Description
Foreliggende oppfinnelse angår et offshoreanlegg for oppdrett og oppbevaring av fisk og lignende sjødyr, med en halvt neddykkbar flyteplatform, en bunnramme og oppdriftssøyler som forbinder plattformen med bunnrammen, samt med ett eller flere begrensede oppholdsrom for fiskene. The present invention relates to an offshore facility for breeding and storing fish and similar marine animals, with a semi-submersible floating platform, a bottom frame and buoyancy columns that connect the platform to the bottom frame, as well as with one or more limited living spaces for the fish.
Ved oppdrett og oppbevaring av fisk anvendes forskjellige produksjonssystemer. Det er således kjent den konvensjonelle drift av dammer med stående vann eller med gjennomstrømmende vann. Bruk av dammer med stående vann krever vannbehandling. I begge tilfeller er ofte oksygentilførsel i forbindelse med ventilasjon nødvendig. I nyere produksjonssystemer benyttes fiskebassenger eller nettinginnhegninger. Også for fiskebassenger skjer en vannutskifting enten ved stadig gjennom-strømmende vann eller i forbindelse med vannbehandlingen. Dessuten skjer ventilasjon og oksygentilførsel til fiske-bassengene. For nettinginnhegninger skjer vannutskiftingen fra det omgivende vann, mens ventilasjon ikke er ubetinget nødvendig. Nettinginnhegninger er imidlertid problematiske av andre grunner, ettersom de ikke danner noen tilstrekkelig avskjerming mot mekaniske påvirkninger fra omgivelsene, og ettersom de ikke hindrer forurensning fra omgivelsene i form av oljepest, algepest eller lignende. Mekaniske påvirkninger fra omgivelsene, slik som f. eks drivende treverk, eventuelt også drivis og angripende rovfisk kan føre til så vidtrekkende skader og ødeleggelse av nettinginnhegningen at hele fiskeproduksjonen går tapt. Dette gjelder først og fremst når fiskeproduksjonen, henholdsvis oppdrettet og oppbevaringen skjer i et offshore-anlegg. I dette tilfelle er nemlig stedsbetingelsene særlig vanskelige. Dessuten er ikke nettinginnhegninger tilstrekkelig sikre mot tyveri og sabotasje. Different production systems are used in the farming and storage of fish. The conventional operation of dams with standing water or with flowing water is thus known. Using ponds with standing water requires water treatment. In both cases, oxygen supply in connection with ventilation is often necessary. In newer production systems, fish pools or net enclosures are used. For fish pools, too, a water exchange takes place either by constantly flowing water or in connection with the water treatment. In addition, ventilation and oxygen are supplied to the fishing pools. For mesh enclosures, the water exchange takes place from the surrounding water, while ventilation is not absolutely necessary. However, mesh enclosures are problematic for other reasons, as they do not provide sufficient protection against mechanical influences from the surroundings, and as they do not prevent pollution from the surroundings in the form of oil spills, algae blooms or the like. Mechanical influences from the surroundings, such as drifting wood, possibly also drift ice and attacking predatory fish can lead to such far-reaching damage and destruction of the net enclosure that the entire fish production is lost. This primarily applies when fish production, farming and storage takes place in an offshore facility. In this case, the site conditions are particularly difficult. Furthermore, mesh enclosures are not sufficiently secure against theft and sabotage.
Formålet med den foreliggende oppfinnelse er å komme frem til et offshoreanlegg av den innledningsvis angitte type og som muliggjør oppdrett og oppbevaring av fisk slik at anlegget beskyttes mot skadelige påvirkninger utenfra, i form av mekaniske påkjenninger og forurensning. The purpose of the present invention is to arrive at an offshore facility of the type indicated at the outset and which enables the farming and storage of fish so that the facility is protected against harmful influences from the outside, in the form of mechanical stresses and pollution.
I henhold til oppfinnelsen er dette oppnådd ved at det i flyteplattformen er anbragt fiskesiloer som danner oppholdsrom, idet siloene omfatter stengbare vinduer med gitter samt en innretning for å fjerne forurensninger. Når det gjelder forurensninger kan det dreie seg om utskillinger fra fiskene, foringsrester eller andre forurensninger. Innen rammen av oppfinnelsen danner de neddykkede fiskesiloene og deres gittervinduer en fullverdig mekanisk beskyttelse mot skadelige påvirkninger ved mekaniske påkjenninger, slik som fra drivende treverk, eventuelt drivis eller angripende rovfisker, tyveri og sabotasje. Vindusgitrene oppviser både tilstrekkelig stabilitet og den nødvendige finmaskethet. Dessuten oppnås det også pålitelig beskyttelse mot slike forurensninger som oljepest, algepest eller lignende, ettersom gittervinduene i slike tilfeller kan stenges. Mens de åpne gittervinduene gir en stadig vanngjennomstrømning, kan når gittervinduene er stengt tilførselen av friskt vann skje fra større vanndybde, og det kan eventuelt utføres ventilasjon eller tilførsel av oksygen. En annen mulighet består i å flytte offshoreanlegget til et annet sjøområde som er uberørt av forurensning, og å forankre anlegget der. En innretning sørger for den rettidige bortførsel av forurensninger, slik at det ikke skjer noen selvforgiftning, f. eks ved ammoniakk-dannelse. Med et offshoreanlegg i henhold til oppfinnelsen kan fiskeproduksjonen intensiveres ved hjelp av naturlige stedsbetingelser, uten at en avbrytelse av vannforsyningen og forringelse av vannkvaliteten kan føre til produksjonsminskning. Resultatet er at det oppnås et meget naturlig og sikkert fiskeoppdrett, idet offshoreanlegget i henhold til oppfinnelsen utmerker seg ved kombinerte sikker-hetstiltak mot skadelige påvirkninger fra omgivelsene i form av forurensning og indre og ytre mekaniske påkjenninger. According to the invention, this has been achieved by placing fish silos in the floating platform which form living spaces, the silos comprising closable windows with gratings as well as a device for removing contaminants. When it comes to pollution, it can be secretions from the fish, lining residues or other pollution. Within the framework of the invention, the submerged fish silos and their lattice windows form a full-fledged mechanical protection against harmful effects by mechanical stress, such as from drifting wood, possibly drift ice or attacking predatory fish, theft and sabotage. The window grilles exhibit both sufficient stability and the required fineness. In addition, reliable protection is also achieved against such contamination as oil plague, algae plague or the like, as the lattice windows can be closed in such cases. While the open grid windows provide a constant flow of water, when the grid windows are closed, the supply of fresh water can take place from a greater water depth, and ventilation or the supply of oxygen can possibly be carried out. Another possibility consists in moving the offshore facility to another sea area that is untouched by pollution, and anchoring the facility there. A device ensures the timely removal of pollutants, so that no self-poisoning occurs, e.g. through ammonia formation. With an offshore plant according to the invention, fish production can be intensified with the help of natural site conditions, without an interruption of the water supply and deterioration of the water quality leading to a reduction in production. The result is that a very natural and safe fish farming is achieved, as the offshore facility according to the invention is distinguished by combined safety measures against harmful influences from the environment in the form of pollution and internal and external mechanical stresses.
I det følgende skal nevnes andre vesentlige trekk i henhold til oppfinnelsen. Flyteplattformen og bunnrammen kan ha rammedannende anbringelsesåpninger for fiskesiloene. Dermed oppnås en stillingsstabil montering av siloene. Siloene kan anbringes i åpningene ved hjelp av løfteutstyr. For å forenkle montering og demontering av siloene kan siloene styres vertikalt og sperres i bestemte høydestillinger, ved hjelp av vertikalføringer som er fordelt rundt omkretsen av siloene og rundt omkretsen av åpningene i plattformen og bunnrammen. Ved hjelp av høydereguleringen til siloene kan neddykningsdybden til disse varieres, og dette kan også utføres ved å fylle eller å tømme oppdriftsøylene, som er utstyrt med lensepumper. Dessuten kan flere siloer monteres i en åpning i plattformen og bunnrammen som er inndelt ved hjelp av tverrsteg. Siloene kan bestå av flere ved siden av og/eller over hverandre anordnede siloelementer som er montert som byggeklosser, og hvert siloelement oppviser et eller flere stengbare gittervinduer. Dette byggeklossystem muliggjør bruken av siloer med forskjellige dimensjoner, og som dessuten kan ha rundt eller mangekantet tverrsnitt. Siloene består fortrinnsvis av korrosjonsbestandig stål, stålbetong eller plast, f. eks glassfiberforsterket plast. Plasten kan være lysdiffus, gjennomsiktig eller ugjennomsiktig, i avhengighet av de fiskearter som skal oppdrettes. Som glassfiberforsterket plast kan fortrinnsvis anvendes polyester-, epoksy- eller polyvinylesterharpiks. Som termoplast kan hovedsakelig benyttes polyetylen, polypropylen og polyvinylidenfluorid. Slike silomaterialer er lysstabilere enn innhegningsmaterialer av netting eller folier. Den større materialtykkelsen til siloene forsterker denne virkning pga dybdeabsorbsjon av solstrålene. Den geometriske bestemt konstruktive fasthet kombinert med en fremragende motstands-evne mot erosjon og korrosjon for silokonstruksjonen muliggjør at vedlikeholdsomkostningene og avskrivningstiden kan beregnes. I henhold til oppfinnelsen kan siloene ha en traktformet bunn, og nederst i bunnen kan det være anordnet en pumpe med en stengbar utløpsledning, som en innretning for å fjerne stoffer som utskilles av fiskene, foringsrester og andre forurensninger. Dessuten er siloene hensiktsmessig utstyrt med friskvannsledninger og ledninger for ventilasjon og tilførsel av oksygen, ved at slike ledninger rager inn i siloene og f. eks i katastrofetilfeller blir nødvendige når gittervinduene pga forurensning fra omgivelsene må stenges slik at den gjennomgående vannstrøm avbrytes. Til friskvannsledningene og ledningene for tilførsel av oksygen og for ventilasjon er det naturligvis tilkoblet tilhørende pumper. In the following, other significant features according to the invention shall be mentioned. The floating platform and the bottom frame can have frame-forming placement openings for the fish silos. A stable installation of the silos is thus achieved. The silos can be placed in the openings using lifting equipment. To simplify assembly and disassembly of the silos, the silos can be controlled vertically and locked in certain height positions, using vertical guides that are distributed around the perimeter of the silos and around the perimeter of the openings in the platform and bottom frame. By means of the height regulation of the silos, the immersion depth of these can be varied, and this can also be done by filling or emptying the buoyancy columns, which are equipped with bilge pumps. In addition, several silos can be mounted in an opening in the platform and the bottom frame which is divided by means of cross steps. The silos can consist of several silo elements arranged next to and/or above each other which are assembled as building blocks, and each silo element has one or more closable lattice windows. This building block system enables the use of silos with different dimensions, which can also have a round or polygonal cross-section. The silos preferably consist of corrosion-resistant steel, reinforced concrete or plastic, e.g. glass fiber reinforced plastic. The plastic can be light-diffusing, transparent or opaque, depending on the fish species to be reared. Polyester, epoxy or polyvinyl ester resin can preferably be used as glass fibre-reinforced plastic. Polyethylene, polypropylene and polyvinylidene fluoride can mainly be used as thermoplastics. Such silo materials are more stable to light than fencing materials made of netting or foils. The greater material thickness of the silos reinforces this effect due to deep absorption of the sun's rays. The geometrically determined constructive firmness combined with an outstanding resistance to erosion and corrosion for the silo construction enables the maintenance costs and the depreciation period to be calculated. According to the invention, the silos can have a funnel-shaped bottom, and at the bottom of the bottom there can be a pump with a closable outlet line, as a device for removing substances secreted by the fish, lining residues and other contaminants. In addition, the silos are suitably equipped with fresh water lines and lines for ventilation and the supply of oxygen, in that such lines project into the silos and, for example, become necessary in the event of a disaster when the grid windows must be closed due to pollution from the surroundings so that the continuous flow of water is interrupted. The fresh water lines and the lines for the supply of oxygen and for ventilation are of course connected to corresponding pumps.
I henhold til en utførelsesform av oppfinnelsen kan gittervinduene stenges ved hjelp av manuelt drevne eller motordrevne skyvere eller dører. Vindusgitrene består av høyfast plast eller korrosjonbestandig stål, og er i stand til å motstå alle mekaniske påkjenninger som kan forventes. According to an embodiment of the invention, the lattice windows can be closed by means of manually operated or motor-operated sliders or doors. The window grilles consist of high-strength plastic or corrosion-resistant steel, and are able to withstand all mechanical stresses that can be expected.

Figurene viser et offshoreanlegg for oppdrett og oppbevaring av fisker eller lignende sjødyr, og i sin grunnleggende utførelse omfatter anlegget en halvt nedsenkbar flyteplattform 1, en bunnramme 2 og oppdriftssøyler 3 som forbinder plattformen 1 med bunnrammen 2 og er utstyrt med ikke viste lensepumper samt med et eller flere begrensede oppholdsrom for fiskene. I plattformen 1 er fiskesiloene 4 montert. Siloene 4 omfatter stengbare vinduer 5 med gitter 6 av tilstrekkelig stabilitet og finmaskethet, samt en innretning 7,8 for å fjerne forurensninger. Plattformen 1 og bunnrammen 2 har rammedannende monteringsåpninger 9, i hvilke siloene 4 kan anbringes ved hjelp av løfteutstyr. Siloene 4 styres for bevegelser i høyderetningen, ved hjelp av vertikalføringer 10 som er fordelt rundt omkretsen av siloene og rundt omkretsen av monteringsåpningene 9 i plattformen og bunnrammen 2, og siloene kan sperres i bestemte høydestillinger. Det er bare vist en av de nødvendige sperreinnretninger 11 for stillingssikring. Det er også mulig å montere flere siloer 4 i en monteringsåpning i plattformen 1 og i bunnrammen 2 som er inndelt ved hjelp av tverrsteg 12. Dessuten kan siloene 4 være satt sammen av flere langs og/eller over hverandre anordnede siloelementer 13, som byggeklosser, f. eks ved hjelp av ytre flenser 14 på nabo-elementer 13, og klemskinner 15 som griper utenfor flensene. The figures show an offshore facility for breeding and storing fish or similar marine animals, and in its basic design the facility comprises a semi-submersible floating platform 1, a bottom frame 2 and buoyancy columns 3 which connect the platform 1 to the bottom frame 2 and are equipped with bilge pumps, not shown, as well as with a or several limited living spaces for the fish. In the platform 1, the fish silos 4 are mounted. The silos 4 comprise closable windows 5 with grids 6 of sufficient stability and fineness, as well as a device 7,8 for removing contaminants. The platform 1 and the bottom frame 2 have frame-forming mounting openings 9, in which the silos 4 can be placed using lifting equipment. The silos 4 are controlled for movement in the height direction, by means of vertical guides 10 which are distributed around the perimeter of the silos and around the perimeter of the mounting openings 9 in the platform and bottom frame 2, and the silos can be locked in certain height positions. Only one of the necessary locking devices 11 for securing position is shown. It is also possible to mount several silos 4 in a mounting opening in the platform 1 and in the bottom frame 2 which is divided by means of transverse steps 12. Furthermore, the silos 4 can be assembled from several silo elements 13 arranged along and/or above each other, like building blocks, e.g. by means of outer flanges 14 on neighboring elements 13, and clamping rails 15 which grip outside the flanges.
Hvert siloelement 13 har et eller flere stengbare gittervinduer 5, slik at det kan oppnås en gjennomgående vannstrøm. Siloene 4 kan ha rundt eller mangekantet tverrsnitt, og består fortrinnsvis av glassfiberforsterket plast. Dessuten har hver av siloene 4 en traktlignende bunn 16, idet en pumpe 7 med en stengbar utløpsledning 8 er anordnet nederst i bunnen, som en innretning for å fjerne forurensninger. Inn i siloene 4 kan det være ført friskvannsledninger 17 og eventuelt oksygenledninger, henholdsvis ventilasjonsledninger, slik at det muliggjøres friskvannstilførsel og oksygentilførsel. Gittervinduene 5 kan stenges ved hjelp av motordrevne skyvere 18 eller dører. Vindusgitrene 6 består av høyfast plast eller korrosjonsbestandig stål. Bunnrammen 2 er for å oppnå vektbesparelse utformet som en kassekonstruksjon av stålbetong, med skumplast-fylling 19, f. eks en polystyrolfylling. Each silo element 13 has one or more closable grid windows 5, so that a continuous flow of water can be achieved. The silos 4 can have a round or polygonal cross-section, and preferably consist of glass fiber reinforced plastic. Moreover, each of the silos 4 has a funnel-like bottom 16, a pump 7 with a closable outlet line 8 being arranged at the bottom of the bottom, as a device for removing contaminants. Into the silos 4, fresh water lines 17 and possibly oxygen lines, respectively ventilation lines, can be led, so that fresh water supply and oxygen supply are made possible. The grid windows 5 can be closed using motor-driven sliders 18 or doors. The window grills 6 consist of high-strength plastic or corrosion-resistant steel. To achieve weight savings, the bottom frame 2 is designed as a box construction of reinforced concrete, with foam plastic filling 19, e.g. a polystyrene filling.
Gittervinduene 5 kan være anordnet i forskjellige høyder i siloene og med ønsket fordeling. Gittervinduene 5 kan være anordnet i bestemte høydeavstander og med en bestemt fordeling langs omkretsen av siloene 4, og de kan sikres ved hjelp av rundtgående gitter 6. For f. eks sylindriske siloer 4 er gittervinduene 5 fordelt sirkelformet i bestemte høydeavstander langs omkretsen av siloene og er sikret ved hjelp av sylinderformede gitter 6. Derved sikres optimal vanngjennomstrømning og optimal vanngjennomstrømningshastighet i siloene 4. The grid windows 5 can be arranged at different heights in the silos and with the desired distribution. The grid windows 5 can be arranged at specific height distances and with a specific distribution along the perimeter of the silos 4, and they can be secured by means of circular grids 6. For example cylindrical silos 4, the grid windows 5 are distributed circularly at specific height distances along the perimeter of the silos and is secured by means of cylindrical grids 6. This ensures optimum water flow and optimum water flow speed in the silos 4.
