The invention relates to the field of offshore anchor cable hanging, and provides a large floating structure abnormal anchor cable withdrawing construction method, which comprises the following steps: changing the related anchor cable force through a continuous jack to adjust the posture and angle of a large floating structure, connecting with an abnormal anchor cable through a first traction cable, temporarily locking the abnormal anchor cable, and then connecting with the large floating structure through a second traction cable. And the pin shaft for connecting the continuous jack steel strand connector with the closed cable joint connector of the abnormal anchor cable is removed, then the second traction cable is connected with the closed cable joint connector, the first traction cable and the second traction cable are made to slowly lower the closed cable joint connector to the anchor boat, and finally anchor withdrawing is achieved through cooperation of the two winches on the top of the steel open caisson.
本发明涉及海上锚缆挂设领域,提供了一种大型浮式结构异常锚缆退锚施工方法,本发明通过连续千斤顶改变相关锚缆缆力调整大型浮式结构姿态及角度,再通过第一牵引缆与异常锚缆相连接,以及对异常锚缆的临时锁定后,解除连接连续千斤顶钢绞线接头与异常锚缆的闭式索节接头的销轴,再利用第二牵引缆与闭式索节接头相连接,使第一、第二牵引缆缓慢下放闭式索节接头直至锚艇上,最后利用钢沉井顶部两台卷扬机配合实现退锚。
