Crane Modeling and Simulation in Offshore Structure Building Industry

Namkug Ku, Sol Ha, and Myoung-Il Roh

Abstract—To increase the lifting capacity and minimize the cost and time for building a ship and offshore structure, block lifting with multi-cranes becomes more and more danger. In this paper, therefore, dynamic response analysis of the multi-cranes is performed for block lifting operation. By this simulation, one can confirm the dynamic effects, such as dynamic motion and load, to prevent fatal accidents during the multi-crane operation. The crane system consists of several bodies. These bodies are connected with various types of joints and wire rope. To carry out the dynamic simulation, therefore, the crane system is modeled as a multi-body system. There are several types of crane, such as a goliath crane, jib crane, and floating crane, etc. Among them, the floating crane is operated on the sea water. Therefore the hydrostatic force and linearized hydrodynamic force are considered as the external forces acting on the floating crane. Using the dynamics simulation program developed in this paper, a dynamic response simulation of several cases of block lifting with multi-cranes are carried out, and the simulation results are validated by comparing them with the measured data from the shipyard. Moreover, the simulation results can be applied to the structural analysis for evaluate the dynamic effects on the block.

Index Terms—Dynamic simulation, modeling and simulation, multi-body system, large scale manufacturing, structural analysis.
