Title: INTELLIGENT DRILLING RISER
Abstract:
A drilling riser system for connecting a drilling rig with a wellhead located at the sea floor is disclosed. The system includes a plurality of elongated riser sections connected end to end and an electrical transmission line extending along the plurality of riser sections, the electrical transmission line including a plurality of electrically conductive segments inductively coupled to one another. The system may further optionally include a sensor package (e.g., including at least one of an accelerometer, an inclinometer, a rotation sensor, and a strain gauge) deployed on at least one of the riser sections such that the transmission line provides electronic communication between the drilling rig and the sensor package
