摘要： A closed loop control system for a core drilling mechanism automatically controls the penetration rate, the weight on the drill bit, and the torque load applied to the drill string, and maintains all three at or below preselected maximum values. The closed loop control system incorporates a controller that receives sensed information and generates corresponding control signals to control the penetration rate and thus the weight on the drill bit and the torque load through a servo valve in a hydraulic drive circuit. One or more sensors are provided to sense the penetration rate of the drill bit, and are coupled with the controller. Similarly, sensors are provided to determine the weight on the drill bit and the torque load applied to the drill string.

摘要： An apparatus and method for maintaining electrical and hydraulic connections between a junction box (or junction boxes) located on or near an offshore platform's floor and a movable drilling rig structure are disclosed. The disclosed invention is a unique vertically folding service arm capable of moving in both the horizontal and vertical directions in order to provide enhanced range of movement. The increased range of movement provided by the vertically folding service arm of the present invention allows electrical and hydraulic supply lines to remain connected between a junction box (or boxes) located on or near the platform floor and the rig structure even as the rig structure moves back-and-forth on the platform between multiple well centers. The vertically folding service arm of the present invention can also be easily disconnected and 'folded' for transport without requiring the electrical and hydraulic supply lines to be disconnected from the drilling rig structure.
