摘要

The system of floats to columns of riser in platforms and drilling vessels and submarine oil and gas production.Invention patent for a system of floats which is understood by the inflatable floats 7 are connected together and fed by the compressor 24 through the first float 7 more down and floats 7 when pressurized solidly united states joint riser column 3 where Are the floats 7 equipped with valves that allow communication between them in cascade.So that the outlet valve 14 of all the floats is set to open in the same differential pressure between the pressure of the environment and the pressure of the expansion chamber of the float 7 where it is placed.To be actuated to open the valve 14 of the float 7 more under gives way to the compressed air and force the valve opening 14 placed on the float 7 above and so on to the surface from which the air flow is maintained in flow and pressure necessary to leave a In the surface meaning equalization system, the floats are equipped with lugs (17, 18, 19.20 as a way to transfer the thrust for the joint of column of riser 3 if there is slippage of the float 7.
