    Ship carrying refueling tanks to ships powered by liquefied natural gas (LNG), as well as a LNG liquefied natural gas charging station. The invention consists of an LNG tanker carrying vessel that is used as a LNG liquefied natural gas charging station as for refueling operations to LNG-propelled vessels in operations that are normally known as bunkering. In the use as a liquefied natural gas charging station, the ship is supplied from an LNG cargo ship that fills the ship's cisterns and approaching the coast these cisterns are unloaded for the supply of final consumers. In bunkering or refueling operations to ships propelled to LNG liquefied natural gas, the tanks and their pumping equipment themselves or by means of a centralized pumping system on the ship, transfer the gas from the tanks to the vessel to be refueled.

    [0002] BOAT PORTA CISTERNAS OF REPOSTAJE TO BOATS PROPULSED TO LNGED NATURAL GAS (LNG), AS WELL AS LNG LNGED NATURAL GAS LOAD STATION
    [0003]
    [0004] TECHNICAL FIELD OF THE INVENTION
    [0005]
    [0006] The invention falls within the technical field of natural gas transportation and logistics systems more specifically in the transport of LNG liquefied natural gas from gas producing sites or countries to customers or final consumers, when said consumers are located in locations of difficult sea access.
    [0007]
    [0008] The transport and distribution ship of the invention also falls within the field of maritime means used for the transport and distribution of liquefied natural gas among customers or final consumers that can be found near or far from the coast, but dispersed in a wide area of islands, among which logistic transport can be done by sea.
    [0009]
    [0010] The ship of the invention also falls within the technical field of refueling other ships, more specifically ships propelled with LNG liquefied natural gas.
    [0011]
    [0012] STATE OF THE PREVIOUS TECHNIQUE
    [0013]
    [0014] The transport of liquefied natural gas LNG or in English Liquified Natural Gas LNG, from the countries producing natural gas to the consuming countries is done through large ships called metanerosogaseros. In these vessels the gas must be maintained at a temperature of -161 C for long journeys, the natural gas being transported in a liquid state at a pressure higher than atmospheric. The large methane or gas vessels have a loading capacity of between 30,000 and 266,000 m3.
    [0015]
    [0016] The LNG is transported in tanks that withstand these low temperatures, keeping the LNG at the temperature at which it has been charged, that is, at approximately -161 ° C throughout the entire navigation, but depending on its temperature and pressure, a part of the liquid is evaporated by boiling. The evaporated gas is usually used to propel the ship, either consuming it in boilers or using it in engines that use gas as fuel.
    [0017]
    [0018] Usually, when the transported gas is discharged into the port, a small amount of the cargo is left in the tanks which, when evaporating during the trip, will keep the tanks cold, only a more intense final short cooling being necessary before reloading the LNG This is achieved with the same remaining load, removing it from the tanks, which, when evaporated, cools them to the temperature required for the load.
    [0019]
    [0020] These large methane or gas ships need ports with a large draft and, in addition, due to the cargo they carry, both the loading of liquefied natural gas and its discharge are usually made in cargo terminals away from ports, which are connected through pipes with mainland.
    [0021]
    [0022] For the transport of LNG to customers or final consumers, we find basically two systems, the first, where piped gas reaches a large number of consumers such as homes, industries, shopping centers, etc ... and that arrives coming from regasification plants, or directly from gas pipelines connected to gas extraction plants. However, in cores away from large consumption points or that are isolated from the gas pipeline network, it is not profitable to invest in piped supply networks, for which LNG storage tanks that are usually supplied by trucks are used cistern that regularly refill such deposits. The invention described herein is intended to serve these types of customers.
    [0023]
    [0024] PCT patent application WO2016 / 036690 is known, referring to a hydrocarbon maritime transport system in a cryogenic state, that is, it is a transport of liquefied natural gas on a small scale, a system that includes a plurality of cargo ships with container tanks of liquefied gas with a capacity of 25,000 m3 or less and a transfer vessel, these small-scale LNG cargo ships collaborating with the transfer vessel for gas distribution to the mainland facilities, where the gas is discharged and regasified smoothie. This system facilitates the supply of natural gas to low-lying coastal areas, which makes its use appropriate in these circumstances, but a port infrastructure for the storage of liquefied natural gas and even a regasification plant from where the gas is distributed is still necessary. through channeling to the client or final consumer.
    [0025] The problem that can occur occurs when customers or final consumers are, for example, in very dispersed islands or archipelagos, where it is not profitable to make these port facilities in each and every one of those places, since it does not compensate economically, making it impossible to supply liquefied natural gas to a very large group of customers that are scattered throughout those islands.
    [0026]
    [0027] A second problem that exists in this type of consumers is that, although they have port facilities for the discharge of LNG, they do not have large LNG tankers, they also lack pipes that distribute LNG among consumers. Therefore, a LNG transport and distribution system that does not depend on each specific island or area to be supplied is advisable, being a completely autonomous system.
    [0028]
    [0029] In the Spanish patent application P201730936 of the same applicant, a liquefied natural gas (LNG) tanker-truck is shown only intended to be fed by a small LNG cargo ship and the tankers present on the ship are loaded through The loading posts. Once the ship approaches the mainland, the tankers are distributed on the mainland for supply to the users, returning to the vessel for subsequent filling and subsequent cycle start. The need has been observed that such a ship can be used as a LNG bunkering vessel, that is, as a means of refueling liquefied natural gas (LNG) to other vessels, propelled with liquefied natural gas (LNG).
    [0030]
    [0031] DESCRIPTION OF THE INVENTION
    [0032]
    [0033] In order to optimize the supply of LNG in remote areas such as islands, which lack port areas adapted to the supply of LNG, and from these to the rest of the island by trucks or through pipelines, and also be able to offer the possibility of refueling other vessels, the object of the invention has been developed, which consists of a refueling boat to ships propelled to liquefied natural gas (LNG), as well as a LNG liquefied natural gas charging station, comprising:
    [0034]
    [0035] - at least one LNG liquefied natural gas tank truck, located on the deck of the ship. - a single connection module that allows the ship to be connected to the LNG supply from a supply source or the ship to the vessel to be refueled.
    [0036] - at least one module for loading / unloading of LNG to and from tank trucks - at least one LNG distribution module that links the ship's connection module to the LNG supply or to the refueling vessel and the LNG loading / unloading module in tank trucks
    [0037] - means of access of tankers to the ship
    [0038] - means of leaving the tank trucks from the ship
    [0039]
    [0040] Characterizing said ship because
    [0041]
    [0042] - The ship's connection module has a liquefied natural gas connection that allows both the entry of liquefied natural gas into the ship and the exit of liquefied natural gas from the ship, as well as an evaporated natural gas (BOG) connection.
    [0043] - the distribution module being capable of transferring the liquefied natural gas between the connection module and the charging module, while the evaporated natural gas (BOG) flows between the charging module and the connection module in loading operations of the tank trucks. During refueling operations to other ships, the liquefied natural gas flows between the loading module and the connection module and the evaporated natural gas (BOG) of the tankers is connected to the evaporated natural gas collector (BOG) to control the Pressure.
    [0044] - The LNG loading module in tank trucks is a loading / unloading module of LNG to and from tank trucks.
    [0045]
    [0046] In refueling operations of LNG liquefied natural gas to other ships that are propelled by gas, called in English and internationally as bunkering operations, there is at least one pump for the transfer of liquefied natural gas between the tankers and the ship to be refueling with liquefied natural gas, this pump being the transfer of liquefied natural gas between the tankers and the ship to be refilled, at least one pump, which each tank truck for the transfer of the liquefied natural gas is arranged, preferably using as many transfer pumps as Tanker trucks supplying LNG to the ship to be refueled.
    [0047]
    [0048] Optionally, the ship has a circuit in the ship itself, formed by a collector that joins the loading / unloading modules of the bays with the connection module that links with the ship to be refueled, a circuit that has its own transfer pump of the liquefied natural gas between the tankers and the ship to be refilled with liquefied natural gas,
    [0049] The means of access and the means of exit of the tank trucks can be the same or the means of access are located at the opposite end to the means of exit of the tank trucks on the ship, whereby trucks can be used Small tank that can maneuver on the deck of the ship and exit through the access they have entered, or when larger tank trucks are used, with which it is difficult to maneuver when it needs a lot of space, the most appropriate arrangement would be truck entry at one end of the ship and exit at the opposite according to the orientation of the tractor units of the tank trucks.
    [0050]
    [0051] The means of access and exit of the tank trucks consist of rounded passage ramps of the tank trucks, since this will facilitate the lowering and raising of the trucks to the deck of the ship, each tank truck being placed in its loading position for loading of LNG.
    [0052]
    [0053] In filling operations of the tankers, the ship, with its empty tankers, will approach the small LNG cargo ship, which functions as a mothership, and the ship is connected to the small LNG cargo ship through the module connection of the ship to the supply of LNG, which includes:
    [0054]
    [0055] - at least one connection for LNG pipe through which the ship of said LNG that is loaded to the tankers, located on the deck of the ship, is supplied.
    [0056] - at least one gas discharge connection, from the vaporized natural gas. - cargo hoses between the ship and the small LNG cargo ship, which can be used for the transfer of LNG, and the gases from the vaporization of LNG.
    [0057] - at least one instrumentation and control module of the LNG transferred, and gas discharge carried out, that monitor and control the entire loading process.
    [0058]
    [0059] In refueling operations of other ships, or bunkering, the ship, with its full tank trucks, will approach the ship to be refueled and connected through the ship's connection module to the LNG supply, which comprises:
    [0060]
    [0061] - A connection module that incorporates the LNG collector that receives LNG liquefied natural gas from the tankers
    [0062] - A distribution module consisting of two LNG collectors one that connects the connection module with the vessel to be refueling, with the discharge module of each truck and the other BOG evaporated natural gas manifold that connects the BOG evaporated natural gas system of the tank trucks to control the pressure.
    [0063] - A pumping equipment for liquefied natural gas between the tankers and the refueling vessel, said pumping equipment formed by the LNG transfer pumps that carry the tankers, or a pumping equipment from the ship itself, formed by a collector that links the loading / unloading modules of the trucks with the connection module that links with the ship to be refueled,
    [0064] - LNG liquefied natural gas loading / unloading hoses
    [0065] - at least one module of instrumentation and fiscal control of the LNG transferred
    [0066]
    [0067] This ship does not have LNG tanks or tanks to supply fuel to a third party, but is a means of transferring and distributing LNG from the small LNG cargo ship and the tankers arranged on its deck.
    [0068]
    [0069] The deck of the ship is divided into one or multiple tanker truck loading positions, since the deck space can be optimized for the loading of multiple tank trucks, being able to adopt configurations with four, six, nine or more tanker truck loading posts , adapted to the size of the ship. At least one LNG loading / unloading module of the LNG corresponds to each tank truck. These modules for loading / unloading the LNG to or to the tankers, include:
    [0070]
    [0071] - an LNG loader / unloader to or from tank trucks
    [0072] - an evaporator of natural gas evaporated (BOG) of tank trucks
    [0073] - control and safety valves
    [0074] - a system for instrumentation, measurement and control of the LNG loading / unloading process in or from truck tanks
    [0075] - loading / unloading hoses and connection / disconnection systems between truck hoses and tanks
    [0076]
    [0077] To make the boat reversible and for trucks to enter and exit at both ends of the vessel, a configuration must be used in which the number of cargo modules aligned with the axis of the vessel is equal to the number of cargo positions of tank trucks plus one, making the vessel reversible both in its load and in its unloading of tank trucks.
    [0078] A final detail to be taken into account is that of the gas evacuation duct from the vaporization of LNG from tank trucks, which in a preferable arrangement of the invention is removed from the ship to be liquefied outside it, although it is not discarded that can be liquefied on the ship itself or can be used for the consumption of the propellant engines in the case of gas propulsion.
    [0079]
    [0080] The refueling ship to ships propelled to LNG liquefied natural gas, as well as LNG liquefied natural gas loading station, is completed with the inclusion of essential systems for handling the vessel and the products transported therein
    [0081]
    [0082] - Emergency systems for quick disconnection of the air hoses connecting the ship and the small LNG cargo ship or the ship to refuel.
    [0083] - Emergency systems that interrupt the operation of loading / unloading of LNG in tank trucks in case of abnormality or leakage.
    [0084] - Systems of detection and extinction of fire
    [0085] - LNG accidental discharge management system
    [0086]

    [0097]
    [0098] DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    [0099]
    [0100] In Figures 1 to 3 they represent respectively a profile, plan and cross-sectional view of a ship (1) tanker truck (3) as proposed by the invention, in which said ship has a flat surface that is the deck ( 2), which is accessed well from the bow access (4) and from the stern access (5), which in this case the bow as the stern are indifferent to being able to navigate the boat interchangeably by having propulsion systems (6 ) on both sides and thus be able to increase maneuverability.
    [0101]
    [0102] To facilitate the access of the tank trucks (3) to the deck (2) of the boat, there are bow ramps (7) and stern ramps (8) that facilitate the up and down of the tank trucks (3). .
    [0103]
    [0104] In these figures it can be seen that said ship has nine cargo positions (9) of tank trucks, where the trucks are placed in battery three by three, covering the deck of the ship. In the cross section of the ship, shown in Figure 3, three of the tank trucks (3) aligned with the loading / unloading modules (10) of the tank trucks can be seen.
    [0105]
    [0106] Figure 4 represents a schematic aerial perspective view of a ship (1) like the one of the invention loading or unloading tank trucks (3) on the deck (2) of the vessel. This representation allows to see how a tank truck (3) accesses through the bow ramp (7) to the bow access (4) and how another tank truck (3) is already placed in its loading / unloading station (9) so that the LNG tank truck can be filled from the loading / unloading module (10) or the LNG can be unloaded to refuel another ship. These operations are carried out when the ship approaches the small LNG cargo ship and connects with it, for tanker truck loading operations, or if another ship to refuel in bunkering operations is approached, proceed to the discharge of the cisterns to the ship to refuel.
    [0107] In this same representation and when it comes to LNG loading operations on tank trucks, it can be seen that once the tank trucks (3) are filled with LNG, the ship will go to the port, placing it in such a way that it is the stern ramp (8) which is deployed leaving the tankers in the direction of travel through the stern access (5).
    [0108]
    [0109] It is observed in this same figure 4, that while the loading / unloading stations (9) are nine on the deck of the ship, however the loading modules (10) are arranged in number of twelve and that is due to the reversibility of the ship, which may allow access or exit of the ship from both bow and stern, so that an aligned configuration of the cargo modules must be provided, in a number such that the number of cargo positions plus one is defined. the load modules to be arranged longitudinally aligned with the ship's shaft (1). In this case, since there are three parallel alignments of cargo posts, there will be three more charge modules than the number of cargo posts, as shown in the figure above.
    [0110]
    [0111] Figures 5 and 6 represent schematic plan views of the loading and unloading process of the trucks on the deck of the ship. In figure 6, the flow of empty trucks is observed by arrows entering the ship (1) through the stern access (5) and how they are located, each tank truck in its loading / unloading station (9) to connect to the loading / unloading modules (10). On arrival at the port, the ship (1) faces its bow and the bow access (4) to the port dock, so that the trucks follow a maneuvering flow in the ship (1), that is, if the tankers enter by the bow, it must leave the same one by the stern (5), avoiding with it maneuvers of the tankers in the deck of the ship (2).
    [0112]
    [0113] Figure 7 represents a diagram of the diagram of existing pipes in the ship (1) and how it is connected to the small LNG cargo ship (11) or to the refueling vessel (11 ') through the ship connection module (12) . This same figure shows the twelve load modules (10), each of which will have
    [0114]
    [0115] - an LNG loader / unloader (13) to and from tank trucks (3)
    [0116] - a BOG evaporated natural gas unloader (14) from tank trucks (3), which extracts vaporized LNG
    [0117] - control valves (27), cut-off (31) and safety (28) that ensure a safe filling of the tanks
    [0118] - a system for instrumentation, measurement and control of the LNG loading process in truck tanks (29)
    [0119] - loading hoses and connection / disconnection systems between truck hoses and tanks (30).
    [0120]
    [0121] These last three elements are not shown in detail in the figure but the distribution module (17) of the LNG in the ship, which basically consists of the LNG feed lines (15) and LNG vapor lines (16 ), which are connected to the small LNG vessel (11), or to the ship to refuel (11 ').
    [0122]
    [0123] This figure highlights the discharge of the LNG pumping module (18) that is used in bunkering functions in a refueling to a ship (11 '), only when the option of the ship's pumping module and the connection of the vessel is used BOG evaporated natural gas pumping module (19).
    [0124]
    [0125] A diagram of the loading and unloading module of a tank truck (3) is shown in Figure 8. In this scheme, the loading / unloading zone (20) of the tank truck (3) has been separated from the connection area to the pumping module (21) from the tank trucks (3), in the case of opting for the operation of refueling to ships through the pumping module.
    [0126]
    [0127] In this scheme it can be seen how the vessel of the invention carries a tank carrier in the two operations that can be performed. In the tank loading operation (3), the filling from an LNG cargo ship of the tank trucks (3), which is carried out through the zone (20) of the loading and unloading module, where the line is observed LNG feed (13) and the LNG vapor return line (14).
    [0128]
    [0129] When the ship is in refueling operations, the LNG discharge from the tank (3) is done through the LNG line consisting of the LNG loader / unloader (13) in the area (20), when using the tank pump to transfer, or use the connection to the pumping module (21) when the person in charge of extracting the LNG from the cisterns for transfer to the ship to refuel, is done by means of the pumping equipment of the ship the invention. The vaporized gas connection formed by the evaporator of evaporated natural gas BOG (14) to maintain the pressure in the system in both cases of pumping will be the same. This figure shows the control valve (27), the safety valve (28), the instrumentation system, measurement and control of the process of LNG load in truck tanks (29), shut-off valve (31) and loading / unloading hoses (32) and connection / disconnection systems between truck hoses and tanks (3). A pipe diagram is shown in figure 9 if the pumping module (23) is used to bunkering the ship to be refueled, through the ship's connection module (12). It shows the connection between the loading / unloading stations of the trucks (10) to a collector (22), the liquefied natural gas pumping equipment (23) that aspirates from said collector (22) and some pumped LNG connections that It consists of the LNG pump module (18) and evaporated natural gas consisting of the BOG evaporated natural gas pump module (19) to the ship connection module (12) as shown in Figure 7.
