- This end piece is provided at its base, just above the primary waterproof membrane not shown, with inlet holes 61 controlled by non-return valves not shown, which make it possible to capture, in the frusto-conical upper end 58, the residues of liquid present 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 an LNG tanker or other.
- the figure 11 schematically illustrates the installation of a sump structure, corresponding here to the sump structure 210 of the figure 9 , at the base of a loading / unloading tower 60 in an LNG tank, namely vertical to the liquid dome of the tank.
- the loading / unloading tower 60 is supported by a support leg 63 bearing on the load-bearing wall 3 which is the internal 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 rate than the main pump 62.
- the sump structure 210 is arranged to receive the suction input of the auxiliary pump 1.
- the tank walls 65 can be produced according to the usual planar multilayer structure, both at the bottom wall 3 and at the transverse cofferdam 64, and the connection to the sump structure 210 is obtained without significantly deviating the waterproof membranes from their usual plane geometry.
- a cutaway view of an LNG tanker 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 includes a primary waterproof barrier intended to be in contact with the LNG contained in the tank, a barrier secondary watertight arranged between the primary watertight barrier and the double hull 72 of the ship, and two insulating barriers arranged respectively 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 maritime or port terminal for transferring a cargo of LNG from or to the tank 71.
- the figure 12 represents an example of a maritime terminal comprising a loading and unloading station 75, an underwater pipe 76 and a shore installation 77.
- the loading and unloading station 75 is a fixed offshore installation comprising a movable arm 74 and a tower 78 which supports the movable arm 74.
- the movable arm 74 carries a bundle of insulated flexible pipes 79 which can be connected to the loading / unloading pipes 73.
- the movable arm 74 can be adjusted to suit all sizes of LNG carriers.
- a connection pipe, not shown, extends inside the tower 78.
- the loading and unloading station 75 allows the loading and unloading of the LNG carrier 70 from or to the onshore installation 77.
- This comprises liquefied gas storage tanks 80 and connecting pipes 81 connected by the subsea pipe 76 to the loading or unloading station 75.
- the subsea pipe 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the shore installation 77 over a long distance, for example 5 km, which makes it possible to keep the LNG carrier 70 at a great distance from the coast during the loading and unloading operations.
- pumps on board the ship 70 and / or pumps fitted to the shore installation 77 and / or pumps fitted to the loading and unloading station 75 are used. unloading the tank, one can use in particular the auxiliary pump 1 and / or the main pump 62 arranged in the tank.
