Description

MONTASJEANORDNING OG METODE FOR MONTERING AV FLYTENDE VINDTURBINER ASSEMBLY DEVICE AND METHOD FOR ASSEMBLY OF FLOATING WIND TURBINES

Denne oppfinnelsen vedrører en anordning for å kunne montere vindturbiner uten bruk av eksterne heisekraner fundamentert i bakkenivå. Nærmere bestemt dreier det seg om en anordning der en tårnstruktur til selve vindturbinen benyttes til en bærende struktur for montasjeanordningen. This invention relates to a device for being able to mount wind turbines without the use of external cranes based at ground level. More specifically, it concerns a device where a tower structure for the wind turbine itself is used as a supporting structure for the assembly device.

Bakgrunn for oppfinnelsen Background for the invention

En moderne vindturbin består i hovedsak av en sylindrisk tårnstruktur hvor det på toppen av tårnstrukturen er montert en propell som via aksling og opplagring kobles til en generator. I tillegg til generator er det anbrakt nødvendig hjelpeutstyr som transformator og styre – og kontrollanlegg. A modern wind turbine mainly consists of a cylindrical tower structure where a propeller is mounted on top of the tower structure and is connected to a generator via shafting and storage. In addition to the generator, the necessary auxiliary equipment such as a transformer and steering - and control system has been installed.

Toppstrukturen (nacellen) er opplagret mot en sylindrisk tårnstruktur med lager, slik at nacellen kan roteres om en vertikalakse til tårnstrukturen og tilpasses varierende vindretninger. The top structure (the nacelle) is supported against a cylindrical tower structure with bearings, so that the nacelle can be rotated about a vertical axis to the tower structure and adapted to varying wind directions.

Vindturbinene har utviklet seg fra små landbaserte vindturbiner på 200-300 kW til dagens store turbiner på ca.10 MW. Hovedstrukturen på oppbyggingen er den samme, det er i all hovedsak bare foretatt en skalering av dimensjoner og arrangement. The wind turbines have developed from small land-based wind turbines of 200-300 kW to today's large turbines of approx. 10 MW. The main structure of the build-up is the same, there has essentially only been a scaling of dimensions and arrangement.

Nå er det under planlegging og utvikling store flytende vindturbiner opp mot 15 – 20 MW installert effekt. Large floating wind turbines with an installed power of up to 15-20 MW are now being planned and developed.

På dagens vindturbiner bygges nacellen i en samlet konstruksjon som heises opp på toppen av tårnstrukturen når denne er montert opp i full høyde. Vindturbiner på ca. 10 MW har gjerne en tårnhøyde på ca.200m og en nacellevekt på 300 – 400 tonn. Når 300 – 400 tonn skal heises ca.200 m opp kreves store og kostbare heiseinnretninger. For flytende vindturbiner er utfordringen i tillegg at det må benyttes flytende fundament for heiseinnretningen som igjen påvirkes av bølgebevegelser. Tidsintervallene for akseptable bølgeforhold blir svært korte noe som medfører at montasje av flytende vindturbiner er teknisk krevende og kostbart. On today's wind turbines, the nacelle is built in an integrated construction that is lifted up on top of the tower structure when it has been assembled to its full height. Wind turbines of approx. 10 MW usually has a tower height of approx. 200m and a nacelle weight of 300 - 400 tonnes. When 300 - 400 tonnes are to be lifted approx. 200 m up, large and expensive lifting devices are required. For floating wind turbines, the additional challenge is that a floating foundation must be used for the lifting device, which in turn is affected by wave movements. The time intervals for acceptable wave conditions are very short, which means that the installation of floating wind turbines is technically demanding and expensive.

Patentdokumentet US2018282134 beskriver en kran for montering av en flerhet søyleelementer for en flytende vindturbin omfattende en nacelle og propellblader. Kranen festes til én side av et søyleelementene, i det hver av søyleelementene omfatter et utvendig feste for kranen. Kranen forflyttes trinnvis oppover ved hjelp av hydrauliske sylindre. Én ulempe med denne løsningen, er at søyleelementene påføres et bøyemoment i det kranen kun er montert på én side. Alternativt kan det brukes to kraner, én på hver side av søyleelementene. En ulempe med dette, er at det kreves en synkron betjening av de to kranene, noe som kompliserer monteringen. I tillegg må hvert av søyleelementene ha dobbelt sett med fester for kranen. The patent document US2018282134 describes a crane for mounting a plurality of column elements for a floating wind turbine comprising a nacelle and propeller blades. The crane is attached to one side of one of the column elements, in that each of the column elements comprises an external attachment for the crane. The crane is moved upwards in steps using hydraulic cylinders. One disadvantage of this solution is that the column elements are subjected to a bending moment when the crane is only mounted on one side. Alternatively, two cranes can be used, one on each side of the column elements. A disadvantage of this is that synchronous operation of the two cranes is required, which complicates the installation. In addition, each of the column elements must have a double set of fasteners for the crane.

Oppfinnelsen har til formål å avhjelpe eller å redusere i det minste én av ulempene ved kjent teknikk, eller i det minste å skaffe til veie et nyttig alternativ til kjent teknikk. The purpose of the invention is to remedy or to reduce at least one of the disadvantages of known technology, or at least to provide a useful alternative to known technology.

Formålet oppnås ved trekkene som er angitt i nedenstående beskrivelse og i de etterfølgende patentkravene. The purpose is achieved by the features indicated in the description below and in the subsequent patent claims.

Generell beskrivelse av oppfinnelsen General description of the invention

Det er tilveiebrakt en montasjeanordning som gjør det mulig å montere en vindturbin med en sylindrisk stålstruktur, en nacelle og en propell ved hjelp av en montasjeanordning som klatrer og benytter selve tårnstrukturen som del av en bærende struktur. Med tårnstruktur kan det heri forstås en søyle. A mounting device is provided which makes it possible to mount a wind turbine with a cylindrical steel structure, a nacelle and a propeller by means of a mounting device which climbs and uses the tower structure itself as part of a supporting structure. A tower structure can here be understood as a pillar.

For å oppnå dette benyttes to sylindriske langstrakte jekkeelement som vekselvis festes til tårnstrukturen. Tårnstrukturen settes sammen av langstrakte søyleelementer som stables oppå hverandre i passende lengder. To achieve this, two cylindrical elongated jack elements are used which are alternately attached to the tower structure. The tower structure is assembled from elongated column elements that are stacked on top of each other in suitable lengths.

Jekkeelementene festes til flensforbindelser mellom hvert sylindrisk søyleelement og forskyves en seksjon oppover. På toppen av det ene jekkeelementet er det anbrakt en kranbom med hydrauliske sylindere slik at kranbommen kan hente opp søyleelementer og plassere disse sentrisk over tidligere oppsatte søyleelementer. Forskyvning av jekkeelementene utføres med wire og vinsjer som står på en arbeidsplattform festet til det nederste søyleelementet. The jack elements are attached to flange connections between each cylindrical column element and are offset one section upwards. A crane boom with hydraulic cylinders is placed on top of one jacking element so that the crane boom can pick up column elements and place them centrally over previously installed column elements. Displacement of the jacking elements is carried out with wire and winches that stand on a work platform attached to the bottom column element.

Montering av nacellen utføres ved at selve nacellen er delt opp i flere moduler slik at vekten av hver modul er akseptabel i forhold til kranbommen på jekkeelementet. For mindre vindturbiner monteres nacellen i én modul. Kranbommen på toppen av jekkeelementet svinger inn nacellemodulene i posisjon. Oppheising skjer med wire og vinsjer. Selve propellbladene heises også opp med kranbommen og wire og festes til navet. Assembly of the nacelle is carried out by dividing the nacelle into several modules so that the weight of each module is acceptable in relation to the crane boom on the jacking element. For smaller wind turbines, the nacelle is mounted in one module. The crane boom on top of the jack element swings the nacelle modules into position. Hoisting is done with wire and winches. The propeller blades themselves are also hoisted up with the crane boom and wire and attached to the hub.

Når monteringen av vindturbinen er fullført heises jekkeelementene ned og demonteres. When the assembly of the wind turbine is completed, the jacking elements are lifted down and dismantled.

Oppfinnelsen skal nå forklares nærmere med henvisning til figurer som anskueliggjør et foretrukket utførelseseksempel. The invention will now be explained in more detail with reference to figures which illustrate a preferred embodiment.

På figurene angir henvisningstallet 1 en vertikal sylindrisk søyle satt sammen av sylindriske søyleelement 11. Søylen 1 er montert vertikalt til et flytefundament 5 med forankringer 10. Over en havoverflate 4 er det anordnet en arbeidsplattform 9 til bruk ved installasjon. På toppen av søylen 1 er det montert en nacelle 3 som inneholder tekniske installasjoner som generator og kontrollanlegg. En propell 200 roterer når vinden blåser, og gir kraft til strømproduksjon. In the figures, the reference number 1 denotes a vertical cylindrical column composed of cylindrical column elements 11. The column 1 is mounted vertically to a floating foundation 5 with anchorages 10. Above a sea surface 4, a working platform 9 is arranged for use during installation. A nacelle 3 is mounted on top of the pillar 1, which contains technical installations such as a generator and control system. A propeller 200 rotates when the wind blows, providing power for power generation.

Når vindturbinen skal monteres er flytefundamentet 5 forankret og posisjonert på planlagt sted. Deretter ankommer et fartøy 7 med alle komponentene som skal til for å montere vindturbinen. En kran 8 benyttes til å håndtere de enkelte vindturbinelementene fra fartøyet 7 til riktig monteringsposisjon. When the wind turbine is to be installed, the floating foundation 5 is anchored and positioned in the planned location. A vessel 7 then arrives with all the components needed to mount the wind turbine. A crane 8 is used to handle the individual wind turbine elements from the vessel 7 to the correct mounting position.

Første trinn i monteringen er montering av et første vertikalt søyleelement 11 til flytefundamentet 5. Monteringen utføres med kranen 8. Når denne monteringen er utført monteres et første jekkeelement 12 og et andre jekkeelement 13 bestående av halvsirkelelementer og skrudd sammen med flensforbindelser 16 og 17. The first step in the assembly is the assembly of a first vertical column element 11 to the floating foundation 5. The assembly is carried out with the crane 8. When this assembly has been carried out, a first jack element 12 and a second jack element 13 consisting of semi-circular elements and screwed together with flange connections 16 and 17 are mounted.

Det første jekkeelement 12 er forsynt med en kranbom 14 opplagret i bolteforbindelsen 20 og betjent av hydrauliske sylindere 15. Kranbommen 14 er videre forsynt med wireruller 18 for en wire 21 som er forbundet til en vinsj 22 plassert på en arbeidsplattform 9. The first jacking element 12 is provided with a crane boom 14 stored in the bolt connection 20 and operated by hydraulic cylinders 15. The crane boom 14 is also provided with wire rollers 18 for a wire 21 which is connected to a winch 22 placed on a work platform 9.

Jekkeelementene 12 og 13 festes til flensforbindelser 24 mellom søyleelementene 11 med klakker 25 som går i inngrep 27 mot flensen 24. The jack elements 12 and 13 are attached to flange connections 24 between the column elements 11 with lugs 25 that engage 27 against the flange 24.

Ett søyleelement 11 heises nå på plass vertikalt ved hjelp av kranbommen 14 og wiren 21 koblet til vinsjen 22 plassert på arbeidsplattformen 9. One column element 11 is now lifted into place vertically by means of the crane boom 14 and the wire 21 connected to the winch 22 placed on the work platform 9.

Søyleelementet 11 forbindes til nedenfor søyleelement 11 med flens 24 og skrueforbindelse. Column element 11 is connected to below column element 11 with flange 24 and screw connection.

Klakkeforbindelsen 27 på det første jekkeelement 12 frigjøres og det første jekkeelementet 12 heises opp ved hjelp av en første vinsj 50 og en første wire 30 over wireruller 55 festet til det andre jekkeelementet 13 videre til feste 31 på det første jekkeelementet 12. The lug connection 27 on the first jacking element 12 is released and the first jacking element 12 is raised by means of a first winch 50 and a first wire 30 over wire rollers 55 attached to the second jacking element 13 further to attachment 31 on the first jacking element 12.

Det første jekkeelement 12 festes nå til toppen av oppheist søyleelement 11 med klakker 25 i inngrep mot flensen 24. The first jack element 12 is now attached to the top of the raised column element 11 with lugs 25 in engagement with the flange 24.

Det andre jekkeelement 13 heises deretter opp ved hjelp av en andre vinsj 35 og en andre wire 30 over wireruller 41 og festet til det første jekkeelement 12 i punkt 36. Det andre jekkeelementet 13 festes nå til flensforbindelsen 24 mellom oppheist og nedenfor søyleelementer 11 med klakker 25. The second jacking element 13 is then hoisted up using a second winch 35 and a second wire 30 over wire rollers 41 and attached to the first jacking element 12 at point 36. The second jacking element 13 is now attached to the flange connection 24 between the hoisted and below column elements 11 with lugs 25.

Det første jekkeelement 12 med kranbommen 14 er nå stabilt festet til søylen 1 og i posisjon for oppheising av neste søyleelement 11. Prosessen gjentas til et ønsket antall søyleelementer 11 er plassert. The first jack element 12 with the crane boom 14 is now stably attached to the column 1 and in position for lifting the next column element 11. The process is repeated until a desired number of column elements 11 have been placed.

Etter at ønsket antall søyleelementer 11 er plassert heises nacelleelementer 45, 46 og 47 på plass ved hjelp av wiren 21 og vinsjen 22. After the desired number of column elements 11 have been placed, the nacelle elements 45, 46 and 47 are lifted into place using the wire 21 and the winch 22.

Navet 48 for propellbladene 2 heises også på plass ved hjelp av kranbommen 14 og wire 21, deretter heises propellbladene 2 på plass ved bruk av heiseverktøyet 49. The hub 48 for the propeller blades 2 is also lifted into place using the crane boom 14 and wire 21, then the propeller blades 2 are lifted into place using the lifting tool 49.

Når montasjen er fullført heises jekkeelementene 12 og 13 ned og demonteres. When assembly is complete, the jack elements 12 and 13 are lifted down and dismantled.
