Abstract

Mooring system consists of pipes, steel drum, heavy ball, welding chain and a special anti-drag anchor. Due to its ability to tie up the buoy system, the buoy system can work properly under the influence of wind loads. When the mooring system is working normally, the angel of the sea floor and the tangential direction of the connection of anchor chain and anchor cannot exceed 16 degrees. And the inclination angle of steel drum cannot exceed 5 degrees. To solve the parameters of the mooring system, each part in the system needs to be analyzed individually. Suppose the angel of the sea floor and the tangential direction of the connection of anchor chain and anchor is exactly 0°, in this case the draught height of the buoy can be calculated. Now the tension of the steel pipe for the buoy can be solved by static equilibrium equation. Through static equilibrium equation and torque balance equation, the tension of steel pipes and steel drum can also be analyzed. After the tension and inclination of every section are analyzed, the suspension length of the anchor chain can be gained by using catenary equation. Assume it as a new volume, then repeat the above process step by step. Finally, through Iterative Approximation, the true value of the height of draught can be calculated. Using this value, the inclination angle of steel pipes and steel drum can be calculated, so that we can analyze whether the mooring system can work normally with certain wind speed.
