Definitions
- This disclosure relates to the field of cryogenic fluid transfer installations.
- the disclosure relates to a rotating connection device for cryogenic fluid conduits, capable of circulating at temperatures between -180 degrees and -253 degrees.
- Such a device may, for example, be used in the context of long-distance transport between a fixed unit and a mobile unit, such as at sea or in desert areas, of cryogenic fluid presenting risks of explosion or pollution in the event of contact with outside air.
- Cryogenic fluid transfer installations such as loading arms, are for example detailed in document WO9815772.
- Such installations also comprise, in a conventional manner, a rotating connection device for cryogenic fluid conduits comprising a bearing as well as a sealing arrangement comprising in particular a sealing joint impermeable to the cryogenic fluid or an impermeable sealing joint making it possible to protect the installation from possible climatic conditions.
- a disadvantage of current installations is that, in the event of failure of the means provided to ensure the proper transfer of the cryogenic fluid and in particular in the event of failure of the means to ensure the sealing of such an installation, the cryogenic fluid is directly able to escape from the conduits and therefore end up in the external environment, which is not satisfactory due to the risks of explosion on contact with the external air.
- One aspect of the disclosure is to at least partially overcome the disadvantages of prior art techniques.
- the disclosure relates to a device for rotating connection of cryogenic fluid conduits, comprising a first conduit part forming a female joint part and a second conduit part forming a male joint part, connected so as to delimit a conduit for circulation of the cryogenic fluid and to form a chamber for heating the cryogenic fluid between the first and second conduit parts, said conduit for circulation of the cryogenic fluid being thermally insulated, said first conduit part having a first external annular flange and said second conduit part having a second external annular flange, between which is clamped a bearing comprising a radially external ring detachably connected to one of the two external annular flanges and a radially internal ring detachably connected to the other of the two external annular flanges, so as to guide in rotation the assembly formed by said first conduit part and said second conduit part, said rotating connection device further comprising: a first seal impermeable to the cryogenic fluid, arranged at a junction interface between said first conduit part and said second conduit part opening

- the second seal thus provides safety in the event of failure of the first seal and/or the third seal.
- the first seal ensures a seal against the cryogenic fluid.

- the second seal ensures a seal to prevent the cryogenic fluid from leaking to the outside.
- said cryogenic fluid circulation conduit is thermally insulated so as to minimize heat inputs into said cryogenic fluid circulating in said circulation conduit.

- said cryogenic fluid heating chamber has a U-shape winding between the first conduit piece and the second conduit piece and defining a thermally insulated annular intermediate space, so as to minimize heat inputs into said cryogenic fluid circulating in said circulation conduit.
- this makes it possible to thermally isolate said cryogenic fluid circulation pipe so as to minimize heat inputs into said cryogenic fluid circulating in said circulation pipe.
