发明名称 Device by ship for production/test production of oil/gas from a field below seabed level
摘要 To permit use of a ship as production ship, among other things in conjunction with a so-called STL-buoy (30) and in test production without a buoy (30), and in which the ship (10) is formed with a bottom recess (12) for the reception of the buoy (30) in a mutually pivotal manner, there has been formed, immediately above said bottom recess (12), a vertically oriented cavity (14) in the ship's hull. In this cavity (14) is pivotally supported a sleeve-shaped turret (16) which is configured with at least one through bore, channel or other passage for passing pipelines (24, 24'), pipeline portions (38, 38'), or the like, which may be connected at the one end via a swivel device (22) to one or more pipes or the like (26) fixed in the vessel. The sleeve-shaped turret (16) works alone during test production, but is connected to the buoy (30) so that together they form a turret (16, 30) in regular production.
