Opfindelsen angår et apparat til brug ved fremstilling af en understøtning for en rørledning, der er anbragt frithængende over en bølgeformet havbund, hvilket apparat som udgangsemne for understøtningen omfat-5 ter en udvidelig pude, der er forbundet udløseligt med apparatet under dettes operering, og som er dannet af et hylster, der består af et syntetisk fiberstof med stor styrke, og som har en sadelformet topdel og en rektangulær bunddel, samt hvor apparatet, der er op-10 hængt i et bærekabel, er indrettet til at kunne nedsænkes fra et depotskib til havbunden i nærheden af rørledningen, hvorefter det ved hjælp af et undervandsfartøj, der har en svingbar arbejdsarm, er indrettet til at kunne manøvreres ind til rørledningen for pla-15 cering af puden på det sted under rørledningen, hvor denne skal understøttes, hvorhos apparatet er indrettet til at kunne indsprøjte en flydende hærdebar cement i puden under ledningen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for use in the manufacture of a support for a pipeline disposed freely suspended over a corrugated seabed, which apparatus as a starting material for the support comprises an expandable cushion which is releasably connected to the apparatus during its operation. is formed of a casing consisting of a high-strength synthetic fiber fabric having a saddle-shaped top part and a rectangular bottom part, and wherein the apparatus suspended in a carrier cable is adapted to be submerged from a storage vessel to the seabed near the pipeline, after which it is arranged by means of an underwater vessel having a pivotable working arm to be maneuvered into the pipeline for placement of the pad at the location below the pipeline where it is to be supported, where the apparatus is designed to inject a liquid curable cement into the pad under the conduit.

Med udgangspunkt i denne konstruktion har op-20 findelsen til opgave at angive et nemt betjeneligt apparat af enkel og robust opbygning, som kan operere med en ekstremt god driftsøkonomi på vilkårlige havdybder - herunder store havdybder på 600 meter og mere, og ved hjælp af hvilket der ud fra den præfabri-25 kerede pude kan fremstilles en upåklagelig understøtning for denne på en nem og hurtig måde.Based on this design, the inventor is tasked with specifying an easy-to-operate device of simple and robust construction that can operate with an extremely good operating economy at any depth of sea - including large ocean depths of 600 meters and more, and by means of which an impeccable support can be made from the prefabricated cushion in an easy and fast way.

Til opnåelse heraf er apparatet ifølge opfindelsen ejendommeligt ved, at det omfatter et genindvindeligt betjeningsag-30 gregat, der har tre indsprøjtningssystemer - hver indrettet til indsprøjtning af flydende cement i puden under rørledningen, og som består af et hus, hvori der er båret en med en bunddel udstyret beholder, der har et fleksibelt afgangsrør, og som er udformet til at kunne 35 fyldes med flydende cement.To achieve this, the apparatus according to the invention is peculiar in that it comprises a retrievable operating assembly having three injection systems - each arranged for injecting liquid cement into the pad under the pipeline, and consisting of a housing in which a a bottom portion equipped container having a flexible discharge tube and which is designed to be capable of being filled with liquid cement.

147952 2 at betjeningsaggregatets første indsprøjtnings-system omfatter et aggregat, der er anbragt på beholderens bunddel og er forbundet med beholderens fleksible afgangsrør, og som består af en rotationspumpe og en 5 hydraulikmotor, der kan drive rotationspumpen og kan betjenes af en udragende styrearm, som kan betjenes af undervandsfartøjets arbejdsarm, at der ved den fri ende af beholderens fleksible afgangsrør er anbragt en kobling, der ved hjælp af en ud-10 ragende styrearm, som kan betjenes af undervandsfartøjets arbejdsarm, kan kobles til og fra et koblingsorgan, der befinder sig ved den fri ende af et fleksibelt tilgangsrør, der indeholder en kontraventil og udgår fra den mod betjeningsaggregatet vendende side af pudens 15 bunddel, der ved sin modsatte side har et beslag, som tjener til udløselig fastgørelse af undervandsfartøjets arbejdsarm til pudens bunddel for indføring af den endnu tomme pude under rørledningen, at betjeningsaggregatets andet indsprøjtningssy-20 stem omfatter et batteri af trykluftflasker, der er båret af huset og er forbundet med beholderens topdel via en ledning, der har en trykformindsker og en afspærringsventil, der kan betjenes af en udragende styrearm, som kan betjenes af undervandsfartøjets arbejdsarm, og 25 at betjeningsaggregatets tredje indsprøjtningssy stem omfatter en slange, der forbinder en trykluftkilde ombord på depotskibet med beholderens topdel via en afspærringsventil, der kan betjenes af en udragende styrearm, som kan betjenes af undervandsfartøjets arbejdsarm.The first injection system of the actuator comprises an assembly disposed on the bottom of the container and connected to the flexible outlet pipe of the container, consisting of a rotary pump and a hydraulic motor capable of operating the rotary pump and operable by a projecting control arm which can be operated by the working arm of the submarine, that at the free end of the flexible discharge tube of the container is arranged a coupling which can be coupled to and from a coupling means which is located by a projecting control arm which can be operated by the working arm of the submarine at the free end of a flexible inlet pipe containing a non-return valve and starting from the side facing the actuator of the bottom portion of the pad 15 having at its opposite side a bracket for releasably attaching the underwater vessel's working arm to the bottom of the pad for inserting it still empty cushion below the pipeline, the second injection system of the control unit comprising again a battery of compressed air cylinders carried by the housing and connected to the top of the container via a conduit having a pressure reducer and a shut-off valve operable by a protruding control arm operable by the underwater vessel's working arm and the third injection system of the operating unit voice includes a hose connecting a source of compressed air onboard the ship to the top of the container via a shut-off valve which can be operated by a projecting control arm, which can be operated by the underwater vessel's working arm.

30 Med denne udformning opnår man en konstruktion, der opfylder de stillede krav og derved har betydelige fordele i sammenligning med hidtil kendte, til lignende formål anvendte konstruktioner, som kan operere på store havdybder under anvendelse af et undervandsfar-35 tøj.30 This design achieves a construction that meets the requirements and thereby has significant advantages over previously known, similarly used structures capable of operating at great depths of sea using an underwater craft.

3 1479523 147952

Den tilstræbte overordentligt gode driftsøkonomi sikres i væsentlig grad af den omstændighed, at betjeningsaggregatet kan genindvindes i sin helhed, når det efter operationens afslutning er udløst fra den færdige 5 under s tø tn ing, hvorved udgifterne, der er forbundet med at få tilvejebragt denne understøtning, bliver meget små.The extremely good operating economy sought is substantially ensured by the fact that the control unit can be fully recovered when it is triggered from the completed 5 under support after the end of the operation, whereby the costs associated with obtaining this support , become very small.

Apparatet har tre indsprøjtningssystemer, der hver kan anvendes til indsprøjtning af den flydende cement i 10 puden under rørledningen. Hvert af disse indsprøjtningssystemer muliggør, at der selv ved store havdybder, herunder ekstremt store havdybder på 600 meter og mere, kan ske indsprøjtning af den flydende cement i puden - via beholderens fleksible afgangsrør og pudens fleksible 25 tilgangsrør. Indsprøjtningen sker - uden problemer - på en enkel og upåklagelig måde, hvortil kommer den reservemulighed, som forefindes i kraft af, at der anvendes flere indsprøjtningssysterner.The apparatus has three injection systems, each of which can be used to inject the liquid cement into the pad under the pipeline. Each of these injection systems enables the liquid cement to be injected into the pad even at large sea depths, including extremely large sea depths of 600 meters and more - via the container's flexible discharge pipe and the pad's flexible 25 inlet pipe. The injection is done - without problems - in a simple and impeccable way, in addition to the reserve option that exists because of the use of several injection systems.

Den omstændighed, at apparatets operering på store 2q havdybder (600 meter og derover) kræver anvendelse af et undervandsfartøj, fordi dykkere ikke kan arbejde under de derved optrædende enorme tryk, bevirker, at betjeningsaggregatet må være indrettet som foreskrevet til at kunne betjenes på en hensigtsmæssig måde fra nævnte un-25 dervandsfartøj, nemlig ved hjælp af betjeningsaggregatets udragende styrearme.The fact that the operation of the apparatus at large 2q depths of sea (600 meters and above) requires the use of a submarine vessel because divers are unable to operate under the resulting tremendous pressure, means that the control unit must be arranged as prescribed to operate in an appropriate manner. way from said underwater vessel, namely by means of the projecting arm's projecting guide arms.

Til det første indsprøjtningssystem hører der en udragende styrearm, der kan betjene dette systems hydraulikmotor, og som kan betjenes af undervandsfartøjets ar-3Q bejdsarm. Til koblingen, der er anbragt ved den fri ende af beholderens fleksible afgangsrør, hører der en udragende styrearm, der kan betjene koblingen, og som også kan betjenes af undervandsfartøjets arbejdsarm. Til det andet indsprøjtningssystem hører der en udragende styre-35 arm, der kan betjene dette systems afspærringsventil, og som ligeledes kan betjenes af undervandsfartøjets ar- % 147952 4 bejdsarm. Til det tredje indsprøjtningssystem hører der sluttelig en udragende styrearm, der kan betjene dette systems afspærringsventil, og som også kan betjenes af undervandsfartøjets arbejdsarm. Endelig har 5 pudens bunddel ved sin modsat betjeningsaggregatet vendende side et beslag, som anvendes til udløselig fastgørelse af pudens bunddel til undervandsfartøjets arbejdsarm for indføring af den endnu tomme pude under rørledningen.The first injection system includes a protruding control arm that can operate this system's hydraulic motor and can be operated by the underwater vessel's Ar-3Q working arm. The coupling, which is located at the free end of the flexible outlet pipe of the container, includes a projecting control arm which can operate the coupling and which can also be operated by the working arm of the underwater vessel. The second injection system includes a protruding control arm which can operate the shut-off valve of this system and which can also be operated by the underwater vessel's working arm. Finally, the third injection system includes a protruding control arm which can operate this system's shut-off valve and which can also be operated by the underwater vessel's working arm. Finally, at the opposite side of the operating unit, the bottom of the cushion has a bracket which is used for releasably attaching the bottom of the cushion to the underwater vessel's working arm for insertion of the still empty cushion under the pipeline.
