Abstract
According to the requirement of offshore installations, the corresponding simplified computer simulation model for subsea pipeline-laying process with inline structures has been built. In order to investigate the main parameters and guarantee the structural safety of the subsea pipeline, static and dynamic analyses based on simulations are carried out. In static analysis, the result of the pipe-laying posture and equivalent stress of pipeline under different residual tension is given. In dynamic analysis, the effect of environmental conditions on the installation process is studied. The simulation process can be adopted as the theoretical basis for the offshore installation. By using the simulation, installation efficiency can be improved and the risk in offshore engineering can be reduced. The process of the simulation method can be spread to the realization of other types of large offshore installation activity.
