  • Patent number: 11970924
    Abstract: A subsea system includes a first foundation structure supporting a first compressor train and having a connection interface for connecting to a second foundation structure supporting an additional compressor train. The first compressor train includes a first compressor having an inlet connectable via a fluid line to a well flow line. A compressed fluid line having a flow regulation device is connected to an outlet of the first compressor and to a common outlet for compressed fluid. A first connection line is connected to the compressed fluid line at a position upstream of the flow regulation device, and a third connection line is connected to the fluid line at a position upstream of the first compressor. Each of the first and third connection lines includes a flow regulating device and is configured to connect to the additional compressor train.

  • Patent number: 11542794
    Abstract: A subsea hydrocarbon flow compression system (100) for receiving a hydrocarbon stream from at least one upstream flowline (102, 104) and supplying the hydrocarbon stream to at least one downstream flowline (106, 108) at an increased pressure, wherein the compression system comprises first and second compressor trains (110a, 110b), wherein each compressor train comprises an inlet port (112a, 112b) which is connectable to the at least one upstream flowline (102, 104); an outlet port (114a, 114b) which is connectable to the at least one downstream flowline (106, 108); a conditioning unit (116a, 116b) which is connected to the inlet port via a first flowline (118a, 118b); and a first flow path for the hydrocarbon fluid comprising a compressor (120a, 120b), which compressor is connected to the conditioning unit via a second flowline (122a, 122b) and to the outlet port via a third flowline (124a, 124b), wherein a controllable first valve (126) is arranged in the third flowline of the first compressor train for cont

  • Patent number: 8950979
    Abstract: The present invention regards a method for laying pipelines on the seabed comprising the steps of attaching an end (2) of the pipeline (1) to a structure (10, 20), lowering the structure with the pipeline to the seabed, allowing the pipeline end to pivot relative the structure, measuring the inclination of the pipeline end relative to the seabed, modifying a pipe spool such that one end is given the same inclination of the end as the pipeline and that at least one part of the pipe spool will be resting on the seabed after connection, connecting the pipe spool to the pipeline. The invention also regards a pipeline installation device where at least a one side of a top structure is allowed to move relative a foundation structure.
