发明名称 Compensation system for a jacking frame
摘要 An offshore oil well platform assembly is provided that includes a jacking frame, which supports a coiled tubing injector, which in turn is connected to a wellhead during a coiled tubing operation; and a compensation system. The compensation system includes a force measurement system which measures forces applied to the wellhead; a force delivery system, which provides a compensating force to counteract at least a portion of the measured forces on the wellhead; and a control system which receives signals from the force measurement system indicative of the measured forces, and operates the force delivery system based on the measured forces.
