Anasuria FPSO
Anasuria is a floating production, storage and offloading vessel serving the Guillemot and Teal oil fields in the UK Central North Sea, Block 21/19. Installed in 1996, it processes and stores oil from multiple subsea developments. The FPSO is permanently moored and exports stabilized crude to shuttle tankers.

Field
The Guillemot and Teal fields lie in the Central North Sea and produce oil from Jurassic sandstone reservoirs. Discovered in the 1980s, the fields were developed using subsea wells tied back to a shared FPSO to optimize infrastructure and extend field life.
Facilities
The Anasuria FPSO receives production from subsea wells via flexible risers. Processing facilities include three-phase separation, oil stabilization, and produced water treatment. Stabilized crude is stored in hull tanks and exported to shuttle tankers in tandem configuration. Produced water is treated prior to discharge in accordance with environmental standards. Associated gas is used for onboard power generation, with surplus managed through controlled systems. Utilities include power generation, seawater lift, firewater and deluge systems, inert gas systems, chemical injection, and integrated control and safety systems. The FPSO is turret-moored, enabling weather-vaning and reducing mooring loads. Anasuria serves as the long-term production hub for the Guillemot and Teal developments.
