Abstract: A dynamics response model are established using hydrodynamic analysis software OrcaFlex and referring to cable cross section design of Wenchang umbilical cable and operation environmental parameters to simulate the dynamic response of J-tube pull-in installation of the main platform for the umbilical cable under different wave directions. Finally, some instructive notices and mechanical properties during umbilical tie-back were put forward based on related modeling results. The hydrodynamic analytical result shows that the speed of the winch and the change of wave directions have very important effects on the process of umbilical cable pull-in through J-tube; the position where umbilical cable bends badly is where the von mises stress changes obviously as well, but the stress is still less than that permitted by API 2RD, and it can satisfy the request by the engineering safety.

Key words: umbilical cable, OrcaFlex, hydrodynamic analysis, different wave directions
