摘要
(US10633961) A subsea oil filtration system is described that forms a closed circuit with and is mounted on or connected to a subsea rotating machine. According to some embodiments, the oil filtration system enables the removal of dirt and/or water that has entered the barrier fluid/oil system whether it comes from the Hydraulic Pressure Unit (HPU), from the umbilical or from other parts of the oil contained lubrication and/or barrier fluid systems.

(US10633961) What is claimed is: 1. A subsea system for processing a process fluid comprising:   an electric motor filled with a barrier fluid that provides lubrication and a barrier between portions of the electric motor and surrounding seawater;   a rotating fluid processor driven by said electric motor and lubricated by said barrier fluid; and   a subsea barrier fluid filtration system comprising one or more separation components configured to separate contaminants, including water, from said barrier fluid by circulating a portion of the barrier fluid through the one or more separation components, and wherein the one or more separation components comprises a water coalescer comprising a coalescer media configured to mechanically coalesce water droplets in the barrier fluid and to allow the water droplets to pass through the coalescer media. 2. The system according to claim 1 wherein the contaminants include particles in the barrier fluid. 3. The system according to claim 2 wherein the particles are separated by flowing at least a portion of the barrier fluid through a primary particle filtration medium. 4. The system according to claim 3 wherein said filtration system further comprises one or more bypass conduits configured to allow at least a portion of the barrier fluid to bypass the primary filtration medium. 5. The system according to claim 4 wherein said filtration system further comprises a secondary separation unit configured to provide contaminant separation in cases when said primary filtration medium is partially or completely clogged. 6. The system according to claim 5 wherein said secondary separation unit is configured to separate the contaminants by allowing for gravity collection of condensed water. 7. The system according to claim 5 wherein said secondary separation unit is configured to separate particle contaminants by gravity separation of the particle contaminants. 8. The system according to claim 4 wherein said filtration system is configured to allow greater than 2% of fluid flowing through the filtration system to flow though said one or more bypass conduits even when said primary filtration medium is clean. 9. The system according to claim 4 wherein said filtration system further comprises:   a secondary particle filtration medium downstream of the primary filtration medium; and   a second bypass conduit configured to allow at least a portion of the barrier fluid to bypass the secondary filtration medium. 10. The system according to claim 1 wherein the one or more separation components further comprises a water filter unit that includes a water separation membrane configured to block coalesced water droplets from passing through the membrane. 11. The system according to claim 1 wherein the filtration system further comprises a water collection volume configured to store water separated from the barrier fluid. 12. The system according to claim 1 wherein said one or more separation components comprises a magnetic separation unit configured to extract at least magnetically susceptible material from the barrier fluid. 13. The system according to claim 1 wherein the rotating fluid processor is a subsea pump. 14. The system according to claim 1 wherein the rotating fluid processor is a subsea compressor. 15. The system according to claim 1 further comprising a barrier fluid cooling system configured to cool at least a portion of the barrier fluid, said cooling system and said filtration system configured in parallel with each other. 16. A subsea system for processing a process fluid comprising:   an electric motor filled with a barrier fluid that provides lubrication and a barrier between portions of the electric motor and surrounding seawater;   a rotating fluid processor driven by said electric motor and lubricated by said barrier fluid; and   a subsea barrier fluid filtration system comprising one or more separation components configured to separate contaminants, including water, from said barrier fluid by circulating a portion of the barrier fluid through the one or more separation components, and wherein the one or more separation components comprises a water filter unit that includes a water separation membrane configured to block water droplets from passing through the membrane;   wherein the one or more separation components comprises a water coalescer comprising a coalescer media that is entirely spaced from and positioned upstream of the water separation membrane, the coalescer media being configured to mechanically coalesce the water droplets in the barrier fluid. 17. The system according to claim 16, wherein the filtration system further comprises a water collection volume configured to store water separated from the barrier fluid. 18. The system according to claim 16, wherein the contaminants include particles in the barrier fluid and the particles are separated by flowing at least a portion of the barrier fluid through a primary particle filtration medium. 19. The system according to claim 18, wherein said filtration system further comprises one or more bypass conduits configured to allow at least a portion of the barrier fluid to bypass the primary filtration medium. 20. The system according to claim 19, wherein said filtration system further comprises a secondary separation unit configured to provide contaminant separation in cases when said primary filtration medium is partially or completely clogged. 21. A subsea system for processing a process fluid comprising:   an electric motor filled with a barrier fluid that provides lubrication and a barrier between portions of the electric motor and surrounding seawater;   a rotating fluid processor driven by said electric motor and lubricated by said barrier fluid; and   a subsea barrier fluid filtration system comprising one or more separation components configured to separate contaminants, including water, from said barrier fluid by circulating a portion of the barrier fluid through the one or more separation components, wherein the filtration system further comprises a water collection volume configured to store water separated from the barrier fluid;   wherein the one or more separation components comprises:    a water coalescer comprising an annular coalescer media centrally positioned in a casing having a central axis and configured to mechanically coalesce water droplets in the barrier fluid and to allow the water droplets to pass through the coalescer media; and    a water filter unit comprising an annular water separator membrane centrally positioned in the casing and entirely spaced from the coalescer media along the central axis of the casing, wherein the water separator membrane is configured to block the water droplets from passing through the membrane;   wherein the water collection volume comprises an annular chamber defined by an inner surface of the casing and is configured to receive the water droplets from the water filter unit. 22. The system according to claim 21, wherein the water filter unit is configured to block coalesced water droplets from passing through the membrane. 23. The system according to claim 21, wherein said one or more separation components comprises a magnetic separation unit configured to extract at least magnetically susceptible material from the barrier fluid. 24. The system according to claim 21, wherein the contaminants include particles in the barrier fluid and the particles are separated by flowing at least a portion of the barrier fluid through a primary particle filtration medium. 25. The system according to claim 24, wherein said filtration system further comprises one or more bypass conduits configured to allow at least a portion of the barrier fluid to bypass the primary filtration medium.
