Embodiment Construction
[0044] The present invention will be further described below in conjunction with the accompanying drawings.
[0045] Such as figure 1 As shown, an ultra-deep water offshore oil and gas engineering development system mainly includes surface floating production device 15, riser support buoy 10, tension mooring device, upper flexible jumper 20, lower rigid riser 25, oil production equipment 5 and seabed Wellhead 28.
[0046] The oil recovery equipment 5 is installed on the riser support buoy 10 .
[0047] The riser support buoy 10 is located at H1 under the water surface 16 to avoid the turbulent flow area under the sea surface, so that the riser support buoy 10 is hardly affected by the wind, waves and currents near the sea surface, and maintains a good position. performance.
[0048] Such as Figure 1-2 As shown, the riser support buoy 10 adopts a combined structure of a central column structure 11 and three rectangular section cantilever buoys 12 connected to the edge of ...
