Description

O ppfinnelsens område The field of the invention

Den foreliggende oppfinnelse vedrører et fartøy med tanker som omskiftbart kan transportere LPG, kondensat og C02, og et system for energiproduksjon uten utslipp av CO2 til atmosfæren The present invention relates to a vessel with tanks that can interchangeably transport LPG, condensate and C02, and a system for energy production without emission of CO2 into the atmosphere

Oppfinnelsens bakgrunn The background of the invention

Den foreliggende oppfinnelse er særlig aktuell i forhold til to problemstillinger: 1. Utslipp til atmosfæren av CO2 er en problemstilling som har økende aktualitet, særlig på grunn av forpliktelser i henhold til Kyoto-avtalen. I forbindelse med bestrebelsene for å redusere utslipp av gasser som bidrar til økt drivhuseffekt, har Norge forpliktet seg til å redusere utslippene av CO2 med ca. 12 millioner tonn i forhold til det forventede utslippsnivå i år 2010 dersom tiltak ikke iverksettes. En meget aktuell metode for å redusere C02-utslipp er å deponere CO2 i undergrunnsreservoarer hvorfra hydrokarboner produseres, hvorved det injiserte C02 kan bidra til opprettholdelse av reservoartrykket for fortsatt utvinning av hydrokarboner. Nevnte C02 injiseres i væskeform eller i gassform, hvorav injeksjon i gassform foregår i dag. Idéen med å injisere C02 i væskeform i undergrunnsreservoarer er kjent, og er planlagt på Søhvitfeltet utenfor Nord-Norge fra år 2005. Etter inngåelse av Kyoto-avtalen er både utslipp og deponering av CO2 blitt en handelsvare som kan kjøpes og selges mellom industriaktører og nasjoner. I Norge er det planlagt bygging av flere gasskraftverk. Utslippene av CO2 fra et gasskraftverk er typisk ca. 2 millioner tonn pr. år, hvilket representerer en avhendingsverdi på ca. 300 millioner NOK. Gasskraftverk og andre store industriaktører er aktuelle leverandører av væskeformig C02. 2. Det finnes gassfelt til havs der det i dag ikke er mulig å produsere de tyngre gassfraksjoner, slik at de tyngre gassfraksjoner enten må injiseres tilbake i reservoaret der de kom fra eller må avbrennes. Et typisk gassfelt uten løsning for å produsere de tyngre gassfraksjoner kan i dag bidra med en døgnproduksjon på ca. 1000 tonn LPG, i tillegg til kondensat. Utnyttelse av de tyngre gassfraksjoner fra 4-5 typiske gassfelt vil representere en markedsverdi på ca. 3,5 milliarder NOK pr. år. The present invention is particularly relevant in relation to two issues: 1. Emission of CO2 into the atmosphere is an issue that is of increasing relevance, particularly due to obligations according to the Kyoto agreement. In connection with efforts to reduce emissions of gases that contribute to an increased greenhouse effect, Norway has undertaken to reduce emissions of CO2 by approx. 12 million tonnes in relation to the expected emission level in 2010 if measures are not taken. A very current method for reducing C02 emissions is to deposit CO2 in underground reservoirs from which hydrocarbons are produced, whereby the injected C02 can contribute to maintaining the reservoir pressure for continued extraction of hydrocarbons. Said C02 is injected in liquid form or in gaseous form, of which injection in gaseous form takes place today. The idea of injecting C02 in liquid form into underground reservoirs is known, and is planned for the Søhvit field outside northern Norway from 2005. After the conclusion of the Kyoto agreement, both emissions and deposition of CO2 have become a commodity that can be bought and sold between industry players and nations . In Norway, the construction of several gas-fired power plants is planned. The emissions of CO2 from a gas power plant are typically approx. 2 million tonnes per year, which represents a disposal value of approx. NOK 300 million. Gas power plants and other large industrial players are current suppliers of liquid C02. 2. There are gas fields offshore where it is not currently possible to produce the heavier gas fractions, so that the heavier gas fractions must either be injected back into the reservoir from which they came or must be burned. A typical gas field without a solution to produce the heavier gas fractions can today contribute with a 24-hour production of approx. 1,000 tonnes of LPG, in addition to condensate. Exploitation of the heavier gas fractions from 4-5 typical gas fields will represent a market value of approx. NOK 3.5 billion per year.

I lys av de ovennevnte problemstillinger foreligger det et transportbehov for å kunne transportere de nevnte tyngre gassfraksjoner (LPG primært, men også noe kondensat) og væskeformig C02. Det er særlig behov for et fartøy som kan frakte de nevnte typer last på én kjøl under full fleksibilitet med hensyn til lastutskifting, hvorved LPG og kondensat kan transporteres en vei og væskeformig CO2 kan transporteres en annen vei. Det er også behov for et fartøy som, i tillegg til de ovennevnte funksjoner, kan tilkobles gassfelt uten løsning for produksjon av tyngre gasskomponenter, slik at fartøyet kan separere ut og laste de tyngre gasskomponenter samtidig som væskeformig C02 losses for påfølgende undergrunnsinjeksjon. In light of the above-mentioned issues, there is a transport need to be able to transport the aforementioned heavier gas fractions (LPG primarily, but also some condensate) and liquid C02. There is a particular need for a vessel that can transport the mentioned types of cargo on one keel with full flexibility with regard to cargo exchange, whereby LPG and condensate can be transported one way and liquid CO2 can be transported another way. There is also a need for a vessel which, in addition to the above-mentioned functions, can be connected to gas fields without a solution for the production of heavier gas components, so that the vessel can separate out and load the heavier gas components at the same time as liquid C02 is unloaded for subsequent underground injection.

Kjent teknikk Known technique

Det finnes i dag kun ett fartøy, eller nærmere bestemt en skrogkonstruksjon, som kan transportere LPG og kondensat på samme kjøl i stor skala, med høy grad av sikkerhet. Det siktes til en skrogkonstruksjon patentsøkt av Navion ASA med norsk patentsøknad NO 2001 1982. Nevnte fartøy har ikke utforming eller utrustning til å transportere væskeformig CO2 i stor skala, og har dessuten ingen separasjonsfasiliteter. There is currently only one vessel, or more specifically a hull structure, that can transport LPG and condensate on the same keel on a large scale, with a high degree of safety. The aim is a hull construction applied for by Navion ASA with Norwegian patent application NO 2001 1982. Said vessel is not designed or equipped to transport liquid CO2 on a large scale, and furthermore has no separation facilities.

Det finnes i dag ingen fartøy for transport av væskeformig C02 i stor skala. There are currently no vessels for transporting liquid C02 on a large scale.

Tegninger Drawings

Det foreligger en tegning som omfatter to figurer, hvor: There is a drawing that includes two figures, where:

Figur 1 illustrerer et fartøy ifølge oppfinnelsen, ved tilkobling til et gassfelt. Figur 2 illustrerer et fartøy ifølge oppfinnelsen, ved tilkobling til et kraftverk. Figure 1 illustrates a vessel according to the invention, when connected to a gas field. Figure 2 illustrates a vessel according to the invention, when connected to a power plant.

Detaljert beskrivelse Detailed description

Det henvises til figurene 1 og 2. Reference is made to figures 1 and 2.

Med den foreliggende oppfinnelse tilveiebringes et fartøy 1, omfattende: utrustning for å laste LPG, én eller flere tanker 2 for stabil lagring av LPG under transport, og utrustning for å losse LPG, With the present invention, a vessel 1 is provided, comprising: equipment for loading LPG, one or more tanks 2 for stable storage of LPG during transport, and equipment for unloading LPG,

utrustning for å laste kondensat eller annen væske som er stabil under atmosfæretrykk, én eller flere tanker 3 for lagring av nevnte kondensat eller væske under transport, og utrustning for å losse nevnte kondensat eller væske, og equipment for loading condensate or other liquid which is stable under atmospheric pressure, one or more tanks 3 for storing said condensate or liquid during transport, and equipment for unloading said condensate or liquid, and

en separasjonsenhet 6 som er i stand til å motta en strøm 7 av våtgass og kondensat for separasjon til LPG, kondensat og tørrgass, slik at LPG og kondensat kan a separation unit 6 capable of receiving a stream 7 of wet gas and condensate for separation into LPG, condensate and dry gas, so that the LPG and condensate can

ledes til respektive tanker 2, 3 i fartøyet og tørrgass 8 kan ledes ut fra fartøyet til en annen enhet. is led to respective tanks 2, 3 in the vessel and dry gas 8 can be led out from the vessel to another unit.

Fartøyet er særpreget ved at det videre omfatter: The vessel is distinctive in that it also includes:

utrustning for å laste væskeformig C02, én eller flere tanker 4 for stabil lagring av væskeformig C02 under transport, og utrustning 5 for å losse væskeformig C02 til en annen enhet, eksempelvis for påfølgende injeksjon i et undergrunnsreservoar. equipment for loading liquid C02, one or more tanks 4 for stable storage of liquid C02 during transport, and equipment 5 for unloading liquid C02 to another unit, for example for subsequent injection into an underground reservoir.

På figur 1 er det illustrert at fartøyet ligger tilkoblet et gassfelt til havs, via en overflateplattform som er uten fasiliteter for produksjon av de tyngre gasskomponenter. Fartøyet laster en strøm 7 omfattende våtgass og kondensat for separasjon av nevnte last i separasjonsenheten til LPG, kondensat og tørrgass. LPG og kondensat lagres på fartøyet i respektive tanker 2,3, hvorved fartøyet lastes med LPG og kondensat. Tørrgassen ledes gjennom en ledning 8 tilbake til overflateplattformen for påfølgende videre transport, eksempelvis gjennom en gassrørledning. Tilkoblingen mot gassfeltet er via en kobling av typen STL- Submerged Turret Loading, et nedsenket dreielegeme for lasting, i henhold til tidligere kjent teknikk. Separasjonsenheten er fortrinnsvis anordnet nær fartøyets tilkobling mot gassfeltet, for å holde kort transportvei. Det er illustrert samtidig lossing av væskeformig C02 via en egen ledning 5. Figur 1 gir således en illustrasjon av fartøyet og dets operasjon i en ende av en transportvei. Figure 1 illustrates that the vessel is connected to an offshore gas field, via a surface platform which has no facilities for the production of the heavier gas components. The vessel loads a stream 7 comprising wet gas and condensate for separation of said cargo in the separation unit into LPG, condensate and dry gas. LPG and condensate are stored on the vessel in respective tanks 2,3, whereby the vessel is loaded with LPG and condensate. The dry gas is led through a line 8 back to the surface platform for subsequent further transport, for example through a gas pipeline. The connection to the gas field is via a connection of the type STL - Submerged Turret Loading, a submerged rotating body for loading, according to previously known technology. The separation unit is preferably arranged near the vessel's connection to the gas field, in order to keep the transport path short. Simultaneous unloading of liquid C02 via a separate line 5 is illustrated. Figure 1 thus provides an illustration of the vessel and its operation at one end of a transport route.

På figur 2 illustreres fartøyet og dets operasjon i en annen ende av transportveien, nærmere bestemt ved et kraftverk der fartøyet laster væskeformig C02 og losser LPG og kondensat. Figure 2 illustrates the vessel and its operation at another end of the transport route, specifically at a power plant where the vessel loads liquid C02 and unloads LPG and condensate.

Ved operasjon av fartøyet i henhold til figurene 1 og 2 blir det oppnådd økt markedsverdi fra gassfeltet ved at også de tyngre gasskomponenter blir produsert, C02 blir deponert således at bidrag blir gitt både til oppfyllelse av Kyoto-avtalens forpliktelser og opprettholdelse av reservoartrykket, og fartøyets operatør kan frakte en verdifull last begge transportveier. When operating the vessel in accordance with figures 1 and 2, increased market value is achieved from the gas field by the fact that the heavier gas components are also produced, C02 is deposited so that a contribution is made both to fulfilling the obligations of the Kyoto agreement and maintaining the reservoir pressure, and the vessel's operator can transport a valuable load both ways.

Med LPG menes det væskedannet petroleumsgass som må nedkjøles til temperatur under normal omgivelsestemperatur og/eller holdes under trykk høyere enn atmosfæretrykket for å foreligge som en stabil væske. By LPG is meant liquefied petroleum gas that must be cooled to a temperature below normal ambient temperature and/or kept under pressure higher than atmospheric pressure in order to exist as a stable liquid.

Med kondensat menes det væskeformige bestanddeler kondensert ut fra gass, og eventuelt mindre mengder andre bestanddeler som i væskeform har vært assosiert med gassen, hvilket kondensat foreligger som en stabil væske ved normal omgivelsestemperatur under atmosfæretrykk. Condensate means liquid components condensed from gas, and possibly smaller amounts of other components that have been associated with the gas in liquid form, which condensate exists as a stable liquid at normal ambient temperature under atmospheric pressure.

Med C02 menes i hovedsak ren C02, i den utstrekning forstyrrende innvirkning av ytterligere bestanddeler unngås. By C02 is essentially meant pure C02, to the extent that the disturbing influence of further components is avoided.

Den generelle utforming av fartøyets skrog er med fordel i henhold til patentpublikasj on NO 2001 1982. Fartøyet har derved dobbelt skrog med et sentralt lasteområde langs fartøyets lengdeakse, mellom to langsgående ytre skott, fortrinnsvis med lastetanker anordnet på rekke sentrert langs lengdeaksen i det sentrale lasteområde, og med sidetanker eller vingtanker symmetrisk mellom nevnte skott og de ytre doble skrogvegger. Fartøyet omfatter derved eksempelvis 8 tanker anbrakt langs skipets senterakse, hvor nevnte tanker har utforming og utrustning som muliggjør enhver av de aktuelle typer last, og tanker for kondensat eller annen væske som er stabil under atmosfæretrykk langs hver av fartøyets sider. Det henvises til ovennevnte patentpublikasj on for ytterligere beskrivelse. The general design of the vessel's hull is advantageously in accordance with patent publication NO 2001 1982. The vessel thus has a double hull with a central loading area along the longitudinal axis of the vessel, between two longitudinal outer bulkheads, preferably with cargo tanks arranged in a row centered along the longitudinal axis in the central loading area , and with side tanks or wing tanks symmetrically between said bulkheads and the outer double hull walls. The vessel thus includes, for example, 8 tanks located along the ship's center axis, where said tanks have a design and equipment that enables any of the relevant types of cargo, and tanks for condensate or other liquid that is stable under atmospheric pressure along each of the vessel's sides. Reference is made to the above-mentioned patent publication for further description.

Det er med fordel opplegg for fluidkommunikasjon mellom tanker, fortrinnsvis med dobbel ventilsegregering. It is advantageous to have arrangements for fluid communication between tanks, preferably with double valve segregation.

Fartøyet kan generelt sett utformes fritt under forutsetning av at funksjonene som skal utøves blir ivaretatt. Tankene kan i prinsippet ha hvilken som helst form og være av hvilket som helst antall, gitt at fartøyets funksjon opprettholdes. The vessel can generally be designed freely, provided that the functions to be performed are taken care of. The tanks can in principle have any shape and be of any number, provided that the function of the vessel is maintained.

Generelt kan kondensattanker dimensjoneres for atmosfæretrykk og atmosfære-temperatur, LPG-tanker kan dimensjoneres for minimum 3 bar driftstrykk og maksimum -30 °C driftstemperatur, mens CCVtanker kan dimensjoneres for minimum 5,3 bar driftstrykk og maksimum -50 °C driftstemperatur. Derved unngås gassdannelse eller tørrisdannelse. In general, condensate tanks can be designed for atmospheric pressure and atmospheric temperature, LPG tanks can be designed for a minimum 3 bar operating pressure and a maximum -30 °C operating temperature, while CCV tanks can be designed for a minimum 5.3 bar operating pressure and a maximum -50 °C operating temperature. This prevents gas formation or dry ice formation.

Alle lastetanker i fartøyet har utforming og utrustning til å opprettholde en lasttemperatur på -50 °C eller lavere og et lasttrykk på minimum 8 bar. Derved kan alle lastetanker i fartøyet i henhold til oppfinnelsen ta alle aktuelle typer last. Tankene er hensiktsmessig utformet med ytre isolasjon over et skall av austenittisk rustfritt stål eller annet materiale som ikke er utsatt for sprøbrudd ved den aktuelle nedkjøling, med en kjølekappe mellom nevnte isolasjon og skall, og eventuelt med kjøleinnretninger inne i tankene. All cargo tanks in the vessel are designed and equipped to maintain a cargo temperature of -50 °C or lower and a cargo pressure of at least 8 bar. Thereby, all cargo tanks in the vessel according to the invention can take all applicable types of cargo. The tanks are appropriately designed with outer insulation over a shell of austenitic stainless steel or other material that is not susceptible to brittle fracture during the relevant cooling, with a cooling jacket between said insulation and shell, and possibly with cooling devices inside the tanks.

I en foretrukken utførelsesform har hver tank påtenkt for enhver aktuell type last form av en sylinder med sirkulært tverrsnitt med en halvkuleformet øvre ende og en halvkuleformet nedre ende, idet hver tank er anordnet stående vertikalt i fartøyet med den øvre ende ovenfor fartøyets dekknivå. Typiske dimensjoner vil være: indre diameter 8-10 m og høyde 15-20 m. En slik tankutforming gir et fordelaktig stort lagringsvolum i forhold til veggtykkelse og vekt av en tank. In a preferred embodiment, each tank has the shape of a cylinder with a circular cross-section with a hemispherical upper end and a hemispherical lower end intended for any relevant type of cargo, each tank being arranged standing vertically in the vessel with the upper end above the vessel's deck level. Typical dimensions will be: inner diameter 8-10 m and height 15-20 m. Such a tank design provides an advantageously large storage volume in relation to the wall thickness and weight of a tank.

I en foretrukken utførelsesform av fartøyet har alle tankene form av en vertikalt stående sylinder med sirkulært tverrsnitt og halvkuleformede ender, idet tankene som ligger i fartøyets lengdeakse strekker seg opp over dekksnivå, mens sidetankene eller vingtankene i sin helhet ligger under dekksnivå og er symmetrisk plassert rundt fartøyets lengdeakse. Derved oppnås stort lastevolum og god stabilitet. In a preferred embodiment of the vessel, all the tanks have the shape of a vertically standing cylinder with a circular cross-section and hemispherical ends, the tanks located in the longitudinal axis of the vessel extending above deck level, while the side tanks or wing tanks in their entirety lie below deck level and are symmetrically placed around longitudinal axis of the vessel. This results in a large load volume and good stability.

Alle typer last foreligger i væskeform og lastes og losses ved hjelp av rørledninger, koblinger, ventiler og pumper. I tankene benyttes det fortrinnsvis senkepumper for å sikre god tømming. Forutsatt at tankene og utrustningen for lasting og lossing har slik utforming at det oppnås god tømming, forventes det ikke spesielle problemer ved skifte fra en type last til en annen type last i en tank. All types of cargo are available in liquid form and are loaded and unloaded using pipelines, couplings, valves and pumps. Submersible pumps are preferably used in the tanks to ensure good emptying. Provided that the tanks and the equipment for loading and unloading are designed in such a way that good emptying is achieved, no particular problems are expected when changing from one type of cargo to another type of cargo in a tank.

Fartøyet har fortrinnsvis to uavhengige kjølesystem eller kjølesløyfer, med kjøling til tanker, eventuelt til utrustning for lasting og lossing, og til separasjonsenheten. For å unngå avgassing eller dannelse av tørris kan det fortrinnsvis utføres forhåndsnedkjøling av laste- og losseutrustning, tanker og separasjonsenhetens kjølende deler, før innføring av LPG eller C02 i tanker og C02 i separasjonsenhetens varmeveksler. The vessel preferably has two independent cooling systems or cooling loops, with cooling for tanks, possibly for equipment for loading and unloading, and for the separation unit. To avoid degassing or the formation of dry ice, pre-cooling of loading and unloading equipment, tanks and the separation unit's cooling parts can preferably be carried out, before introduction of LPG or C02 into tanks and C02 into the separation unit's heat exchanger.

Innløpsstrømmen av våtgass til fartøyet holder et typisk trykk på 200-300 bar og en typisk temperatur på ca. 100 °C. The inlet flow of wet gas to the vessel maintains a typical pressure of 200-300 bar and a typical temperature of approx. 100 °C.

Fartøyets separasjonsenhet har utforming slik at den funksjonerer ved ekspansjon og trykkavlastning i kombinasjon med kjøling. Det er foretrukket at kjølingen helt eller delvis tilveiebringes ved varmeveksling mot relativt kald væskeformig C02 i en C02-strøm som losses til en annen enhet, hvilken væskeformig C02 -strøm som losses foreligger i motstrøm til separasjonsenhetens innløpsstrøm. Dette er indikert på figur 1 ved at C02-strømmen 5 er ledet gjennom en del av separasjonsenheten 6. Det kan anordnes strømningssløyfer av væskeformig C02 for kjøling i tillegg til strømmen som tilveiebringes ved lossing. The vessel's separation unit is designed so that it functions by expansion and pressure relief in combination with cooling. It is preferred that the cooling is provided in whole or in part by heat exchange against relatively cold liquid C02 in a C02 flow that is discharged to another unit, which liquid C02 flow that is discharged is in countercurrent to the separation unit's inlet flow. This is indicated in Figure 1 by the fact that the C02 flow 5 is led through part of the separation unit 6. Flow loops of liquid C02 can be arranged for cooling in addition to the flow provided during unloading.

Det er foretrukket at fartøyets separasjonsenhet inneholder utrustning til temperaturstyrt varmeveksling med væskeformig C02 slik at temperaturen i den væskeformige C02 opprettholdes under en forhåndsbestemt maksimal øvre verdi. Derved kan dannelse av tørris eller C02 -gass i varmeveksleren unngås. It is preferred that the vessel's separation unit contains equipment for temperature-controlled heat exchange with liquid C02 so that the temperature in the liquid C02 is maintained below a predetermined maximum upper value. Thereby, the formation of dry ice or C02 gas in the heat exchanger can be avoided.

For å unngå dannelse av tørris eller C02 -gass i varmeveksleren er det fordelaktig å forhåndsnedkjøle varmeveksleren ved hjelp av kjølesystemet og/eller flytende C02 før innløpsstrømmen til separasjonsenheten gradvis åpnes. To avoid the formation of dry ice or C02 gas in the heat exchanger, it is advantageous to pre-cool the heat exchanger using the cooling system and/or liquid C02 before the inlet flow to the separation unit is gradually opened.

Med den foreliggende oppfinnelse tilveiebringes det også et fartøy som prinsipielt er likt med fartøyet beskrevet ovenfor, bortsett fra at fartøyet er uten en separasjonsenhet. The present invention also provides a vessel which is in principle similar to the vessel described above, except that the vessel is without a separation unit.

Det henvises til figurene, som i tillegg til ytterligere trekk viser trekk for det nevnte fartøy. Reference is made to the figures, which, in addition to further features, show features for the aforementioned vessel.

Det ytterligere fartøy omfatter: The additional vessel includes:

utrustning for å laste LPG, én eller flere tanker 2 for stabil lagring av LPG under transport, og utrustning for å losse LPG, equipment for loading LPG, one or more tanks 2 for stable storage of LPG during transport, and equipment for unloading LPG,

utrustning for å laste kondensat eller annen væske som er stabil under atmosfæretrykk, én eller flere tanker 3 for lagring av nevnte kondensat eller væske under transport, og utrustning for å losse nevnte kondensat eller væske. equipment for loading condensate or other liquid which is stable under atmospheric pressure, one or more tanks 3 for storing said condensate or liquid during transport, and equipment for unloading said condensate or liquid.

Det ytterligere fartøy særpreges ved at det omfatter: The additional vessel is characterized by the fact that it includes:

utrustning for å laste væskeformig C02, én eller flere tanker 4 for stabil lagring av væskeformig C02 under transport, og utrustning 5 for å losse væskeformig C02 til en annen enhet, eksempelvis for påfølgende injeksjon i et undergrunnsreservoar. equipment for loading liquid C02, one or more tanks 4 for stable storage of liquid C02 during transport, and equipment 5 for unloading liquid C02 to another unit, for example for subsequent injection into an underground reservoir.

Det ytterligere fartøy kan ikke tilkobles et gassfelt for å separere ut og laste tunge gasskomponenter som LPG og kondensat, men kan laste LPG, kondensat eller annen væske som er stabil ved atmosfæretrykk der slik last foreligger ferdig separert og klar for utskipning. En aktuell transportvei er å laste væskeformig C02 fra et gasskraftverk, levere nevnte væskeformige C02 ved et LNG-anlegg (eksempelvis Snøhvit) for påfølgende injeksjon i et undergrunnsreservoar, laste LPG og kondensat fra nevnte LNG-anlegg, og levere nevnte LPG og kondensat ved nevnte gasskraftverk eller et annet sted, og på ny laste væskeformig C02 fra gasskraftverket. The additional vessel cannot be connected to a gas field to separate out and load heavy gas components such as LPG and condensate, but can load LPG, condensate or other liquid that is stable at atmospheric pressure where such cargo is fully separated and ready for shipment. A current transport route is to load liquid C02 from a gas power plant, deliver said liquid C02 at an LNG plant (for example Snøhvit) for subsequent injection into an underground reservoir, load LPG and condensate from said LNG plant, and deliver said LPG and condensate at said gas power plant or elsewhere, and re-load liquid C02 from the gas power plant.

Det ytterligere fartøy ifølge oppfinnelsen har samme foretrukne utførelsesformer og fordelaktige trekk som dem beskrevet for det først omtalte fartøy, i den utstrekning fartøyene har sammenfallende utforming. The further vessel according to the invention has the same preferred embodiments and advantageous features as those described for the first mentioned vessel, to the extent that the vessels have a matching design.

Med den foreliggende oppfinnelse tilveiebringes også et system for energiproduksjon uten utslipp av C02 til atmosfæren, omfattende With the present invention, a system for energy production without emission of C02 to the atmosphere is also provided, comprehensively

en eller flere kilder til hydrokarboner, one or more sources of hydrocarbons,

ett eller flere fartøy, og eventuelt andre transportinnretninger, for transport av nevnte hydrokarboner til one or more vessels, and possibly other transport devices, for the transport of said hydrocarbons to

ett eller flere kraftverk hvor energi produseres ved forbrenning av nevnte hydrokarboner, og one or more power plants where energy is produced by burning said hydrocarbons, and

en eller flere kilder til C02 som kan transporteres av de ett eller flere fartøy og eventuelt andre transportinnretninger til one or more sources of C02 that can be transported by the one or more vessels and possibly other transport devices to

ett eller flere mottakssteder for C02 for påfølgende injeksjon av C02 ned i undergrunnen, særpreget ved at det omfatter minst ett av fartøyene ifølge oppfinnelsen. one or more receiving points for C02 for subsequent injection of C02 into the underground, characterized by the fact that it includes at least one of the vessels according to the invention.

Det er fordelaktig om systemets kilde til hydrokarboner og mottaksstedet for C02 for påfølgende injeksjon av C02 ned i undergrunnen, er ett eller flere gassfelt eller dertil knyttede fasiliteter, eksempelvis prosesseringsfasiliteter. Derved oppnås det en kort transportvei ved at lasting av hydrokarboner og lossing av C02 for påfølgende undergrunnsinjeksjon forgår på samme sted, i tillegg til at injeksjon av C02 i gassfeltreservoaret bidrar til opprettholdelse av reservoartrykket. It is advantageous if the system's source of hydrocarbons and the receiving point for C02 for subsequent injection of C02 into the underground are one or more gas fields or related facilities, for example processing facilities. Thereby, a short transport path is achieved by loading of hydrocarbons and unloading of C02 for subsequent underground injection taking place in the same place, in addition to the fact that injection of C02 into the gas field reservoir contributes to maintaining the reservoir pressure.

Der er også fordelaktig om kilden til C02 er forbrenningen ved de ett eller flere kraftverk, naturlig forekommende C02 blant nevnte kilder til hydrokarboner, og eventuelt ytterligere kilder slik som raffinerier og industrianlegg. Det er fordelaktig om C02 foreligger i væskeform før transport, hvorved transportvolumet reduseres. Imidlertid kan C02 både transporteres og injiseres i gassform. Naturlig forekommende C02 blant nevnte kilder til hydrokarboner kan foreligge i blanding med nevnte hydrokarboner, og kan transporteres i blanding med nevnte hydrokarboner. Hydrokarbonene blir deretter forbrent for energiproduksjon i de ett eller flere kraftverk og deretter væskedannes all C02. Dersom C02-innblandingen i hydrokarbonene er meget høy, kan en del C02 separeres ut før nevnte forbrenning eller det kan innblandes ytterligere hydrokarboner. It is also advantageous if the source of C02 is combustion at one or more power plants, naturally occurring C02 among the aforementioned sources of hydrocarbons, and possibly further sources such as refineries and industrial plants. It is advantageous if C02 is available in liquid form before transport, whereby the transport volume is reduced. However, C02 can be both transported and injected in gaseous form. Naturally occurring C02 among said sources of hydrocarbons can be present in a mixture with said hydrocarbons, and can be transported in a mixture with said hydrocarbons. The hydrocarbons are then burned for energy production in one or more power plants and then all C02 is liquefied. If the C02 mixture in the hydrocarbons is very high, some C02 can be separated out before said combustion or further hydrocarbons can be mixed in.

Med systemet ifølge den foreliggende oppfinnelse gjøres det bruk av fartøyene ifølge den foreliggende oppfinnelse, med utførelsesformer slik det er beskrevet ovenfor. With the system according to the present invention, use is made of the vessels according to the present invention, with embodiments as described above.
