An IBOP is typically a ball valve or other type of valve that is connected in line with the drills string. It can be closed to isolate the kick inside the drill string. Because an IBOP and its associated actuator is connected in line with the drill string, it will rotate with the drill string during drilling operations. Typically, IBOP’s are pneumatically powered. The air source, typically a pressurized cylinder, is generally stationary. Thus, the challenge is to get the air power from the stationary source to the rotating IBOP actuator. It is noted that often drilling is stopped before the IBOP is actuated, but for safety reasons, the IBOP must be connected to an air supply at all times during drilling operations.
