Definitions
- the invention relates to techniques for storing and injecting utility fluids in subsea installations.
- an umbilical duct generally comprises both a wiring system for the power supply of the subsea installation, control hydraulic fluid flow conduits, chemical delivery ducts, and also communication, control and power supply cables for deepwater equipment.
- umbilical ducts are subject to the environmental constraints of the seabed, for example thermal stresses and pressure constraints, calling for regular monitoring.
- the umbilical ducts must also be connected to the installation, and require the presence of a platform or a ship on the surface to ensure the injection and reception of fluids.
- the storage on a ship of chemicals such as methanol, demulsifiers, biocides or products preventing corrosion or the formation of deposits in the ducts of the installation, presents a significant environmental risk.
- FR 2 776 274 A1 and DE 25 38 419 A1 propose submarine storage tanks comprising a deformable elastomer reservoir located at the bottom of the water, connected to an underwater installation on the one hand, and to a ship located on the surface using an umbilical on the other hand.
- Document US 2012/0085276 A1 also proposes an underwater storage tank with deformable walls located at the bottom of the water.
- these documents do not propose any method to dispense with a umbilical duct connected to the surface to convey utilitarian fluids to the underwater installation, and do not propose any solution allowing safe storage of these fluids at the bottom of the tank. water for an operating period of several months. No method for safe and controlled injection of these fluids is proposed. Therefore, a method is sought for the efficient and safe storage and injection of utility fluids, such as chemicals, into subsea installations from trays at the bottom of the water.
- utility fluids such as chemicals
- the present invention proposes a method for injecting fluid into an underwater installation, the method comprising:
- the fluid storage system comprising at least one rigid-walled storage tank containing a utility fluid; and injecting at least a portion of the utility fluid into the subsea installation;
- This method has the particular advantage of not requiring umbilical conduit and platform or ship surface to inject a utility fluid.
- This utility fluid is stored near the plant in a rigid-walled tank maintained at the bottom of the water for the duration of the fluid injection.
- the method is particularly advantageous for the operation of installations having many satellite fields, in which the lengths of umbilical ducts necessary for connecting the different wellheads can reach several tens of km, considerably increasing the operating costs.
- the method also maintains a fluid storage tank for a period of several months at the bottom of the water, the fluid storage system comprising rigid walled tanks, better resistant to seabed stresses and compatibility constraints. chemical with utilitarian fluids as elastomer bins.
- the invention may also include a plurality of fluid storage bins containing the same utility fluid.
- the use of at least two storage bins containing the same utility fluid, namely a first bin and a second bin, allows continuous operation of the installation. Indeed, by injecting the fluid utility of only one fluid storage tank at a time, when the utilitarian fluid of the first tank is exhausted, the additional tray can be a reserve of utility fluid ensuring the continuous injection of fluid in the installation while the first bin is refilled.
- the descent and the ascent of the storage system can advantageously be carried out by means of a crane or any other lifting device from a platform or a ship located on the surface.
- utility fluid can mean both a gas and a liquid, for example hydrocarbons or a chemical such as a demulsifier, a biocide, a corrosion inhibitor, a hydrate formation inhibitor, a deposit inhibitor or a hydraulic control fluid.
- the storage tank may comprise a movable piston partition separating the utility fluid from the marine environment, and the injection of the utility fluid may comprise a translation of the partition.
- the method which is the subject of the invention can have the advantage of being able to be carried out in a hydrostatic configuration. Indeed, when the moving partition is stopped, the pressure in the portion of the tray containing the utility fluid may be equal to the pressure prevailing in the marine environment. In this way, it is possible to manufacture a fluid storage tank comprising lighter rigid walls, not requiring resistance to pressure differences greater than a few thousand hPa.
- the storage system may comprise a pump connected to the storage tank by a first conduit and to said subsea installation by a second conduit, and the injection of the commercial fluid may comprise the operation of the pump.
- the use of a pump to cause the displacement of the moving partition of the storage tank can overcome a mechanical actuator exerting pressure on the movable partition of the fluid storage tank.
- the pump causes displacement of the movable partition and the circulation of the utility fluid by creating a pressure difference between the marine environment and the utility fluid.
- the use of a pump makes it possible to separate from the tank the element actuating the movement of the piston of the fluid storage tank.
- one module may include the pumps, while another module may include the fluid storage bins.
- the pumps have a longer operating life than the cycle of use of the fluid storage bins. They can remain at the bottom of the water for more than a year, while the fluid storage tanks are advantageously raised to the surface when all the utilitarian fluid they contain has been exhausted, for example after a few months .
- the use of pumps may call an additional glare of the implementation of the method.
- the storage system may comprise an accumulation tank connected to the pump and to the subsea installation, and may comprise at least one valve on a portion of the third conduit connecting the accumulation tank to the installation under -Marine.
- the injection of the utility fluid may include:
- the accumulation tank can serve as an intermediate reservoir, maintained at a slightly higher pressure, typically greater than one millibar to ten bars, at the pressure of the underwater installation, and whose contents can be injected into the underwater installation by means of precise control of the opening and closing of a valve.
- the injection of the utility fluid can take place over a period of between one month and one year before the surface rise of said portion of the storage system.
- More than a month is a significant advantage in terms of maintenance costs and replacement of used bins. Indeed, if the fluid storage system and the bins it contains are able to withstand the stresses on the bottom of the water, the intervention of a platform or a ship on the surface to go upstream. fluid storage bins or other system modules, can be done with less frequency.
- the injection of utility fluid can be carried out continuously at a rate of a few tens of liters per hour, for chemicals such as, for example, demulsifiers, corrosion inhibitors, inhibitors of hydrate formation, inhibitors of deposits. However, some other products may not be injected continuous, such as biocides that can be injected sporadically at, for example, about two hundred liters per hour, five hours per week.
- a system for measuring the utility fluid contained in the storage bin may be included.
- the volume of utility fluid present in the fluid storage tank which allows to anticipate a replacement or filling of the latter. It is also possible to ensure control of the amount of utility fluid injected into the subsea installation.
- the fluid storage system may comprise at least one supply pipe of the storage tank, and the method may furthermore comprise:
- the fluid storage system may comprise at least one refueling umbilical connected to the storage tank on the one hand, and a surface utility fluid reservoir on the other hand, the refueling umbilical carrying out a filling of the storage bin.
- This embodiment makes it possible to maintain permanent control over the quantity of utility fluid contained in the storage bin.
- a filling of the storage tank from the surface keeps the latter longer for the bottom of the water, and up to the surface only for maintenance operations.

- a final step is to go up to the surface of the storage system or a part thereof comprising at least the fluid storage tank.
- the fluid storage and injection system 1 comprises several modules 11.
- modules 11 may differ from that shown in FIG. 2, in particular with a view to bringing the pumps 5 closer to the fluid storage bins 21-24, or to adapt to the configuration of the seabed in the vicinity of the installation 100. It is also possible that a module 11 contains only one pump 5.
- An example of module 11 is shown in Figure 3, showing a storage tank 21 provided with a connecting member 70 to a conduit.
- the module 11 includes hooking means 14 to a lifting device. These hooking means 14 may for example be in the form of openings made in a metal frame, intended to receive a hook, a carabiner or other hooked system, for example the cable of a crane or a winch.
- the storage and injection system 1 comprises at least two fluid storage tanks for the same type of utility fluid 30, so as to be able to replace an empty storage tank without having to interrupt the injection of said fluid into the storage tank. 100 installation.

- the storage system 1 makes it possible to reduce the direct interaction with the elements of the subsea installation 100.
- the use of an intermediate duct 60 coupled to a collector 260 makes it possible to go up to the surface for maintenance a pump 5 defective without having to disconnect the second conduit 6 of the installation 100.
- a valve 9, for example a solenoid valve is placed on the third conduit 16.
- the pump 5 can initially fill the accumulation tank 8.
- This accumulation tank 8 is able to withstand a high external pressure, for example a pressure exceeding one hundred thousand hPa .
- the control of the flow of utility fluid 30 injected into the installation 100 can be carried out by controlling the opening of the valve 9.
- the injection of the utility fluid 30 is usually effected by actuating a pump 5, thereby creating a vacuum in the utility fluid 30 of the fluid storage tank 21-24 to which the pump 5 is connected.
- the injected utility fluid flow 30 is difficult to control and depends essentially on the power and operating mode of the pump 5.
- the addition accumulation tank 8 described above allows the injection of utility fluid 30 with a low flow rate.
- a first possibility is to raise the empty fluid storage tank 21-24 to the surface using a crane or other lifting device provided on a platform or a ship. To do this, the hooking means 14 are arranged on the four corners of a removable module of the system 1 as shown in Figures 2 and 3.
