    Description

    The Devin CCTLF delivers support for completion and post-completion deployment for coiled tubing and wireline operations aboard various offshore vessels. It provides a designated work window between the top drive and landing string for subsea completion and intervention activities. The system distributes weight evenly across the top section, down two legs, and back to center at the bottom section allowing for well-center rig up of coiled tubing, wireline, and slickline.

    Features/Benefits

    • Reducing downtime during operation whilst increasing safety 
    • Fully-automated tension adjustments eliminate downtime associated with tide adjustments 
    • Local display unit provides full access to system and real-time monitoring. 
    • Double hydraulic safety valves with recoil capability provides extensive safety towards loss of load, false opening, AHC failure, and blackship scenario. 
    • Hose rupture valves with extra redundancy 
    • System can continue compensation with both compensator hoses disconnected.
      Speeding up installation with radio remote operation of the following hydraulic actuated systems:
      • Engagement guiding/stabilizer system into guide rails with internal locking
      • Internal handling via both a main winch and a utility winch mounted on a swingarm
      • Adjustment of injector table up and down, in and out and rotation of the injector head
      • Bottom beam articulation to 90° and operation of elevator gate with internal locking

      Delivery also includes pressure vessel skid, fluid refill & filtration unit, handling frames, and control console including handheld radio remote.
