Abstract
A connector has an upper end for connection into the upper part of a drill string. The connector has an outer member that slides over an inner member, the outer member and the inner member having a locked position and an unlocked position. A latch assembly in the connector places the inner member and the outer member in the unlocked position in response to hydraulic fluid pressure applied to the connector. A ball valve assembly has an upper portion for connection with a lower end of the connector and a lower portion for connection into a lower part of the drill string. A ball valve element actuator in the ball valve assembly rotates a ball valve element to the closed position in response to the upper portion of the ball valve assembly moving downward relative to the lower portion of the ball valve assembly.
