Analysis of Dynamic Cable Load-Out Process from Whart to Cable Transportation Barge Based on OrcaFlex

To investigate the loads on the cable during the dynamic cable load-out process from wharf to cable transportation barge, a survey of the entire cable load-out process was conducted. Influence of different times, locations and tides on the cable was studied, and catenary shape of the cable under corresponding conditions was sampled based on OrcaFlex. It was found that the cable tension was relatively high under low tide conditions.Meanwhile, abnormal operating conditions resulting from equipment damage were also studied. It was found that tensioner damage mainly manifested as tensile stress on the cable, while turntable damage mainly manifested as compressive stress. The reason for ultimate failure of the cable varied depending on cable location.
