Hibernia’s concrete base contains two drilling shafts with 32 well slots each, providing 64 platform slots for production, water-injection and gas-injection wells. Two platform drilling rigs support directional, horizontal and extended-reach drilling, allowing reservoir targets several kilometres from the structure to be reached. The integrated topsides comprise major processing, wellhead, drilling-mud, utilities and accommodation modules. Well fluids pass through multistage separation to divide crude oil, gas and produced water. Stabilised crude is routed to storage cells inside the gravity base. Produced water is treated for discharge or reinjection, while treated seawater supports waterflooding. Associated gas is compressed; most is reinjected for conservation and pressure support, with part retained as platform fuel. Installed systems include test separation, oil and gas metering, chemical injection, flare and relief equipment, electrical generation and power management, heating and ventilation, drilling controls, process control, fire-and-gas detection, emergency shutdown and marine and accommodation services. The gravity-based structure has serrated outer walls designed to resist iceberg impact and carries substantial solid ballast. Its internal cells store approximately 1.3 million barrels of crude. Oil export is independent of any shore pipeline. Two subsea pipelines connect the platform to the Hibernia Offshore Loading System, which incorporates submerged loading buoys and flexible hoses. Ice-strengthened shuttle tankers recover a buoy, connect the loading hose and transfer crude, principally for delivery to the Newfoundland Transshipment Terminal at Whiffen Head before onward shipment.
