The invention discloses a variable-length constant-tension mooring system and method for a floating type offshore structure, and the system comprises a variable-length constant-tension mooring theoretical normal form, i.e., when a floating body horizontally shifts from an initial balance position, the tension of a mooring cable in the mooring system is kept at a constant value, and the tension of the mooring cable in the mooring system is kept at a constant value; meanwhile, the physical length of the mooring rope between the floating body mooring point and the seabed anchor point is allowed to change along with the change of the horizontal deviation of the floating body; the invention discloses a shared single-anchor variable-length constant-tension mooring system and method. The shared single-anchor variable-length constant-tension mooring system comprises a self-installable shared concrete gravity anchor located on a seabed, a plurality of mooring cables/chains with constant tension and variable lengths and a plurality of corresponding constant-tension fair lead devices connected to a floating body. A multi-anchor variable-length constant-tension mooring system comprises a plurality of anchors symmetrically arranged on a seabed, a plurality of corresponding mooring cables/chains with constant tension and variable length and a corresponding constant-tension fair lead device connected to a floating body.
一种用于漂浮式海上结构物的变长度恒张力系泊系统及方法,包括:一种可变长度恒定张力系泊理论范式,即当一个浮体从初始平衡位置产生水平偏移时,其系泊系统中系泊缆的张力保持为一个恒定值,同时允许浮体系泊点与海床锚点之间的系泊缆的物理长度随着浮体水平偏移的变化而变化;一种共享单锚变长度恒张力系泊系统和方法,包括:一个位于海床上的可自安装的共享混凝土重力锚,多条具有恒定张力可变长度的系泊缆/链,多个相应的连接在浮体上的恒定张力导缆器装置;一种多锚变长度恒张力系泊系统,包括:多个对称布置于海床上的锚、多条相对应的具有恒定张力可变长度的系泊缆/链和相对应的连接在浮体上的恒定张力导缆器装置。
