Description

Antecedentes da InvençãoBackground of the Invention

[001] A presente invenção refere-se a um tanque criogênico para uso em vasos onde o tanque é montado entre duas fundações horizontais ou plataformas.[001] The present invention relates to a cryogenic tank for use in vessels where the tank is mounted between two horizontal foundations or platforms.

[002] Particularmente no que diz respeito a tanques para gás ou líquido criogênico onde os tanques estão em movimento, tais como unidades de produção ou unidades de transporte em vasos, existem exigências estritas em relação a vazamentos. Tais vazamentos ocorrem se o tanque é submetido a cargas dinâmicas produzindo tensões que novamente podem levar à formação de rachaduras no material do tanque. As cargas dinâmicas podem ocorrer devido a cargas diretas no tanque ou devido a deflexões dinâmicas das estruturas de suporte.[002] Particularly with regard to tanks for gas or cryogenic liquid where the tanks are in motion, such as production units or vessel transport units, there are strict requirements regarding leakage. Such leaks occur if the tank is subjected to dynamic loads producing stresses that again can lead to the formation of cracks in the tank material. Dynamic loads can occur due to direct loads on the tank or due to dynamic deflections of the support structures.

[003] Tanques criogênicos são também submetidos a deflexões significativas devidas a grandes variações de temperatura. Isto deve ser possível de manipular sem a introdução de tensões muito altas no tanque. É também importante se explorar o volume disponível a bordo de um vaso da melhor maneira possível e se ter uma partição apropriada do tanque no que diz respeito à redundância e à manutenção e, desta forma, o tanque deve ser projetado tendo-se isto em mente. Em alguns casos é também importante que a área acima do tanque possa ser explorada, isto é, deve ser possível a construção do tanque, por exemplo, sob uma plataforma com equipamento.[003] Cryogenic tanks are also subjected to significant deflections due to large temperature variations. This must be possible to handle without introducing very high voltages into the tank. It is also important to exploit the volume available on board a vessel as best as possible and to have a proper partition of the tank with regard to redundancy and maintenance and therefore the tank should be designed with this in mind . In some cases it is also important that the area above the tank can be explored, ie it must be possible to build the tank, for example, under a platform with equipment.

AntecedentesBackground

[004] Existem vários tipos de tanques criogênicos com diferentes desenhos e suportes incluindo alguns que satisfazem algumas das condições descritas acima. Do estado da técnica existente mencionamos os textos da patente US 347 622, para uma área algo diferente, e US 6 082 676 para um veículo de lançamento ou espacial, onde é utilizada uma saia como fundação para o tanque.[004] There are several types of cryogenic tanks with different designs and supports including some that satisfy some of the conditions described above. From the state of the existing art we mention the texts of patent US 347 622, for a somewhat different area, and US 6 082 676 for a launch or space vehicle, where a skirt is used as a foundation for the tank.

Sumário da InvençãoInvention Summary

[005] O suporte do tanque de acordo com a presente invenção, portanto, cumpre com todas as condições descritas acima. Isto é obtido de acordo com a definição do tanque tal como descrito nas características das reivindicações.[005] The tank support according to the present invention, therefore, complies with all the conditions described above. This is achieved in accordance with the definition of the tank as described in the features of the claims.

[006] Com o tanque de acordo com a invenção, o suporte é obtido de tal forma que produz cargas dinâmicas pequenas. Desta forma, uma maneira eficiente de recepção de deflexões na fundação e deflexões devidas a variações de temperatura, é alcançada. Além disto, uma exploração excelente do volume disponível com a partição apropriada do tanque é alcançada. A realização também possibilita a colocação do equipamento sobre uma plataforma acima do tanque.[006] With the tank according to the invention, the support is obtained in such a way that it produces small dynamic loads. In this way, an efficient way of receiving deflections in the foundation and deflections due to temperature variations is achieved. Furthermore, an excellent exploitation of the available volume with proper tank partition is achieved. The realization also makes it possible to place the equipment on a platform above the tank.

Breve Descrição dos DesenhosBrief Description of Drawings

[007] No desenho a única figura mostra uma seção vertical através de um tanque criogênico de acordo com a invenção.Descrição Detalhada de uma Realização Ilustrativa[007] In the drawing the only figure shows a vertical section through a cryogenic tank according to the invention.Detailed Description of an Illustrative Embodiment

[008] O tanque de acordo com a invenção compreender um tanque posicionado verticalmente com uma parte central cilíndrica (1). O tanque apresenta uma placa superior cuja parte externa (4) é horizontal, enquanto que a parte central (5) é preferivelmente de formato cônico.[008] The tank according to the invention comprise a vertically positioned tank with a cylindrical central part (1). The tank has an upper plate whose outer part (4) is horizontal, while the central part (5) is preferably conical in shape.

[009] A parte interna radial da parte externa horizontal (4) da placa superior recebe uma saia cilíndrica superior (7) posicionada verticalmente, a dita segunda extremidade da saia é fixada à fundação superior (8) ou plataforma. A saia cilíndrica superior (7) apresenta um diâmetro menor que o diâmetro da parte cilíndrica (1).[009] The radial inner part of the horizontal outer part (4) of the top plate receives an upper cylindrical skirt (7) positioned vertically, said second end of the skirt is fixed to the upper foundation (8) or platform. The upper cylindrical skirt (7) has a diameter smaller than the diameter of the cylindrical part (1).

[010] O tanque compreende ainda um fundo esférico (2) que é conectado a uma saia cilíndrica (3) na transição (6) entre a parte cilíndrica (1) do tanque ao fundo esférico (2).[010] The tank further comprises a spherical bottom (2) which is connected to a cylindrical skirt (3) at the transition (6) between the cylindrical part (1) of the tank to the spherical bottom (2).

[011] A saia cilíndrica (3) suporta o tanque contra uma fundação inferior (9) ou plataforma.[011] The cylindrical skirt (3) supports the tank against a lower foundation (9) or platform.

[012] Uma vez que a parte externa (4) da placa superior do tanque é horizontal, a dita parte constituirá um mecanismo flexível na direção vertical do tanque, uma vez que a parte externa horizontal (4) da placa superior será flexível para movimentos verticais. Isto receberá com eficiência deflexões verticais devidas a alterações de temperatura. Ao mesmo tempo este mecanismo irá transmitir eficientemente forças laterais entre a fundação superior (8) e o tanque e entre a fundação inferior (9) e o tanque.Além disto, isto possibilita a colocação do tanque sob uma fundação superior (8).[012] Since the outer part (4) of the tank top plate is horizontal, said part will constitute a flexible mechanism in the vertical direction of the tank, since the horizontal outer part (4) of the top plate will be flexible for movements vertical. This will efficiently receive vertical deflections due to temperature changes. At the same time this mechanism will efficiently transmit lateral forces between the upper foundation (8) and the tank and between the lower foundation (9) and the tank. In addition, this makes it possible to place the tank under an upper foundation (8).

[013] O tanque criogênico de acordo com a invenção combina recepção de carga eficiente a partir do conteúdo do tanque em exploração eficiente do volume disponível nos locais em que o volume deve compreender uma pluralidade de tanques.[013] The cryogenic tank according to the invention combines efficient cargo reception from the contents of the tank in efficient exploration of the available volume in places where the volume must comprise a plurality of tanks.

[014] A saia (3) pode ser adequadamente de material inoxidável de maneira a reduzir a condução de calor entra o tanque e a fundação (9) onde a saia (3) está apoiada.[014] The skirt (3) can be suitably made of stainless material in order to reduce heat conduction between the tank and the foundation (9) where the skirt (3) is supported.
