The invention discloses a semi-submersible production platform polyester cable mooring and tensioning method, and relates to the technical field of offshore oil engineering. According to the polyester cable mooring tensioning method for the semi-submersible production platform, four sets of platform anchor gears are arranged at the four corners of the semi-submersible production platform, chain stoppers are arranged on the anchor gears, each set of platform anchor gears comprises at least four, and polyester cable mooring is connected with the semi-submersible platform through the anchor gears. The tensioning method comprises the following steps that S1, the workboat and the semi-submersible production platform complete transmission of polyester cable mooring, the platform anchor gear continues to recycle the anchor leg, after a certain length of the anchor leg is recycled, the chain stopper is locked, and when the anchor leg is recycled, the recycling length is determined when the tenth to twelfth chain rings of the platform chain pass through the chain stopper of the platform anchor gear. According to the invention, the polyester cable can be tensioned safely and efficiently by adopting the semi-submersible production platform and the windlass system, the residual deformation of the polyester cable in the service period is reduced, and the safety of the semi-submersible production platform is guaranteed.

    本发明公开了半潜式生产平台聚酯缆系泊张紧方法,涉及海洋石油工程技术领域。半潜式生产平台聚酯缆系泊张紧方法,半潜式生产平台四角设置有四组平台锚机,锚机上均设置有止链器,每组平台锚机设置有至少4个,聚酯缆系泊通过锚机与半潜式平台进行连接,其张紧方法包括以下步骤:S1:作业船与半潜式生产平台完成聚酯缆系泊的传递,平台锚机继续回收锚腿,回收一段长度后,止链器锁止,回收锚腿时,回收长度由平台链第10‑12个链环经过平台锚机的止链器确定。本发明可实现采用半潜式生产平台及锚机系统安全高效的进行聚酯缆的张紧,减少聚酯缆在服役期间的残余形变,保障了半潜式生产平台的安全。
