ELECTRICAL FEEDTHROUGH SYSTEM FOR VERTICAL SUBSEA WELLHEAD COMPLETIONS - 1

ELECTRICAL PRODUCTS ELECTRICAL FEEDTHROUGH SYSTEM • Fully qualified ELECTRICAL FEEDTHROUGH SYSTEM FOR VERTICAL SUBSEA WELLHEAD COMPLETIONS • Highly reliable electrical connection for downhole gauges Teledyne DGO provides a qualified, highly synergistic pressure and temperature cycling. • Glass-to-metal sealing technology reliable Electrical Feedthrough System for Refer to the specifications for more detail or from downhole instrumentation through the wellhead. The system incorporates DGO’s glass-to-metal sealing technology in four • Glass-to-metal sealed pressure barriers (4 places) critical pressure barriers for maximum long • Underwater, wet mateable connections term reliability. It incorporates a wetmate • Rig testable interface seals connection between the tubing hanger and running tool, enabling continuous monitoring of instrumentation during run-in and initial production. A permanent connection to the Subsea Control Module is established through the wetmate interface when the tree is landed subsea. The system is designed for long-term reliability in containing aggressive production and packer fluids, artificial lift, as well as sour well (H2S) conditions. Rigorous system, component and material qualification tests have been successfully completed on the design, verifying its robust capability. This testing included • Modular design to suit varying installation envelopes • Standard Ø1/4” (6.35mm) DHG control line interface - Simple, quick, testable DHG connector rig terminations • Dual-barrier philosophy throughout: - Primary metal seals - Secondary elastomer seals - Redundant sealing • API 6A, 16D & 17D compliant - HH material class (Sour Service) - Exceeds U temperature class - Product specification level 3 – PSL 3 - Performance requirement level 2 – PR2 • NACE MR0175 compliant metallic elements
