Description

Foreliggende oppfinnelse angår en kryogenisk tank for fartøy, ifølge kravinnledningen. The present invention relates to a cryogenic tank for vessels, according to the preamble.

Det er svært strenge krav til kryogeniske tanker med hensyn til lekkasjer. Slike lekkasjer vil kunne oppstå dersom tanken er utsatt for dynamiske belastninger som gir spenninger som fører til sprekkvekst i materialet. Dynamiske belastninger kan komme som en følge av direkte belastninger på tanken eller som en følge av dynamiske defleksjoner av supporterende struktur. Kryogeniske tanker utsettes også for vesentlige defleksjoner på grunn av store temperaturendringer, dette må kunne håndteres uten å introdusere for høye spenninger i tanken. Det er også viktig å utnytte tilgjengelig volum best mulig og ha en fornuftig tankinndeling med hensyn på redundans og vedlikehold, og tanken må utformes i henhold til dette. I noen tilfeller er det også viktig at arealet over tanken kan utnyttes, det vi si at tanken må kunne bygges inn under f.eks. et dekk med utstyr. There are very strict requirements for cryogenic tanks with regard to leaks. Such leaks could occur if the tank is exposed to dynamic loads that produce stresses that lead to crack growth in the material. Dynamic loads can come as a result of direct loads on the tank or as a result of dynamic deflections of the supporting structure. Cryogenic tanks are also exposed to significant deflections due to large temperature changes, this must be able to be handled without introducing excessive stresses in the tank. It is also important to utilize the available volume as best as possible and to have a sensible tank division with regard to redundancy and maintenance, and the tank must be designed accordingly. In some cases, it is also important that the area above the tank can be utilized, meaning that the tank must be able to be built in under e.g. a deck with equipment.

Det eksisterer ulike typer kryogeniske tanker med ulik utforming og opplagring, og som løser de fleste begrensninger og ulemper beskrevet ovenfor. There are different types of cryogenic tanks with different designs and storage, and which solve most of the limitations and disadvantages described above.

Med tanken ifølge foreliggende oppfinnelse oppnås de foran beskrevne målsetninger, med den i kravene definerte trekk. With the tank according to the present invention, the objectives described above are achieved, with the feature defined in the requirements.

Tegningen viser på figur 1 et vertikalsnitt gjennom en tank ifølge oppfinnelsen, og figur 2 viser et detaljert utsnitt av forbindelsen mellom tankens sylindriske del og tankens plane bunn. The drawing shows in Figure 1 a vertical section through a tank according to the invention, and Figure 2 shows a detailed section of the connection between the tank's cylindrical part and the tank's flat bottom.

Med tanken ifølge oppfinnelsen oppnås en opplagring som gir små dynamiske spenninger i tanken, det oppnås en effektiv måte å ta opp defleksjoner i fundamentet og defleksjoner fra temperaturendringer. Det oppnås videre en god utnyttelse av tilgjengelig volum med fornuftig tankinndeling, og utformingen ifølge oppfinnelsen gir mulighet til å plassere utstyr på et dekk over tanken. With the tank according to the invention, a storage is achieved that produces small dynamic stresses in the tank, an effective way of absorbing deflections in the foundation and deflections from temperature changes is achieved. Good utilization of the available volume is also achieved with sensible tank division, and the design according to the invention provides the opportunity to place equipment on a deck above the tank.

Ifølge oppfinnelsen omfatter tanken en vertikalt stilt sylindrisk vegg 1 med topp 7 og en horisontal bunn 2. Tanken er opplagret med et sylindrisk skjørt 9 mellom tankens topp 7 og et øvre fundament 10. According to the invention, the tank comprises a vertically positioned cylindrical wall 1 with a top 7 and a horizontal bottom 2. The tank is supported by a cylindrical skirt 9 between the top 7 of the tank and an upper foundation 10.

I bunnen er tanken opplagret på lastbærende isolasjon 6 mot et nedre fundament 5. Den lastbærende isolasjonen 6 overfører kun vertikale krefter fra tanken. Horisontale krefter overføres fra tanken via en horisontal ring 3 til et sirkulært eller mangekantet skjørt 4 som igjen overfører de horisontale kreftene til det nedre fundamentet 5. Den horisontale ringen 3 er fleksibel i vertikal retning slik at vertikale krefter fra tanken overføres som jevnt fordelt trykk til den lastbærende isolasjonen 6, mens de horisontale kreftene overføres via den horisontale ringen 3 til det sirkulære skjørtet 4. At the bottom, the tank is stored on load-bearing insulation 6 against a lower foundation 5. The load-bearing insulation 6 only transfers vertical forces from the tank. Horizontal forces are transferred from the tank via a horizontal ring 3 to a circular or polygonal skirt 4 which in turn transfers the horizontal forces to the lower foundation 5. The horizontal ring 3 is flexible in the vertical direction so that vertical forces from the tank are transferred as evenly distributed pressure to the load-bearing insulation 6, while the horizontal forces are transferred via the horizontal ring 3 to the circular skirt 4.

Radialt stilte kneplater 11 kan, hvis nødvendig, plasseres i overgangen mellom tankens sylindriske vegg 1 og tankens horisontale bunn 2. Kneplatene 11 er utformet slik at de gir en myk overføring av krefter fra den sylindriske veggen 1 til den horisontale bunnen 2. Kneplatene 11 er festet mot stivere 12 til den sylindriske veggen 1 og mot stivere 13 til den horisontale bunnen 2. Radially positioned knee plates 11 can, if necessary, be placed in the transition between the tank's cylindrical wall 1 and the tank's horizontal bottom 2. The knee plates 11 are designed so that they provide a smooth transfer of forces from the cylindrical wall 1 to the horizontal bottom 2. The knee plates 11 are attached to struts 12 to the cylindrical wall 1 and to struts 13 to the horizontal bottom 2.

Videre er den horisontale ringen 3 utstyrt med et sirkulært skjørt 14 som vil utgjøre en oppsamlingsbakk for kryogenisk væske som måtte lekke fra tanken. Som ekstra barriere kan det arrangeres et materiallag 15 som tåler kryogenisk væske, mellom de to isolasjonslagene og som forløper utenfor det øvre isolasjonslaget 6 til et skjørt 8 som vil utgjøre en sekundær oppsamlingsbakk for kryogenisk væske som måtte lekke fra tanken. Furthermore, the horizontal ring 3 is equipped with a circular skirt 14 which will constitute a collection tray for cryogenic liquid that may leak from the tank. As an additional barrier, a material layer 15 that can withstand cryogenic liquid can be arranged between the two insulation layers and which extends outside the upper insulation layer 6 to a skirt 8 which will constitute a secondary collection tray for cryogenic liquid that may leak from the tank.

Den stående kryogeniske tanken ifølge oppfinnelsen, med sylindrisk utforming, kombinerer effektivt lastopptak fra tanken og tankens innhold med effektiv utnyttelse av tilgjengelig volum. The vertical cryogenic tank according to the invention, with a cylindrical design, combines efficient load absorption from the tank and the tank's contents with efficient utilization of the available volume.
