SØKNAD OM PATENT APPLICATION FOR PATENT

TITTEL: HAVVIND VINDMØLLE MED FORANKRING RETT UNDER TITLE: SEA WIND WINDMILL WITH ANCHORAGE JUST BELOW

PATENTKRAV PATENT CLAIMS

1. Hovedkrav er forankring av kolonne med vindmølle rett under eller straks ved rett under kolonnen. 1. The main requirement is the anchoring of the column with the wind turbine directly below or immediately next to the column.

2. Som tilleggskrav gjelder en horisontal plate dypt nede som vil hindre store veryikale bevegelser på overflaten for systemet. 2. As an additional requirement, a horizontal plate deep down that will prevent large vertical movements on the surface of the system applies.

BAKGRUNN BACKGROUND

Dagens flytende vindmøller på havet som produserer strøm, har normalt store ankersystemer for å sikre møllenes posisjon. De er også store konstruksjoner som skal klare og motstå de belastninger som kommer fra strøm, vind og bølger. Ankersystemene er lite ønskelig både for det arealet de okkuperer og for de eventuelle blokkeringer det gir for fiske og for andre installasjoner i nærheten. Today's floating wind turbines at sea that produce electricity normally have large anchor systems to secure the turbines' position. They are also large structures that must cope with and withstand the loads that come from electricity, wind and waves. The anchor systems are not desirable both for the area they occupy and for the possible blockages they cause for fishing and for other installations in the vicinity.

Systemet som det her søkes patent på tar bort den omfattende forankringen. Systemet er også avbalansert slik at det vil være lettere enn de vanlige konstruksjonene som dekker dette behovet i dag. Derved er det mulig å forankre systemet rett under hvor konstruksjonen flyter. The system for which a patent is sought removes the extensive anchoring. The system is also balanced so that it will be lighter than the usual constructions that cover this need today. Thereby, it is possible to anchor the system directly below where the structure floats.

Ved at ovennevnte er tatt hensyn til blir også installasjonen av systemet enkelt. As the above is taken into account, the installation of the system is also easy.

BESKRIVELSE AV SYSTEMET DESCRIPTION OF THE SYSTEM

Systemet er vist i vedlagt skisse. The system is shown in the attached sketch.

- På topp av konstruksjonen er generatoren med vindmøllen plassert. - At the top of the construction is the generator with the windmill.

- Konstruksjonen på toppen er en søyle som inneholder en leider slik at personell kan komme opp til generator og vindmøller på toppen. Inne i søylen er også kraftkabelen som vil sende produsert strøm fra systemet og ned til koblingspunktet for kabelen som fører strømmen videre. - The construction at the top is a column that contains a ladder so that personnel can get up to the generator and wind turbines at the top. Inside the pillar is also the power cable that will send produced electricity from the system down to the connection point for the cable that carries the electricity on.

- Søylen ender nederst i en plattform som vil bli brukt for at personellet kan komme om bord i systemet. Plattformen er nedenfor betegnet som “entering plattform”. - The column ends at the bottom of a platform that will be used for the personnel to get on board the system. The platform is below referred to as "entering platform".

- Knyttet til entering plattformen vil det kunne komme håndtering og festeanordning for forankringen. I forbindelsen med enterings plattformen vil kabelen for eksport av strøm også bli festet. Derved kan dette gjøres uten at undervannsarbeider er nødvendig. - Attached to the entry platform will be handling and fastening devices for anchoring. In connection with the entering platform, the cable for exporting power will also be attached. Thereby, this can be done without underwater work being necessary.

- Under enterings platformen følger et område med mindre diameter. Denne mindre diameteren sikrer at bølgene har mindre struktur til å belastning på konstruksjonen med. Området vil også være avstand fra entering plattform ned til bølgesonen og videre ned til oppdriftstank. - Below the entering platform follows an area with a smaller diameter. This smaller diameter ensures that the waves have less structure to load the construction with. The area will also be the distance from the entry platform down to the wave zone and further down to the buoyancy tank.

- Oppdriftstanker følger. Denne er stor nok til å oppveie vekten av hele systemet i tillegg til å gi et trygt strekk for systemet for forankringen i bunnen. Sammen med de vektene som er plassert vil den også sikre at systemet til enhver tid er stabilt, også dersom konstruksjonen taues oppreist ut til feltet. Oppdriftstank vil ha vertikale kanaler som forankringen vil bli ført gjennom slik at denne ikke blir skjøvet ut over tankens ytterkant. - Buoyancy tanks follow. This is large enough to offset the weight of the entire system as well as providing a safe stretch for the system for anchoring at the bottom. Together with the weights that are placed, it will also ensure that the system is stable at all times, even if the structure is towed upright to the field. The buoyancy tank will have vertical channels through which the anchoring will be carried so that it is not pushed out over the outer edge of the tank.

- Fra oppdriftstank vil det gå et rør med tilstrekkelige dimensjoner som fører ned til en dempende plate. - From the buoyancy tank there will be a pipe of sufficient dimensions leading down to a damping plate.

- Den dempende platen blir plassert så dypt at den vil forhindre eller sterkt redusere de vertikale bevegelsene som kan komme basert på de kreftene som kan bli introdusert - The damping plate is placed so deep that it will prevent or greatly reduce the vertical movements that can occur based on the forces that can be introduced

Claims (1)

på overflaten. I tillegg til sin vekt vil den dempende platen trekke med seg mye vann ved enhver liten bevegelse, noe som også vil hindre vertikale utslag.on the surface. In addition to its weight, the damping plate will draw a lot of water with it at any slight movement, which will also prevent vertical impacts. - På den dempende platen blir det plassert en innretning som kan romme kjetting eller annet materiale som vil skape den tilstrekkelige stabilitet for systemet.- On the damping plate, a device is placed that can accommodate chain or other material that will create sufficient stability for the system. - Fra den dempende platen vil forankringen følge til bunnen. Det vil være enten kjetting eller vaier.- From the damping plate, the anchoring will follow to the bottom. It will be either chain or cable. - På bunnen vil det være vekter eller sugeankrer som vil gi systemet tilstrekkelig holdekraft slikl at systemet holder seg i posisjon. Med den avbalansering som er lagt inn i systemet vil denne kraften være relativ liten.- On the bottom there will be weights or suction anchors that will give the system sufficient holding power so that the system stays in position. With the balancing that has been added to the system, this force will be relatively small. INSTALLASJONINSTALLATION - Systemet vil bli ferdig laget innunder land. Det vil bli tauet ut stående i vannet eller transportert ut på feltet på lekter eller annet overflatefartøy.- The system will be completed underground. It will be towed out standing in the water or transported to the field on a barge or other surface vessel. - På feltet vil vekter eller sugeankre på bunnen bli installert på forhånd med kjetting eller vaier for forankringen lagt ut på bunnen. Kjettingen eller vaierne vil ha forbindelse til overflaten i form av tau eller vaier med bøye lagt ut. Det samme vil gjelde for elektrisk kabel, selv om den kan komme etter at systemet er installert.- In the field, weights or suction anchors on the bottom will be installed in advance with chain or wire for the anchorage laid out on the bottom. The chain or cables will have a connection to the surface in the form of ropes or cables with a buoy laid out. The same will apply to electrical cable, although it may come after the system is installed. - I konstruksjonen vil det på forhånd bli installert inntrekking kabler. Som er vaiere eller tau.- In the construction, pull-in cables will be installed in advance. Which are wires or ropes. - Konstruksjonens intrekkeings kabler og de som er festet til kjetting eller wire for forankringen vil bli ført sammen på overflaten av skip eller på enterings plattformen. - Forankringen blir trukket opp til sitt festepunkt oppe på konstruksjonen ved hjelp av de sammenkoblede inntreknings linene.- The structure's retracting cables and those attached to chain or wire for anchoring will be brought together on the surface of the ship or on the entering platform. - The anchorage is pulled up to its attachment point on top of the structure using the connected pull-in lines. MED DETTE ER KONSTRUKSJONEN PRODUSERT; INSTALLERT OG ER FERDIG FOR Å PRODUSERE. HEREBY THE CONSTRUCTION IS MANUFACTURED; INSTALLED AND READY TO PRODUCE.
