Description
Foreliggende oppfinnelse vedrører en anordning for oppsamling The present invention relates to a device for collection
av materiale, spesielt hydrokarboner, som utilsiktet strømmer ut ved sjøbunnen, omfattende et traktformet element med åpen bunn holdt i stilling over utslippsområdet, hvilket traktfor- of material, in particular hydrocarbons, which inadvertently flow out at the seabed, comprising a funnel-shaped element with an open bottom held in position over the discharge area, which funnel-
met element er festet til minst én fleksibel rørledning hvis ene ende er forbundet med det nevnte elements indre hulrom og hvis andre ende er forbundet med en lagringsanordning på overflaten som har mulighet til å ta imot det materiale som stiger opp gjennom rørledningen eller -ledningene. said element is attached to at least one flexible pipeline, one end of which is connected to the inner cavity of said element and the other end of which is connected to a storage device on the surface which has the possibility of receiving the material rising through the pipeline or pipes.
En av forurensningskildene i det maritime miljø stammer fra materiale, såsom hovedsakelig hydrokarbonene, som utilsiktet strømmer ut ved sjøbunnen, p.g.a. f.eks. et forlist skip, spesielt et tankskip som ligger på bunnen, og hvorfra hydrokarboner eller kjemisk materiale lekker ut gjennom sprekker og siger opp mot overflaten. Denne forurensningen kan likeledes stamme fra sprekker i en rørledning på sjøbunnen for føring av hydrokarboner, eller også fra et ukontrollert utslipp av hydrokarboner fra et brønnhode i sjøbunnen. One of the sources of pollution in the maritime environment originates from material, such as mainly the hydrocarbons, which unintentionally flow out at the seabed, due to e.g. a sunken ship, especially a tanker lying on the bottom, from which hydrocarbons or chemical material seeps out through cracks and seeps up to the surface. This pollution can also originate from cracks in a pipeline on the seabed for carrying hydrocarbons, or from an uncontrolled release of hydrocarbons from a wellhead in the seabed.
Det har hittil ikke vært mulig å samle opp materiale, spesielt hydrokarboner, som på denne måten er strømmet ut i sjøen. Mange av de hittil foreslåtte løsninger består i at dykkere forsøker å tette igjen lekkasjen i skipet, rørledningen eller brønnhodet. Denne løsningen er kun gjennomførbar der dybden er relativt liten. Until now, it has not been possible to collect material, especially hydrocarbons, which have flowed into the sea in this way. Many of the solutions proposed so far consist of divers trying to plug the leak in the ship, the pipeline or the wellhead. This solution is only feasible where the depth is relatively small.
Den mest benyttede løsning er å la materialet stige opp til overflaten og angripe flakene som danner seg med oppløsende midler. Denne løsningen er ikke tilfredsstillende så lenge den ikke eliminerer forurensningene fullstendig. The most commonly used solution is to let the material rise to the surface and attack the flakes that form with solvents. This solution is not satisfactory as long as it does not completely eliminate the contaminants.
En anordning av den innledningsvis nevnte type er foreslått i US patent nr. 3.500.841. Denne har et stivt, klokkeformet kam-mer som i enden av en slange kan senkes ned over en lekkasje i en rørledning på havbunnen. En dykker må benyttes for å po-sisjonere og feste kammeret. Denne anordning er således kun beregnet for mindre lekkasjer og begrensede dyp. En slik anordning ville være meget vanskelig å benytte på større dyp eller hvor det er tale om større lekkasjemengder, spesielt lekkasje av gass. På grunn av sin stive form ville kammeret lett skjene frem og tilbake under nedsenkningen, og i tilfelle av en gasslekkasje ville den få så vidt stor og uregelmessig oppdrift at den ville være omtrent umulig å få bragt på plass. A device of the initially mentioned type is proposed in US patent no. 3,500,841. This has a rigid, bell-shaped chamber which, at the end of a hose, can be lowered over a leak in a pipeline on the seabed. A diver must be used to position and attach the chamber. This device is therefore only intended for minor leaks and limited depths. Such a device would be very difficult to use at greater depths or where there are large leakage quantities, especially leakage of gas. Because of its rigid shape, the chamber would easily rock back and forth during immersion, and in the event of a gas leak, it would have such a large and irregular buoyancy that it would be almost impossible to get it back into place.
Oppfinnelsen tar sikte på å tilveiebringe en anordning av den innledningsvis nevnte type som ikke er beheftet med ovennevnte ulemper og mangler. Dette oppnås ifølge oppfinnelsen ved at det traktformede element er sammenfoldbart slik at det kan senkes i sammenfoldet tilstand og slås ut på forønskede dyp. The invention aims to provide a device of the initially mentioned type which is not affected by the above-mentioned disadvantages and shortcomings. This is achieved according to the invention by the funnel-shaped element being collapsible so that it can be lowered in the folded state and knocked out to desired depths.
I og med at det traktformede element kan senkes i sammenfoldet tilstand og slås ut på det forønskede dyp, får trakten atskillig mindre vannmotstand under nedsenkningen. Denne kan derved skje hurtigere og uten særlig fare for at trakten skal skjene frem og tilbake i sjøen. I tilfelle av en gasslekkasje, f.eks. en ukontrollert utblåsning i en gassbrønn, vil trakten i sammenfoldet tilstand bli atskillig mindre påvirket av den opp gjennom sjøen ekspanderende gasstrøm. As the funnel-shaped element can be lowered in a folded state and knocked out at the desired depth, the funnel has considerably less water resistance during the immersion. This can thereby happen more quickly and without particular danger of the funnel rolling back and forth into the sea. In the event of a gas leak, e.g. an uncontrolled blowout in a gas well, the funnel in its folded state will be considerably less affected by the gas flow expanding up through the sea.
Anordningen ifølge oppfinnelsen er med fordel utstyrt med en ballasttank på det traktformede element eller på den eller de fleksible rørledningene nær elementet. The device according to the invention is advantageously equipped with a ballast tank on the funnel-shaped element or on the flexible pipeline(s) near the element.
Ved store dyp eller for å øke utslippets stigeevne, kan det være ønskelig å forutse nedsenkede pumpemuligheter, som f.eks. sen-trifugalpumper montert i kaskade, system med innblåsing av luft eller ejektorer montert i en senkkasse som den eller de fleksible rørledningene går gjennom. Senkkassen er montert mellom det traktformede elementet og vannflaten. Pumpeorganene suger opp materiale som er oppsamlet i det traktformede element og trykker dem opp mot overflaten. At great depths or to increase the rising capacity of the discharge, it may be desirable to envisage submerged pumping options, such as e.g. sen-trifugal pumps mounted in cascade, system with blowing in air or ejectors mounted in a sink box through which the flexible pipeline(s) pass. The sump is mounted between the funnel-shaped element and the water surface. The pumping means suck up material collected in the funnel-shaped element and press them up against the surface.
I en foretrukket utforelse har det traktformede element en hylse av et smidig, vanntett stoff, f.eks. en duk av vanntett polyester, polyetylen, neopren eller hvilket som helst vanntett stoff, In a preferred embodiment, the funnel-shaped element has a sleeve of a flexible, waterproof fabric, e.g. a canvas of waterproof polyester, polyethylene, neoprene or any waterproof fabric,
eller stoff som er gjort vanntett og behandlet for å motstå sjo-vann, hydrokarboner eller annet materiale som kan heves, likeledes angrep fra marin flora. or fabric made waterproof and treated to resist sea water, hydrocarbons or other material that can rise, as well as attack by marine flora.
I denne utforelse har det traktformede elementet et antall stenger med beslag slik at de kan slåes ut. Stengene stråler ut fra det punktet der elementet er festet til rorledningen eller -ledningene. Det er fordelaktig at stengenes ytre ender er koblet sammen ved hjelp av et boylig, periferik organ. Elementet har dertil et antall flottorer og låseanordninger som kan utloses for å holde elementet i sammenfoldet stilling under nedsenkningen. Låseanordningene utloses når det sammenfoldete elementet når ned til den bnskede dybde, hvilket frigjor stengene og gjor det mulig å slå disse og hylsen av smidig stoff ut ved påvirkning av flottorene. Hylsens åpningsbevegelse blir stoppet når det perife-riske organet er utstrukket. Anordningen ifolge- oppfinnelsen er dermed i operativ stilling. In this embodiment, the funnel-shaped element has a number of rods with fittings so that they can be knocked out. The bars radiate from the point where the element is attached to the rudder line or lines. It is advantageous that the outer ends of the rods are connected by means of a flexible, peripheral member. The element also has a number of floats and locking devices that can be released to keep the element in a folded position during immersion. The locking devices are released when the folded element reaches the desired depth, which releases the rods and makes it possible to knock them and the sleeve of flexible fabric out by the action of the floats. The opening movement of the sleeve is stopped when the peripheral organ is extended. The device according to the invention is thus in an operational position.
Andre av oppfinnelsens fordeler og karakteristiske egenskaper Other advantages and characteristic features of the invention
vil klarlegges av påfolgende beskrivelse med henvisning til vedlagte tegning av et utforelseseksempel som dog ikke på noen måte er begrensende, der: Figur 1 viser skjematisk anordningen ifolge oppfinnelsen i operativ stilling. Figur 2 viser skjematisk anordningen ifolge oppfinnelsen under nedsenkning. will be made clear by the following description with reference to the attached drawing of an exemplary embodiment which, however, is not limiting in any way, where: Figure 1 schematically shows the device according to the invention in operative position. Figure 2 schematically shows the device according to the invention during immersion.
På figur 1 er det vist et eksempel på utnyttelse av anordningen ifolge oppfinnelsen, som sikrer heving til overflaten av hydrokarboner som lekker ut av et tankskip 1 som er sunket etter et forlis, og ligger på sjobunnen. Figure 1 shows an example of the utilization of the device according to the invention, which ensures the raising to the surface of hydrocarbons leaking out of a tanker 1 which has sunk after a shipwreck and is lying on the seabed.
Anordningen ifolge oppfinnelsen har et traktformet element 2, som består av en hylse av smidig, vanntett stoff 3, f.eks. en polyesterduk, og et antall divergerende stenger 4, i et lett materiale/ så som en aluminiumsleggering, f.eks. duraluminum eller et plastmateriale som er motstandsdyktig mot angrep av hydrokarboner og påvirkningen av det maritime miljoet ved de dyp bruken er forutsatt. Stengene 4 har hver en lengde av storrelsesorden f.eks. 25 m. The device according to the invention has a funnel-shaped element 2, which consists of a sleeve of flexible, waterproof fabric 3, e.g. a polyester cloth, and a number of diverging rods 4, in a light material/ such as an aluminum laying ring, e.g. duraluminum or a plastic material that is resistant to attack by hydrocarbons and the influence of the maritime environment in the deep uses is assumed. The rods 4 each have a length of the order of magnitude, e.g. 25 m.
Stengene er i en av endene sammenbundet ved hjelp av et boylig organ, f.eks. en wire 5. The rods are joined at one of the ends by means of a flexible body, e.g. a wire 5.
Det traktformede element 2 har også flere flottorer 6. The funnel-shaped element 2 also has several floats 6.
Det traktformede element 2 er festet til enden av en fleksibel rorledning 7 som forbinder elementets 2 indre hulrom som er begrenset av hylsen 3, med lagringsmuligheter for hydrokarboner på overflaten arrangert f.eks. ombord i et tankskip 8. Tankskipet 8 er utstyrt med en motordrevet vinsj 9 som kan rulle ut eller inn den fleksible rorledningen 7, til hvis nedre ende det traktformede element 2 er festet. Vinsjen 9 er arrangert på kjent måte og slik at den fleksible rorledningens 7 ende går inn i vinsjens trommel som er tilpasset slik at den er forbundet til skipets bronn ved et foringsror 10 på skipet. Roterende tetningsanordninger (ikke vist) er forutsatt ved kob-lingspunktet mellom foringsroret 10 og vinsjens 9 trommel. The funnel-shaped element 2 is attached to the end of a flexible conduit 7 which connects the inner cavity of the element 2 which is limited by the sleeve 3, with storage possibilities for hydrocarbons on the surface arranged e.g. on board a tanker 8. The tanker 8 is equipped with a motor-driven winch 9 which can roll out or in the flexible rudder line 7, to the lower end of which the funnel-shaped element 2 is attached. The winch 9 is arranged in a known manner and so that the end of the flexible rudder line 7 goes into the winch's drum, which is adapted so that it is connected to the ship's well by a liner rudder 10 on the ship. Rotating sealing devices (not shown) are provided at the connection point between the liner rudder 10 and the winch's 9 drum.
Det kan med fordel monteres avtappingsmuligheter, skjematisk vist ved en ventil 11, på foringsroret 10. Draining facilities can advantageously be mounted, schematically shown by a valve 11, on the liner 10.
Anordningen ifolge oppfinnelsen kan med fordel ha en ballasttank 12, og i påkomne tilfeller, en senkkasse 13 montert på den fleksible rorledningen. Senkkassen 13 inneholder pumpemuligheter for å akselerere heving av materiale oppsamlet i det traktformede element 2 og for å skyve disse opp mot skipet 8 på overflaten. Denne senkkassen 13 blir senket og hevet ved hjelp av konvensjonelle metoder, som f.eks. en kran, montert på skipet 8. Disse "hevingsanordningene benyttes likeledes til å senke og heve det traktformede element 2 i sammenfoldet stilling opp til skipet. The device according to the invention can advantageously have a ballast tank 12, and in appropriate cases, a lowering box 13 mounted on the flexible rudder line. The sinking box 13 contains pumping facilities to accelerate the raising of material collected in the funnel-shaped element 2 and to push these up towards the ship 8 on the surface. This lowering box 13 is lowered and raised using conventional methods, such as e.g. a crane, mounted on the ship 8. These "lifting devices are likewise used to lower and raise the funnel-shaped element 2 in the folded position up to the ship.
På figur 2 er anordningen ifolge oppfinnelsen vist skjematisk under nedsenkningen. Stengene 4 og hylsen 3 er foldet sammen og befinner seg tydelig i den fleksible rorledningens 7 for-lengelse. De er fastlåst i sammenfoldet stilling ved hjelp av en klave 14 som åpnes automatisk eller kan styres fra overflateskipet når elementet 2 når den onskede dybde. Så snart klaven 14 åpner seg, blir stengene 4 og hylsen 3 foldet ut til operativ stilling, som vist i figur 1, ved hjelp av flottorene 6. Det traktformede elements 2 maksimale åpning er nådd når forbindelses-organet 5 er utspent. Lengden av dette organet er bestemt slik at det traktformede element 2 har en åpningsvinkel av størrel-sesorden f.eks. 120°. Figure 2 shows the device according to the invention schematically during the immersion. The rods 4 and the sleeve 3 are folded together and are clearly located in the extension of the flexible rudder line 7. They are locked in the folded position by means of a claw 14 which opens automatically or can be controlled from the surface ship when the element 2 reaches the desired depth. As soon as the claw 14 opens, the rods 4 and the sleeve 3 are unfolded to the operative position, as shown in Figure 1, by means of the floats 6. The maximum opening of the funnel-shaped element 2 is reached when the connecting member 5 is extended. The length of this body is determined so that the funnel-shaped element 2 has an opening angle of the order of magnitude, e.g. 120°.
Når elementet 2 er i utslått stilling over området med hydrokar-bonutslipp, dvs. som vist i eksemplet over lekkasjestedene på When element 2 is in the extended position above the area with hydrocarbon emissions, i.e. as shown in the example of the leakage locations on
det forliste skipet, eller i andre tilfeller over den odelagte rorledning eller over bronnhodet, siger hydrokarbonene opp mot skipet 8 som befinner seg på overflaten. Dette kan med fordel være utstyrt med muligheter for separering, slik at de hevede hydrokarbonene kan gjenvinnes fra sjovannet som uungåelig stiger opp sammen med dem. Overflateskipet er utstyrt med konvensjonelle midler for å merke og lokalisere vraket, så som sonar, fjernsyn osv. For å sikre at anordningen holder seg over området med hydrokarbon-utslipp, kan overflateski^t 8 være utstyrt med kjent apparatur for dynamisk posisjonering som gjor-det mulig å holde det på plass over vraket 1, uansett under hvilke forhold skipet 8 befinner seg. the sunken ship, or in other cases over the broken rudder line or over the wellhead, the hydrocarbons seep up towards the ship 8 which is on the surface. This can advantageously be equipped with possibilities for separation, so that the raised hydrocarbons can be recovered from the seawater that inevitably rises together with them. The surface ship is equipped with conventional means to mark and locate the wreck, such as sonar, television, etc. To ensure that the device stays above the area of hydrocarbon spills, the surface ship 8 can be equipped with known apparatus for dynamic positioning which makes it is possible to keep it in place above the wreck 1, regardless of the conditions under which the ship 8 is located.
Selv om oppfinnelsen er beskrevet i forbindelse med en foretrukket utforelse, er det helt klart at denne ikke er begrensende og at den kan modifiseres etter onske, spesielt hva angår form og materialer, uten å falle utenom oppfinnelsens ramme og ide. Although the invention is described in connection with a preferred embodiment, it is quite clear that this is not limiting and that it can be modified as desired, especially with regard to form and materials, without falling outside the scope and idea of the invention.
Selv om utforelsen vist på tegningen bare benytter en eneste fleksibel rorledning, er det spesielt mulig å gjore bruk av flere slike ledninger som forbindelsesledd mellom det sunkede skipet og skipet på overflaten. Although the embodiment shown in the drawing only uses a single flexible rudder line, it is particularly possible to use several such lines as connecting links between the sunken ship and the ship on the surface.
På tilsvarende måte er det mulig, uten å gå utover oppfinnelsens ramme, å anvende andre metoder for å folde ut det traktformede element 2«In a similar way, it is possible, without going beyond the scope of the invention, to use other methods to unfold the funnel-shaped element 2"
