Description

Foreliggende oppfinnelse angår et flytende skrog for opplagring av fortrinnsvis en eller flere vindturbiner. Skroget er av typen "semisubmersible" flyter det vil si en halvt nedsenkbar flyter. The present invention relates to a floating hull for storing preferably one or more wind turbines. The hull is of the "semisubmersible" float type, that is to say a semi-submersible float.

Med henvisning til figur 1 er det vist en kjent flyter som er betegnet som HiPRWind. Dette er en 3-søylet stålsemi med avstivninger hvor de tre søyler er avstivet i topp og bunn. With reference to Figure 1, a known float is shown which is designated as HiPRWind. This is a 3-column steel semi with braces where the three columns are braced at the top and bottom.

Et mål med foreliggende oppfinnelse er å tilveiebringe en semisubmersible flyter med en stiv bunnpongtongkonstruksjon med bøtteceller uten kompliserende avstivninger i toppen. An aim of the present invention is to provide a semi-submersible float with a rigid bottom pontoon construction with bucket cells without complicating bracing at the top.

Et annet mål er at det flytende skroget skal være robust med hensyn til turbinstørrelser. Another goal is that the floating hull should be robust with regard to turbine sizes.

Et videre mål er at et tårn, som opplagrer vindturbinen, i senter av skroget kan justeres oppover slik at utmatting i bunn av turbintårnet i stål reduseres. A further aim is that a tower, which stores the wind turbine, in the center of the hull can be adjusted upwards so that fatigue at the bottom of the steel turbine tower is reduced.

Et ytterligere mål er at det flytende skroget skal ha stor stivhet, robusthet, lang levetid og ingen behov for inspeksjon eller vedlikehold undervann. A further goal is that the floating hull should have great rigidity, robustness, long life and no need for underwater inspection or maintenance.

Et ytterligere mål er at hele den flytende turbinen skal kunne ferdigstilles på grunt vann ved kai, inklusiv turbin og tårn, og skal kunne flyte stabilt i alle faser under transport og installasjon. A further goal is that the entire floating turbine must be able to be completed in shallow water at the quay, including turbine and tower, and must be able to float stably in all phases during transport and installation.

Målene med foreliggende oppfinnelse oppnås ved et flytende, halvt nedsenkbart skrog for opplagring av fortrinnsvis en eller flere vindturbiner, omfattende et sentralt tårn som understøtter vindturbinen(ene), en stiv bunnpongtongkonstruksjon med minst tre armer i stjerne som utgår fra det sentrale tårnet og bøtteceller stivt forbundet til bunnpongtongkonstruksjonen i de ytre områder av hver av armene, kjennetegnet ved at de minst tre armer er anordnet med ballastsystem i noder under bøttecellene samt i node under tårnet. The objectives of the present invention are achieved by a floating, semi-submersible hull for the storage of preferably one or more wind turbines, comprising a central tower that supports the wind turbine(s), a rigid bottom pontoon structure with at least three arms in a star emanating from the central tower and rigid bucket cells connected to the bottom pontoon structure in the outer areas of each of the arms, characterized by the fact that at least three arms are arranged with a ballast system in nodes under the bucket cells and in a node under the tower.

Foretrukne utførelsesformer av det flytende skroget er videre utdypet i kravene 2 til og med 6. Preferred embodiments of the floating hull are further elaborated in claims 2 to 6 inclusive.

Videre oppnås målene med foreliggende oppfinnelse ved en fremgangsmåte for ferdigstillelse, utfløting og utplassering av et flytende, halvt nedsenkbart skrog for opplagring av fortrinnsvis en eller flere vindturbiner, idet skroget omfatter et sentralt tårn som understøtter vindturbinen, en stiv bunnpongtongkonstruksjon med minst tre armer i stjerne som utgår fra det sentrale tårnet og bøtteceller stivt forbundet til bunnpongtongkonstruksjonen i de ytre områder av hver av armene, kjennetegnet ved at de minst tre armer anordnes med et ballastsystem i noder under bøttecellene og i node under tårnet samt ballastanordninger i et område eller kamre mellom nodene under bøttecellene og noden under tårnet, skroget fløtes ut fra ferdigstillelsesstedet med ønsket dypgang idet kamrene mellom nodene under bøtteceller og noden under tårnet sørger for temporær oppdrift inntil nødvendig vanndyp oppnås, hvorved kamrene koples til sjø ved anvendelse av ballasteringsanordningene idet vann sluses inn i kamrene, på utplasseringsstedet opereres ballastsystemet og vannivået i nodene under bøttecellene og eventuelt noden under tårnet styres ved lesepumper inntil den ønskede fyllingsmengde og dypgang oppnås på installasjonsstedet. Furthermore, the aims of the present invention are achieved by a method for the completion, floating and deployment of a floating, semi-submersible hull for the storage of preferably one or more wind turbines, the hull comprising a central tower that supports the wind turbine, a rigid bottom pontoon structure with at least three arms in a star emanating from the central tower and bucket cells rigidly connected to the bottom pontoon structure in the outer areas of each of the arms, characterized by the fact that the at least three arms are arranged with a ballast system in nodes below the bucket cells and in a node below the tower as well as ballast devices in an area or chambers between the nodes under the bucket cells and the node under the tower, the hull is floated out from the completion site with the desired draft, as the chambers between the nodes under the bucket cells and the node under the tower provide temporary buoyancy until the required water depth is reached, whereby the chambers are connected to the sea using the ballasting devices while water is sluiced into the mrene, at the deployment site the ballast system and the water level in the nodes under the bucket cells are operated and possibly the node under the tower is controlled by reading pumps until the desired filling quantity and draft is achieved at the installation site.

I det følgende skal en utførelsesform av det flytende, nedsenkbare skroget ifølge oppfinnelsen forklares: figur 1 viser et eksempel på en kjent flyter med betegnelsen HiPRWind; In the following, an embodiment of the floating, submersible hull according to the invention will be explained: figure 1 shows an example of a known float with the designation HiPRWind;

figur 4 viser selve skroget fra figur 2 og 3 i en nedsenket stilling hvor vann-linjen er vist. figure 4 shows the hull itself from figures 2 and 3 in a submerged position where the water line is shown.

Med henvisning til figurene er et flytende, halvt nedsenkbart skrog 1 for opplagring av fortrinnsvis en eller flere vindmøller 20 vist. Skroget 1 omfatter et sentralt tårn 3 som understøtter vindturbinen 20. Videre består skroget av en stiv bunnpongtongkonstruksjon 6 med tre armer 8 i stjerne som utgår fra det sentrale tårnet 3. Frittstående bøtteceller 12 er stivt bundet til bunnpongtongkonstruksjonen 6 i de ytre områder av hver av armene 8. With reference to the figures, a floating, semi-submersible hull 1 for storage of preferably one or more wind turbines 20 is shown. The hull 1 comprises a central tower 3 which supports the wind turbine 20. Furthermore, the hull consists of a rigid bottom pontoon structure 6 with three arms 8 in a star which emanate from the central tower 3. Independent bucket cells 12 are rigidly connected to the bottom pontoon structure 6 in the outer areas of each of the arms 8.

Det flytende skroget 1 er i denne utførelse konstruert i helbetong. Det skal i denne forbindelse nevnes at bøttecellene 12 for eksempel kan være laget i stål og det resterende av skroget i betong. In this version, the floating hull 1 is constructed of solid concrete. In this connection, it should be mentioned that the bucket cells 12 can, for example, be made of steel and the rest of the hull in concrete.

Bunnpongtongkonstruksjonen 6 gir en stiv sammenkopling av det sentrale tårn 3 og bøttecellene 12, der bøttecellene 12 gir stabilitet til konstruksjonen. The bottom pontoon structure 6 provides a rigid connection of the central tower 3 and the bucket cells 12, where the bucket cells 12 provide stability to the structure.

Bunnpongtongkonstruksjonens tre armer 8 eller pongtongbjelkene gir oppdrift i temporære faser for eksempel nær land der flyteren er avhengig av å flyte med en liten dypgang. Pongtongbjelkene kan ballasteres og koples til sjø under operasjon ved hjelp av ballasteringsanordninger slik at pongtongbjelkene ikke på-virkes av hydrostatisk trykk i denne fasen og heller ikke trenger et spesielt ballast system. Pongtongbjelkene vil videre gi god demping og meget god bevegelses-karakteristikk. The bottom pontoon structure's three arms 8 or the pontoon beams provide buoyancy in temporary phases, for example near land where the floater is dependent on floating with a small draft. The pontoon beams can be ballasted and connected to the sea during operation using ballasting devices so that the pontoon beams are not affected by hydrostatic pressure in this phase and do not need a special ballast system either. The pontoon beams will also provide good damping and very good movement characteristics.

Bunnpongtongkonstruksjonen 6 er fortrinnsvis konstruert i betong hvilket gir en sterk og stiv konstruksjon slik at bøttecellene 12 kan være frittstående uten avstivninger i toppen. Det flytende, halvt nedsenkbare skroget 1 i følge foreliggende oppfinnelse resulterer i en meget enkel og ren flytekonstruksjon som i tillegg til god oppførsel, robuste egenskaper i forhold til styrke og utmatting, vedlikeholdsfri etc. også gir gode betingelser under bygging da skroget 1 kan ferdigstilles ved kai og flyte på bunnpongtongkonstruksjonen 6 med liten dypgang inkludert turbin mont-ert. Det flytende, halvt nedsenkbare skroget 1 krever således kun meget enkelt mekanisk utstyr da man etter tauing og under installasjon sluser inn vann i pong-tongen og kopler til sjø, og det eneste man behøver å kontrollere under operasjo-nen er vannivåer i noder under bøttecellene 12 og tårnet 3 hvilket uføres ved hjelp av lensepumper. Det skal til slutt nevnes at det flytende, halvt nedsenkbare skroget 1 kan bygges i forskjellige materialer, for eksempel i helbetong eller som en "hybrid". En hybrid løsning med bøtteceller 12 i stål, det vil si fra nivå topp bunnpongtongkonstruksjon 6, gir en lettere konstruksjon og dermed redusere minste dypgang under slep samt i operasjon i forhold til en utførelse i helbetong. Valg av materiale vil være avhengig av hvor det flytende, halvt nedsenkbare skroget 1 bygges og hvilke begrensninger som finnes mhp vanndyp, kaier, tilgang til utstyr etc. The bottom pontoon construction 6 is preferably constructed of concrete, which provides a strong and rigid construction so that the bucket cells 12 can be free-standing without bracing at the top. The floating, semi-submersible hull 1 according to the present invention results in a very simple and clean floating construction which, in addition to good behaviour, robust properties in relation to strength and fatigue, maintenance-free etc. also provides good conditions during construction as the hull 1 can be completed by berth and float on bottom pontoon structure 6 with small draft including turbine mounted. The floating, semi-submersible hull 1 thus only requires very simple mechanical equipment as, after towing and during installation, water is sluiced into the pontoon and connected to the sea, and the only thing that needs to be checked during the operation is the water levels in nodes under the bucket cells 12 and the tower 3, which is removed using bilge pumps. Finally, it should be mentioned that the floating, semi-submersible hull 1 can be built in different materials, for example in solid concrete or as a "hybrid". A hybrid solution with bucket cells 12 in steel, i.e. from level top bottom pontoon construction 6, provides a lighter construction and thus reduces the minimum draft during towing as well as in operation compared to an all-concrete design. The choice of material will depend on where the floating, semi-submersible hull 1 is built and what limitations there are regarding water depth, quays, access to equipment etc.
