摘要

A system adapted for alternative use as a diverter or a blowout preventer for a bottom supported rig and adapted for positioning beneath a rotary table of the drilling rig is disclosed. The system comprises a fluid flow controller and at least two bases adapted for being alternatively removably secured to the controller. When the first base is in combination with the fluid flow controller, the system may be used only as a diverter and when the second base is used in combination with the fluid flow controller the system may be used only as a blowout preventer. A method according to the invention includes steps for installing the system adapted for alternative connection as a diverter or a blowout preventer for a bottom supported drilling rig after structural casing has been set in a borehole.
