摘要： A coiled tubing deployment system includes an offshore rig having a reel positioned thereon and coiled tubing wound on the reel. A guide arch receives the coiled tubing from the reel and a monitoring support guide fixed to the offshore rig receives and directs the coiled tubing into water. The monitoring support guide has a frame and at least two hydraulic rams. A depth counter measures the coiled tubing deployed from the reel and generates length measurement signals, and sensors coupled to the at least two hydraulic rams measure real-time lateral movement of the coiled tubing with respect to the monitoring support guide as the coiled tubing is deployed into the water and thereby generate sensor signals. A data acquisition system receives and processes the length measurement and sensor signals to provide an output signal indicative of real-time bending fatigue of the coiled tubing at select locations along the coiled tubing.

摘要： Methods for real-time coiled tubing fatigue monitoring can establish a remaining operational life of a coiled tubing strand. Standard or low-cycle plastic fatigue in bending is measured each time the coiled tubing strand is deployed through a guide arch. Also, smaller, but higher frequency loads, e.g., high cycle loads imparted to the coiled tubing strand due to interaction with an oceanic environment, are also measured. A plurality of weight detectors may be coupled to a support frame below the guide for monitoring the high-cycle loads. The remaining operational life of the coiled tubing strand may be calculated based on both the plastic strains using a low-cycle fatigue analysis and the elastic strains using a high-cycle fatigue analysis. An operator may retire a coiled tubing strand prior to failure based on the calculated remaining operational life.

摘要： A bend stiffener is operable to be installed on site in a collapsed state and expanded upon installation to provide increased coverage of a tubing string to be reinforced by the bend stiffener. The bend stiffener is expandable upon the tripping of tubing through the bend stiffener. The bend stiffener includes a flexible sleeve having an outer flange at an upper end and sized to receive the tubing. The bend stiffener also includes an intermediary sleeve and an external sleeve. The intermediary sleeve has a cylindrical body and an internal flange for engaging and supporting the outer flange of the flexible sleeve. Similarly, the external sleeve has an internal flange for supporting an external flange of the intermediary sleeve. When installed, the flexible sleeve slides from the intermediary sleeve and the intermediary sleeve slides from the external sleeve so that each sleeve encloses and reinforces a segment of tubing.

摘要： Systems, methods, and apparatuses for adjusting and repositioning a coiled tubing tensioning device while deployed. The system comprises a tubing guide for receiving a coiled tubing, a tensioning device for maintaining the coiled tubing in tension, and a tower frame having a moveable platform supporting the weight of the tensioning device. The moveable platform is adjustable vertically to raise and lower the tensioning device with respect to the tower frame, and the tower frame permits the tensioning device to move horizontally with respect to a fixed ground point.
