White Rose initially produced through the Central and Southern subsea drill centres, with the Northern Drill Centre developed for gas injection and underground storage. The North Amethyst Drill Centre was tied back to SeaRose and entered production in 2010; the South White Rose Extension drill centre followed in 2015. Subsea trees, manifolds and associated equipment are installed in excavated seabed glory holes that protect them from iceberg scour. Flexible production, water-injection, gas-service and control lines connect the drill centres to the FPSO. SeaRose topsides include a three-stage oil-stabilisation train, a three-stage gas-compression train, produced-water treatment and seawater-injection facilities. Separated gas is compressed for reservoir reinjection and vessel fuel rather than exported through a sales-gas pipeline. Stabilised crude is routed to hull cargo tanks providing approximately 940,000 barrels of storage. Export uses tandem offloading: an ice-strengthened shuttle tanker positions astern and receives crude through the FPSO’s flexible loading hose. The 258-metre vessel is held through a disconnectable internal turret carrying the production, injection and control risers. The turret can be released when severe iceberg or sea-ice conditions require the FPSO to leave the field. Thrusters support heading control and station keeping. Permanent utilities include onboard electrical generation, chemical injection, metering, seawater lift, flare and pressure relief, firewater, emergency shutdown, fire-and-gas detection, process and subsea control, marine systems and living quarters. SeaRose has no fixed bridge connection or crude-export pipeline.
