Description

Denne oppfinnelse vedrører en svømmende konstruksjon for stasjonering på havet med maskiner og anlegg for behandling av bunnforekomster, særlig for kondensasjon av gass.. This invention relates to a floating structure for stationing at sea with machines and facilities for the treatment of bottom deposits, in particular for the condensation of gas.

Det ei* kjent å utvinne bunnforekomster i eller under havbunnen, f.eks. jordolje eller naturgass, ved hjelp av såkalte bore-øyer. Disse anvendes imidlertid som regel bare i kystområder eller på banker hvor vanndybden tillater oppstilling av en plattform på havbunnen, og transporten til land av de tilveiebragte produkter f. eks. 'kan skje gjennom rørledninger. I alle de tilfelle hvor vanndybden ikke tillater anvendelse av plattformer på søyler,er utvinning bare mulig fra svømmende plattformer som blir forankret på havbunnen. Da en slik svømmende plattform tross de store dimensjoner påvirkes It is not known to extract bottom deposits in or under the seabed, e.g. crude oil or natural gas, using so-called drilling islands. However, these are usually only used in coastal areas or on banks where the water depth allows the setting up of a platform on the seabed, and the transport to land of the provided products, e.g. 'can happen through pipelines. In all cases where the water depth does not allow the use of platforms on pillars, extraction is only possible from floating platforms that are anchored to the seabed. As such a floating platform, despite its large dimensions, is affected

av sjøgangen og utfører tilsvarende bevegelser,foreligger i en rekke anvendelsestilfelle det problem å lagre behandlingsutstyret.:f or de til havoverflaten transporterte forekomster på en slik måte at de nødvendige maskiner og/eller anlegg i realiteten ikke påvirkes av plattformens bevegelser, men uavhengig av sjøgangen står på et i praksis alltid horisontalt, fundament. of the seaway and performs corresponding movements, in a number of application cases there is the problem of storing the processing equipment.:for deposits transported to the sea surface in such a way that the necessary machines and/or facilities are in reality not affected by the platform's movements, but independent of the seaway stands on a practically always horizontal foundation.

Dette problem for et svømmende prosessanlegg løses ifølge oppfinnelsen ved hjelp av et svømmelegeme med et åpent væskebasseng på oversiden, i hvilket en bæreplattform for behandlingsutstyret holdes flytende. Ved dette sikres at det på plattformen stående utstyr i det vesentlige ikke svaier selv i sterk sjøgang. Dette er særlig viktig ved utvinning av naturgass, da denne av transportårsaker først må flytendegjøres. De for dette krevede kondensasjonsanlegg, spesielt de anvendte varmevekslere, nødvendiggjør en i praksis uen-dret horisontal stilling av bæreplattformen, da bare en hellingsfor-skjell på ± 1° er tillatelig for en utforstyrret drift med full virk-ningsgrad. Denne betingelse kan tilfredsstilles gjennom den flytende lagring av bæreplattformen uavhengig av svømmelegemet. This problem for a floating process plant is solved according to the invention by means of a floating body with an open liquid pool on the upper side, in which a support platform for the processing equipment is kept afloat. This ensures that the equipment standing on the platform essentially does not sway even in strong seas. This is particularly important when extracting natural gas, as this must first be liquefied for transport reasons. The condensing systems required for this, especially the heat exchangers used, necessitate a virtually unchanged horizontal position of the support platform, as only a slope difference of ± 1° is permissible for a disturbed operation with full efficiency. This condition can be satisfied through the floating storage of the support platform independent of the swimming body.

En utførelse av oppfinnelsen er hensiktsmessig ved at sideveggene i bassenget avslutter i avstand ovenfor svømmelegemets vannlinje. På denne måte tilveiebringes en sikker adskillelse av væske-bassenget fra det omgivende hav, idet disse sidevegger samtidig ved en passende høyde tjener som vindbeskyttelse for de anlegg og bygnin-ger som finnes på den i bassenget flytende plattform. An embodiment of the invention is appropriate in that the side walls in the pool end at a distance above the waterline of the swimming body. In this way, a safe separation of the liquid pool from the surrounding sea is provided, as these side walls at the same time at a suitable height serve as wind protection for the facilities and buildings found on the platform floating in the pool.

En videreutvikling av oppfinnelsen utmerker seg ved at plattformen består av flere individuelt flytedyktige deler utløsbart forbundet med hverandre. Fordelen - ved denne utførelse består i at hele anlegget kan ferdigmonteres på land som individuelle enheter og deretter bukseres ut for stasjonering uavhengig av svømmelégemet. An-bringes f.eks. boligkvarterene på en del, prossessanlegget på en an-nen og kraftstasjonen på en tredje del av plattformen, da kan hver del ved graverende forstyrrelser bukseres individuelt ut og slepes i land for reparasjon. Med henblikk på dette er det hensiktsmessig at veggen i bassenget i det minste delvis er utformet portaktig utløsbar. A further development of the invention is distinguished by the fact that the platform consists of several individually floating parts releasably connected to each other. The advantage - of this design is that the entire system can be fully assembled on land as individual units and then stripped out for stationing independently of the swimming body. Attached, e.g. the living quarters on one part, the process plant on another and the power station on a third part of the platform, then in case of serious disturbances, each part can be taken out individually and towed ashore for repair. With this in mind, it is appropriate that the wall in the pool is at least partially designed to be releasable like a gate.

Dessuten er plattformen ifølge oppfinnelsen elastisk forbundet med svømmelégemet. Dette gir en tilstrekkelig bevegelsesfri-het overfor svømmelégemet ved duving omkring en horisonbal akse. I denne forbindelse er det fordelaktig at plattformen er forbundet med svømmelégemet over gassfylte fendere anordnet mellom plattformkanten Furthermore, the platform according to the invention is elastically connected to the swimming body. This provides sufficient freedom of movement for the swimming body when dove around a horizontal axis. In this connection, it is advantageous that the platform is connected to the swimming body via gas-filled fenders arranged between the platform edge

og veggen i bassenget. Ved en passende utforming av fenderne blir det mulig å variere trykket av gassfyllingen ved hjelp av pumper etc. and the wall in the pool. With a suitable design of the fenders, it becomes possible to vary the pressure of the gas filling with the help of pumps etc.

for å endre elastisiteten av disse forbindelseselementer svarende til sjøgangsforholdene. to change the elasticity of these connecting elements corresponding to seagoing conditions.

Oppfinnelsen gis også anvisning på at svømmelégemet er utformet med tanker for lagring av de behandlede produkter. Ved dette blir det mulig å la prossessanlegget arbeide kontinuerlig, mens bort-transporten kan skje periodisk, f.eks. med tankskip, således at pro-duksjonen kan fortsette også ved sterk sjøgang.når skipene ikke kan legge til for å overta de behandlede produkter. The invention also provides instructions that the swimming body is designed with tanks for storing the treated products. This makes it possible to let the process plant work continuously, while the away transport can take place periodically, e.g. with tankers, so that production can continue even in strong seas, when the ships cannot dock to take over the processed products.

Dessuten er det hensiktsmessig at en del av tankene er varmeisolert, særlig ved gasskondensasjon. På denne måte unngås et isbelegg, på svømmelégemet. In addition, it is appropriate that part of the tanks are thermally insulated, particularly in case of gas condensation. In this way, an ice coating on the swimming body is avoided.

En videreutvikling av oppfinnelsen utmerker seg ved at svømmelégemet er rotasjonssymmetrisk utformet med hensyn til dets vertikale akse. Dette gir svømmelégemet ensartede bevegelsesforhold i enhver retning under påvirkning av vindkrefter og sjøgang. A further development of the invention is distinguished by the fact that the swimming body is rotationally symmetrically designed with respect to its vertical axis. This gives the swimming body uniform movement conditions in any direction under the influence of wind forces and sea conditions.

Ifølge oppfinnelsen kan svømmelégemet omfatte flere fortrinnsvis symmetrisk anordnede ballasttanker. Ved hjelp av disse kan svømmelégemet trimmes til enhver tid, hvilket er særlig påkrevet under fylling eller tømming av lagringstankene. Dette er spesielt tilfelle ved kondensasjon av naturgass, da de ulike væskefraksjoner fremkommer i forskjellig mengde, og den vektforskyvning som følger herav kan da utlignes på enkel måte ved hjelp av ballasttankene. According to the invention, the swimming body can comprise several preferably symmetrically arranged ballast tanks. With the help of these, the swimming body can be trimmed at any time, which is particularly required when filling or emptying the storage tanks. This is especially the case with the condensation of natural gas, as the different liquid fractions appear in different amounts, and the resulting weight shift can then be compensated in a simple way with the help of the ballast tanks.

Oppfinnelsen skal forklares nærmere i. det følgende under henvisning til tegningene, hvor: Fig. 1 er et. vertikalt snittriss som viser en utførelse av den omhandlede konstruksjon med et kondensaskonsanlegg for naturgass, og fig. 2 er et snitt etter linjen I I-l I på fig. 1 i mindre målestokk.. The invention shall be explained in more detail in the following with reference to the drawings, where: Fig. 1 is a. vertical sectional view showing an embodiment of the construction in question with a condensing unit for natural gas, and fig. 2 is a section along the line I I-1 I in fig. 1 on a smaller scale..

Den viste konstruksjon omfatter et svømmelegeme 1 som ifølge fig. 2 fortrinnsvis er utformet med sirkeltverrsnitt. Sidevegger 2 The construction shown comprises a swimming body 1 which, according to fig. 2 is preferably designed with a circular cross-section. Side walls 2

i legemet 1 er ført så høyt oppover at de ender i avstand fra vannlinjen 3. På denne måte dannes i det øvre område av legemet 1 et væskebasseng 4 som er adskilt fra det omgivende hav.. Bassenget 4 er fylt ,med en væske (havvann), idet væskeoverflaten i bassenget alt etter neddykkingen av legemet 1 ligger over eller under vannlinjen 3. in the body 1 are led so high up that they end at a distance from the waterline 3. In this way, a liquid pool 4 is formed in the upper area of the body 1 which is separated from the surrounding sea. The pool 4 is filled with a liquid (sea water ), as the liquid surface in the pool is above or below the water line 3 depending on the immersion of the body 1.

I bassenget 4 befinner seg en bæreplattform sammensatt av flere deler 5,6,7. Disse deler er hver for seg flytedyktige og utløsbart forbundet med hverandre. Plattformens dimensjoner er tilpasset slik at den flyter med avstand fra bassengveggen. For å oppnå en fikse-ring er det mellom bassengveggen og plattformen ved kanten av denne regelmessig på omkretsen fordelt et antall gassfylte, elastiske fendere 8 som tillater en relativbevegelse omkring horisontale akser av plattformen overfor svømmelégemet 1. Ved hjelp av fenderne unngås samtidig en dreining av plattformen omkring en vertikal akse i for-hold til legemet 1. In the pool 4 there is a support platform composed of several parts 5,6,7. These parts are individually floatable and releasably connected to each other. The platform's dimensions are adapted so that it floats with distance from the pool wall. In order to achieve a fixing ring, between the pool wall and the platform at the edge of this, a number of gas-filled, elastic fenders 8 are distributed regularly on the circumference, which allow a relative movement around horizontal axes of the platform opposite the swimmer's body 1. By means of the fenders, a rotation of the platform around a vertical axis in relation to the body 1.

Som vist på fig. 2 er legemet 1 fortrinnsvis oppdelt symmetrisk ved hjelp av mellomvegger, slik at det innvendig i dette opp-står en rekke hulrom. Av disse tjener rommene 9 som ballast- og trimmetanker, fortrinnsvis i symmetrisk anordning. Til dette formål er de på kjent måte utstyrt med ballastventiler i det nedre område, og i det øvre område står de i forbindelse med et kompressoranlegg til utdrivning av vann. De øvrige rom er i dette utførelseseksempel bestemt som oppbevaringstanker for de ved gasskondensasjon tilveiebragte flytende fraksjoner. As shown in fig. 2, the body 1 is preferably divided symmetrically by means of intermediate walls, so that a number of cavities arise inside it. Of these, the rooms 9 serve as ballast and trim tanks, preferably in a symmetrical arrangement. For this purpose, they are equipped in a known manner with ballast valves in the lower area, and in the upper area they are connected to a compressor system for expelling water. In this embodiment, the other rooms are designated as storage tanks for the liquid fractions produced by gas condensation.

For å unngå dannelse av et isbelegg på svømmelégemet har tankene for den flytende gass en indre varmeisolering 10. To avoid the formation of an ice coating on the swimming body, the tanks for the liquid gas have internal thermal insulation 10.

I avstand fra veggen 2 er svømmelégemet omgitt av en veggAt a distance from wall 2, the swimming body is surrounded by a wall

.11 som er utformet med et flertall åpninger 12 og tjener som bølge-bryter. .11 which is designed with a plurality of openings 12 and serves as a wave breaker.

Den i bassenget 4 flytende plattform er utformet såledesThe floating platform in pool 4 is designed as such

at det f.eks. på delen 5 er oppført bolig- og verkstedskvarter, på delen 6 som separat enhet hele gasskondensasjonsanlegget, og på delen 7 forsyningsanleggene som kraftverk, vannbehandlingsinstallasjon, trykkluftkompressorer, dampkjeler etc De enkelte deler av platt- that it e.g. on section 5 are residential and workshop quarters, on section 6 as a separate unit the entire gas condensation plant, and on section 7 the supply facilities such as power plant, water treatment installation, compressed air compressors, steam boilers etc. The individual parts of platt-

formen er som nevnt individuelt flytedyktige, men under drift er de fast forbundet med hverandre. Oppdelingen har den fordel at de enkelte seksjoner kan vaere fri av hverandre ved monteringen, og ved større reparasjoner kan de adskilles og slepes individuelt i land. Med henblikk på dette er et avsnitt av siden i bassenget 4 utformet portaktig utløsbart, slik at den aktuelle del av plattformen kan bukseres ut. As mentioned, the form is individually buoyant, but during operation they are firmly connected to each other. The division has the advantage that the individual sections can be separated from each other during assembly, and for major repairs they can be separated and towed individually ashore. For this purpose, a section of the side in the pool 4 is designed to be gate-like and releasable, so that the relevant part of the platform can be pulled out.

Oppfinnelsesgjenstanden er ikke begrenset til den beskrevne utførelse av et naturgasskondensasjonsanlegg. På samme måte lar for-delene ved oppfinnelsen seg utnytte ved anlegg for behandling av an-dre bunnforekomster som utvinnes på eller under havbunnen, da det i praksis er av vesentlig betydning for alle prosessanlegg at funda-mentet forblir horisontalt rettet. The object of the invention is not limited to the described embodiment of a natural gas condensation plant. In the same way, the advantages of the invention can be utilized in facilities for the treatment of other bottom deposits that are mined on or below the seabed, as it is in practice of significant importance for all process facilities that the foundation remains horizontally aligned.
