Abstract
One of the main functions of an OSV is for heavy lifting. Therefore, predicting dynamic loads in various operation conditions is one of the crucial points of the lifting operation of an OSV. To do this, crane-lifting simulation precedes real operation to verify the safety of the lifting operation. This study derives the equations for the motion of a multibody system using a flexible body model for the crane boom based on the finite element in various ocean conditions. The results showed that flexible body models have bigger dynamic factors than do the rigid body models in all cases, which means the flexibility of the crane boom should be considered to accurately estimate the dynamic effect on the OSV lifting simulation.
