted to study the hydrodynamic characteristic of submarine piggyback pipeline under regular wave-current and irregular wave-current actions.Based on Morison equation,drag coefficient CD,inertia coefficient CM and lift coefficient CL(C+L,C-L) are obtained with the method of "equivalent diameter".In the experiments,effects of current ratio Uc/Uw,gap ratio between the large pipeline and the seabed e/D and spacing ratio between the large pipeline and the small pipeline G/D on the hydrodynamic coefficients of submarine piggyback pipeline are investigated.The results indicate that the hydrodynamic coefficients decrease with the increase of Uc/Uw.The effect of the seabed on the hydrodynamic forces on the piggyback pipeline is pronounced for e/D0.5.CD,CM and C+L decrease with the increase of e/D,and C-L increases with the increase of e/D.In addition,the interaction between the large pipeline and the small pipeline is not negligible.CD,CM and C-L decrease with the increase of G/D,and C+L increases with the increase of G/D.
