<p>Gaseous and liquid effluents of an underwater well are separated efficiently and such that a slug flow regime is inhibited by: - providing a riser (4) or other underwater flowline with an upper portion (4B) for lifting substantially gaseous components (15) to a gas processing or receiving facility(6) above the water surface (7); - providing a gas-liquid separator (5) comprising an annular liquid collecting chamber (8) which co-axially surrounds a tubular lower portion (4A) of the riser having an at least partially permeable wall (4Al), which annular liquid collecting chamber (8) has an inclined orientation and is configured to allow liquid components that pass through the permeable wall to drain to a lower section of the chamber (9); - connecting a liquid transportation conduit (10) to the lower section (9A) of the liquid collecting chamber (8), which conduit (10) is provided with a liquid pump assembly (11) that pumps substantially liquid components (12) from the liquid collecting chamber to a liquid processing facility above the water surface (7).</p> |
