Definitions
- the invention relates to the field of tanks with sealed and insulating membranes arranged in floating structures, especially for the storage and / or transport of a cold product, in particular a liquefied gas, for example liquefied natural gas (LNG) which contains a high methane content and has a liquid state at about -162 ° C at atmospheric pressure.
- a liquefied gas for example liquefied natural gas (LNG) which contains a high methane content and has a liquid state at about -162 ° C at atmospheric pressure.

- the plane rim 219 of the secondary bowl 216 is supported in a counterbore on the top of the modular blocks 204 forming the secondary insulating barrier where it is fixed.
- the insulating block 230 of relatively thin thickness is preferably made of material with a very high insulating power, for example in aerogels or vacuum insulating panel.
- a relatively rigid block can be installed between the bottom 218 and the bottom 213 to improve the support of the primary bowl 211.
- the secondary waterproof membrane 205 is sealingly bonded to the plane rim 219.
- circulation grooves are provided in the bottom plate 59 of the modular blocks 206, so as to allow the passage of the gaseous phase between the primary space of the tank wall and the primary space 233 of the sump structure.
- FIG. 10 differs from FIG. 9 only by the addition of a frustoconical upper nozzle 58 above the primary bowl 211.
- This nozzle is provided at its base, just above the watertight membrane. primary not shown, inlet ports 61 controlled by non-return valves not shown, which capture in the frustoconical upper nozzle 58 liquid residues at the bottom of the tank.
- the techniques described above for producing a sump structure can be used in different types of tanks, for example an LNG tank in a floating structure such as a LNG tank or other.
- FIG. 11 diagrammatically illustrates the installation of a sump structure, here corresponding to the sump structure 210 of FIG. 9, at the base of a loading / unloading tower 60 in a tank of a LNG carrier, namely at the vertical of the liquid dome of the tank.
- the loading / unloading tower 60 is supported by a support leg 63 bearing on the carrier wall 3 which is the inner bottom wall of the double hull of the ship.
- the loading / unloading tower 60 comprises in particular a main pump 62 and an auxiliary pump 1 of smaller flow than the main pump 62.
- the sump structure 210 is arranged to receive the suction inlet of the auxiliary pump 1.
- the tank walls 65 can be made according to the usual flat multilayer structure, both at the bottom wall 3 and the transverse cofferdam. 64, and the connection to the sump structure 210 is obtained without significantly deflecting the waterproof membranes of their usual planar geometry.
- a cutaway view of a LNG tank 70 shows a sealed and insulated tank 71 of generally prismatic shape mounted in the double hull 72 of the ship.
- the wall of the tank 71 comprises a primary sealed barrier intended to be in contact with the LNG contained in the tank, a barrier secondary sealing arranged between the primary sealed barrier and the double hull 72 of the ship, and two insulating barriers respectively arranged between the primary watertight barrier and the secondary watertight barrier and between the secondary watertight barrier and the double hull 72.
- loading / unloading lines 73 arranged on the upper deck of the ship can be connected, by means of appropriate connectors, to a marine or port terminal to transfer a cargo of LNG from or to the tank 71.
- FIG. 12 represents an example of a marine terminal comprising a loading and unloading station 75, an underwater pipe 76 and an onshore installation 77.
- the loading and unloading station 75 is a fixed off-shore installation comprising an arm mobile 74 and a tower 78 which supports the movable arm 74.
- the movable arm 74 carries a bundle of insulated flexible pipes 79 that can connect to the loading / unloading pipes 73.
- the movable arm 74 can be adapted to all gauges of LNG carriers .
- a connection pipe (not shown) extends inside the tower 78.
- the loading and unloading station 75 enables the loading and unloading of the LNG tank 70 from or to the shore facility 77.
- the underwater line 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the onshore installation 77 over a large distance, for example 5 km, which makes it possible to keep the tanker vessel 70 at great distance from the coast during the loading and unloading operations.
- pumps on board the ship 70 and / or pumps equipping the shore installation 77 and / or pumps equipping the loading and unloading station 75 are used.
- the unloading of the tank it is possible to use in particular the auxiliary pump 1 and / or the main pump 62 arranged in the tank.
