Claims (13)

1. Fremgangsmåde til optimering af vægten af en vindturbinekonstruktion, hvilken vindturbinekonstruktion omfatter en vindturbine tilvejebragt på et offshorefundament, hvori vindturbinen omfatter en rotor med mindst to vindturbineblade og et rotomav, hvor vindturbinen yderligere omfatter vindturbinetåm, hvor fremgangsmåden omfatter trinene: - tilvejebringelse af vindturbinen med en afstand mellem det nominelle havniveau og den laveste position af en spids ende af vindturbinevingerne under rotation, som er lig med eller mindre end 25 meter, - måling af mindst en bølgehøjde i forhold til et nominelt havniveau, - drift af vindturbinen, f.eks. rotoren og/eller vindturbinevingerne, i henhold til den målte bølgehøjde, - placering af rotoren i en parkeret stilling i forhold til vindturbinetårnet, kendetegnet ved, at rotoren parkeres med en maksimal frihøjde mellem de mindst to vindturbinevinger og havniveauet, hvis i det mindste den målte bølgehøjde overstiger en forudbestemt tærskel.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at fremgangsmåden yderligere omfatter bestemmelse af et forhold mellem en vingelængde af vindturbinevingerne og en tåmhøjde af vindturbinetårnet, hvor vindturbinens forhold er større end 0,5.
3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at vindturbinen køres i normal driftstilstand, hvis den målte bølgehøjde er lig med eller under tærsklen.
4. Fremgangsmåde ifølge ethvert af de foregående krav, kendetegnet ved, at den forudbestemte tærskel er 18 meter eller mindre, fortrinsvis mellem 5 og 15 meter.
5. Fremgangsmåde ifølge ethvert af de foregående krav, kendetegnet ved, at vindturbinen drives i en nedlukket tilstand, hvis den målte bølgehøjde er over tærsklen, hvor rotoren enten parkeres i en stilling med en maksimal frihøjde mellem vindturbinevingerne og havniveauet eller i en stilling med minimal frihøjde mellem vindturbinebla-dene og havniveauet.
6. Fremgangsmåde ifølge krav 5, kendetegnet ved, at fremgangsmåden yderligere omfatter overvågning af et forudbestemt område i forhold til offshorefundamentet, hvor vindturbinen yderligere drives i nedlukket tilstand, hvis der registreres mindst en bevægelig genstand indenfor dette område.

8. Vindturbinekonstruktion omfattende: - en offshorefundament konfigureret til at installeres på et installationssted, hvilket offshorefundament omfatter en installationsgrænseflade til en vindturbine, - vindturbinen omfatter et vindturbinetårn konfigureret til installering på offshorefundamentet, en maskinkabine ovenpå vindturbinetårnet og en rotor roterbart monteret på maskinkabinen, hvilken rotor omfatter mindst to vindturbinevinger monteret på et rotomav, hvor vindturbinen yderligere omfatter en styreenhed konfigureret til at styre vindturbinens drift, hvori - mindst en måleenhed er konfigureret til at måle en bølgehøjde i forhold til et nominelt havniveau, hvilken måleenhed er konfigureret til at kommunikere med styreenheden, kendetegnet ved, at vindturbinen er yderligere konfigureret til at placere rotoren i parkeret stilling med en maksimal frihøjde mellem de mindst to vindturbineblade og havniveauet, hvis den målte bølgehøjde overstiger en forudbestemt tærskel, hvori afstanden mellem det nominelle havniveau og den nederste position af en spids ende af vindturbinebladene under rotation er lig med eller mindre end 25 meter.
9. Vindturbinekonstruktion ifølge krav 8, kendetegnet ved, at offshorefundamentet er et flydende fundament.
10. Vindturbinekonstruktion ifølge krav 8 eller 9, kendetegnet ved, at måleenheden er arrangeret på vindturbinekonstruktionen eller placeret i forhold til offshorefundamentet.
11. Vindturbinekonstruktion ifølge ethvert af krav 8 til 10, kendetegnet ved, at vind-turbinekonstruktionen yderligere omfatter mindst en overvågningsenhed konfigureret til at overvåge et forudbestemt område i forhold til offshorefundamentet, hvori overvågningsenheden er konfigureret til at registrere en eller flere bevægelige genstande indenfor dette område.
12. Vindturbinekonstruktion ifølge ethvert af krav 8 til 11, kendetegnet ved, at vind-turbinekonstruktionen er konfigureret til at fungere i en normal driftstilstand, hvis den målte bølgehøjde er under tærsklen, eller hvis der ikke modtages noget styresignal fra overvågningsenheden.
13. Vindturbinekonstruktion ifølge ethvert af krav 8 til 12, kendetegnet ved, at vindturbinen omfatter tre vindturbinevinger.
