Ceiba production is gathered through six subsea manifolds or well clusters, each incorporating water-injection support. Subsea trees connect to the clusters and FPSO through flowlines, flexible risers and control umbilicals. Multiphase booster pumps and gas lift assist flow from the seabed system, while treated injection water is pumped from the vessel back to the well clusters. When Sendje Ceiba replaced the temporary FPSO, the immediate hookup programme covered five existing producers plus three completed producers and two completed water injectors, with the subsea system designed for continued expansion. Its topsides contain an oil-and-gas process plant and dedicated water-injection facilities; processed liquids are conditioned for storage in the hull. The FPSO also serves as the export terminal for the Okume Complex: oil processed at the Elon central production facility travels approximately 25 kilometres through a 12-inch pipeline to Sendje Ceiba for storage and tanker lifting. Converted from the 275,000-deadweight-tonne Berge Hus, the vessel is approximately 350 metres long and 52 metres wide and has about two million barrels of crude-storage capacity. Installed electrical and control systems include topsides process control and shutdown, ship automation, emergency shutdown, fire-and-gas detection, high- and low-voltage distribution, motor-control centres, power management, a new generator and medium-voltage soft starting. Marine and process operations are coordinated from the vessel while permanent moorings retain it on station. Stabilised crude is periodically transferred from the cargo tanks to export tankers.
