Abstract

An apparatus for transferring hydrocarbons from a subsea source to a vessel (1), wherein the risers (2) are suspended from a rotating body (8) and communicate with a swivel unit (3) comprising a number of swivel rings (5) having outlets (6) connected to a pipe system (7) on the vessel. The apparatus comprises a block (25) arranged between the risers (2) and the swivel unit (3) and provided with interior ducts (28) for connection of the risers (2) with respective swivel rings (5), and means (29) for selective closing of the ducts (28) are arranged between the risers (2) and the swivel unit (3). These means are integrated in the block (25). In an advantageous embodiment the block (25) is also provided with means (33) for selective interconnection of two or more of the ducts (28) in the block.

Description

technical field [0001] The present invention relates to apparatus for transferring hydrocarbons from a subsea source to a platform in which risers are suspended from a rotor and communicate with a rotating member comprising rotating rings having connecting At the outlet of the piping system on the platform, said equipment consists of a block, which is arranged between the riser and the rotating part, and is provided with internal pipes for connecting the riser with each rotating ring, for selective The means for shutting off the pipeline is arranged between the standpipe and the rotating part. Background technique [0002] In the offshore production of hydrocarbons (oil or gas), floating production platforms are often used today. The platform is held in position above the oil or gas field by means of appropriate anchoring devices, and the oil and / or gas (product) is fed into the platform by means of a main pipe extending upward from the seabed to a rotating body (turret) on...
