The invention discloses an offshore suction pile high-altitude hooking method which comprises the following steps: S1, hoisting a suction pile to a deck of a workboat at a wharf, then avoiding equipment arranged on the top of the suction pile, laying a hoisting rigging connected with the top of the suction pile on the top surface of the suction pile, and temporarily fixing the hoisting rigging; the connecting end, away from the suction pile, of the hoisting rigging protrudes out of the edge of the suction pile; s2, a first traction rope penetrates through the connecting end of the hoisting rigging, so that the two ends of the first traction rope are perpendicular to the bottom of the suction pile; s3, after the workboat advances to the offshore installation site, one end of a first traction rope is connected with the hook head end of the lifting hook; and S4, the other end of the first traction rope is pulled down, the end, connected with the lifting hook, of the first traction rope is pulled to move upwards, and the lifting hook is driven to move upwards till the hook head end of the lifting hook penetrates into the connecting end of the lifting rigging. According to the offshore suction pile high-altitude hooking method, unmanned high-altitude hooking operation of the suction pile is achieved, and the risk that field operation personnel operate at the top of the suction pile is eliminated.
本发明公开了一种海上吸力桩高空挂钩方法,包括:S1、在码头,将吸力桩吊装至作业船的甲板上后,避开吸力桩顶部上布置的设备,将吸力桩顶部连接的吊装索具铺设在吸力桩顶面上并进行临时固定,将吊装索具远离吸力桩的连接端凸出吸力桩的边缘;S2、将第一牵引绳穿过吊装索具的连接端,使第一牵引绳的两端分别垂向吸力桩的底部;S3、在作业船行进至海上安装地点后,将第一牵引绳的一端与吊钩的钩头端部连接;S4、下拉第一牵引绳的另一端,拉动第一牵引绳连接吊钩的一端向上移动,带动吊钩向上移动直至吊钩的钩头端穿进吊装索具的连接端。本发明的海上吸力桩高空挂钩方法,实现吸力桩无人高空挂钩操作,消除现场作业人员在吸力桩顶部作业的风险。
