- This second mast 112 has a larger diameter than the first mast 113 and the third mast 114, both associated with a pumping member.
- the second mast 112 is closed by a closing cover 1110.
- This closing cover 1110 is removable and can be removed from the second mast 112 to allow the insertion of an emergency pump lowered to the bottom of the tank.
- the pumps 103 of the pumping members 107 are fixed to the second longitudinal end 1011 of their respective mast 101.
- the pumps 103 are cylindrical and are fixed to the second longitudinal end 1011 of the first mast 113 and the third mast 114.
- the base 108 is a mechanically welded assembly consisting of side walls 1081 which extend between the masts 101 of the tower 100.
- the base 108 cooperates with each of the masts 101 of the tower 100, by means of a device 'hook 1084 composed of straps 1082 each surrounding a mast 101.
- two straps 1082 are arranged each mast 101, between the trellis structure 1012 and an upper end of the pump 103.
- the straps 1082 are connected to the lateral faces 1081 base 108 by struts 1083, of oblique orientation relative to the lateral faces 1081.
- the struts 1083 extend between the two straps 1082 of each mast 101 and a plate 118 of the base 108.
- the base 108 also cooperates with removable fixing means allowing the mounting and dismounting of the pumps 103 relative to the mast 101.
- the removable fixing means include two types of hanging collars 1085.
- the first type of hanging collars 1085 corresponds to the 1085 hanging collars arranged above the pump 103. These hanging collars 1085 are fixed to the struts 1083 of the base 108 through brackets 1086.
- the second type of hanging collars 1085 corresponds to the hanging collars 1085 arranged below the pump 103.
- These attachment collars 1058 are fixed to the lateral faces 1081 of the base 108 through brackets 1086.
- the straps 1082 fixed on the first mast 113 and / or on the third mast 114 and / or on the second mast 112 constitute a point of attachment of the base 108 on the first mast 113 and / or on the third mast 114 and / or the second mast 112.
- the attachment point of the first mast 113 and / or of the third mast 114 is vertically above the attachment point of the second mast 112, this distance is represented by the reference dl in FIG. 5.
- the pumps 103 are removably mounted on the masts 101, by means of the hanging collars 1085, the latter being removable.
- the pumps 103 can thus be mounted or removed from the first mast 113 and / or the third mast 114 by tilting.
- the second mast 112 of the tower 100 includes a receiving seat 1087 of an emergency pump.
- the tower 100 is composed of two masts 101 carrying a pumping member and a second mast 112 configured to receive a backup pump.
- FIG. 6 represents a sectional view of the mast 101 carrying at its second longitudinal end the pump 103 of the pumping member.
- the mast 101 houses the tube 104 allowing the delivery of the liquefied gas 10 along the mast 101 to be discharged out of the tank.
- This mast 101 also houses the drive shaft 106 connecting the motor to the pump 103, such a drive shaft 106 being here disposed inside the tube 104, for example being co-axial with the latter.
- the mast 101 is mechanically connected to the base by straps 1082 which surround the external diameter of the mast 101.
- the pump 103 is secured to one end of the tube 104 and it is carried by hanging collars 1085 which encircle flanges of pump 103.
- a first attachment collar 1082 is disposed in abutment against an upper flange of the pump 103, and mechanically connected to the base by the bracket 1086.
- a second attachment collar 1085 is disposed in abutment against a lower flange of the pump 103, and mechanically connected to the base by the bracket 1086.
- the LNG is pumped by a suction mouth 116 of the pump 103 and set in motion by a propeller 117 driven in rotation by the drive shaft 106 .
- FIG. 6 also illustrates an exemplary embodiment of the means 115 for modifying the temperature of the mast 101.
- these are orifices 119 which pass through the thickness of the tube 104, so that the LNG in the liquid state is projected against the internal face 120 of the mast 101. It is thus possible to ensure consistency of temperatures and expansion between the tube 104 and its mast 101, when these two parts are mechanically linked to each other .
- the invention thus achieves the goal which it had set itself by allowing intervention on one of the components of the pumping member, in particular the motor, without imposing the implementation of all the steps necessary for emptying and placing an LNG tank under a healthy atmosphere.
- the invention cannot however be limited to the means and configurations exclusively described and illustrated, and also applies to all equivalent means or configurations and to any combination of such means or configurations.
- it goes without saying that it applies to any shape and / or dimension of the loading and / or unloading tower, whether it comprises one or more masts.
