The invention discloses a polyester cable distributed mooring system used for medium-deep water and supported by collinear buoys, the polyester cable distributed mooring system is connected to a floating structure and a suction anchor, the polyester cable distributed mooring system comprises a plurality of mooring cable sets distributed in the circumferential direction of the floating structure, and each mooring cable set comprises a plurality of mooring cables; the mooring cable comprises an upper anchor chain, an upper polyester cable, a collinear buoy, a lower polyester cable and a lower anchor chain, one end of the upper anchor chain is hinged to the floating structure through an anchor gear, the other end of the upper anchor chain, the upper polyester cable, the collinear buoy, the lower polyester cable and the lower anchor chain are sequentially connected, and the lower anchor chain is connected to the suction anchor through a first connecting piece; the floating type mooring system is suitable for a sea area with high internal wave current, can provide permanent and reliable mooring limiting for a floating type structure used in the offshore petroleum and natural gas extraction process, is convenient to install and detach, is far smaller than a traditional mooring system in weight, is low in manufacturing and maintenance cost, and is beneficial to application and popularization of the mooring system on floating type production facilities.
本发明公开了一种用于中深水由共线浮筒支撑的聚酯缆分布式系泊系统,连接于浮式结构物和吸力锚,包括沿浮式结构物周向分布的多个系泊缆组,所述系泊缆组包括多根系泊缆,所述系泊缆包括上锚链、上聚酯缆、共线浮筒、下聚酯缆和下锚链,所述上锚链的一端通过锚机与浮式结构物铰接,所述上锚链的另一端、上聚酯缆、共线浮筒、下聚酯缆和下锚链依次连接,所述下锚链通过第一连接件连接于吸力锚;本发明适用于有较高内波流的海域,可以为海上石油天然气开采过程中使用的浮式结构物提供永久可靠系泊限位,且安装解脱方便,重量远小于传统系泊系统,制造维护成本低,有利于系泊系统在浮式生产设施上的应用与普及。
