Abstract
Kombinert lagertank og produksjonsplattform for oljeutvinning i havområder.Combined storage tank and production platform for oil extraction in sea areas.
Description
Oppfinnelsen angår en kombinert lagertank og produksjonsplattform for oljeutvinning i havområder, sammensatt av et antall i dokk fremstilte spennbetongbeholdere som flytende i sjøen er forbundet radialt o.g. aksialt i .hvor .den øvre flate av enkelte av de øverste beholdere er forsynt med en hulsøyle med vesentlig mindre tverrsnittsareal enn beholderens og som oventil tilsammen bærer en plattform, og hvor bunnen i hver nederste beholder og topplaten i hver øverste beholder har form av en polygon, fortrinnsvis en sekskantet plate, som rager ut over omkretsen av selve beholderen, og de polygone plater er forbundet med hverandre ved hjelp av spennbolter som er forankret i beholderbunnen resp. -toppen. The invention relates to a combined storage tank and production platform for oil extraction in sea areas, composed of a number of dock-produced prestressed concrete containers which floating in the sea are connected radially, etc. axially in .where .the upper surface of some of the uppermost containers is provided with a hollow column with a significantly smaller cross-sectional area than that of the container and which together carries a platform at the top, and where the bottom in each lowermost container and the top plate in each uppermost container have the shape of a polygon, preferably a hexagonal plate, which protrudes above the circumference of the container itself, and the polygonal plates are connected to each other by means of tension bolts which are anchored in the container bottom or - the peak.
Ved nedsenkende lagertanker av denne art er det ønskelig å oppnå en mest mulig stiv og jevnt tungt belastet såle av hensyn til bølgebevegelser i sjøen. Videre er denne stivhet ønskelig ved flytting til et annet sted. In the case of submersible storage tanks of this type, it is desirable to achieve the most rigid and uniformly heavily loaded sole possible due to wave movements in the sea. Furthermore, this rigidity is desirable when moving to another location.
Fra norsk patentsøknad nr. 3132/70 og norsk patentskrift nr. 131.179 er det kjent å sammenkople slike beholdere ved hjelp av parallelle spennkabler som ligger forholdsvis ube-skyttet og det gjør også selve koplingssonen. From Norwegian patent application no. 3132/70 and Norwegian patent document no. 131,179 it is known to connect such containers by means of parallel tension cables which lie relatively unprotected and so does the connection zone itself.
Fra norsk patentskrift nr; 132.106 er det kjent å anvende skråstilte spennorganer som krysser hverandre i vertikale koplingssoner som fylles ut med betong. From Norwegian patent document no; 132,106, it is known to use inclined tension members that cross each other in vertical connection zones that are filled with concrete.
Fra fransk patentskrift nr. 1.5^7-704 er det kjent å kople sammen beholderne slik at bunn- og toppflatene i beholderne danner et samlet bunn- og toppflate for den sammenkoplede enhet. From French patent document No. 1.5^7-704, it is known to connect the containers so that the bottom and top surfaces of the containers form a combined bottom and top surface for the connected unit.
Hensikten med oppfinnelsen er til forskjell fra den kjente teknikk, å kople beholderne sammen med vertikale koplingssoner mellom tre tilhverandre grensende beholdere slik at disse sammen med beholdernes begrensningsvegger mellom disse koplingssoner danner innelukkede hulrom som kan tjene til å oppta ballastmateriale. The purpose of the invention, in contrast to the known technique, is to connect the containers together with vertical connection zones between three adjacent containers so that these, together with the container's boundary walls between these connection zones, form enclosed cavities which can serve to accommodate ballast material.
Hensikten med oppfinnelsen er derfor å tilveie-bringe en bedre utforming og sammenkopling av beholderne og bedre muligheter for stabil belastning av hele tanken. The purpose of the invention is therefore to provide a better design and interconnection of the containers and better possibilities for stable loading of the entire tank.
Dette oppnås ifølge oppfinnelsen ved at det i According to the invention, this is achieved by i
det område der spennboltene krysser delelinjen mellom to med hverandre forbundne beholdere, er anordnet en fordypning i platene i hvilken spennboltenes ender er frilagt. og endene av to motsvarende spennbolter er forbundet med hverandre og spent, idet det mellom to overfor hverandre beliggende beholdervegger dannes et mellomrom, i hvilket det fra beholderveggene rager ut hverandre overlappende horisontale forløpende armer-ingsstålbøyler, gjennom hvilke er anbragt et vertikalt for-bindelsesrør, og at de nevnte bøyler og røret er støpt inn i betong ved hjelp av forskaling som er anordnet mellom motstående beholdervegger i koplingssonen, og fordypningen også gjenstøpes, idet det mellom de derved dannede vertikale koplingssoner for tre med hverandre koplede beholdere er dannet et hulrom. the area where the tension bolts cross the parting line between two interconnected containers, a recess is arranged in the plates in which the ends of the tension bolts are exposed. and the ends of two corresponding tension bolts are connected to each other and tensioned, as a space is formed between two container walls situated opposite each other, in which overlapping horizontal continuous reinforcing steel hoops protrude from the container walls, through which a vertical connecting pipe is placed, and that the aforementioned hoops and the pipe are cast into concrete by means of formwork which is arranged between opposite container walls in the connection zone, and the recess is also recast, as a cavity is formed between the thereby formed vertical connection zones for three interconnected containers.
Fortrinnsvis er de nevnte hulrom gjort tilgjenge-lige gjennom en åpning i topplatene, slik at det kan utnyttes for fylling med ballast. Preferably, the mentioned cavities are made accessible through an opening in the top plates, so that it can be used for filling with ballast.
For fordeling av påkjenningene ved nedsenking av tanken og flytting av tanken hvorved den også må bringes i flyte- eller svevetilstand i vannet, er det fordelaktig at den er sammensatt av beholdere i minst to plan, slik at mellom-gulv som dannes av toppen av en under liggende beholder og bunnen i en over liggende beholder, eventuelt den hule søyle tjener til fordeling av ballstvann og trykkluft. For the distribution of the stresses when immersing the tank and moving the tank, whereby it must also be brought into a floating or floating state in the water, it is advantageous that it is composed of containers in at least two levels, so that the intermediate floor formed by the top of a below the horizontal container and the bottom in an overhead container, possibly the hollow column serves for distribution of ballast water and compressed air.
Et utførelseseksempel på oppfinnelsen skal for-klares nærmere under henvisning til tegningene. An embodiment of the invention will be explained in more detail with reference to the drawings.

Utførelseseksempelet viser syv beholdere 1 av spennbetong som er fremstillet i dokk og sjøsatt og sammenkop-let radialt og aksialt i flytende tilstand. Bunnen 4 og toppen 5 av beholderne er sekskantet og rager noe ut over den sirkelformede beholdervegg. På den sentrale og annen hver en avde øvrige seks beholdere er montert en hul søyle 2 med betydelig mindre tverrsnittsareal enn beholdernes og disse søyler bærer en felles trekantet plattform.3• Beholderveggene er forsynt med vertikale koplingssoner 6 og på hver side av disse er to og to til hverandre grensende bunnplater resp. topplater forbundet med hverandre ved hjelp av spennorganer 7 som er forankret i bunnen resp. toppen og som forbindes ved hjelp av spennmidler 12 i en fordypning 11 i bunnen resp. toppen. Derved dannes det mellom koplingssonene 6 i to beholdere som skal sammenkoples en avstand. Koplingssonene 6 er forsynt med et antall horisontalt forløpende armeringsbøyler 8 som på to og to beholdere som skal forbindes med hverandre rager overlappende ut fra koplingssonene. Gjennom bøylene 8 er før+t vertikale stålrør 9 som låser bøylene sammen. På begge sider av koplingssonene 6 anbringes forskaling 10 som under mellomlag av pakninger spennes mot hverandre ved lange skruebolter. Deretter støpes det betong i det forskalede mellomrom. Fordypningene 11 støpes også igjen etter spenning-en av spennmidlene 12. I topplatene og eventuelle bunnplater som a? forbundet med en topplate i en underliggende beholder er anordnet utsparinger 13 for ifylling av ballast i f orm av stein eller sand. Mellom de øvre beholdere kan det anordnes rørforbindelser 14 for olje- eller gassinntak eller -uttak. The design example shows seven containers 1 of prestressed concrete which are manufactured in a dock and launched and connected radially and axially in a liquid state. The bottom 4 and top 5 of the containers are hexagonal and protrude somewhat above the circular container wall. A hollow column 2 with a significantly smaller cross-sectional area than that of the containers is mounted on the central and every other one of the other six containers and these columns carry a common triangular platform.3• The container walls are provided with vertical connection zones 6 and on each side of these are two and two adjacent bottom plates resp. top plates connected to each other by means of tensioning means 7 which are anchored in the bottom or the top and which are connected by means of clamping means 12 in a recess 11 in the bottom resp. the top. Thereby, a distance is formed between the connection zones 6 in two containers that are to be connected. The coupling zones 6 are provided with a number of horizontally extending reinforcing bars 8 which, on two and two containers to be connected to each other, protrude overlappingly from the coupling zones. Through the hoops 8 are before+t vertical steel tubes 9 which lock the hoops together. Formwork 10 is placed on both sides of the connection zones 6, which are clamped against each other by means of long screw bolts under intermediate layers of gaskets. Concrete is then poured into the precast space. The depressions 11 are also molded again after tensioning by the tensioning means 12. In the top plates and any bottom plates such as a? connected to a top plate in an underlying container, recesses 13 are arranged for filling in ballast in the form of stone or sand. Pipe connections 14 for oil or gas intake or outlet can be arranged between the upper containers.
På plattformen 3 kan anordnes boreplattformer 15 som rager On the platform 3, drilling platforms 15 can be arranged which protrude
ut over beholderne, samt kraner 16. Plattformen 3 kan videre utstyres med helikopterplattform. over the containers, as well as cranes 16. Platform 3 can also be equipped with a helicopter platform.
