Dan D contains multiple production well slots drilled into the reservoir and functions primarily as a wellhead support platform. Well fluids are routed via bridges and connection pipelines to Dan B for processing, where three-phase separation, gas conditioning and stabilization occur. Utility systems on Dan D include instrumentation and control for well operations, basic electrical distribution for safety and communication systems, emergency shutdown capability, and remote telemetry to Dan B and Dan FC. Export routes established through the Dan complex extend to the Gorm E riser platform for oil and to the Tyra hub for gas, with subsea ties and flowlines linking Dan D into the integrated infrastructure. Fire and gas detection systems and safety interlocks are installed to protect personnel and equipment, reflecting robust North Sea design standards.
