Definitions
- the present invention relates to the field of floating structures for storing and/or transporting gas in the liquid state and more particularly concerns a system for managing gas stored and/or transported within such structures.
- a floating structure comprising a tank of gas in the liquid state intended to be consumed and/or delivered to a destination point
- said floating structure can use the gas having evaporated within of the tank, then compress it in order to power the motor(s) of the floating structure.
- a first disadvantage of these known technologies lies in the fact that they are not optimized from the point of view of overall system consumption. For example, oversized resources are implemented in a majority of use cases, which causes overconsumption. In such a case, the cooling of the gas cargo to the liquid state is excessive and thus leads to excess energy consumption.
- the present invention allows optimal gas management by proposing a system for managing a gas contained in at least one tank of a floating structure which comprises at least one gas consuming device, the management system comprising: at least one circuit gas supply of the gas consuming device, the supply circuit comprising at least one compression device comprising at least a first compression stage, a second compression stage and a third compression stage and configured to compress gas gas taken in the vapor state from the tank, the compression device delivering the gas in the vapor state at three different pressure levels, at least one heat treatment circuit for the gas in the vapor state compressed by at least the one of the compression stages of the compression device, at least one first heat exchanger configured to carry out a heat exchange between the gas in vapor state circulating in the supply circuit between the tank and the compression device and the gas in the vapor state circulating in the heat treatment circuit, at least one cooling circuit comprising at least one pump configured to take the gas in the liquid state from the tank, at least one second heat exchanger configured to carry out an exchange of heat between the gas in vapor state circulating in the heat
- the gas in the vapor state in particular the gas in the vapor state intended to be reliquefied, can be compressed at different pressure levels, each of these pressure levels being adapted to different situations in which the floating structure finds itself. From these different pressure levels, the gas in the vapor state is treated differently by circulating in the heat treatment circuit, particularly in terms of the heat exchanges occurring within the heat exchangers and the potential expansion of the gas. in vapor state.
- the invention thus makes it possible to exploit available cold resources without over-consuming to reliquefy the gas in the vapor state.
- the supply circuit makes it possible to take the gas in the vapor state which accumulates at the level of a tank head.
- This gas in vapor state comes from the evaporation of part of the cargo of gas in liquid state contained in the tank.
- the gas in the vapor state can therefore be consumed or reliquefied, but must generally be evacuated in order to regulate the pressure in the tank.
- the compression device therefore ensures the suction of gas in vapor state from the tank and compresses it.
- the compression device can for example be a plurality of compressors arranged in series with each other, or a single compressor with multiple compression stages.
- the first portion is thus associated with the first pressure level, that is to say when the compressed gas leaves the compression device between the first compression stage and the second compression stage.
- the second portion is associated with the second pressure level, that is to say when the compressed gas leaves the compression device between the second compression stage and the third compression stage.
- the gas compressed by the third compression stage is thus compressed by the entire compression device.
- the gas in the vapor state can then reach a pressure of between 250 and 400 bars.
- the gas in the vapor state compressed by the second compression stage reaches a pressure lower than the pressure delivered by the third compression stage, for example between 120 and 150 bars
- the gas in the vapor state compressed by the first stage compression reaches a pressure lower than the pressure delivered by the second compression stage, for example between 7 and 20 bars.
- the pressure of the gas in the vapor state is particularly important for supplying the gas consuming device because the latter can only consume the gas in the vapor state if it is at a compatible pressure.
- the gas in the vapor state If the gas in the vapor state is not compatible with the gas consuming device or if the gas consuming device does not require power, the gas in the vapor state then circulates in the treatment circuit thermal. If the gas consuming device only needs a fraction of the gas in vapor state for its own consumption, the rest of the gas in vapor state then also circulates in the heat treatment circuit. One of the functions of this heat treatment circuit is to participate in the reliquefaction of the gas in the compressed vapor state.
- the first heat exchanger makes it possible to pre-cool the gas in the compressed vapor state on the one hand and to heat the gas in the vapor state at the tank outlet on the other hand. Precooling the compressed gas facilitates its subsequent heat treatment, in particular its reliquefaction.
- the first heat exchanger thus makes it possible to improve the overall efficiency of the management system because the low temperature of the gas in the vapor state at the outlet of the tank participates indirectly in the reliquefaction of gas in the compressed vapor state and this via the heat exchange taking place in the first heat exchanger.
- the cooling circuit can have several functions such as participating in the reliquefaction of the gas in vapor state circulating in the heat treatment circuit, or even in managing the pressure of the tank.
- the gas in the liquid state of the tank is taken by the pump and circulates within the cooling circuit, this pump can for example be immersed at the bottom of the tank.
- the gas in the liquid state can pass through the second heat exchanger, which is also crossed by the gas in the vapor state circulating in the heat treatment circuit.
- This heat exchange thus makes it possible to reliquefy the gas in the vapor state without leading to the evaporation of the gas in the liquid state circulating in the cooling circuit.
- the advantage of the heat treatment system according to the invention is the presence of two portions within which the gas circulates in the vapor state at different pressures.
- the second portion Due to the pressure of the gas in the vapor state circulating there, the second portion is capable of ensuring the expansion of the gas using the expansion member. Pressurization by the second compression stage then expansion subsequently promotes the reliquefaction of the unconsumed gas, for example when the duration of the journey is long and/or the quantity of gas in the vapor state generated in the sky tank is high. If the journey is short, for example less than two days, and/or the quantity of gas in the vapor state generated in the tank head is low, then it is preferable to raise the pressure of the gas in the vapor state. steam only via the first compression stage and to circulate it within the first portion.
- the second heat exchanger is connected to the tank by a return branch comprising a termination opening into the tank and an orifice disposed on a portion of the return branch present in the tank.
- the orifice is arranged at the end of the return branch present in the tank. This allows the liquefied gas leaving the second heat exchanger to return to the tank.
- the orifice is a calibrated orifice. Thanks to this calibrated orifice, we can finish the expansion of the liquefied gas in the return branch at the level of the tank and thus reduce or even eliminate the vaporization of a fraction of the liquefied gas during its expansion.
- the first portion of the heat treatment circuit is devoid of an expansion member.
- the gas in the vapor state which circulates in the first portion is expanded by the pressure losses of this first portion, but the system does not include an active member which generates expansion within the first portion.
- the first portion comprises a first valve and the second portion comprises a second valve, the first valve and the second valve being configured to control the circulation of gas within said portions.
- the first valve and the second valve are capable of being opened or closed.
- the heat treatment circuit comprises a point of divergence from which the first portion and the second portion begin, the point of divergence being arranged between the first heat exchanger and the second heat exchanger.
- This is a first embodiment of the heat treatment circuit. Regardless of what pressure the gas in the vapor state is high, it passes through at least the first heat exchanger while circulating within a single portion of the heat treatment circuit. It is only downstream of the first heat exchanger that the gas in vapor state circulates in the first portion or in the second portion.
- the first portion and the second portion begin respectively at the first compression stage and at the second compression stage of the compression device. This is therefore a second embodiment of the heat treatment circuit. Each portion is directly attached to the compression device, at the level of its own compression stage.
- the first portion and the second portion meet at a point of convergence.
- the two portions extend in parallel to each other until the point of convergence. Several locations can be chosen within the heat treatment circuit for said convergence point.
- the point of convergence is arranged between the first heat exchanger and the second heat exchanger. In other words, in this configuration, it is a single portion of the heat treatment circuit which passes through the second heat exchanger. According to one aspect, if the heat treatment circuit is provided with a divergence point, then the convergence point is arranged between the divergence point and the second heat exchanger.
- the point of convergence is arranged downstream of the second heat exchanger.
- the first portion and the second portion therefore pass through the second heat exchanger before joining downstream of it.
- the heat treatment circuit comprises at least a first branch connected to the first compression stage of the compression device and a second branch connected to the second compression stage of the compression device, the first branch and the second branch joining at a junction point of the heat treatment circuit arranged between the compression device and the point of divergence.
- a configuration is specific to the first embodiment, where the first portion and the second portion are not directly connected to the compression device.
- the first branch and the second branch that implement this function.
- the junction point is located on the heat treatment circuit, downstream of the compression device and upstream of the divergence point.
- the heat treatment circuit begins from the first branch and the second branch which meet at the junction point. Then, the heat treatment circuit separates at the point of divergence and forms the first portion and the second portion which extend to the point of convergence.
- the first branch comprises a first valve and the second branch comprises a second valve, the first valve and the second valve being configured to control the circulation of gas within said branches.
- the first valve and the second valve are arranged on the first branch and the second branch and ensure the management of the circulation of gas within those -this.
- the first portion and the second portion of the heat treatment circuit each comprise a pass of the first heat exchanger and/or the second heat exchanger.
- the first portion and the second portion can both pass through the first heat exchanger and/or the second heat exchanger.
- the latter can therefore be two-pass or three-pass heat exchangers, with one pass per portion and one pass forming part of the supply circuit for the first heat exchanger, and one pass forming part of the cooling circuit for the second heat exchanger.
- the management system comprises a third heat exchanger configured to carry out a heat exchange between the gas in the liquid state circulating in the cooling circuit and a refrigerant fluid circulating in a cooling loop.
- This third heat exchanger makes it possible to sub-cool the gas in the liquid state, for example with the aim of improving the reliquefaction of the gas in the vapor state circulating through the second heat exchanger by circulating the gas in the subcooled liquid state within this same second heat exchanger.
- Such a configuration can be used for example in the event of a large quantity of gas in the vapor state to be reliquefied.
- the gas in the subcooled liquid state can also return to the tank in order to lower the overall temperature thereof and thus reduce the pressure of the tank.
- the refrigerant fluid circulating in the cooling loop used to subcool the gas in the liquid state can for example be nitrogen.
- the management system comprises an additional branch connecting the first compression stage of the compression device to the tank, the management system further comprising a heat exchanger configured to carry out a heat exchange between the gas in the vapor state circulating in the additional branch and a refrigerant fluid circulating in a reliquefaction loop.
- a heat exchanger configured to carry out a heat exchange between the gas in the vapor state circulating in the additional branch and a refrigerant fluid circulating in a reliquefaction loop.
- the presence of the additional branch and the heat exchanger can also be useful, for example, in the case where there is too little gas in vapor state circulating from the tank to the compression device to carry out pre-cooling. effective.
- the heat exchanger can also be used when the gas in the liquid state contained in the tank is at a temperature too high to correctly reliquefy the gas in the vapor state circulating in the heat treatment circuit and when said gas is liquid state cannot be subcooled.
- the reliquefaction loop can be passed through by a refrigerant fluid, for example nitrogen.
- the additional branch extends to the tank so that the gas, once reliquefied within the heat exchanger, can circulate in the liquid state to the tank.
- the supply circuit comprises at least one compression element arranged at least partially in parallel with the compression device.
- the compression element notably has a redundancy function in the event of failure of the compression device.
- the compression element can also assist the compression device in the event of a strong power requirement for the gas consuming device or gas consuming devices.
- the compression element is connected to the first compression stage of the compression device. This is an output of the compression element which is connected to the first compression stage of the compression device.
- the compression element compresses the gas to the same pressure level as the first compression stage, for example in order to be able to supply a gas consuming device at low pressure or to circulate gas. compressed gas within the first portion.
- the heat treatment circuit joins the cooling circuit downstream of the second heat exchanger. At this stage, the gas circulating in the heat treatment circuit is reliquefied.
- the cooling circuit extends to the tank in order to guarantee a return of reliquefied gas and gas in liquid state circulating in the cooling circuit to the tank.
- the heat treatment circuit comprises a separation device, an inlet of which is arranged downstream of the second heat exchanger.
- the heat treatment circuit can in fact comprise such a separator making it possible to separate the gas phase from the liquid phase of the gas circulating in the heat treatment circuit, and this after said gas has passed through the second heat exchanger.
- the separation device can be used in the event of partial reliquefaction of the gas circulating in the heat treatment circuit in order to retain the fraction of gas which has not reliquefied.
- the separation device comprises a steam outlet, the heat treatment circuit comprising a first path connecting the steam outlet of the separation device to the supply circuit at a point located between the tank and the first exchanger heat. The first path makes it possible to recirculate the gas in the vapor state which has not reliquefied to the supply circuit in order to be consumed by the gas consuming device or to lead to a new attempt at reliquefaction.
- the separation device comprises a liquid outlet, the heat treatment circuit comprising a second path connecting the liquid outlet of the separation device to the cooling circuit.
- the reliquefied gas therefore leaves the separation device in the liquid state and circulates in the second channel in order to return to the tank via the cooling circuit.
- the invention also covers a floating structure comprising at least one tank, at least one gas-consuming device and a management system as described above.

- the low pressure gas consuming device 5 can for its part be a generator supplying the floating structure with electricity.
- the management system 1 comprises a power supply circuit 6 extending between the tank 2 and the gas-consuming devices 4, 5.
- the power supply circuit 6 comprises a compression device 7 making it possible to suck up the gas in the vapor state contained in the sky 3 and the tank 2 and to compress it up to a pressure compatible with the needs of the device consuming gas at high pressure 4, for example above 250 bars, or of the low pressure gas consuming device 5, in particular between 7 and 20 bars.

- the gas in the vapor state passes through the entire compression device 7 and leaves via the third outlet 58 to reach the pressure compatible with the supply of the high pressure gas consuming device 4.
- the gas in the vapor state can reach a pressure of between 250 and 400 bars.
- the gas in the vapor state compressed by the first compression stage 11 has a pressure of between 7 and 20 bars while the gas in the vapor state compressed by the second compression stage 12 has a pressure of between 120 and 150 bars .
- the first compression stage 11 also makes it possible to raise the pressure of the gas in the vapor state to a value compatible with supplying the low-pressure gas consuming device 5.
- the management system 1 also includes a heat treatment circuit 8.
- the heat treatment circuit 8 is connected to the power supply circuit 6, more particularly at the level of the compression device 7.
- the heat treatment circuit 8 comprises a first branch 9 and a second branch 10, respectively connected to the first outlet 56 of the compression device 7 disposed downstream of the first compression stage 11 and upstream of the second compression stage 12, and at the second outlet 57 of the compression device 7 disposed downstream of the second compression stage 11 and upstream of the third compression stage 13.

- the second heat exchanger 16 comprises two passes.
- the management system 1 comprises a cooling circuit 17 within which circulates gas in the liquid state taken from the tank 2.
- the cooling circuit 17 comprises a pump 18, advantageously immersed at the bottom of the tank 2 and which circulates gas in the liquid state within the cooling circuit 17.
- the cooling circuit 17 one of them is to participate in the reliquefaction of the gas to be the vapor state circulating in the heat treatment circuit 8.
- the gas in the liquid state circulating in the cooling circuit 17 can thus pass through the second heat exchanger 16 within which the heat exchange with the gas takes place in the vapor state circulating in the heat treatment circuit 8.
- the gas in the vapor state is then reliquefied.
- the management system 1 comprises a third heat exchanger 19, that the gas in the liquid state circulating in the cooling circuit 17 can cross or go around.
- the third heat exchanger 19 makes it possible to sub-cool the gas in the liquid state in order to compensate for the calories captured by the gas in the liquid state during the heat exchange occurring within the second heat exchanger 16.
- the system 1 according to the invention can comprise a cooling loop 20 which passes through the third heat exchanger 19, such a cooling loop 20 being traversed by a refrigerant fluid ensuring the sub-cooling of the gas to the liquid state.
- the refrigerant fluid circulating in the cooling loop 20 can for example be nitrogen.
- the choice of sub-cooling the gas in the liquid state via the third heat exchanger 19 or not is also dependent on the quantity of gas in the vapor state generated in the tank 2 and/or the duration of the journey of the floating work, just as for the choice of the level of pressure applied to the gas in the vapor state intended to be reliquefied.
- Such a choice makes it possible to determine whether or not it is necessary to use the third heat exchanger 19 and the cooling loop 20 to ensure the reliquefaction of the gas in the vapor state circulating in the heat treatment circuit 8. This avoids thus to use this cooling loop 20 in a superfluous manner when this is not essential for the reliquefaction of the gas in the vapor state, which limits energy consumption.
- the reliquefied gas joins the cooling circuit 17, also at the outlet of the second heat exchanger 16.
- the cooling circuit 17 extends to the tank 2 so that the return of the gas to the liquid state can take place within it.
- the cooling circuit 17 therefore comprises at least one termination 29 which may be an orifice 30 arranged at the bottom of the tank 2.
- the management system 1 can be configured to provide the gas to the latter.
- the management system 1 can include an additional power supply circuit 33.
- the additional supply circuit 33 comprises an additional pump 35, a high pressure pump 36 and a high pressure evaporator 37.
- the additional pump is an additional pump 35, a high pressure pump 36 and a high pressure evaporator 37.
- the high pressure evaporator 37 makes it possible to evaporate the gas in the liquid state placed under pressure. high pressure so that the gas passes into the vapor state and can be consumed by the high pressure gas consuming device 4.
- the additional pump 35 and the pump 18 of the cooling circuit 17 are separate and distinct pumps. According to an alternative, the system does not have an additional pump dedicated to the additional power circuit 33.
- the additional power circuit 33 is connected to the cooling circuit 17, between an outlet of the pump 18 and an inlet of the second heat exchanger 16 and it is the pump 18 which, in addition to its initial function, takes gas in the liquid state from the tank 2 to supply it to the high pressure pump 36.
- Figure 2 represents a second embodiment of the management system 1 according to the invention.
- the second embodiment differs from the first embodiment in that the first portion 51 and the second portion 52 extend over the entirety or substantially the entirety of the heat treatment circuit 8.
- the second embodiment of the management system 1 illustrated in Figure 2 therefore does not include the first branch, the second branch, the junction point and the divergence point.
- the first portion 51 and the second portion 52 which are directly connected to the compression device 7, respectively to the first outlet 56, at the level of the first compression stage 11, and to the second outlet 57, between the second stage of compression 12 and the third compression stage 13.
- the first valve 41 and the second valve 42 are always present in order to control the circulation of the gas in the vapor state within the first portion 51 and the second portion 52.
- the heat treatment circuit 8 comprises a flow regulating member 40 disposed downstream of the point of convergence 55 between the first portion 51 and the second portion 52. This flow regulating member 40 adapts the pressure and the flow rate within the heat treatment circuit 8 so as to bring this pressure closer to the pressure which reigns within the tank 2.
- This flow regulation member 40 is arranged downstream of the branch of the heat treatment circuit 8 which passes through the second heat exchanger 16, and upstream of a mixing point 39 between the heat treatment circuit 8 and the cooling circuit 17.
- the first portion 51 and the second portion 52 thus extend in parallel to each other, including within the first heat exchanger 14 and the second heat exchanger 16.
- the heat exchangers 14, 16 are thus composed of three passes, at the rate of one pass per portion of the heat treatment circuit 8, of a pass where the gas circulates in the vapor state circulating in the supply circuit 6 upstream of the compression device 7 for the first heat exchanger 14, and a pass where the gas in the liquid state circulates circulating in the cooling circuit 17 for the second heat exchanger 16.
- the point of convergence 55 between the first portion 51 and the second portion 52 is arranged downstream of the second heat exchanger 16.
- the heat treatment circuit 8 subsequently joins the cooling circuit 17.
- the positioning of the point of convergence 55, but also that of the junction point 53 and the point of divergence 54 illustrated in Figure 1, may differ in a non-exhaustive manner from what is illustrated in Figures 1 and 2.
- the first heat exchanger 14 and the second heat exchanger 16 may comprise two or three passes.
- the expansion member 15 is always positioned at the level of the second portion 52 and ensures the expansion of the gas compressed by the second compression stage 12.
- the level of compression of the gas by the compression device 7 as well as the use of the third heat exchanger 19 and the cooling loop 20 are dependent for example on the duration of the journey of the floating structure and the quantity of gas in the vapor state generated in the sky 3 of tank 2.
- Figures 3 to 6 represent a variant of the first embodiment or a variant of the second embodiment of the management system 1 according to the invention. Only the structural and functional differences compared to what has been mentioned previously will be described about these variants. We will therefore refer to the description of Figure 1 and/or Figure 2 for all the characteristics not detailed below concerning these variants.
- Figures 3 and 4 thus respectively represent a first variant of the first embodiment and a first variant of the second embodiment.
- This first variant differs from what has been described previously in particular by the absence of the third heat exchanger making it possible to sub-cool the gas in the liquid state circulating in the cooling circuit 17.
- this comprises an additional branch 48 connected to the first output 56 of the compression device 7, in parallel with the first branch 9 or the first portion 51 according to the embodiment, and which extends to the tank 2.
- This additional branch 48 conducts the gas in the vapor state through a heat exchanger 49, which is configured to carry out a heat exchange between the gas in the vapor state and a refrigerant fluid circulating in a reliquefaction loop 50.
- the reliquefied gas circulates in the additional branch 48 until returning to the tank 2.
- the additional branch 48 and the heat exchanger 49 can thus be used when it is not possible to sub-cool the gas in the liquid state within the cooling circuit 17, which can lead to poor reliquefaction.
- gas in the state steam passing through the second heat exchanger 16 for example in a case where it is desired to limit the heating of the cargo or in the case of gas in the vapor state in too large a quantity.
- the operation of the management system 1 can also depend on the duration of the journey of the floating structure.
- a compression element 32 arranged at least partially in parallel with the compression device 7, in particular at least with the first compression stage 11. This compression element 32 ensures at least partial redundancy with the compression device 7. This compression element 32 is optional.
- the compression element 32 is configured to compress the gas in the vapor state to a pressure identical or similar to that delivered by the first compression stage 11 of the compression device 7.
- An admission of the compression element 32 is connected to the supply circuit 6 at a point located between the outlet of the first heat exchanger 14 and an inlet of the compression device 7.
- the compression element 32 is also capable of supplying the device consuming low pressure gas 5 in gas in the vapor state, the supply circuit 6 then comprising a line connecting an outlet of the compression element 32 with an inlet of the device consuming low pressure gas 5.
- the gas in the vapor state compressed by the compression element 32 can also circulate in the first branch 9 or directly in the first portion 51 depending on the embodiment of the management system 1. Finally, the gas in the vapor state vapor compressed by the compression element 32 can also join the compression device 7 and be further compressed by the latter by means of the second compression stage 12, to circulate in the second branch 10 or the second portion 52, or be more compressed by the third compression stage 13 to supply the high pressure gas consuming device 4.
- the compression element 32 is shown in Figures 3 and 4, but can also be integrated into the embodiments illustrated in Figures 1 and 2, as well as the variants described below.
- Figures 5 and 6 respectively represent a second variant of the first embodiment and a second variant of the second embodiment.
- This second variant differs from what is illustrated in Figures 1 and 2 in that the heat treatment circuit 8 comprises at least one separation device 21 arranged downstream of the second heat exchanger 16.
- Such a separation device 21 has the advantage of preventing a fraction of gas in the vapor state from circulating to tank 2.
- the mainly reliquefied or completely reliquefied gas can circulate to the separation device 21.
- the latter allows to separate a liquid fraction from a vapor fraction of the gas if the latter is not entirely reliquefied.
- the separation device 21 comprises a vapor outlet 23 authorizing the exit of the vapor fraction out of the separation device 21 and a liquid outlet 24 authorizing the exit of the liquid fraction out of the separation device 21.
- the steam fraction if it is present in the separation device 21, can exit via the steam outlet 23 and circulate within a first channel 25.
- the first channel 25 is connected to the supply circuit 6 and allows the recirculation of the gas in the non-reliquefied vapor state within said supply circuit 6 so that said gas is consumed or reliquefied.
- the liquid fraction present in the separation device 21 can for its part exit through the liquid outlet 24 and circulate within a second path 26 which connects the separation device 21 to the cooling circuit 17. After joining the latter, the reliquefied gas then circulates to tank 2 via orifice 30.
- the separation device 21 and the two channels 25, 26 are illustrated within a management system equipped with the third heat exchanger 19. It is nevertheless entirely possible to combine the first variant and the second variant of the management system 1 illustrated in Figures 3 to 6, and thus to implement a management system 1 with the separation device 21, the two channels 25, 26, as well as the additional branch 48 and the heat exchanger 49, whatever the embodiment of said management system 1.
- Figure 7 represents a management system similar to Figure 1 and additionally comprising a calibrated orifice 60.
- the management system 1 comprises the second heat exchanger 16 connected to the tank 2 by a return branch comprising a termination 29 opening into the tank and an orifice 30 disposed on a portion of the return branch present in the tank.
- the orifice 30 is arranged at the end of the return branch present in the tank.
- the orifice 30 is a calibrated orifice 60.
- the reduction in pressure will be 2 bars.
- the reduction in pressure will be 2.2 bars.
- the reduction in pressure will be 2.1 bars.
- the calibrated orifice 60 is illustrated only in Figure 7 but it is nevertheless entirely possible to combine the presence of the calibrated orifice 60 with the variants of the first mode and the second mode as well as its first variant of the management system 1 illustrated in Figures 1 to 5.
- the invention achieves the goal it set for itself, and proposes a system for managing a gas contained in a floating structure that can optimize the consumption necessary to liquefy the gas not consumed by the consuming device of the floating structure, according to conditions linked to the duration of a journey of the floating structure and/or to a quantity of gas in the state steam present in the tank head.
- Variants not described here could be implemented without departing from the context of the invention, since, in accordance with the invention, they include a management system according to the invention.
