According to the tool and method for disassembling and assembling the underwater propeller of the marine drilling platform on the sea, the propeller is hung through a sling special for a bollard hanging point, the occupancy rate of a floating crane is reduced, the operation time of the floating crane is shortened, the renting cost of the floating crane is reduced, and the efficiency and safety of underwater operation of divers can be improved. The newly-manufactured pipe cleaner is used for replacing a steel pipe to clean away the oyster and other organisms in the lifting pipe, the cleaning speed and efficiency are greatly improved, and the labor cost can be effectively reduced; the steel structure operation platform is manufactured and used, so that on-site frame building time and hoisting and transferring time are greatly shortened, and the protection level of a hydraulic lifting device pump station and diving equipment and the safety of personnel operation are improved; the hydraulic lifter supporting seat is manufactured and used, the risk that a lower caisson enters water and is repaired due to the fact that cracks are generated after a lifting pipe flange base is stressed is reduced, a lifter lower lifting appliance and a connecting lifting belt of the lifter lower lifting appliance are manufactured and used, and the underwater operation efficiency of a diver and the lifting operation safety are greatly improved.
本发明公开了一种在海上拆装海洋钻井平台水下推进器的工装及其方法,通过缆桩挂点专用吊带悬挂推进器,减少了浮吊的占用率,缩短了浮吊作业时间及租用成本,且有利于提高潜水员水下作业的效率和安全性;用新制的清管器取代钢管对提升管内的海蛎子等生物进行清理,大大提高了清理的速度和效率,能有效减少人工成本;制作及使用钢结构作业平台,大大缩短了现场搭架的时间和吊运转移时间,提高了液压提升装置泵站及潜水设备的防护等级和人员作业的安全;制作及使用液压提升器支撑座,减少了提升管法兰基座受力后产生裂纹使下部沉箱进水而返修的风险,制作及使用提升器下吊具及其连接吊带,大大提高潜水员水下作业的效率和提升作业的安全性。
