Definitions
- the invention relates to the field of sealed and thermally insulating tanks for the storage and / or transport of a fluid, such as liquefied gas and relates more particularly to a corner structure for such a tank.
- Sealed and thermally insulating tanks are used in particular for the storage of liquefied natural gas (LNG), which is stored, at atmospheric pressure, at around -163 ° C or for the storage of liquefied petroleum gas (LPG).
- LNG liquefied natural gas
- LPG liquefied petroleum gas
- These tanks can be installed on the ground or on a floating structure. In the case of a floating structure, the tank can be intended for the transport of liquefied gas or to receive liquefied gas serving as fuel for the propulsion of the floating structure.
- the corner structure comprises a movable corner piece which consists of a primary angle and a secondary angle separated from each other and respectively welded to the primary sealing membranes of the two adjacent walls and to the membranes. secondary sealing of the two adjacent walls.
- the movable corner piece is slidably mounted on an anchoring device which has two legs arranged perpendicular to each other and fixed to a base which is anchored to the supporting structure of each of the two adjacent walls.
- the two tabs each have openings and connecting tabs formed between the openings, the connecting tabs of each of the two tabs passing through the openings of the other tab. This aims to limit the stress concentrations in the corner structure.
- the corner structure In order to thermally insulate the corner structure, it has a first insulating panel which is disposed against the supporting structure of the first wall and fills a space delimited by the internal portion of the first leg and the external portion of the second paw.
- the corner structure has a second insulating panel which is arranged against the supporting structure of the second wall and fills a space delimited by the internal portion of the second tab and the external portion of the first tab. Insulating elements are also positioned in the space provided between the external portions of the first and second legs. A triangular space is left unoccupied between the movable corner piece and the internal portions of the two legs.
- Another triangular space is also unoccupied, on the other side of the intersection between the two legs, in the zone delimited by the external portion of the two legs.
- the aforementioned empty triangular spaces make it possible to increase the freedom of movement of the two legs so as to further limit the concentrations of stresses in the corner structure.
- An idea underlying the invention is to provide a corner structure of the aforementioned type in which the thermal insulation performance is increased.
- the invention provides a corner structure for a sealed and thermally insulating tank for storing a fluid comprising a first wall and a second wall which each have successively, in a thickness direction of said wall , from the outside towards the inside of the tank, a support structure, a thermally insulating barrier retained at the support structure and a sealing membrane supported by said thermally insulating barrier; said corner structure being intended to be arranged at an angle between the first wall and the second wall, the corner structure comprising: a first angle comprising a first wing and a second wing which extend respectively in a first plane intended to be positioned parallel to the first wall and along a second plane intended to be positioned parallel to the second wall, the first wing and the second wing being respectively intended to be welded in a sealed manner to the sealing membrane of the first wall and to the sealing membrane of the second wall; said first angle being anchored to an anchoring device intended to be fixed to the support structure of the first and of the second walls; the anchoring device comprising a first leg
- the corner structure further comprising a first insulating panel which is arranged in a first space delimited by the internal portion of the first leg and the external portion of the second leg and a first lateral element of insulating lining which is compressed between the first insulating panel and the outer portion of the second leg.
- the first lateral element of the insulating lining being compressed, it is able to relax to compensate for the thermal contraction of the first insulating panel. Consequently, the first lateral element of the insulating lining makes it possible to ensure continuity of the thermal insulation and to limit the phenomena of convection inside the corner structure.
- such a corner structure may include one or more of the following characteristics.
- the first plane and the second plane are perpendicular to each other.
- the first plane and the second plane form an angle of 135 °.
- the corner structure further comprises a second insulating panel which is arranged in a second space delimited by the internal portion of the second leg and the external portion of the first leg and a second lateral element of insulating lining. which is compressed between the second insulating panel and the outer portion of the first tab.
- the first and / or the second insulating panels comprise a layer of polymer foam chosen from polyurethane foam, polyethylene foam and polyvinyl chloride foam.
- the layer of polymeric foam of the first and / or of the second insulating panels is reinforced with fibers. This makes it possible in particular to limit the thermal contraction of said insulating panel.
- the fibers are glass fibers.
- the layer of polymeric foam of the first and / or of the second insulating panels is devoid of fibers.
- the insulating panel (s) is thus less expensive.
- the thermal contraction of said insulating panel can at least partly be compensated by the first or the second lateral element of insulating lining.
- the layer of insulating polymer foam of the first and / or of the second insulating panels has a density of between 90 and 240 kg / m 3 .
- the first and / or the second lateral elements of the insulating lining have a density of less than 90 kg / m 3 , and preferably between 20 and 50 kg / m 3 .
- Such a material is particularly easy to compress.
- the first and / or the second lateral elements of the insulating lining comprise a layer made of a material chosen from glass wool, rock wool, polyester wadding, polyurethane, melamine, polyethylene foams , polypropylene or silicone.
- the first lateral element of insulating lining comprises a plurality of layers made of glass wool and separated from each other by dividers extending parallel to the foreground. This limits the convection inside the glass wool.
- the second lateral insulating lining element comprises a plurality of layers made of glass wool and separated from each other by dividers extending parallel to the second plane. This limits the convection inside the glass wool.
- the separators are made of kraft paper.
