Description

Foreliggende oppfinnelse vedrorer en anordning for oppsamling av olje e.l. på vann, omfattende en stort sett horisontalt forlopende pose for sleping ved hjelp av minst ett fartoy med minst ett oljelenseparti derimellom som fra posen forloper på skrå utover og forover i sleperetningen, hvilken pose er forsynt med minst en innlopsåpning.som vender forover i sleperetningen og utlop for utpumpning av oppsamlet materiale, samt minst ett flytelegeme festet til posens overside. The present invention relates to a device for collecting oil etc. on water, comprising a generally horizontally extending bag for towing by means of at least one vessel with at least one oil bilge section in between which extends from the bag obliquely outwards and forwards in the towing direction, which bag is provided with at least one inlet opening.facing forward in the towing direction and outlet for pumping out collected material, as well as at least one float attached to the top of the bag.

De oljetahkskipsforlis som hittil er skjedd, har fullt ut vist at dé herav folgende oljeforurensninger ikke kan unn-gåes med det utstyr man rår over idag. Således må det forventes at totalforlis av supertankere med oljelast eller tilfeller av ukontrollerte utblåsninger fra oljebronner, The shipwrecks of oil tankers that have occurred so far have fully shown that the resulting oil pollution cannot be avoided with the equipment available today. Thus, it must be expected that total sinking of supertankers with oil cargo or cases of uncontrolled blowouts from oil wells,

som ikke kan utelukkes, vil kunne medfore meget store olje-lekkasjemengder over lang tid. Foruten at oljeutslipp medforer store okonomiske tap, vil forurensninger p.g.a. olje-lekkasjer kunne medfore uoverskuelige okologiske forstyr-relser for det berorte miljo. which cannot be ruled out, could lead to very large amounts of oil leakage over a long period of time. In addition to the fact that oil spills entail large economic losses, pollution due to oil leaks could cause unforeseeable ecological disturbances for the affected environment.

Oppsamling av olje på vann foregår idag forst og fremst ved hjelp av såkalte oljelenser. Herunder ringe-s den utsolte olje inn ved hjelp av lenser og konsentreres ved sammentrek-ning av lensen slik at oljen kan pumpes opp, f.eks. ved hjelp av en såkalt "skimmer". The collection of oil on water today takes place primarily with the help of so-called oil lenses. Underneath, the sunned oil is drawn in by means of bilges and concentrated by contraction of the bilge so that the oil can be pumped up, e.g. using a so-called "skimmer".

Ved storre oljeutslipp, f.eks. ved forlis av store oljetank-skip eller ved ukontrollerte utblåsninger fra offshore oljebronner, Vil ovennevnte fremgangsmåte være praktisk ugjorlig fordi den vil kreve lenser av uhåndterbare dimensjoner. Man har derfor foreslått å slepe en lense, på lignende måte som en slepenot, gjennom resp. mot bevegelsesretningen av et oljeflak for således å oppnå en konsentrasjon av oljen, d.v.s. et tykkere oljeflak, i bukten av lensen for herfra å pumpe oljen til f.eks. et slepefartoy eller et medfolgende tankskip. In case of large oil spills, e.g. in the event of the sinking of large oil tankers or in the event of uncontrolled blowouts from offshore oil wells, the above method will be practically impractical because it will require bilges of unmanageable dimensions. It has therefore been proposed to tow a bilge, in a similar way to a tow seine, through resp. against the direction of movement of an oil slick to thus achieve a concentration of the oil, i.e. a thicker oil film, in the bay of the bilge to pump the oil from here to e.g. a towing vessel or an accompanying tanker.

Forsok har vist at det ved lensens bukt, hvor lensen forloper stort sett på tvers av sleperetningen, vil oppstå en oppstuvningseffekt som medforer turbulens. Turbulensens hovedrotasjonsretning vil være forover fra lensens overkant og nedover, noe som resulterer i at olje lett fores ned under lensens underkant og således unnslipper. Experiments have shown that at the bow of the bilge, where the bilge runs largely across the direction of the tow, there will be an upwelling effect that causes turbulence. The main direction of rotation of the turbulence will be forward from the upper edge of the bilge downwards, which results in oil being easily fed down under the lower edge of the bilge and thus escaping.

Videre har det vært foreslått å feste en kombinert olj'eopp-samlings- og utskillingsanordning til lensen ved dens bukt som den oppstuvede olje/vannblanding presses inn i. Anordningen har en eller flere åpninger i bunnen for utstromning av det fraskilte vann. Både oljeblandingens inn- og gjen-nomstromning i anordningen bevirker trykktap, noe som igjen betinger en viss oppstuvningseffekt både foran og i anordningen. Dette medforer turbulens som igjen lett resulterer i unnslippende olje, spesielt under urolige vær- og bolge-forhold når sannsynligheten for oljeutslipp er storst. Furthermore, it has been proposed to attach a combined oil collection and separation device to the bilge at its bay into which the backed-up oil/water mixture is pressed. The device has one or more openings in the bottom for the outflow of the separated water. Both the flow of the oil mixture into and through the device causes pressure loss, which in turn requires a certain back-up effect both in front of and in the device. This leads to turbulence which in turn easily results in escaping oil, especially during turbulent weather and swell conditions when the probability of oil spills is greatest.

Det har også vært foreslått å benytte trållignende redskap, d.v.s. en traktformet perforert pose, for sleping i over-flatestilling. Trålposen er gjerne tenkt forsynt med en olje-utskiller i enden som er perforert i bunnen for utslipp av vann, eller trålposen forutsettes fremstilt av et materiale som er gjennomtrengelig for vann, men ikke for olje. Som eksempel på sistnevnte type materiale har vært foreslått et finmasket nett. Imidlertid vil et finmasket nett når det fuk-tes av olje ha en tendens til å bli ugjennomtrengelig for vann fordi vannets sterke'overflatespenning lett forer til dråpedannelse når vannet p.g.a. oljen ikke lenger kan fukte nettet. Det er således uvisst om det noensinne vil lykkes å fremstille et materiale som har ovennevnte egenskaper i praktisk monn. Ovennevnte redskaper vil derfor medfore fare for utslipp av allerede oppsamlet olje, eller de vil ikke kunne virke efter hensikten. It has also been suggested to use trawl-like gear, i.e. a funnel-shaped perforated bag, for towing in surface position. The trawl bag is preferably provided with an oil separator at the end which is perforated at the bottom for the release of water, or the trawl bag is assumed to be made of a material which is permeable to water, but not to oil. As an example of the latter type of material, a fine mesh net has been proposed. However, a fine-mesh net when moistened with oil will tend to become impermeable to water because the water's strong surface tension easily leads to droplet formation when the water due to the oil can no longer wet the mesh. It is thus uncertain whether it will ever be possible to produce a material that has the above-mentioned properties in practical terms. The above tools will therefore entail the risk of spillage of already collected oil, or they will not be able to work as intended.

Formålet med foreliggende oppfinnelse er å tilveiebringe en anordning av den innledningsvis nevnte type hvor de ulemper og mangler som hefter ved de kjente anordninger er eliminert eller redusert. Dette oppnåes ved en anordning som angitt i hovedkravet. Ytterligere fordelaktige trekk ved oppfinnelsen fremgår av underkravene. The purpose of the present invention is to provide a device of the type mentioned at the outset where the disadvantages and shortcomings associated with the known devices are eliminated or reduced. This is achieved by a device as specified in the main claim. Further advantageous features of the invention appear from the subclaims.

Fig. 7 og 8 viser i fugleperspektiv eksempler på slepemåter som kan benyttes for anordninger ifolge oppfinnelsen. Fig. 7 and 8 show a bird's-eye view of examples of towing methods that can be used for devices according to the invention.

Den på fig. 1-4 viste anordning består hovedsakelig av et poseparti og to lensepartier generelt betegnet med hhv.1 og 2. Posen er fremstilt av tett materiale og begrenses av et topp-parti 3, et bunnparti 4, et endeparti 5 og to sidepartier 6. Posens åpning 7 vender forover i sleperetningen. Ved motsatt ende av: åpningen er posen forsynt med et utlopsror 8. The one in fig. The device shown in 1-4 mainly consists of a bag part and two bilge parts generally denoted by 1 and 2 respectively. The bag is made of dense material and is limited by a top part 3, a bottom part 4, an end part 5 and two side parts 6. The bag's opening 7 faces forward in the towing direction. At the opposite end of: the opening, the bag is provided with an outlet rudder 8.

Lensepartiene 2 er festet til posen 1 ved dennes åpning 7 og rager utover og forover i sleperetningen. Lensepartiene omfatter hver et.flyteelement 9, fortrinnsvis i form av en oppblåsbar slange, et kombinert synke- og. strekkelement 10, f.eks. i form av en kjetting, og et lenseskjort 11 som. forbinder flyteelementet 9 med synke- og strekkelementet 10. Lensepartienes flyteelementer er innbyrdes forbundet ved hjelp av et lignede flyteelement 12 som forloper i overkant av posens 1 åpning 7. Poseåpningens underkant er for-, synt med et kombinert synke- og forsterkningsorgan 13 som hensiktsmessig kan bestå av en forlengelse av elementet 10. The bilge parts 2 are attached to the bag 1 at its opening 7 and project outwards and forwards in the towing direction. The bilge parts each comprise a floating element 9, preferably in the form of an inflatable hose, a combined sinking and tensile element 10, e.g. in the form of a chain, and a bilge shirt 11 which. connects the floating element 9 with the sinking and stretching element 10. The floating elements of the bilge parts are connected to each other by means of a similar floating element 12 which extends above the opening 7 of the bag 1. The lower edge of the bag opening is reinforced with a combined sinking and strengthening member 13 which can suitably consist of an extension of element 10.

Posen 1 er også forsynt med et andre flyteelement 14 som likeledes tar form av en oppblåsbar slange. Denne slange forloper i tilnærmet V-form mellom, de fremre ender av lensepartiene via posens bakre parti. Slangen ligger tildels inne i posen og er festet til dennes topparti 3. Slangens V-form og de forlengelser av posens topp- og bunnpartier som forbinder slangen med posen og lensepartiene, gir anordningen ifolge oppfinnelsen stor styrke og stabilitet uten å redusere dens evne til fleksibelt å folge sjoens bevegelser nevneverdig under sleping. The bag 1 is also provided with a second floating element 14 which likewise takes the form of an inflatable hose. This hose runs in an approximate V-shape between the front ends of the bilge parts via the rear part of the bag. The hose is partially inside the bag and is attached to its top part 3. The V-shape of the hose and the extensions of the top and bottom parts of the bag that connect the hose to the bag and the bilge parts give the device according to the invention great strength and stability without reducing its ability to flexibly to follow the sea's movements significantly during towing.

Anordningen slepes efter slepelinene 15 som danner en forlengelse av flyteelementene 9 og 14 og synke- og strekkele-mentene 10'. Når anordningen slepes av kun ett fartoy, er slepelinene 15 fort til fartoyet via oterbord 16, slik det er vist på fig. 7. Et spesielt fordelaktig slepearrangement for bruk ved oppsamling av store oljemengder er vist på fig. The device is towed along the towing lines 15 which form an extension of the floating elements 9 and 14 and the sinking and stretching elements 10'. When the device is towed by only one vessel, the tow lines 15 are fast to the vessel via otter board 16, as shown in fig. 7. A particularly advantageous towing arrangement for use when collecting large quantities of oil is shown in fig.

8. Her er to anordninger ifolge oppfinnelsen med et av sine 8. Here are two devices according to the invention with one of its own

lensépartier, festet til hver sin side av et tankskip 17 som tar ombord den oppsamlede olje, mens anordningenes andre bilge parts, attached to each side of a tanker 17 which takes on board the collected oil, while the devices' other

lenseparti er forbundet med hvert sitt mindre slepefartoy 18. Tankskipet kan eventuelt biståes direkte av et slepefartoy 19. Herved oppnåes sikker styring av tankskipet ved de lave bilge section is connected to each smaller tow vessel 18. The tanker can possibly be directly assisted by a tow vessel 19. This achieves safe steering of the tanker at the low

hastigheter som slepingén oftest må foregå med.speeds at which the towing usually has to take place.

Fig. 6 viser hvorledes anordningen ifolge oppfinnelsen kan suppleres med ytterligere lenseelementer 20 for å oke opp-fangningskapasiteten når sjo- og værforholdene tillater det. Fig. 6 shows how the device according to the invention can be supplemented with additional bilge elements 20 to increase the capture capacity when sea and weather conditions permit.

Lenseelementenes funksjon er naturligvis å lede den dem imellom oppfangede olje mot åpningen 7 av posen 1. Herunder fortykkes oljeskiktet, idet dets tykkelse umiddelbart foran åpningen 7 i forste rekke er avhengig av skiktets opprinnelige tykkelse og forholdet mellom storste og minste avstand mellom de mot åpningen konvergerende lenseelementer, men også til en viss grad av bl.a. slepehastighet og oljens kinematiske viskositet. Det er klart at åpningens 7 hoyde The function of the bilge elements is, of course, to guide the oil caught between them towards the opening 7 of the bag 1. Below this, the oil layer thickens, as its thickness immediately in front of the opening 7 is primarily dependent on the original thickness of the layer and the ratio between the largest and smallest distance between those converging towards the opening bilge elements, but also to a certain extent by i.a. drag speed and the oil's kinematic viscosity. It is clear that the opening's 7 height

må være minst like stor som oljeskiktets tykkelse på dette sted. Imidlertid bor åpningen ikke være så hoy at en ufor-holdsmessig stor andel vann opptaes i posen. Dette er dog ikke til å unngå ved de vanlige trålaktige poser fordi disse vil ha en naturlig tendens til å innta en rund fasong og dermed sope med seg mye vann i underkant. must be at least as large as the thickness of the oil layer at this location. However, the opening should not be so high that a disproportionately large proportion of water is taken up in the bag. However, this cannot be avoided with the usual trawl-like bags because these will have a natural tendency to adopt a round shape and thus sweep up a lot of water at the bottom.

Ifolge oppfinnelsen har man derfor funnet det fordelaktig å forsyne posen med midler som holder posens 1 åpning 7 så godt som jevnt hoy i hele dens bredde uten samtidig å gjore åpningen så formstiv at den ikke kan folge sjoens, resp. oljens bevegelser. Dette er ifolge oppfinnelsen oppnådd ved å anordne strekkopptagende organer ved posens åpning, resp. innlop mellom posens topparti 3 og bunnparti 4. I According to the invention, it has therefore been found advantageous to provide the bag with means that keep the opening 7 of the bag 1 almost uniformly high throughout its width without at the same time making the opening so rigid that it cannot follow the sea, resp. the movements of the oil. According to the invention, this is achieved by arranging strain-absorbing organs at the opening of the bag, resp. inlet between the bag's top part 3 and bottom part 4. I

det på figurene 1-4 viste utforelseseksempel tar disse organer form av kjettinglenker 21 som i nedkant er festet til synke- og forsterkningsorganet 13 og i overkant er festet til flyteelementet 12. I en spesiell fordelaktig utforelse ifolge oppfinnelsen er de strekkopptagende organer fort gjennom roraktige.fbringer 22 som forloper stort sett vertikalt gjennom flyteelementet 12. Herved blir det mulig å justere åpningens 7 hoyde ganske enkelt ved å hale opp, resp. gi ut en passende lengde av strekkorganene gjennom foringene og derefter blokkere strekkorganene på flytelementets overside. in the embodiment shown in Figures 1-4, these bodies take the form of chain links 21 which are attached to the sinking and strengthening member 13 at the bottom and are attached to the floating element 12 at the top. In a particularly advantageous embodiment according to the invention, the strain-absorbing members are row-like. fbringer 22 which runs mostly vertically through the floating element 12. This makes it possible to adjust the height of the opening 7 simply by pulling up, resp. issue a suitable length of tension members through the bushings and then block the tension members on the upper side of the floating element.

En slik justering kan om onsket foretaes mens anordningenSuch an adjustment can, if desired, be made while the device is in use

er i bruk.is in use.

For å sikre mest mulig stabil form på posens 1 åpning 7 erTo ensure the most stable shape of the bag 1 opening 7 is

det funnet onskelig å forhindre også posepartiet nærmest åpningen fra å innta rund fasong. Dette er oppnådd ifolge oppfinnelsen ved å anordne strekkopptagende organer i det nærmeste parti av posen som strekker seg bakover.fra,åpningen. I de viste utforelseseksempler har disse organer, form av stort sett vertikale skillevegger eller skott 23 som er festet til posens ovre og nedre partier 3, 4 og forloper i dennes lengderetning fra åpningen 7 bakover ca. halvvegs til utlopet 8. Skottene er med fordel utferdiget av samme tette materiale som posen, mens de kan om nodvendig også it was found desirable to also prevent the portion of the bag closest to the opening from assuming a round shape. This has been achieved according to the invention by arranging strain-absorbing members in the nearest part of the bag which extends backwards from the opening. In the examples shown, these organs have the form of largely vertical partitions or bulkheads 23 which are attached to the bag's upper and lower parts 3, 4 and extend in its longitudinal direction from the opening 7 backwards approx. halfway to the outlet 8. The bulkheads are preferably made of the same tight material as the bag, while if necessary they can also

bestå av nettaktig eller annet egnet perforert materiale.consist of mesh or other suitable perforated material.

I og med at posen 1 består av tett materiale, vil turbulens som måtte oppstå inne i denne ikke resultere i at olje unnslipper. Fordi posens vegger er tette vil all væske som strommer inn gjennom åpningen 7 bli å pumpe ut gjennom utlopet 8.. Dermed vil det være lett å justere utpumpningskapa-siteten slik at man får en viss innsugningseffekt og således minimaliserer oppstuvning og turbulens foran åpningen. As the bag 1 consists of dense material, turbulence that may occur inside this will not result in oil escaping. Because the bag's walls are tight, all liquid that flows in through the opening 7 will be pumped out through the outlet 8. Thus, it will be easy to adjust the pumping capacity so that you get a certain suction effect and thus minimize back-up and turbulence in front of the opening.

Ved oljeutslipp som skjer langt til havs eller som av andre grunner ikke straks kan samles opp, vil de flyktigere bestand-deler av oljen med tiden fordampe mens de resterende bestand-deler, bl.a. på grunn av bolgepåvirkning, forventes å danne klumper. Disse klumper vil til dels være såvidt store at de ikke kan pumpes med de typer pumper som er praktisk anvend-bare ved angjeldende oljeoppsamlingsanordninger. In the case of oil spills that occur far out to sea or that for other reasons cannot be collected immediately, the more volatile constituents of the oil will eventually evaporate while the remaining constituents, i.a. due to wave action, lumps are expected to form. These lumps will in part be so large that they cannot be pumped with the types of pumps that are practically applicable to the relevant oil collection devices.

For å gjore anordningen ifolge oppfinnelsen anvendbar ogsåTo make the device according to the invention also applicable

for oljesol som har inntatt klumpform, foreslåes det å forsyne, denne motstående åpningen med midler for frigjorbar befestigelse av en ytterligere samlepose 24 som vist på fig.. 5. Festemidlene utgjores her av en flens 25 med et U-formet for oil sol that has taken the form of a lump, it is proposed to supply this opposite opening with means for releasably attaching a further collection bag 24 as shown in fig. 5. The attachment means are here made up of a flange 25 with a U-shaped

spor som en tilsvarende flens på samleposen 24 kan skyvesgroove into which a corresponding flange on the collection bag 24 can be pushed

inn og fastholdes i. Når anordningen benyttes uten samlepose, kan en plate av samme omriss som samleposens flens skyves inn i det U-formede spor og således lukke posen 1 bakentil. Samleposen 24 er i det minste i endepartiet forsynt med perforering 26 for å tillate gjennomstrømning av det vann som forer oljeklumpene inn i samleposen. Sistnevnte kan hensiktsmessig forsynes med en lukkeanordning for bruk under håndtering i fylt tilstand innen tomning kan finne sted. when the device is used without a collection bag, a plate of the same outline as the collection bag's flange can be pushed into the U-shaped groove and thus close the bag 1 at the back. The collection bag 24 is at least in the end part provided with perforation 26 to allow the flow of the water which feeds the oil lumps into the collection bag. The latter can suitably be provided with a closing device for use during handling in a filled state before emptying can take place.
