Definitions
- the inventions relate to a system and method for delivering fluid under pressure for use subsea.
- Subsea devices often require fluids, e.g. hydraulic fluids or chemicals for injection and the like. These fluids are typically delivered to the device under pressure. As subsea devices are deployed deeper and deeper, the pressures required have increased.
- umbilicals from the surface currently need to contain a plurality of fluid conduits which increases cost and complexity.
- FIG. 1 is a planar view in of an exemplary system
- FIG. 2 is a cross-sectional view of an exemplary conduit
- FIG. 3 is a planar view of a second exemplary system
- FIG. 4 is a flowchart of an exemplary method. DETAILED DESCRIPTION OF
- system 1 is adapted to provide fluid under pressure to a subsea device, e.g. a device adapted for use in an installation workover control system.
- system 1 comprises fluid source 10 located distally from seabed 100 and adapted to provide fluid 5 suitable for use with the subsea device, e.g.
- fluid pressurizer 20 in fluid communication with fluid source 10, fluid pressurizer 20 adapted to pressurize fluid 5 to a first pressure; fluid pressure intensifier 30 adapted to be located subsea, fluid pressure intensifier 30 further adapted to receive fluid 5 at a first fluid pressure and output fluid 5 at a fluid pressure higher than the first fluid pressure; and fluid conduit 40 in fluid communication with fluid pressurizer 20 and fluid pressure intensifier 30.
- Fluid source 10 may be located on vessel 2 but does not have to be. In a preferred embodiment, fluid source 10 is located distally from seabed 100 such as near or at the water surface. Fluid 5 may be a control fluid, a tree chemical fluid, or the like, or a combination thereof.
- Fluid pressurizer 20 is adapted to provide a pressure substantially lower than the delivery pressure required for injection of fluid 5 to subsea device 110. Fluid pressurizer 20 may be located proximate the surface or subsea distally from fluid pressure intensifier 30 and may be part of fluid source 10, i.e. integrated with fluid source 10, or otherwise in fluid communication with fluid source 10 such as via fluid conduit 11.
- Fluid pressurizer 20 is in fluid communication with fluid pressure intensifier 30, which is located proximate seabed 100, such as via fluid conduit 40.
- fluid pressure intensifier 30 may be located on seabed 100 or near seabed 110 such as on an ROV (not shown in the figures).
- Fluid pressurizer intensifier 30 is adapted to provide fluid 5 to one or more subsea devices, e.g. subsea device 110, at higher fluid pressure than fluid pressurizer 20 provides.
- fluid pressure intensifier 30 is adapted to provide a pressure substantially higher than 10,000 PSI and, more preferably, in the range of around 15,000 to around 20,000 psi.
- fluid pressure intensifier 30 comprises a plurality of fluid, pressure intensifiers 30 connected in series, parallel, or a combination thereof.
- One or more fluid pressure intensifiers 30 may utilize proportional hydraulic valves.
- fluid conduit 40 is an umbilical which may further comprise one or more fluid conduits 42, electrical power conduits 43, data conduits 44, or a coinbination thereof.
- System 1 may further comprise surface control panel 4 operatively in communication with fluid pressurizer 20, fluid pressure intensifier 30, or both.
- system 1 is adapted to provide an installation workover control system and comprises fluid source 10 located distally from seabed 100 and adapted to provide fluid 5 suitable for use with a subsea installation workover function; fluid pressurizer 20 in fluid communication with fluid source 10, fluid pressurizer 20 adapted to pressurize fluid 5 to a first pressure; fluid pressure intensifier 30 located at a surface location, fluid pressure intensifier 30 further adapted to receive fluid 5 at a first fluid pressure and output fluid 5 at a fluid pressure higher than the first fluid pressure; and fluid conduit 40 in fluid communication with fluid pressurizer 20 and fluid pressure intensifier 30.
- Fluid pressure intensifier 30 may be further adapted to be driven hydraulically from the surface.
- fluid under pressure may be provided for subsea use such as with a subsea installation workover control system by pumping fluid 5 at a first fluid pressure from a first location to fluid pressure intensifier 20 located subsea; increasing the fluid pressure to a higher pressure at the subsea fluid pressure intensifier 20; and providing the increased pressure fluid 5 for use subsea.
- fluid 5 is pumped at a first fluid pressure from a pump located at a surface location or a pump located subsea, e.g. fluid pressurizer 20, but not located proximate fluid pressure intensifier 30.
- a pump located at a surface location or a pump located subsea e.g. fluid pressurizer 20, but not located proximate fluid pressure intensifier 30.
