Analysis on the Inclination of Anchor Chain and Barrel in Mooring System

摘要

Anchor chain of mooring system can consist of several steel pipes. A series of stress analysis is used in this paper and the steel pipe mechanics model is established. According to the principle of virtual displacement and virtual work principle, the sum of gravity, buoyancy and tensile force is zero, because all the constraints which are given by the steel pipe are ideal constraints. Inclination can be calculated by the steel pipe in the sea wind speed of 12m/s and 24m/s in Table 1 and Table 2. Finally, according to the equilibrium equation, the inclination of the barrel at sea speed of 12m/s and 24m/s is 1.83° and 2.85° respectively.
