This paper analyzes CALM terminal sensitivity under various operating parameters such as water depth, chain mass, current velocity, wave period, hawser length as well as terminal displacement in different directions, and the impact of tanker presence on the behavior of the riser (lazy S) during unloading/loading operations. The hydrodynamic response characteristics of the tanker and CALM buoy are calculated using ANSYS-AQWA software and the outputs are imported in OracleFlex software for simulation of the probable operating scenarios considering the terminal, tanker, mooring lines and Environmental conditions. The results indicate that the terminal dynamic response is most sensitive to the current velocity changes. It is also concluded that for the riser, when Near offset, an effective tension and for far offset, the bending moment includes critical states. The bending moment at the hang-off the riser and the effective tension at PLEM receive the most impact from the interactive mode of operation between the tanker and the terminal.
