Problems solved by technology

[0002] There are many offshore oil production platforms, especially CNOOC Shengli Chengdao Oilfield, Dagang Liaohe Offshore Oilfield, etc., with a total output of hundreds of millions of tons. So many oil production platforms continue to produce oil from the seabed every day, but oil wells are constantly clogged by wax and sediment , wellhead oil rod wear and other faults, causing the oil production platform to stop production, which requires the workover operation platform to dock with it through a tugboat for maintenance of the oil production wellhead; the offshore environment is harsh, and many workover operation platforms are in the process of docking with the oil production platform , Due to factors such as the operation error of the auxiliary tugboat and the action of wind and waves, the impact loss of the oil production platform is caused, and even the overturning, so a reliable device is needed to solve this problem
