Piggyback pipeline is defined as a pipeline system composed of one big pipe and one or several small pipes. Based on the theory of wave-current interactions and physical model test, the hydrodynamic characteristic of submarine piggyback pipeline in wave-current coexisting field (both regular and irregular waves) was investigated. The so-called modified diameter method suggested by authors is used for analyzing the in-line hydrodynamic coefficients of such kind pipeline, which is well related to KC number. The comparison of tested data in regular and irregular waves shows that in the region of 90 > KC > 20, the results in these two cases can be unified. The effect of water depth was analyzed in detail. The relationship between Cd, Cm and Kc, which is based on the results of present research, may be used as a reference for engineering application.
