ABSTRACT:
A system is disclosed which may alternatively be used as a diverter or as a blowout preventer for a drilling rig. The system comprises a blowout preventer attached above a spool having a hydraulically driven sleeve/piston. An outlet flow passage in the spool, which may be connected to a vent line, is closed off by the sleeve wall when the spool piston is at rest.
Hydraulic ports are connected above and below the blowout preventer annular piston and above and below the spool annular piston. The ports below the blowout preventer piston and above the spool piston are in fluid communication with each other. A hydraulic circuit is provided having two valves between a source of pressurized hydraulic fluid and a drain.
