Abstract In this paper, the discrete event/discrete time simulation of the block erection by a floating crane is performed for the purpose of estimating the motion of the floating crane and the block and also calculating the tension of the wire rope between the two. At this time, the dynamic equations of motion of the floating crane and the block are set up for considering the 6-degrees-of-freedom floating crane and the 6-degreesof-freedom block based on multibody system dynamics. The nonlinear terms in the equations of motion are considered. In addition, the nonlinear hydrostatic force, the linear hydrodynamic force and the wire rope force are considered the external forces. Finally, we analyze the engineering effects of erecting the block by using the floating crane.
