Description
Anordning for opplagring av separate tanker ombord i skip. Device for storing separate tanks on board ships.
Foreliggende oppfinnelse vedrører en anordning for opplagring av separate tanker ombord i skip, og er særlig rettet mot en anordning for opplagring av-tanker for transport av flytende ' gas-ser, såsom metan, etylen, klor og lignende gasser. The present invention relates to a device for storing separate tanks on board a ship, and is particularly aimed at a device for storing tanks for the transport of liquefied gases, such as methane, ethylene, chlorine and similar gases.
Opplagringen av separate tanker ombord i skip byr på en rekke problemer. En skipskonstruksjon er utsatt for bevegelser rent generelt, og i tillegg kommer de dynamiske påkjenninger fra tanken. Ved nedkjølte laster har man dessuten de termiske bevegelser som følge av at den flytende gass i tanken kan ha en.meget lav temperatur. The storage of separate tanks on board ships presents a number of problems. A ship structure is exposed to movements in general, and in addition the dynamic stresses from the tank. In the case of refrigerated loads, there are also thermal movements as a result of the fact that the liquid gas in the tank can have a very low temperature.
Ved opplagring av tanker på land kan man med fordel benytte kraftige og stive bærekonstruksjoner, f. eks. søyler. Ved opplagring ombord i skip er forholdene annerledes og vil man anvende de kjente bærekonstruksjoner ombord i skip, så vil disse bærekonstruksjoner bli for store og plasskrevende, dersom de overhodet skal kunne motstå de forskjellige krefter som kommer til virkning ombord i skip når disse f. eks. stamper eller ruller. When storing tanks on land, it is advantageous to use strong and rigid support structures, e.g. columns. When storing on board a ship, the conditions are different and if you want to use the known load-bearing structures on board a ship, then these load-bearing structures will be too large and require space, if they are to be able to withstand the various forces that come into effect on board a ship when these e.g. . stomps or rolls.
For opplagring av separate tanker ombord i skip er det kjent å benytte støtter med leddinnretninger inkorporert i konstruksjonen. Det er også kjent å henge opp eksempelvis kuletanker i.fjærelementer. For the storage of separate tanks on board ships, it is known to use supports with articulated devices incorporated in the construction. It is also known to suspend, for example, ball tanks in spring elements.
Foreliggende oppfinnelse tar sikte på å tilveiebringe en opplagringsanordning som er enkel, samtidig som den konstruktivt sett er fullt ut tilfredsstillende. The present invention aims to provide a storage device which is simple, while being structurally fully satisfactory.
Ifølge oppfinnelsen er det tilveiebragt en anordning for opplagring av tanker ombord i skip, for transport av flytende gasser, og det som kjennetegner oppfinnelsen er at tanken er innspent i skroget ved hjelp av en i og for seg kjent sylindrisk eller svakt konisk kontinuerlig platekonstruksjon i form av et tankskjørt og ved åt tankskjør-tet er delvis isolert, slik at øvre del av tankskjørtet får tilnærmet samme temperatur som tanken, mens tankskjørtet nedentil får tilnærmet samme temperatur som i'rommet omkring tanken, hvorved varmespenninger reduseres. Med oppfinnelsen er det gjort mulig å opplagre tanker, som kan være av betydelig størrelse i forhold til skipets dimensjoner, ombord i et skip ved hjelp av et skjørt, som er en i seg selv enkel konstruksjon. According to the invention, a device is provided for the storage of tanks on board ships, for the transport of liquefied gases, and what characterizes the invention is that the tank is clamped in the hull by means of a known per se cylindrical or slightly conical continuous plate construction in the form of a tank skirt and when the tank skirt is partially insulated, so that the upper part of the tank skirt receives approximately the same temperature as the tank, while the tank skirt below receives approximately the same temperature as in the space around the tank, whereby thermal stresses are reduced. With the invention, it has been made possible to store tanks, which can be of considerable size in relation to the ship's dimensions, on board a ship by means of a skirt, which is a simple construction in itself.
Et slikt skjørt gir en gunstig overføring av krefter mellom tank og opplagring, idet man unngår store eksentrisiteter. På grunn av den omløpende forbindelse mellom tank og opplagring får man også en gunstig overføring av horisontale og vertikale krefter under skipets gang i sjøen. Når det dreier seg om tanker for nedkjølte laster, oppnår man dessuten en eliminering eller en vidtgående begrensning av varmespenninger forårsaket av tankens krymping relativt skroget. Ifølge oppfinnelsen skal videre tankskjørtet være delvis isolert. Den delvise isolasjon utføres da slik at bæreflensen får tilnærmet samme temperatur som i rommet omkring tanken. Derved unngås vesentlige termiske bevegelser i flensområdet. Ved isoleringen får man samtidig i øvre del av tankskjørtet tilnærmet samme temperatur som for tanken. For ytterligere å forbedre isoleringens effekt, kan man utelate isoleringen i den mellom tankskjørt og tank dannede kile og eventuelt utfylle dette hulrom med et varmeledende materiale. Such a skirt provides a favorable transfer of forces between tank and storage, avoiding large eccentricities. Due to the continuous connection between tank and storage, you also get a favorable transfer of horizontal and vertical forces during the ship's passage in the sea. When it comes to tanks for refrigerated loads, one also achieves an elimination or a far-reaching limitation of thermal stresses caused by the shrinking of the tank relative to the hull. According to the invention, the tank skirt must also be partially insulated. The partial insulation is then carried out so that the bearing flange gets approximately the same temperature as in the space around the tank. Thereby, significant thermal movements in the flange area are avoided. At the same time, with the insulation, the upper part of the tank skirt achieves approximately the same temperature as for the tank. To further improve the insulation's effect, you can leave out the insulation in the wedge formed between the tank skirt and the tank and optionally fill this cavity with a heat-conducting material.
Skjærtet kan, når det foreligger en tilstrekkelig stiv skrog-konstruksjon, være direkte fastsyeiset i skroget, da skjørtet har en iboende evne til opptak av deformasjoner. The skirt can, when there is a sufficiently rigid hull construction, be directly sewn into the hull, as the skirt has an inherent ability to absorb deformations.
Ifølge oppfinnelsen kan imidlertid skjørtet isteden ende i According to the invention, however, the skirt can instead end in
en bæreflens, som hviler på en skrogmontert fundamentflens. a support flange, which rests on a hull-mounted foundation flange.
Fordelaktig kan fundamentflensen bæres avet skrogmontert. skjørt. Dette byr på den konstruksjonsmessige fordel som består i at to like konstruksjoner, nemlig de to skjørt, vil stå mot hverandre, hvilket er en stor fordel ved konstruksjoner av denne type^ hvor man eventuelt må regne med termiske bevegelser. Advantageously, the foundation flange can be carried without the hull mounted. skirt. This offers the constructional advantage which consists in the fact that two similar constructions, namely the two skirts, will stand against each other, which is a great advantage in constructions of this type where thermal movements may have to be taken into account.
Ifølge oppfinnelsen kan det hensiktsmessig mellom bæreflensen og fundamentflensen være innlagt elastiske legemer, såsom gummiputer, tallerkenfjærer eller lignende. Disse elastiske legemer vil ta opp vridninger som/følge av bevegelser i skroget.. According to the invention, elastic bodies, such as rubber cushions, disc springs or the like, can suitably be inserted between the support flange and the foundation flange. These elastic bodies will take up twists as a result of movements in the hull.
For opptak av dynamiske krefter og for å tillate termisk be-virkede bevegelserj anordnes det hensiktsmessig innbyrdes samvirkende låseorgan på bæreflensen og fundament flensen.. Ved en fordelaktig ut-førelsesform er låseorganene anordnet langs deler av flensene., henholdsvis tverrskips og langskips;. Det vil si at låseorganene bare er anordnet på utvalgte steder langs flensene. Ved en slik foretrukken anordning av låseorganene er det fordelaktig å utføre disse slik at de i de. enkelte områder bare har låsevirkning langskips, henholdsvis tverrskips, dvs. at låseorganene har en viss "radiell" bevegelsesfrihet. Dette gir en meget gunstig fastlåsing av tanken til fundamentet, idet termiske bevegelser ikke vil hindres i vesentlig grad. In order to absorb dynamic forces and to allow thermally induced movements, an appropriately interacting locking device is arranged on the support flange and the foundation flange. In an advantageous embodiment, the locking devices are arranged along parts of the flanges, respectively transverse and longitudinal. This means that the locking means are only arranged at selected locations along the flanges. With such a preferred arrangement of the locking means, it is advantageous to design these so that they in the. certain areas only have a locking effect longitudinally, respectively transversely, i.e. that the locking devices have a certain "radial" freedom of movement. This provides a very favorable locking of the tank to the foundation, as thermal movements will not be hindered to a significant extent.
Ifølge oppfinnelsen kan" tankskjørtet hensiktsmessig være for-bundet med tanken ved hjelp av en mellom tankskjørtet og tanken innskutt overgangskonstruksjon, hvilken overgangskonstruksjon da samtidig kan tjene til avstiving av tanken. Ved -en direkte forbindelse mellom tankskjørt og tank kan man for å $ke innfestingsarealet og gjøre inn-sveisingen mykere, -hensiktsmessig utføresveisesømmen mellom tankskjør-tet. og tanken med bølgeform. According to the invention, the tank skirt can conveniently be connected to the tank by means of a transition structure inserted between the tank skirt and the tank, which transition structure can then simultaneously serve to stiffen the tank. With a direct connection between the tank skirt and the tank, the mounting area can be and make the welding in softer, -expediently perform the welding seam between the tank skirt and the tank with a wave form.
Oppfinnelsen skal forklares nærmere under henvisning til tegningene som viser foretrukne utførelseseksempier av oppfinnelsen. The invention shall be explained in more detail with reference to the drawings which show preferred embodiments of the invention.

I fig. 1 er skipet generelt betegnet med 1. Skipet har side-tanker 2 og H og bunntanker 3- Et omløpende fundamentskjørt 12 rager opp fra skipets indre bunn og er fastsveiset til denne. Øverst har fundamentskjørtet .12 en omløpende, fundamentflens 8. På denne fundamentflens 8 hviler kuletanken 5 ved hjelp av det fra kuletankens ekva-torplan tangensielt rettede tankskjørt 6 som nederst går over i en bæreflens 7. I fig. 1 er det mellom bæreflensen 7 og fundament flensen 8 antydet et mellomrom 11. Dette mellomrom er utfylt, av elastiske legemer for opptagelse av vridningsbevegelser, og av låseorgan for hind-ring av dynamiske bevegelser (se fig. 5.-7). In fig. 1, the ship is generally denoted by 1. The ship has side tanks 2 and H and bottom tanks 3- A circumferential foundation skirt 12 projects from the inner bottom of the ship and is welded to it. At the top, the foundation skirt .12 has a circumferential foundation flange 8. On this foundation flange 8, the ball tank 5 rests with the help of the tangentially directed tank skirt 6 from the ball tank's equatorial plane, which at the bottom merges into a support flange 7. In fig. 1, a space 11 is indicated between the support flange 7 and the foundation flange 8. This space is filled by elastic bodies for recording twisting movements, and by locking means for preventing dynamic movements (see fig. 5.-7).
Kuletanken 5 hviler ellers fritt på fundamentet. Normalt vil kuletanken 5 holde seg på plass, men ved en eventuell oversvømmelse i skipsrommet vil kuletanken kunne flyte opp, og på skipets innvendige sider er det derfor anordnet braketter 9 og 10 som ligger over flensen 7 og hindrer en oppadrettet bevegelse av kuletanken 5. Istedenfor de antydede braketter kan man naturligvis også eksempelvis anvende bolt-forbindelser mellom flensene. The ball tank 5 otherwise rests freely on the foundation. Normally, the ball tank 5 will stay in place, but in the event of flooding in the ship's hold, the ball tank will be able to float up, and brackets 9 and 10 are therefore arranged on the inside of the ship, which lie above the flange 7 and prevent an upward movement of the ball tank 5. Instead the indicated brackets can of course also be used, for example, with bolted connections between the flanges.
I fig. 2 er vist en utførelse hvor en kuletank 32 er opplagret i skipet 33 ved hjelp av et skjørt 31. Skjørtet er sveiset direkte fast i skroget. Denne utførelse kan med fordel benyttes når skroget er stivt nok. In fig. 2 shows an embodiment where a ball tank 32 is stored in the ship 33 by means of a skirt 31. The skirt is welded directly to the hull. This design can be advantageously used when the hull is stiff enough.
I fig. 3 er vist en utførelse hvor en kuletank 36 er hengende opplagret i skipet 34 ved hjelp av.det svakt koniske skjørt 35 som øverst er fastsveiset til skroget. In fig. 3 shows an embodiment where a ball tank 36 is suspended stored in the ship 34 by means of the slightly conical skirt 35 which is welded to the hull at the top.
I fig. ter vist en opplagring av en sirkelsyllndrisk tank In fig. shows a storage of a circular cylindrical tank
39 i et skip 37 ved hjelp av ét skjørt 38. 39 in a ship 37 by means of one skirt 38.
De ovenfor i forbindelse med utførelsen i fig. 1 nevnte elastiske legemer kan eksempelvis utføres som gummiputer 13j som vist i fig. 5. Gummiputene 13 anordnes med innbyrdes avstand og ute ved borde, og på hver side av skipets senterlinje er det mellom dé enkelte gummiputer 13 anordnet spesielle låseorgan 14, henholdsvis 15. The above in connection with the embodiment in fig. 1 mentioned elastic bodies can for example be made as rubber pads 13j as shown in fig. 5. The rubber pads 13 are arranged at a distance from each other and outboard, and on each side of the ship's centreline there are special locking devices 14 and 15 arranged between the individual rubber pads 13.
En utførelse av låseorganene er vist i fig. 6 og 7. På fundamentf lensen 8 er det fastsjveiset braketter 16, 17, lB og 19, hvis konstniksjon. vil _gå .frem av fig..3 og 4. Brakettene 1-6 - 19 er slik anordnet at det mellom,brakettene 16, 17 og brakettene 18, 19 dannes An embodiment of the locking means is shown in fig. 6 and 7. On the foundation flange 8 there are welded brackets 16, 17, 1B and 19, whose construction. will proceed from fig..3 and 4. The brackets 1-6 - 19 are arranged in such a way that between the brackets 16, 17 and the brackets 18, 19 are formed
■et over fundamentflensens 8 bredde forløpende låsespor 20. Mellom de respektive brakettpar 16, 17 og 18, 19 dannes det på tilsvarende måte et føringsspor 21. På hæreflensen 7 er det fastsveiset en trapesfor-met plate 22 .som når kuletanken er montert på plass, rager-ned I før-ingssporet 21 og har en viss klaring i retning av dobbeltpilen A. Fra hver side av platen 22 rager det ut en kasseformet sveisekonstruksjon 23, henholdsvis 24. Disse kasseformede sveisékonstruksjoner er slik dimensjonert at de når kuletanken er montert, passer ned i låsesporet 20, slik det klart går frem av fig. 6 og 7. ■ a locking groove 20 running across the width of the foundation flange 8. Between the respective pairs of brackets 16, 17 and 18, 19, a guide groove 21 is formed in a similar way. On the anchor flange 7, a trapezoidal plate 22 is welded, as when the ball tank is mounted in place , protrudes down into the guide groove 21 and has a certain clearance in the direction of the double arrow A. From each side of the plate 22, a box-shaped welding structure 23, respectively 24 protrudes. These box-shaped welding structures are dimensioned in such a way that when the ball tank is mounted, fits into the locking slot 20, as is clear from fig. 6 and 7.
Antar man at den i fig. 6 og 7 viste konstruksjon represen-terer et av. låseorganene 15 i fig. 5 , så vil låseorganet, som altså består'av samvirkende elementer anordnet henholdsvis på fundamentflen-.' sen og bæreflensen, hindre tverr-sklps bevegelser, idet de kasseformede sveisekonstruksjoner 2.3, 2M er tilpasset låsesporet 20 uten' vesentlig klaring. Derimot vil låseorganet 15-ha en viss bevegelsesmulighet i langskipsretningen, grunnet den nevnte klaring mellom platen 22 og f-ør-ingssporet 21; Låseorganene 14, som befinner seg ute i borde, har samme konstruksjon -som låseorganene 15, og i dette område vil hvert enkelt låseorgan 14 være sperret mot langskips bevegelser, men ha en viss•bevegelsesmulighet i tverrskipsretningen. Med de beskrevne låseorgan er således kuletanken sikret mot dynamiske bevegelser i tverrskips- og langskipsretningen, samtidig som flensene 7 og 8 har en viss bevegelsesmulighet relativt hverandre. Klaringene mellom de respektive plater 22 og tilhørende føringsspor 21 gir .nemlig mulighet for å tillate termiske bevegelser, og der hvor det ikke finnes noen låseorgan ligger flensene bare løst an mot hverandre. Assuming that the one in fig. The construction shown in 6 and 7 represents one of the locking means 15 in fig. 5, then the locking device, which thus consists of interacting elements arranged respectively on the foundation flange. and the supporting flange, prevent cross-sliding movements, as the box-shaped welding structures 2.3, 2M are adapted to the locking groove 20 without significant clearance. In contrast, the locking member 15 will have a certain possibility of movement in the longitudinal direction, due to the aforementioned clearance between the plate 22 and the guide groove 21; The locking members 14, which are located outboard, have the same construction as the locking members 15, and in this area each individual locking member 14 will be blocked against longboard movements, but will have a certain •movement possibility in the transverse direction. With the described locking means, the ball tank is thus secured against dynamic movements in the transom and longitudinal direction, while the flanges 7 and 8 have a certain possibility of movement relative to each other. The clearances between the respective plates 22 and associated guide grooves 21 give the possibility of allowing thermal movements, and where there is no locking device, the flanges only lie loosely against each other.
Istedenfor gummiputene 13 kan man naturligvis også anvende andre egnede elastiske legemer, eksempelvis tallerkenfjÆrer, og låseorganene kan også ha andre egnede utførelser. Plaseringen av de elastiske legemer kan også endres relativt det viste plaseringsmønster. Instead of the rubber pads 13, one can of course also use other suitable elastic bodies, for example disc springs, and the locking members can also have other suitable designs. The placement of the elastic bodies can also be changed relative to the placement pattern shown.
I fig. 8 er en mulig sveiseforbindelse mellom tankskjørtet 6 og kuletanken 5 vist nærmere. ' Som mån ser er sveisesømmen 25 mellom tankskjørtet 6 og kuletanken 5 utformet som en bølgeformet linje. På denne måten får man større innfestingsareal og også en mykere innfest-ing. De i tankskjørtet 6 utførte hull 26 tjener til spenningsfordel-ing i dette påkjente område. In fig. 8, a possible welding connection between the tank skirt 6 and the ball tank 5 is shown in more detail. As can be seen, the welding seam 25 between the tank skirt 6 and the ball tank 5 is designed as a wavy line. In this way, you get a larger attachment area and also a softer attachment. The holes 26 made in the tank skirt 6 serve for stress distribution in this exposed area.
Når flytende -gass, såsom eksempelvis metan, som lagres med en temperatur på ca. l60°, fylles i kuletanken 5> vil kuletanken trekke seg sammen. Her kommer fordelen med tankskjørtet 6 tydelig frem. Tankskjørtet 6 tjener til utligning av tankens sammentrekning, slik at man i flensområdet får så små bevegelser som mulig. For ytterligere å hindre termiske bevegelser er, som vist i fig. 9, skjørtet 6 forsynt med en i retning mot flensen 7 avtagende isolering 28. Denne isolering 28- danner en fortsettelse av den for tanken 5 vanlige isolering 27. Ved hjelp av varmetekniske beregninger kan man bestemme isoleringens utstrekning og form, slik at man oppnår en temperaturgra-dient i skjørtet som resulterer i akseptable termiske spenninger. Den nedre del av skjørtet er uisolert, slik at flensen 7 får tilnærmet samme temperatur som i rommet omkring kuletanken, og altså samme temperatur som flensen 8. I innsveisingsområdet 30 vil det tilnærmet være samme temperatur som i kuletanken, og oppnåelsen av denne effekt styr-kes ved at det i utførelseseksempelet i kilen 29 istedenfor isolering er anordnet et varmeledende medium. When liquefied gas, such as for example methane, which is stored at a temperature of approx. l60°, is filled in the ball tank 5> the ball tank will contract. Here, the advantage of the tank skirt 6 becomes clear. The tank skirt 6 serves to compensate for the contraction of the tank, so that in the flange area there is as little movement as possible. To further prevent thermal movements, as shown in fig. 9, the skirt 6 is provided with an insulation 28 that decreases in the direction towards the flange 7. This insulation 28 forms a continuation of the insulation 27 common to the tank 5. With the help of thermal engineering calculations, the extent and shape of the insulation can be determined, so that a temperature gradient in the skirt which results in acceptable thermal stresses. The lower part of the skirt is uninsulated, so that the flange 7 gets approximately the same temperature as in the space around the ball tank, and therefore the same temperature as the flange 8. In the welding area 30 it will be approximately the same temperature as in the ball tank, and the achievement of this effect controls is done by the fact that, in the design example, a heat-conducting medium is arranged in the wedge 29 instead of insulation.
I fig. 10 er det vist en annen mulig utførelse av forbindelsen mellom et tankskjørt og en tank. Forbindelsen består av en ring 4l med større tykkelse enn tankveggen, hvilken ring er innsveiset i tankveggen 40, 45 og utgjør endel av den. I ringens underkant er det anordnet et spor 42 med en form som er bestemt ut fra spenningsbildet i dette område. Det derved fremkomne ytre fremspring 43 danner en ån-visning for påsveising av skjørtet 46. Ringens 4l overkant er avmyket ved 44 mot tankveggen 40. In fig. 10 shows another possible embodiment of the connection between a tank skirt and a tank. The connection consists of a ring 4l with a greater thickness than the tank wall, which ring is welded into the tank wall 40, 45 and forms part of it. In the lower edge of the ring, a groove 42 is arranged with a shape that is determined on the basis of the stress pattern in this area. The resulting outer projection 43 forms an opening for welding on the skirt 46. The upper edge of the ring 4l is softened at 44 against the tank wall 40.
Fig. 11 og 12 viser nok en mulighet for feste av et tankskjørt 47 til en tank ved hjelp av en overgangskonstruksjon, som i dette til-felle består av to på tankens 48 ytterside fastsveisede omløpende profiler 54 og 49, hvilke profiler er innbyrdes avstivet med plater 50. Tankskjørtets øvre kant 51 har bølgeform og er fastsveiset. til platene Figs. 11 and 12 show yet another possibility for attaching a tank skirt 47 to a tank by means of a transition structure, which in this case consists of two circumferential profiles 54 and 49 welded to the outside of the tank 48, which profiles are mutually braced with plates 50. The upper edge 51 of the tank skirt has a wave shape and is welded. to the plates
50 og profilen 49. På innsiden av. tanken er det for avstivning fastsveiset to omløpende profiler 52 og 53, mellom hvilke det med passende mellomrom er Innsveiset avstivnlngsplater 55^ 50 and the profile 49. On the inside of. to the tank, for bracing, two circumferential profiles 52 and 53 are welded, between which there are welded bracing plates 55^ at suitable intervals
Fig. 13 viser en annen mulig overgangskonstruksjon mellom skjørt og tank. På tanken 62 er -det fastsveiset en omløpende flens 56. Til skjørtet 57. er det fastsveiset en flens 58. Mellom de to flenser 56 og .48 e'r det innlagt j us te rb are mellomlegg 59, 61. Flensene er bol-tet sammen som antydet med den stiplede linje 60. Fig. 13 shows another possible transition construction between skirt and tank. A circumferential flange 56 is welded to the tank 62. A flange 58 is welded to the skirt 57. Between the two flanges 56 and 48, adjustable spacers 59, 61 are inserted. The flanges are joined as indicated by the dashed line 60.
Nærmere detaljer ved oppfinnelsen er i det foregående for-klart under henvisning til opplagringen av en kuletank som skjematisk vist i fig.l. Disse detaljer kan naturligvis med eventuelle tilpas-ninger også anvendes I forbindelse med eksempelvis de opplagringsmulig-heter som er vist i fig. 2, 3 og 4, hvilket vil være nærliggende for en fagmann ved-et studium av den foregående beskrivelse. Spesielt skal her fremheves at hruk av fundamentflens og bæreflens også kan anvendes for de i fig. 2 og 3 antydede løsninger og at den spesielle Isolerings-utførélse også naturligvis kan tilpasses ^eksempelvis ved de i fig. 10.-13 viste overgangskonstruksjoner. Further details of the invention are explained above with reference to the storage of a ball tank as schematically shown in fig.l. These details can of course, with any adaptations, also be used in connection with, for example, the storage options shown in fig. 2, 3 and 4, which will be obvious to a person skilled in the art from a study of the preceding description. In particular, it must be emphasized here that creases of the foundation flange and support flange can also be used for those in fig. 2 and 3 suggested solutions and that the special Isolation design can also of course be adapted ^ for example by those in fig. 10.-13 showed transitional constructions.
Skjørtene kan i praksis ha konstruktivt betingede utskjærin-ger , .avstivninger etc., slik man kjenner det fra platekonstruksjoner. Skjørtets tilknytningsområde på-tanken kan også ligge utenfor ekvato-rialplanet, henholdsvis det midtre horisontalplan. Når forholdene til-later det, kan bæreilens og fundamentf lens ligge an mot hverandre uten elastiske mellomlegg. In practice, the skirts can have structurally conditioned cut-outs, bracing etc., as is known from panel constructions. The skirt's attachment area to the tank can also lie outside the equatorial plane, respectively the middle horizontal plane. When the conditions permit, the support flange and the foundation flange can rest against each other without elastic spacers.
