Definitions

  • the present invention relates to a fluid supply assemblage for the storage and supply of a fluid and a floating transportation vessel, such as an off-shore supply vessel, comprising such a fluid supply assemblage.
  • the present invention further relates to a method for assembling such a fluid supply assemblage, and a method of transferring a fluid between a first floating moveable structure and a second floating structure using such a fluid supply assemblage.
  • the fluid itself may require special considerations, for example because it may be hazardous, due to its chemical nature, such as flammability, and/or it may be have particular handling requirements, for example if it is a cryogenic fluid.
  • the off-shore structures may be those used in the production of hydrocarbons from sources such as oil and natural gas.
  • refrigerant substance which can be used in a variety of cooling processes.
  • a refrigerant substance may be both a hydrocarbon fluid and a cryogenic fluid.
  • Cryogenic hydrocarbon refrigerant substances such as ethane and propane are particularly useful in the liquefaction of natural gas.
  • Natural gas is a useful fuel source, as well as being a source of various hydrocarbon compounds. It is not unusual to liquefy natural gas in a liquefied natural gas (LNG) plant at or near the source of a natural gas stream to form a liquefied natural gas stream. Liquefied natural gas can be stored in cryogenic tanks, and/or transported in carrier vessels, at atmospheric pressure and a temperature of about -162 °C.
  • LNG liquefied natural gas
  • natural gas comprising predominantly methane
  • the purified gas is processed through a plurality of cooling stages where it is cooled against refrigerant in heat exchangers to progressively reduce its temperature until liquefaction is achieved.
  • the liquid natural gas is then further cooled and expanded to final atmospheric pressure suitable for storage and transportation.
  • the liquefaction of natural gas is carried out in an on-shore facility.
  • the natural gas must be transported from the natural hydrocarbon reservoir where it extracted to the liquefaction and optionally pre-treatment facility.
  • Hydrocarbon reservoirs producing natural gas may be found off-shore.
  • An off-shore structure, preferably a floating structure, for the processing of natural gas is advantageous because it provides an off-shore alternative to on-shore liquefaction plants.
  • a floating structure for the liquefaction of natural gas can be moored off the coast, or close to or at a gas field, in waters deep enough to allow off-loading of the LNG product onto a carrier vessel. It also represents a movable asset, which can be relocated to a new site when the gas field is nearing the end of its productive life, or when required by economic, environmental or political conditions.
  • floating structures examples include a Floating Liquefaction Storage Off-shore (FLSO) facility which combines the natural gas liquefaction process, storage tanks, loading systems and other infrastructure into a single floating structure.
  • FLSO Floating Liquefaction Storage Off-shore
  • a Floating Liquefaction of Natural Gas (FLNG) facility or a Floating Production, Liquefaction, Storage and Off-loading (FPLSO) facility further contains other processing capabilities necessary to prepare the natural gas being produced from the natural hydrocarbon reservoir for the liquefaction process.
  • FLNG Floating Liquefaction of Natural Gas
  • FPLSO Floating Production, Liquefaction, Storage and Off-loading
  • the natural gas liquefaction process may utilise a refrigerant to reduce the temperature of the natural gas to cryogenic temperatures.
  • the refrigerant is typically a multicomponent composition comprising a plurality of refrigerant components.
  • the refrigerant components may comprise one or more hydrocarbon refrigerant substances, each mainly consisting of one refrigerant component such as ethane and propane.
  • the natural gas itself may provide a source of such hydrocarbon refrigerant substances, such that they can be produced as part of the liquefaction process.
  • the liquefaction facility may be located in an off-shore location, for example on a floating off-shore facility, such as a FLSO facility.
  • US Patent Application Publication No. 2011/0132033 discloses a process for conditioning an ethane-rich stream for storage and transportation.
  • the conditioned ethane-rich stream may be transported using a pipeline, a truck, a rail car, or tanker ship.
  • the pipeline, truck, rail car, or tanker ship may be one which is normally configured to transport LNG, CNG, NGLs, or any other type of hydrocarbons.
  • the vessels that contain the conditioned ethane on the transport vehicles may be insulated to minimize heat ingress and ethane boil-off. It is disclosed that in some cases, the transport vehicles may be equipped with recycle systems and cooling systems to re-liquefy the boiled-off ethane vapour.
  • Refrigerated tanks require refrigeration systems to maintain the full cargo in the liquid state adding to their operational costs. Pressurised tanks are heavy in order to contain the pressurised cargo. They therefore have a low cargo to tank weight ratio and have risks associated with the handling of pressurised cargo. It will be appreciated that liquefied hydrocarbon gas and hydrocarbon vapours can be flammable.
  • hydrocarbon carrier vessels such as ethylene carriers, which can be repurposed to carry ethane, typically have a minimum cargo size of approximately 2000 m 3 .
  • the monthly average requirements of a hydrocarbon refrigerant substance for a liquefaction facility may be considerably less than the cargo carrying capacity of such a hydrocarbon carrier vessel, for instance 10% to 15% or possibly less by volume, while being greater than that of a standard vessel (container) for transporting cryogenic fluid.
  • the use of hydrocarbon carrier vessels as the transporter may thus not be practical if quantities of hydrocarbon less than that of a carrier vessel are to be supplied to a floating structure, for instance on a monthly basis.
  • the present invention provides a fluid supply assemblage for the storage and supply of a fluid, said fluid supply assemblage comprising at least:
  • the invention further provides a floating transportation vessel, such as an off-shore supply vessel, comprising a fluid supply assemblage for the storage and supply of a fluid, said fluid supply assemblage comprising at least:
  • the present invention provides a method for assembling the fluid supply assemblage according to the first aspect, comprising at least the steps of:
  • a method of transferring a fluid between a first moveable floating structure, and a second floating structure comprising a liquefaction facility comprising at least the steps of:
  • a fluid supply assemblage is proposed involving a plurality of intermodal containers and a transfer manifold, for transferring a fluid, for instance from one floating structure to another.
  • the intermodal containers each have a tank for the storage of the fluid, which tanks are connected to a transfer manifold.
  • the transfer manifold has a plurality of manifold inlets and a manifold outlet. The manifold outlet is in fluid communication with at least two tanks of the plurality of intermodal containers via the transfer manifold.
  • the term "assemblage" is an apparatus of assembled components such as an arrangement of interlinked components.
  • the fluid supply assemblage comprises a plurality of intermodal containers and a transfer manifold, in which at least one of the one or more, preferably all, of the plurality of intermodal containers are removable from the fluid supply assemblage and are replaceable.
  • tank is a storage container for a fluid, the fluid preferably being in liquid state under its own vapour pressure.
  • the tank forms part of the intermodal container, such that the intermodal container comprises the tank.
  • intermodal container means a movable container which can be transported from one location to another, and from one transporter to another, without off-loading and reloading of the contents of the tank from and to the container (in this case the fluid).
  • An intermodal container is advantageous because it can be used in a global containerised intermodal freight transport system and used with and transferred between any mode of transport such as ship, rail or truck.
  • the plurality of intermodal containers comprising the fluid can be transported from any location, such as that of the manufacture of the fluid, to a location at which the intermodal containers are incorporated into the fluid supply assemblage.
  • intermodal containers allows a modular construction of the fluid supply assemblage, providing flexibility in the number of containers to be attached to the transfer manifold, and therefore the quantity of fluid to be supplied. This is achieved by fluidly connecting at least two of a plurality of intermodal containers via a single transfer manifold.
  • the manifold inlets of the plurality of manifold inlets are typically in fluid communication with a single manifold outlet.
  • the transfer manifold is in fluid communication with a fluid transfer connector via the manifold outlet, so that fluid may be discharged, preferably simultaneously discharged, from at least two of the intermodal containers to the fluid transfer connector.
  • the assembling of the fluid supply assemblage can be done at ease before transferring the fluid.
  • the assembling can for instance be done in a safe area, such as in a relatively protected area of a port or harbour, such that the transferring of the fluid from the tanks can be done relatively quickly and safely, without the need to connect and/or disconnect hoses to the tanks during the transferring of the fluid.
  • the plurality of intermodal containers can be interlinked, for instance by mechanically attaching an intermodal container to at least one, typically one or two other intermodal containers.
  • the fluid supply assemblage may comprise from 2 to 20, more preferably from 5 to 10 intermodal containers, typically of 20 or 40 kliter (20 m 3 ) capacity each.
  • the fluid supply assemblage is particularly suitable when the fluid is a hydrocarbon fluid, preferably for at least 95 mol% consisting of hydrocarbons.
  • the hydrocarbon fluid preferably comprises one or more hydrocarbon components, more preferably one or more hydrocarbon refrigerant components.
  • the one or more hydrocarbon components or hydrocarbon refrigerant components may be selected from the group comprising ethane, ethylene, propane, butane, and isobutene.
  • the hydrocarbon fluid may comprise at least two of said hydrocarbon refrigerant components.
  • the fluid may be a cryogenic fluid, preferably a cryogenic hydrocarbon fluid.
  • cryogenic is intended to mean a fluid at a temperature of lower than -30 °C, more preferably at a temperature of lower than -80 °C.
  • the temperature may be selected ⁇ -88 °C, typically in a range of from -100 °C to -88°C.
  • the temperature may be selected ⁇ -42 °C, typically in a range of from -100 °C to -42°C.
  • the fluid may be at a pressure in the range of from about 1 to 2 bar.
  • the balance of the hydrocarbon fluid may be provided by one or more further components as defined elsewhere herein.
  • Providing the fluid, particularly a cryogenic fluid such as a cryogenic hydrocarbon refrigerant substance, stored in and supplied from in an intermodal container, allows the transportation of the hydrocarbon in much smaller and variable quantities than that required by a hydrocarbon carrier vessel. Furthermore, it is intended to supply the fluid in a form best suited for storage and use as a refrigerant substance, namely in the liquid state and at a pressure in the range of from about 1 to 2 bar.
  • the fluid is preferably in a conditioned state, forming a conditioned fluid.
  • the fluid is a conditioned hydrocarbon fluid.
  • the conditioned fluid, particularly the conditioned hydrocarbon fluid is preferably conditioned such that it is in the liquid state and at a pressure in the range of about 1 to 2 bar. It will be apparent that conditioned hydrocarbons such as ethane or propane i.e. which are in the liquid state and at a pressure of about 1 to 2 bar are cryogenic fluids.
  • the fluid, particularly a hydrocarbon fluid or conditioned hydrocarbon fluid may consist for at least 95 mol%, preferably for at least 98 mol%, of a main hydrocarbon component.
  • a main hydrocarbon component are ethane, ethylene, propane, propylene, butane or isobutene, and may be suitable for use as a refrigerant substance without further fractionation.
  • the main hydrocarbon component is the one which constitutes the highest proportion, by mol%, of the fluid.
  • the use of the fluid supply assemblage may thus dispense with the requirement for fractionation equipment at the destination, providing a fluid comprising the desired composition for operation as a refrigerant.
  • the conditioned ethane comprises less than 50 ng/m 3 , preferably less than 10 ng/m 3 , and more preferably less than 5 ng/m 3 mercury.

  • the assemblage may comprise more or less containers, such as 2, 4, 5, 6, 7, 8, 9, 10 or more than 10.
  • the intermodal containers may be of any size, but are typically 20 feet (6.10 m) or 40 feet (12.19 m) in length for use in a global containerised intermodal freight transport system.
  • Each intermodal container 10a, 10b, 10c comprises a tank 15a, 15b, 15c for a fluid.
  • the tank 15 is thermally insulated, more preferably multi-layer thermally insulated, when it is to hold cryogenic fluid.
  • the thermal insulation may include a vacuum jacket (not shown).
  • the tank 15 is vapour tight.
  • intermodal containers comprising a tanks that are thermally insulated and/or vapour-tight, provides the advantage that the fluid may be transported and supplied in the form in which it can be most readily transferred, stored and used at its destination such as a floating structure.
  • the fluid may be a cryogenic liquid.
  • the tank 15 may comprise one or more pressure relief valves, comprising at least a lowest pressure relief valve (not shown). Such a tank will have an associated hold time for a particular fluid.
  • the hold time is the time elapsed from loading until the pressure under equilibrium conditions in the tank reaches the level of the lowest pressure relief valve setting. After the lowest pressure relief valve is opened, the loss of fluid to evaporation can be quantified by a net evaporation rate. In order to prevent escape of fluid vapour from the tank, the residence time of fluid in the tank 15 should not exceed the hold time.

  • the fluid supply assemblage 1 further comprises a transfer manifold 50.
  • the transfer manifold 50 comprises a plurality of manifold inlets 55.
