Patent number: 10859084Abstract: A subsea water injection pump includes components that are cooled and lubricated by the process fluid. The pump includes opposing stages of impellers in a “back-to-back” arrangement such that the axial forces of the impeller stages partially or nearly fully offset each other. In some cases, a combination of barrier fluid and process fluid is used for lubrication and cooling.Type: GrantFiled: April 26, 2016Date of Patent: December 8, 2020Assignee: ONESUBSEA IP UK LIMITEDInventors: Åsmund Valland, Helge Dale

Publication number: 20180119737Abstract: In rotating machine having a vertically oriented rotating shaft, a static magnetic force is used to simulate rotor weight and create the desired bearing preload. By installing a magnet the gravity based preload on the shaft journal bearings of a horizontal machine can be simulated for a vertical shaft. This can increase rotor stability, reduce the machine's vulnerability to hydraulically induced imbalance forces and give a more smooth transition through various shaft speeds.Type: ApplicationFiled: October 27, 2017Publication date: May 3, 2018Inventors: Hans Fredrik Kjellnes, Erik A. Torbergsen, Åsmund Valland, Audun Magne Askeland

Publication number: 20160341281Abstract: According to some embodiments, a subsea fluid processing system is described that includes a subsea electric motor that rotates a motor shaft about a central axis. A subsea fluid processing machine driven by a second shaft being rotated about the central axis. A subsea gear train system includes a plurality of gears positioned in one or more at least partially or fully oil-filled volumes. The plurality of gears are configured and arranged to transmit power from the first shaft to the second shaft wherein one revolution of the first shaft causes greater than one revolution of the second shaft. In some examples the gear form an epicyclic gear train arrangement.Type: ApplicationFiled: May 18, 2015Publication date: November 24, 2016Inventors: Anders Brunvold, Hans Fredrik Kjellnes, Asmund Valland

Patent number: 9303491Abstract: There is disclosed a subsea cooler for the cooling of a fluid flowing in a subsea flow line. The subsea cooler comprises an inlet and an outlet which are connectable to the subsea flow line and at least two cooling sections arranged in fluid communication with the inlet and the outlet of the subsea cooler. Each cooling section includes a plurality of cooling pipes which are configured such that they exchange heat energy with the surrounding sea water when the subsea cooler is in use. The subsea cooler is further provided with valve means such that the flow of fluid through the cooling sections may be regulated individually.Type: GrantFiled: March 29, 2010Date of Patent: April 5, 2016Assignee: Framo Engineering ASInventors: Stig Kare Kanstad, Nils-Egil Kangas, Asmund Valland, Atle Berle

Patent number: 9163482Abstract: There is provided a subsea system for increasing pressure and/or flow rate in a flow line, the subsea system being arranged in fluid communication with said flow line which receives fluid from at least one fluid source. The subsea system comprises at least one compressor or pump and at least one subsea cooler which is arranged in the flow line in series with the at least one compressor. The subsea system further comprises a recirculation line which is configured such that at least a portion of the fluid flowing in the flow line downstream the at least one compressor and the at least one subsea cooler may be recirculated back to the flow line upstream the at least one compressor and the at least one subsea cooler such that the recirculating line can be used for capacity regulation of the at least one compressor and cleaning of the at least one subsea cooler.Type: GrantFiled: March 29, 2010Date of Patent: October 20, 2015Assignee: Framo Engineering ASInventors: Stig Kare Kanstad, Asmund Valland, Nils-Egil Kangas, Atle Berle
