Kittiwake A's steel jacket supports production and processing facilities configured for multiphase separation, gas compression and water handling. While original drilling facilities have been removed, the platform continues to receive hydrocarbons from subsea tie-backs. Fluids are processed through stabilisation and separation trains; oil is metered and exported via the Greater Kittiwake Area export pipeline to the Forties Pipeline System through the Unity platform, and processed gas is utilised for fuel/gas lift with surplus exported via a small diameter line to the SEGAL gas pipeline. Produced water treatment facilities handle effluent per regulatory standards. Utilities include onboard power generation, HVAC, firewater and safety systems, and control rooms coordinating operations and export interfaces. Accommodation supports personnel, and control and safety systems ensure stable long-term operation of multiple field tie-backs into the hub facility.
