spar upper module docking offshore lifting collision analysis spar platform simulation analysis
In order to assess the possible collision effect, a numerical simulation for the upper module and spar platform docking at the speed of 0.2 m/s was conducted by using the software ANSYS/LS-DYNA, and the time history of the collision force, energy absorption and structural deformation during the collision was described. The purpose was to ensure that the platform was safely put into operation. Furthermore, this paper analyzes different initial velocities and angles on the Von Mises stress and collision resultant force during the docking collision. The results of this paper showed that the docking could be conducted with higher security. The data in this paper can provide useful references for the determination of the upper module’s offshore hoisting scheme and practical construction by contrasting the numerical simulation results of the parameters on the docking collision.
