PREDICTION OF MOTION, WAVE LOAD, AND SLING TENSION OF CRANE VESSELS DURING HEAVY LIFTING OPERATIONS

A computational method for predicting motion, dynamic wave load and sling tension of a crane vessel during heavy lifting operations is proposed. The coupling motion effect between the vessel and the weight being lifted and the viscous damping are taken into account. Solutions for a barge-shaped vessel and a semisubmersible crane vessel are calculated as numerical examples and the results agree well with available experimental data. In addition, a method to evaluate the workability of a crane vessel in given ocean environment is presented.
