FRAMGANGSMÅTE FOR FORANKRING AV FLYTENDE VINDTURBIN SAMT SYSTEM FOR ANVENDELSE VED UTØVELSE AV FRAMGANGSMÅTEN PROCEDURE FOR ANCHORING A FLOATING WIND TURBINE AND SYSTEM FOR USE IN EXERCISE OF THE PROCEDURE
Det beskrives en framgangsmåte for forankring av flytende vindturbin, nærmere be-stemt hvor framgangsmåten omfatter trinnene: en koplingsenhet som er forsynt med flere strekkfortøyninger fastgjort i en sjø-bunn, anordnes neddykket i en vannmasse i en foreskrevet første dybde under en vannoverflate; A procedure for anchoring a floating wind turbine is described, more precisely where the procedure includes the steps: a coupling unit which is equipped with several tension moorings fixed in a seabed, is arranged submerged in a body of water at a prescribed first depth below a water surface;
en flytende vindturbinenhet som er forsynt med et oppdriftslegeme med dyptgående lik en andre dybde, hvor den første dybden er større enn den andre dybden, forskyves inn over koplingsenheten; a floating wind turbine assembly provided with a buoyancy body having a draft equal to a second depth, the first depth being greater than the second depth, is displaced over the coupling assembly;
vindturbinenheten ballasteres og forskyves vertikalt til den første dybden er lik den andre dybden og vindturbinenheten understøttes av koplingsenheten. the wind turbine unit is ballasted and shifted vertically until the first depth is equal to the second depth and the wind turbine unit is supported by the coupling unit.
Det beskrives også et forankringssystem for anvendelse ved utøvelse av framgangsmåten. An anchoring system is also described for use when carrying out the procedure.
En vindturbin som plasseres til havs, anbringes på et fundament anordnet på havbunnen, eller, i det minste for vindturbiner med horisontal rotasjonsakse, med et tårn som er anordnet flytende i vannmassene, for eksempel ved at det er delvis nedsenket i vannmassene og rager med et endeparti opp over vannmassene, eller at vindturbinen er en integrert, oppragende del av en flytende innretning, for eksempel en flytende plattform eller lignende. Den flytende vindturbinen forankres, direkte eller indirek-te, i havbunnen. A wind turbine placed offshore is placed on a foundation arranged on the seabed, or, at least for wind turbines with a horizontal axis of rotation, with a tower arranged floating in the water masses, for example by being partially submerged in the water masses and projecting with a end part above the bodies of water, or that the wind turbine is an integrated, upstanding part of a floating device, for example a floating platform or the like. The floating wind turbine is anchored, directly or indirectly, to the seabed.
Det er kjent en lang rekke måter å forankre flytende vindturbiner. Forankringen sørger både for at vindturbinen opprettholder sin posisjon, dvs. forhindres i å drive av, og den sørger som regel for at stabiliteten øker, dvs. at hiv- og krengningsbevegelsene dempes. Å forankre en flytende installasjon er tidkrevende, kostbart og komplisert, og i havområder hvor vindturbiner monteres, er det naturligvis ofte mye vind og bølger, noe som fører til at installeringsoperasjoner som tar lang tid, ofte blir vanskelig å gjennomføre pga. mangel på tilstrekkelig lange perioder med brukbare arbeidsforhold. US 7476074 B2 beskriver et flytende fundament nedsenket under en vannflate og forankret til havbunnen med kabler eller kjettinger. Pa fundamentet, som befinner seg under bølgebevegelsesområdet, er det reist en struktur, særlig et vindturbintårn. A wide variety of ways to anchor floating wind turbines are known. The anchoring both ensures that the wind turbine maintains its position, i.e. is prevented from drifting off, and it usually ensures that stability increases, i.e. that the heave and roll movements are dampened. Anchoring a floating installation is time-consuming, expensive and complicated, and in sea areas where wind turbines are installed, there is naturally often a lot of wind and waves, which means that installation operations that take a long time are often difficult to carry out due to lack of sufficiently long periods of workable working conditions. US 7476074 B2 describes a floating foundation submerged below a water surface and anchored to the seabed with cables or chains. On the foundation, which is located below the wave movement area, a structure, in particular a wind turbine tower, has been erected.
US 7293960 B2 beskriver en flytende kraftgeneratorsammenstilling som omfatter minst tre flytende enheter oppankret i bunnen under vannmassen. US 7293960 B2 describes a floating power generator assembly comprising at least three floating units anchored at the bottom under the body of water.
US 2009/0072544 Al beskriver en vindturbin med vertikal akse montert på en plattform. Plattformen kan være sammensatt av sammenkoplede modulelementer. Plattformen er halvt nedsenket med turbintårnet ragende opp over en vannflate og med en motvekt som strekker seg nedover fra plattformen. Alternativt kan plattformen flyte på vannflaten og ha flere armer som strekker seg utover fra plattformen for å øke plattformens utstrekning. For oppankring av turbinen kan det anvendes ankersystem som forbindes med havbunnen og tillater at vindturbinen justeres aktivt eller passivt for å tilpasses endringer i vannivå grunnet tidevann eller dønninger. US 2009/0072544 Al describes a vertical axis wind turbine mounted on a platform. The platform can be composed of interconnected modular elements. The platform is semi-submerged with the turbine tower rising above a water surface and with a counterweight extending downward from the platform. Alternatively, the platform may float on the surface of the water and have several arms extending outward from the platform to increase the reach of the platform. For anchoring the turbine, an anchor system can be used which is connected to the seabed and allows the wind turbine to be adjusted actively or passively to adapt to changes in water level due to tides or swells.
EP 1666722 Al beskriver et festesystem for flytende vindturbiner, hvor det til foten av en bærestamme er anordnet en neddykket struktur innrettet til å kunne tilveiebringe oppdrift til vindturbinen, idet nevnte neddykkede struktur er utformet til å fungere som ledeelement for en kabel som forbinder foten med i det minste et sentralt ankerelement. Flere bøyer er arrangert i nærheten av vindturbinen, og hver bøye er forbundet med uavhengige ankerelement via kjettinger og til foten ved hjelp av kabler, og bøyene er anordnet omkring bærestammen i en viss avstand derfra. EP 1666722 Al describes a fastening system for floating wind turbines, where a submerged structure is arranged at the foot of a support stem designed to be able to provide buoyancy to the wind turbine, said submerged structure being designed to function as a guide element for a cable that connects the foot with at least a central anchor element. Several buoys are arranged near the wind turbine, and each buoy is connected to independent anchor elements via chains and to the footing using cables, and the buoys are arranged around the support stem at a certain distance from there.
GB 2454585 A beskriver en framgangsmåte for transport av en bygningsstruktur, for eksempel en vindturbin, i en vannmasse. I det minste én flåte er tilknyttet strukturen på en slik måte at strukturen flyter stabilt i vannet idet flåten omkranser strukturen, og et bunnparti av strukturen strekker seg nedover fra flåtens underkant. Flåten kan være tildannet av to lektere som er forbundet med hverandre for å holde fast i strukturen. GB 2454585 A describes a method for transporting a building structure, for example a wind turbine, in a body of water. At least one raft is connected to the structure in such a way that the structure floats stably in the water as the raft encircles the structure, and a bottom part of the structure extends downwards from the lower edge of the raft. The raft can be made of two barges which are connected to each other to hold the structure.
Oppfinnelsen har til formål å avhjelpe eller å redusere i det minste en av ulempene ved kjent teknikk. The purpose of the invention is to remedy or to reduce at least one of the disadvantages of known technology.
Formålet oppnås ved trekk som er angitt i nedenstående beskrivelse og i etterfølgende patentkrav. The purpose is achieved by features that are stated in the description below and in subsequent patent claims.

Vindturbinenheten er forsynt med oppdriftslegemer og kan forflyttes i vannmassen med et dyptgående som er mindre enn koplingsenhetens avstand fra vannoverflaten. Vindturbinenheten kan ved ballastering senkes til støttende anlegg mot en kontaktflate på koplingsenheten. Vindturbinenheten og koplingsenheten låses fortrinnsvis til hverandre ved hjelp av koplingselementer som går I løsgjørbart inngrep med hverandre. Den sammenkoplede enhetens oppdrift avstemmes for å gi et strekk i fortøyningene under alle operasjonelle forhold og for å gi ønsket stabilitet på enheten. The invention provides a foundation for a floating wind turbine unit, the foundation being provided as a coupling unit anchored to a seabed by means of several tension moorings and arranged submerged in a body of water at a prescribed depth below a water surface. The wind turbine unit is equipped with buoyancy bodies and can be moved in the body of water with a draft that is less than the coupling unit's distance from the water surface. By means of ballasting, the wind turbine unit can be lowered to a supporting structure against a contact surface on the coupling unit. The wind turbine unit and the coupling unit are preferably locked to each other by means of coupling elements which releasably engage with each other. The coupled unit's buoyancy is tuned to provide a stretch in the moorings under all operational conditions and to provide the desired stability of the unit.
Ved at sammenkoplingen mellom vindturbinenheten og koplingsenheten kan reverse-res, kan vindturbinen bringes til en havn eller annet farvann for vedlikehold. As the connection between the wind turbine unit and the coupling unit can be reversed, the wind turbine can be brought to a harbor or other body of water for maintenance.

The wind turbine unit 3 is moved floating in the body of water 1, for example with the help of one or more tugboats (not shown), until the wind turbine unit 3 is positioned directly above the coupling unit 21. During ballasting, the wind turbine unit 3 is then lowered to a supporting structure against the coupling unit 21. The wind turbine unit 3 is attached to the coupling unit 21 using the coupling elements 212, 312. The buoyancy of the wind turbine unit 3 and the coupling unit 21 is then adjusted using the ballasting devices 213, 313 to achieve the desired tension in the tension moorings 22 and the desired weight distribution and stability.
Dersom vindturbinenheten 3 krever vedlikehold som ikke kan utføres til havs, kan den koples fra koplingsenheten 21 ved å reversere prosessen beskrevet ovenfor og slepes til en skjermet havn eller farvann, hvor vedlikeholdet lettere kan utføres. If the wind turbine unit 3 requires maintenance that cannot be carried out at sea, it can be disconnected from the coupling unit 21 by reversing the process described above and towed to a sheltered harbor or waters, where the maintenance can be carried out more easily.
Det er innlysende at selv om det her er beskrevet en vindturbinenhet 3 med horisontal rotoraksel 332, er prinsippet ifølge oppfinnelsen anvendelig også for vindturbiner av den typen som oppviser en vertikal rotasjonsakse. It is obvious that although a wind turbine unit 3 with a horizontal rotor axis 332 is described here, the principle according to the invention is also applicable to wind turbines of the type that have a vertical axis of rotation.
