摘要： A subsea compression system and method wherein a wellstream fluid is flowed through a flow line (12) from a reservoir (10) and into a separation vessel (16) for subsequent compression in a compressor (18; 18′, 18″) prior to export of gas. A recycle line (24; 24′, 24″) is fluidly connected at a first end to the compressed wellstream at the outlet side of the compressor (18; 18′, 18″) and at a second end to the wellstream at a location between the separation vessel (16) and the inlet side of the compressor (18; 18′, 18″), the recycle line being capable of controllably (32) feeding fluid due to surge back to the compressor inlet side and avoiding the need to feed the fluid into the separation vessel, because the re-circulated gas is dry both due to having been separated at seawater temperature, and then being heated during recirculation.

摘要： A device for separating and collecting liquid in gas from a reservoir, which is attached to processing equipment (14, 15) for gas, said gas being delivered to the processing equipment from the device via an inlet pipe (24) to the processing equipment and the collected liquid is removed periodically from the device via liquid outlet pipe (7). The device is formed of a liquid separator (1) and a liquid collector (2) which are two separate chambers, and which are connected to each other via a valve (3), and that for draining of the collected liquid, the liquid collector (2) is connected to an outlet pipe (19) from the processing equipment via an intermediate valve (6), draining taking place with the aid of compressed gas which via the intermediate valve (6) is supplied from the processing equipment, or alternatively from onshore or a platform, from a gas pipe or a well stream gas pipe on the seabed or the like.

摘要： An apparatus for preventing seawater from penetrating into a compressor module during lowering to or retrieval from a compression plant on the seabed, with optional discharge of residual production fluids, as for instance hydrocarbons, from the compressor module prior to retrieval, wherein the compressor module comprises an electric motor (1) and a compressor (2) which are respectively connected via at least one shaft (8) and are arranged in a common pressure shell (3), an inlet pipe (5) and an outlet pipe (6) to and from the compressor module which respectively are provided with an isolation valve (7, 7′). The compressor module is distinguished in that it includes at least one filling pipe (16) which has a shut-off valve (15), at least one drainage pipe (12) which has a shut-off valve (13), and which is located at a lower end of the compressor module, and at least one overflow pipe (14) which has a shut-off valve (17), and which is spaced apart from the at least one filling pipe (16), and that prior to lowering to or retrieval from the seabed, with optional discharge of residual production fluids prior to retrieval, the compressor module is filled with filling fluid via the at least one filling pipe (16) until overflow of filling fluid through the at least one overflow pipe (14). The present invention also relates to a method which correspondingly prevents such penetration of seawater into and discharge of residual production fluid from the compressor module.
