Description

TEKNISK OMRÅDE TECHNICAL AREA

Den foreliggende oppfinnelsen angår et uavhengig tanksystem for lagring av flytende gass i et fartøy. The present invention relates to an independent tank system for storing liquefied gas in a vessel.

BAKGRUNN BACKGROUND

Den internasjonale maritime organisasjonen IMO sin kode IGC (International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk) inneholder en definisjon av såkalte uavhengige LNG-tanker. Uavhengig i denne betydningen betyr at tanken er selvstøttende og uavhengig av skroget til fartøyet. Disse uavhengige tankene kan klassifiseres i tre typer, A, B og C, hvor type A krever en full sekundær barriere, type B krever en delvis sekundær barriere og type C har ikke noe krav for en sekundær barriere. De ulike sikkerhetsfilosofiene som anvendes for de tre ulike systemene nødvendiggjør ulik designkrav for hvert system. The international maritime organization IMO's code IGC (International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk) contains a definition of so-called independent LNG tanks. Independent in this sense means that the tank is self-supporting and independent of the hull of the vessel. These independent tanks can be classified into three types, A, B and C, where type A requires a full secondary barrier, type B requires a partial secondary barrier and type C has no requirement for a secondary barrier. The different security philosophies used for the three different systems necessitate different design requirements for each system.

Det er to kjente tanksystemer for lagring av LNG (Liquefied Natural Gas) som er i bruk i dag, og som følger prinsippene til det uavhengige tanksystemet av type A og B nevnt ovenfor. Det første er Moss sin sfæriske tank, og den andre er IHI selvstøttende prismatiske LNG-tank. There are two known tank systems for storing LNG (Liquefied Natural Gas) that are in use today, and which follow the principles of the independent tank system of type A and B mentioned above. The first is Moss's spherical tank, and the second is the IHI self-supporting prismatic LNG tank.

Det er flere tekniske utfordringer involvert i tanksystemet for lagring av flytende gass. Tanken kan være kryogen, for LNG betyr det at en temperatur på -163°, som betyr at tanken må være isolert for å minimere avbrenning (eng: boil off) og for å hindre skipsskroget fra å bli eksponert for farlige temperaturer. Den lavere temperaturen vil også krympe LNG-tankene som betyr at all støtte, dvs. kobling til skip, må ha en fleksibel natur for ikke å overbelaste tanken eller fundamentet til denne. Et lekkasjebeskyttelsessystem må videre være på plass for å beskytte skipsskroget fra en mulig lekkasje. Sistnevnte sikres ved å tilpasse seg IMO-koden for uavhengige LNG-tanker av type A eller B ved å anvende avanserte designberegninger, høye sikkerhetsfaktorer for å inkludere en full eller delvis sekundær barriere. Tanken må videre motstå treghetskrefter fra den flytende gassen forårsaket av fartøybevegelser på grunn av grov sjø, og spesielt på grunn av skvulping (eng: sloshing) (dvs. påvirkninger på innsiden av tanken fra den flytende gassen i bevegelse). There are several technical challenges involved in the tank system for storing liquefied gas. The tank can be cryogenic, for LNG that means a temperature of -163°, which means that the tank must be insulated to minimize burn-off (eng: boil off) and to prevent the ship's hull from being exposed to dangerous temperatures. The lower temperature will also shrink the LNG tanks, which means that all support, i.e. the connection to the ship, must be of a flexible nature so as not to overload the tank or its foundation. A leak protection system must also be in place to protect the ship's hull from a possible leak. The latter is ensured by adapting to the IMO code for independent LNG tanks of type A or B by applying advanced design calculations, high safety factors to include a full or partial secondary barrier. The tank must also resist inertial forces from the liquid gas caused by vessel movements due to rough seas, and especially due to sloshing (ie impacts on the inside of the tank from the liquid gas in motion).

US 4000711 viser en lagringstank for flytende gass som er støttet i skroget til et skip ved hjelp av et flertall klosser festet til og plassert med mellomrom periferisk rundt tanken. US 4000711 shows a liquefied gas storage tank supported in the hull of a ship by means of a plurality of blocks attached to and spaced circumferentially around the tank.

US 3905508 viser et flertrinns støttesystem mellom et indre og et ytre skrog hos en kryogenisk fluidtank. US 3905508 shows a multi-stage support system between an inner and an outer hull of a cryogenic fluid tank.

Formålet med oppfinnelsen er å tilveiebringe et uavhengig tanksystem for lagring av flytende gass i et flytende fartøy, hvor det midtre tankorganet er sylindrisk med det formål å forbedre den totale lagringskapasiteten mens den totale høyden til tanken holdes relativt lav. Videre må alle tekniske krav nevnt ovenfor være oppfylt. The purpose of the invention is to provide an independent tank system for storing liquefied gas in a floating vessel, where the central tank body is cylindrical with the aim of improving the total storage capacity while the total height of the tank is kept relatively low. Furthermore, all technical requirements mentioned above must be met.

Alternativt kan det første tankorganet være formet som en sfærisk kappe (eng: spherical cap). I enda en alternativ utførelsesform kan det første tankorganet 1 være torisfærisk eller torikonisk. I disse alternative utførelsesformene vil radius RI' indikerer radiusen til den sirkulære nedre kanten av det første tankorganet (i tilfelle det første tankorganet 1 er en hemisfære vil RI være lik RI'). The first tank member 1 is the upper tank member or top tank member of the tank device. The first tank member is substantially hemispherical with radius RI as indicated in fig. 1. Alternatively, the first tank member can be shaped like a spherical cap. In yet another alternative embodiment, the first tank member 1 can be torispherical or torisconical. In these alternative embodiments, the radius RI' will indicate the radius of the circular lower edge of the first tank member (in case the first tank member 1 is a hemisphere, RI will be equal to RI').

Det andre tankorganet 2 er sylindrisk, med en radius R2 tilsvarende radiusen RI eller RI' til den sirkulære nedre kanten til det første tankorganet 1. Den øvre sirkulære kanten til det andre tankorganet 2 er koblet til den nedre sirkulære kanten hos det første tankorganet 1, for dermed å definere en sirkulær første forbindelse 12. The second tank member 2 is cylindrical, with a radius R2 corresponding to the radius RI or RI' of the circular lower edge of the first tank member 1. The upper circular edge of the second tank member 2 is connected to the lower circular edge of the first tank member 1, thereby defining a circular first connection 12.

Det tredje tankorganet 3 er det nedre tankorganet eller bunntankorganet hos anordningen hos tankanordningen, med en radius R3 tilsvarende radiusen R2 til det andre tankorganet 2. En øvre sirkulær kant av det tredje tankorganet 3 er koblet til en nedre sirkulær kant hos det andre tankorganet 2, og definerer med dette en sirkulær andre forbindelse 23.1 den foreliggende oppfinnelsen er det tredje tankorganet 3 torikonisk, dvs. har en konisk nedre bunnflate vendt mot skroget til fartøyet. En vinkel a mellom den koniske bunnoverflaten og det horisontale planet er indikert i fig. 1. Fortrinnsvis er vinkelen a > 5°. En for stor vinkel a er imidlertid en ulempe siden dette vil redusere lagringskapasiteten til tankanordningen. De første, andre og tredje tankorganene er i den foreliggende oppfinnelsen laget av en 9 % sveiset nikkelstålkonstruksjon. Alternativt kan materialet i tankorganene være andre typer nikkelstål, rustfritt stål, etc. Videre kan materialet til tankorganene være aluminium. The third tank member 3 is the lower tank member or bottom tank member of the device of the tank device, with a radius R3 corresponding to the radius R2 of the second tank member 2. An upper circular edge of the third tank member 3 is connected to a lower circular edge of the second tank member 2, and thereby defines a circular second connection 23.1 the present invention, the third tank member 3 is toriconic, i.e. has a conical lower bottom surface facing the hull of the vessel. An angle a between the conical bottom surface and the horizontal plane is indicated in fig. 1. Preferably, the angle a > 5°. However, an angle a that is too large is a disadvantage since this will reduce the storage capacity of the tank device. The first, second and third tank members are in the present invention made of a 9% welded nickel steel construction. Alternatively, the material of the tank members can be other types of nickel steel, stainless steel, etc. Furthermore, the material of the tank members can be aluminium.

Det første tankorganet og det andre tankorganet er begge uavstivede strukturer. Dette forenkler konstruksjonen av tanken og reduserer antallet sveiser. Dette betyr mindre utmattelsesutsatte detaljer i inneslutningssystemet og en billigere løsning sammenlignet med en ordinær avstivet konstruksjon. Det tredje tankorganet er avstivet på grunn av sin flate natur og på grunn av de lokale kreftene forårsaket av bunnstøttesystemet. Et eksempel på et avstivingsarrangement er illustrert i fig. 4. F.eks. kan det tredje tankorganet være avstivet med ringformede og radiale avstivere og med radiale dragere. Ringavstiverne kan f.eks. være av sveiset T-type med spor gjennom og festet til de radielle dragerne. De radiale avstiverne er av flatbjelketype og bør generelt være festet som innskutte bærere mellom de flensede ringavstiverne. The first tank member and the second tank member are both unbraced structures. This simplifies the construction of the tank and reduces the number of welds. This means less fatigue-prone details in the containment system and a cheaper solution compared to an ordinary braced construction. The third tank body is braced due to its flat nature and due to the local forces caused by the bottom support system. An example of a bracing arrangement is illustrated in fig. 4. E.g. the third tank member can be braced with annular and radial stiffeners and with radial girders. The ring stiffeners can e.g. be of welded T-type with groove through and fixed to the radial girders. The radial stiffeners are of the flat beam type and should generally be attached as cut-in supports between the flanged ring stiffeners.

Tankanordningen har en senterakse I-l som vist i fig. 1.1 fig. 1 tilsvarer senteraksen I-l en vertikal akse som er vinkelrett på et horisontalplan. Det skal bemerkes at denne vertikale aksen selvfølgelig beveger seg i samsvar med fartøybevegelser under påvirkning av vær og sjøforhold. The tank device has a central axis I-1 as shown in fig. 1.1 fig. 1, the center axis I-1 corresponds to a vertical axis perpendicular to a horizontal plane. It should be noted that this vertical axis naturally moves in accordance with vessel movements under the influence of weather and sea conditions.

Fartøyets tanksystem omfatter et tradisjonelt lasthåndteringssystem, styringssystemer, etc. Et rørtårn (ikke vist) kan være tilveiebrakt i tankanordningen for beskyttelse av lastrør og adgang til bunnen av tanken. Tårnet penetrerer toppen av tanken som danner en kuppel hvor alle koblingene til tanken er arrangert. Tårnet bør også støtte sprayingssystemet. The vessel's tank system includes a traditional cargo handling system, steering systems, etc. A pipe tower (not shown) may be provided in the tank arrangement for protection of cargo pipes and access to the bottom of the tank. The tower penetrates the top of the tank which forms a dome where all the connections to the tank are arranged. The tower should also support the spraying system.

Tanksystemet bør også være tilpasset med oppløftstoppeanordninger i tilfelle at fartøyets lasterom blir fylt med sjøvann eller ballastvann. Dette er i samsvar med IMO sine og Classification Societies' regler. The tank system should also be fitted with uplift stop devices in the event that the vessel's hold is filled with seawater or ballast water. This is in accordance with the IMO's and Classification Societies' rules.

En første støtteanordning 5 er tilveiebrakt mellom det tredje tankorganet 3 og et skrog hos fartøyet, for å støtte vekten til tankanordningen. Den første støtteanordningen 5 er tilveiebrakt minst delvis under det tredje tankorganet 3.1 fig. 1 er det vist at den øvre støtteanordningen 5 omfatter støtteblokker, anbrakt mellom den koniske nedre overflaten av det tredje tankorganet og skroget til fartøyet. A first support device 5 is provided between the third tank member 3 and a hull of the vessel, to support the weight of the tank device. The first support device 5 is provided at least partially under the third tank member 3.1 fig. 1 it is shown that the upper support device 5 comprises support blocks, placed between the conical lower surface of the third tank member and the hull of the vessel.

Støtteblokkene kan ha en øvre skrånende overflate tilpasset til den koniske bunnoverflaten. Alternativt er bunnen til skroget skrånende tilsvarende til tankanordningen og rektangulære støtteblokker kan anvendes. The support blocks may have an upper sloping surface adapted to the conical bottom surface. Alternatively, the bottom of the hull is sloped corresponding to the tank arrangement and rectangular support blocks can be used.

Støtteblokkene kan være laget av komprimert, laminert treverk eller andre materialer med lignende egenskaper med tanke på temperatur og robusthet. Formålet med den koniske geometrien, f.eks. sammenlignet med en torisfærisk geometri, er at når tanken krymper under nedkjøling, vil tankbunnen alltid holde seg i kontakt med støttene. The support blocks can be made of compressed, laminated wood or other materials with similar properties in terms of temperature and robustness. The purpose of the conical geometry, e.g. compared to a torispherical geometry, is that when the tank shrinks during cooling, the tank bottom will always stay in contact with the supports.

Under skipsbevegelser vil tanksystemet være eksponert for tversgående og langsgående belastninger som vil forsøke å tvinge tanksystemet ut av sin initiale posisjon ved støtteblokkene. I slike tilfeller vil friksjonene mellom støtteblokkene og den koniske bunnflaten være den hovedmotvirkende stopperen for tanken for å holde seg i posisjon. Følgelig har den koniske formen til det tredje tankorganet en tilleggsoppgave relatert til å låse tanken ved introduksjon av krefter som er normalt på tankskallet og dermed motvirker bevegelsesbelastninger. During ship movements, the tank system will be exposed to transverse and longitudinal loads which will try to force the tank system out of its initial position at the support blocks. In such cases, the friction between the support blocks and the conical bottom surface will be the main counteracting stop for the tank to stay in position. Accordingly, the conical shape of the third tank member has an additional task related to locking the tank by introducing forces normal to the tank shell and thus counteracting movement loads.

Imidlertid, dersom tankanordningen er relativt tom, er det en risiko at de sideveis bevegelseskreftene vil overstige den horisontale friksjonskraften hos støttene. Følgelig kan tanksystemet omfatte stoppemidler (ikke vist) for å hindre eller begrense slike sideveis bevegelser. Slike stoppemidler kan være tilveiebrakt som en del av den første støtteanordningen. However, if the tank device is relatively empty, there is a risk that the lateral movement forces will exceed the horizontal friction force of the supports. Accordingly, the tank system may include stopping means (not shown) to prevent or limit such lateral movements. Such stopping means may be provided as part of the first support device.

Det skal bemerkes at dersom vinkelen a er stor nok, vil disse stoppemidlene kunne utelates, siden den horisontale komponenten til friksjonskreftene mellom den koniske bunnflaten og den første støtteanordningen vil være stor nok til å motvirke enhver sideveis eller langsgående belastning. It should be noted that if the angle a is large enough, these stops can be omitted, since the horizontal component of the frictional forces between the conical bottom surface and the first support device will be large enough to counteract any lateral or longitudinal loading.

Den koniske formen til det tredje tankorganet bør til slutt drenere den flytende gassen til pumper anbrakt i midten av tanken. The conical shape of the third tank member should eventually drain the liquefied gas to pumps located in the center of the tank.

En andre støtteanordning 4 er minst delvis tilveiebrakt langs periferien av tankanordningen, for støtte av tankanordningen til skroget hos fartøyet. Den andre støtteanordningen 4 støtter hovedsakelig tankanordningen i et plan vinkelrett på senteraksen I-l, for treghetsbelastninger og skvulpebelastninger. A second support device 4 is at least partially provided along the periphery of the tank device, for supporting the tank device to the hull of the vessel. The second support device 4 mainly supports the tank device in a plane perpendicular to the center axis I-1, for inertia loads and splash loads.

Den andre støtteanordningen 4 er fleksibel i en første retning parallell på senteraksen I-l til tankanordningen. Videre er den andre støtteanordningen 4 fleksibel i en andre retning vinkelrett på periferien til tankanordningen. Denne andre retningen er også vinkelrett på den første retningen for enhver posisjon langs periferien. Videre er den andre støtteanordningen 4 stiv i en tredje retning tangentielt på periferien til tankanordningen. The second support device 4 is flexible in a first direction parallel to the central axis I-1 of the tank device. Furthermore, the second support device 4 is flexible in a second direction perpendicular to the periphery of the tank device. This second direction is also perpendicular to the first direction for any position along the periphery. Furthermore, the second support device 4 is rigid in a third direction tangential to the periphery of the tank device.

Formålet med denne geometrien er å minimere lokale belastninger i tankskallet på grunn av deformasjoner i skipskroget, typisk vinkelrett på tankskroget, og på grunn av krympingen av tanken, begge mens den holder tanken i posisjon under bevegelser. Dette sikres ved å anvende den fleksible naturen sammen med den stive naturen til støtten 360° rundt periferien. The purpose of this geometry is to minimize local stresses in the tank shell due to deformations in the ship's hull, typically perpendicular to the tank hull, and due to the shrinkage of the tank, both while holding the tank in position during movements. This is ensured by using the flexible nature together with the rigid nature of the support 360° around the periphery.

Den andre støtteanordningen 4 kan være kontinuerlig langs periferien til tankanordningen, eller kan være diskontinuerlig, dvs. omfattende flere støtteanordninger tilveiebrakt med intervaller langs periferien til tankanordningen. Det henvises nå til fig. 2, som illustrerer en utførelsesform av den andre støtteanordningen 4.1 denne utførelsesformen omfatter den andre støtteanordningen 4 en korrugert plateanordning 30 med en første ende 31 koblet til tankanordningen, en andre ende 32 koblet til skroget hos fartøyet. Endene kan f.eks. være koblet til skroget og tankene ved hjelp av sveising. The second support device 4 may be continuous along the periphery of the tank device, or may be discontinuous, i.e. comprising several support devices provided at intervals along the periphery of the tank device. Reference is now made to fig. 2, which illustrates an embodiment of the second support device 4.1 this embodiment, the second support device 4 comprises a corrugated plate device 30 with a first end 31 connected to the tank device, a second end 32 connected to the hull of the vessel. The ends can e.g. be connected to the hull and tanks by means of welding.

Som illustrert i fig. 2 er den korrugerte plateanordningen fleksibel i en første retning Y parallell med senteraksen I-l til tankanordningen, den er fleksibel i en andre retning Z vinkelrett på periferien til tankanordningen, og den er stiv i en tredje retning X tangentielt til periferien hos tankanordningen. I fig. 2 er det vist at alle tre retningene X, Y og Z er vinkelrette til hverandre ved ethvert punkt langs periferien. As illustrated in fig. 2, the corrugated plate assembly is flexible in a first direction Y parallel to the center axis I-1 of the tank assembly, it is flexible in a second direction Z perpendicular to the periphery of the tank assembly, and it is rigid in a third direction X tangential to the periphery of the tank assembly. In fig. 2 it is shown that all three directions X, Y and Z are perpendicular to each other at any point along the periphery.

Den korrugerte plateanordningen 30 omfatter minst én korrugering. Den korrugerte plateanordningen 30 kan være laget av flere sammensveisede plater eller kan være laget av én plate som er bøyd to eller flere ganger for å danne korrugeringen. The corrugated plate device 30 comprises at least one corrugation. The corrugated plate assembly 30 may be made of several plates welded together or may be made of one plate bent two or more times to form the corrugation.

I fig. 2 er korrugeringen i det vesentlige rettvinklet. Imidlertid kan korrugeringen også være i det vesentlig U-formet eller ha en lignende form som gir den samme stivhetskarakteristikken som beskrevet ovenfor. In fig. 2, the corrugation is essentially right-angled. However, the corrugation may also be substantially U-shaped or have a similar shape which provides the same stiffness characteristic as described above.

I den foreliggende utførelsesformen er den andre støtteanordningen 4 festet til tankanordningen nær koblingsgrensesnittet eller forbindelsen 12 mellom det første tankorganet 1 og det andre tankorganet 2. Dermed har den andre støtteanordningen 4 et ekstra formål for støtte av forbindelsen 12 hvor den lokale platebøyingen vil inntreffe på grunn av endret geometri. In the present embodiment, the second support device 4 is attached to the tank device near the coupling interface or connection 12 between the first tank member 1 and the second tank member 2. Thus, the second support device 4 has an additional purpose for supporting the connection 12 where the local plate bending will occur due to of changed geometry.

I en situasjon hvor en tom tank fylles med kryogenisk flytende gass vil tanken trekke seg sammen på grunn av temperaturendringen. Dermed vil den koniske bunnoverflaten til det tredje tankorganet gli langs den øvre skrånende overflaten til støtteblokkene. Følgelig vil tankanordningen bevege seg i en avstand nedover i retningen til den sentrale aksen I-l. Denne bevegelsen tillates på grunn av fleksibiliteten til den andre koblingsanordningen 4 i retningen Y. Den motsatte bevegelsen når tankanordningen oppvarmes, er også tillatt. In a situation where an empty tank is filled with cryogenic liquefied gas, the tank will contract due to the temperature change. Thus, the conical bottom surface of the third tank member will slide along the upper inclined surface of the support blocks. Accordingly, the tank assembly will move a distance downward in the direction of the central axis I-1. This movement is allowed due to the flexibility of the second coupling device 4 in the direction Y. The opposite movement when the tank device is heated is also allowed.

I fig. 3 er en situasjon hvor tanksystemet påvirkes av en treghetskraft F. Som vist vil fleksibiliteten til den andre støtteanordningen dempe påvirkningen ved periferien av tanken i enkeltområder indikert ved områdene bemerket A. Imidlertid vil tankanordningen holdes i posisjon relativt skroget til fartøyet i andre områder bemerket B på grunn av stivheten til den andre støtteanordningen. Det skal bemerkes at fig. 3 er svært forenklet. In fig. 3 is a situation where the tank system is affected by an inertial force F. As shown, the flexibility of the second support device will dampen the impact at the periphery of the tank in individual areas indicated by the areas noted A. However, the tank device will be held in position relative to the hull of the vessel in other areas noted B on due to the stiffness of the second support device. It should be noted that fig. 3 is very simplified.
