[0001] The utility model relates to the technical field of offshore oil drilling and repairing wells, in particular to an independent connecting and unloading double-root system. Background Art

[0002] In order to further improve the efficiency of drilling and workover, off-line loading and unloading of stand pipes has become a development trend of drilling and workover rigs. The so-called off-line loading and unloading of stand pipes does not occupy the center line of the wellhead, and the stand pipes can be loaded and unloaded independently, so that the loading and unloading of stand pipes and the drilling operation can be carried out simultaneously, saving time. With the increasing number of offshore oil platforms without workover rigs, relocatable workover rigs with small module design have come into being.

[0003] Deficiencies of existing technology:
