The invention discloses a deepwater polyester cable mooring pre-laying and tie-back method. The method comprises the following steps of lowering a bottom chain through an installation ship; connectingthe bottom chain with a polyester cable, and continuously lowering the bottom chain; connecting a top chain and the polyester cable, and continuously lowering the bottom chain; connecting the bottomchain with a pile foundation; making the installation ship travel so as to enable the polyester cable to be moored and lowered to a seabed; after a lifting ship is installed and connected with the topchain, heading for a semi-submersible platform, and lifting polyester cable mooring; and connecting a platform chain on the semi-submersible platform with the top chain, and then recovering the platform chain to finish tie-back of the polyester cable mooring. According to the deepwater polyester cable mooring pre-laying and tie-back method, a foundation is laid for an installation method for deepwater polyester cable mooring and application of deepwater polyester cable mooring.
本发明公开了一种深水聚酯缆系泊预铺设和回接方法。所述方法包括如下步骤:通过安装船舶下放底部链;将所述底部链与聚酯缆连接,继续下放所述底部链;连接顶部链和所述聚酯缆,继续下放所述底部链;将所述底部链与桩基础连接;所述安装船舶行驶以使所述聚酯缆系泊下放海底;安装提拉船舶与所述顶部链连接后,驶向半潜平台,实现对所述聚酯缆系泊的提拉;将所述半潜平台上的平台链与所述顶部链连接,然后回收平台链完成所述聚酯缆系泊的回接。本发明深水聚酯缆系泊预铺设和回接方法,为针对深水聚酯缆系泊的安装方法,为深水聚酯缆系泊的应用奠定了基础。
