• 英文摘要： A method for the dynamic analysis of the sernisubmersible platform and its mooring system is pre-sented. First of all the catenary equations for the single and the combined mooring lines were derived. Andthen, based on the design requirements, the initial conditions of the mooring system were determined.Finally, the dynamic responses of the platform and its mooring lines subjected to the arbitrary time-varyingloads such as those due to waves, wind, and current were studied and the applicability of the mooring lineswas checked. On the basis of the algorithm of the Newmark direct integration method, a general computer pro-gram was developed and the nonlinear equations of the platform motions coupled with the forces in moor-ing lines were solved. All the results obtained are reasonable and the theories presented should be usefulin practice.
