Embodiment Construction
[0016] Now combined with the manual figure 1 , the present invention is further described:
[0017] A deepwater underwater oil storage oil production device with dynamic positioning buoys. The whole system includes an underwater wellhead module 1, an underwater processing module 2, an oil-water replacement underwater oil storage module 3, a deepwater riser 4, and a dynamic positioning buoy 5 , shuttle tanker 6; the underwater wellhead module 1, the underwater processing module 2, and the oil-water replacement underwater oil storage module 3 are all located on the seabed and connected in series; The lower oil storage module 3 is connected, and the other end is connected with the dynamic positioning buoy 5; the shuttle tanker 6 is moored on the dynamic positioning buoy 5 when loading oil.
[0018] Considering the cost and technical problems, when the water depth is greater than 1500m, the current marine engineering field generally no longer uses lanyards to locate large floatin...
