Definitions
- the invention relates to the field of fluid storage installations comprising a sealed and thermally insulating tank with a membrane.
- the invention relates in particular to installations for the storage and / or transport of liquefied gas at low temperature, such as Liquefied Petroleum Gas (also called LPG) having for example a temperature between -50 ° C and 0 ° C, or Liquefied Natural Gas (LNG) at around -162 ° C at atmospheric pressure.
- LPG Liquefied Petroleum Gas
- LNG Liquefied Natural Gas
- Fluid storage installations are known for example in document WO2016 / 001 142.
- Such a storage installation comprises a load-bearing structure, for example the internal hull of a ship, and a sealed and thermally insulating tank located at the inside of the supporting structure and fixed to it.
- the waterproof and thermally insulating tank has a multilayer structure superimposed in a thickness direction comprising a waterproofing membrane and a thermally insulating barrier disposed between the waterproofing membrane and the support structure.
- the elements of the tank directly in contact with the fluid like the sump structure are subjected to a strong temperature variation which has the consequence of contracting them thermally.
- the sump structure is fixed to the supporting structure which is not in contact with the cryogenic fluid.
- the fixing means making it possible to fix the sump structure to the support structure could therefore be subjected to high mechanical stresses which can accelerate the fatigue of the materials and limit the operating time of the tank.
- An idea underlying the invention is to improve the fixing between the sump structure and the supporting structure to increase its service life and reliability.
- the invention provides a fluid storage installation, the storage installation comprising a support structure and a sealed and thermally insulating tank, the tank comprising at least one bottom wall fixed to the support structure, in the bottom wall of which has a multilayer structure superimposed in a thickness direction including at least one waterproofing membrane and at least one thermal insulation barrier disposed between the waterproofing membrane and the support structure, in which the bottom wall comprises a sump structure locally interrupting the waterproofing membrane of the bottom wall, the sump structure comprising a rigid container having a side wall, the container being arranged through the thickness of the wall bottom, and the sump structure comprising at least one fixing means designed to fix the rigid container to the carrying structure at a fixing point of the side wall,
- the at least one fixing means is configured to allow relative movement of the side wall of the container relative to the support structure in a transverse direction perpendicular to the side wall at the point of fixing of the container, the relative movement being greater than 1 mm, for example between 1 and 5 mm.
- attachment point of the side wall refers, according to all the embodiments, to the location of attachment of the attachment means to the sump structure, at the level of the side wall of the latter.
- the at least one fixing means makes it possible to fix the sump structure to the support structure while allowing the side wall of the container of the sump structure to be able to move relatively relative to the support structure in the transverse direction.
- the sump structure can thus contract thermally while remaining fixed to the supporting structure and preventing the at least one fixing means from being subjected to excessive mechanical stresses.
- such a storage installation may include one or more of the following characteristics.
- the at least one fixing means comprises a first portion fixed, preferably welded, to the support structure and a second portion fixed, preferably welded to the side wall of the container.
- the at least one fixing means is fixed directly, preferably welded directly, to the support structure. According to one embodiment, the at least one fixing means is fixed directly, preferably welded directly, to the side wall of the container.
- the support structure is made of a metallic material.
- the support structure is a portion of the hull of a floating structure.
- the at least one fixing means is located between the sealing membrane and the support structure in the thickness direction.
- the sump structure comprises a fixing wing fixed in a sealed manner, that is to say forming a closed surface that does not allow the fluid, for example welded, to pass to the sealing membrane.
- the at least one fixing means is at least partially located under the fixing wing in the thickness direction.
- the waterproofing membrane is a secondary waterproofing membrane
- the thermally insulating barrier is a secondary thermally insulating barrier
- the fixing wing is a second fixing wing
- the bottom wall comprises a primary thermally insulating barrier located on the secondary sealing membrane and also comprises a primary sealing membrane located on the primary thermally insulating barrier
- the sump structure comprises a first fixing wing fixed in a sealed manner, this is that is to say forming a closed surface which does not allow the fluid, for example welded, to pass to the primary sealing membrane.
- the container is a second container
