This Electrical Feedthrough System design provides a high-reliability circuit for transmitting electrical signals from downhole gauges through the wellhead and Subsea Tree to the Subsea Control Module (SCM) for topside monitoring. The system incorporates Teledyne DGO's high integrity glass-seal technology in three critical pressure barriers for maximum long-term reliability. The feedthrough system creates a permanent connection to the Subsea Control Module when the tree is installed onto the wellhead. In addition, a permanent rig-based DHG cable termination is completed to connect the control line to the feedthrough system. The DHG connector is available with a variety of sealing packages, including fully testable, dual metal-to-metal sealing of all downhole tubing hanger interfaces.
Designed for long-term reliability in the subsea and downhole environments containing aggressive production and packer fluids as well as sour well (H2S) conditions, 6 years of rigorous system, component, and material qualification tests have successfully been completed on the design, verifying its robust capability.
