Abstract
A system and method for installing a fluid flow controller and telescoping spools beneath an offshore bottom supported drilling rig rotary table is disclosed. Upper and lower telescoping spools are provided for initially connecting a Diverter/BOP convertible fluid flow controller between structural casing in the well and a permanent housing beneath the drilling rig rotary table. A system and method for installing a fluid flow controller and a lower telescoping spool beneath and offshore bottom supported drilling rig rotary table is disclosed. This alternative embodiment of the invention provides the lower telescoping spool connected between the diverter/BOP convertible fluid flow controller and structural casing in the well. The top of the controller is connected to the permanent housing beneath the drilling rig rotary table. Additionally, a diverter system, a low pressure blowout preventer system and a high pressure blowout preventer system are disclosed for both embodiments.
