Safaniya is developed through numerous fixed drilling and wellhead platforms connected to offshore tie-in structures and gas-oil separation plants. Individual wells flow through field gathering lines to the separation centres rather than to one central host. At the offshore gas-oil separation plants, wellstream passes through two parallel horizontal first-stage separators. Separated crude is boosted and pumped through subsea trunklines to the onshore Safaniya GOSP-1 complex for further treatment and onward entry into Saudi Arabia’s crude-pipeline and terminal network. Associated gas from offshore GOSP-2, GOSP-3 and GOSP-4 is gathered to dedicated compressor platforms. The compressor installations raise its pressure for transfer through permanent pipelines to onshore GOSP-1 and the wider gas system. A documented offshore separation centre comprises three bridge-linked platforms: a process platform, a central utilities and control platform, and an accommodation and support platform. Its utilities include a 13.5-megawatt gas-fired turbogenerator and compressed-air equipment. Permanent field systems include production and test manifolds, shipping pumps, metering, oily-water collection, operational and emergency flare systems, firewater, microwave communications and remotely actuated emergency shutdown. Control rooms monitor separation, pumping and utility functions, while the bridge-linked complexes include living quarters, heliports and boat landings for routine access. Safaniya’s offshore platforms have no crude-storage or tanker-offloading function; both liquid and associated-gas export are pipeline-based. Crude reaching shore continues through onshore separation and Saudi pipeline infrastructure.
