Causes of the Marine cable fault line accident? What are those?
At present, the ship berthing cable force monitoring relies mainly on the sailor on duty periodic inspections, and only by its sensory and experience to judge the cable stress to prevent the broken cable, because prevention effect by professional experience, physical strength and sense of responsibility is greatly restricted factors, such as it has a great deal of uncertainty, such as: different personnel to grasp different stress multiple rope is uniform;
Different duty personnel on duty for berthing Marine cable force monitoring the importance of different;
Different duty personnel on duty for berthing frequency different cable adjustment, etc.
Thus overcome the ship mooring attendant for Marine cable force monitoring of subjectivity and empirical problems, become accident prevention is broken cable urgent problems needed to resolve.
Analysis of causes of the Marine cable fault line accident in the following aspects: 1)
Marine cable and side friction, inevitable friction makes Marine rope broken wires, and the decrease of strength of Marine cable;
Multiple Marine cable uneven, make external forces are borne by part of the Marine cable and beyond the allowable strength;
Is developing toward the large ship, but also in development, to the direction of deep water berths to Marine cable required to bear the external force increased, at the same time different docking port, berth of the hydrological and meteorological conditions change multiterminal, Marine cable force changes in real time, while on duty personnel is difficult to find and take effective measures in time;
Marine cargo and port tide influence, has led to ship the float state of structure of random changes, lead to Marine cable force is random changes, and Marine cable and the ship's rail and the friction of bollard.
