Claims (12)
1. Fremgangsmåde (100) til at anvende stedspecifik data til at bestemme, om et spidselement (154, 160) skal installeres på et rotorblad (22) af en vindmølle (10), hvilken fremgangsmåde omfatter: at monitorere (102) med en sensor i det mindste et vindforhold på et vindmøllested (24); at bestemme (104) en faktisk spidsafbøjningstærskel (144) af et rotorblad (22) af en vindmølle (10) placeret på vindmøllestedet (24) baseret på det mindst ene vindforhold; at sammenligne (106) den faktiske spidsafbøjningstærskel (144) med en forudbestemt spidsafbøjningstærskel (150) af rotorbladet (22); og at bestemme (108) om et spidselement (154, 160) skal installeres på rotorbladet (22) baseret på sammenligningen mellem den faktiske spidsafbøjningstærskel (144) og den forudbestemte spidsafbøjningstærskel (150).
2. Fremgangsmåde (100) ifølge krav 1, hvor monitorering med en sensor af i det mindste et vindforhold på et vindmøllested (24) omfatter at måle med en vindhastighedssensor (148) en vindhastighed på vindmøllestedet (24).
3. Fremgangsmåde (100) ifølge krav 1, yderligere omfattende at analysere det mindst ene vindforhold for at bestemme et maksimalt vindforhold for vindmøllestedet (24).

7. Fremgangsmåde (100) ifølge krav 6, hvor bestemmelse af om et spidselement (154, 160) skal installeres på rotorbladet (22) baseret på sammenligningen mellem den faktiske spidsafbøjningstærskel (144) og den forudbestemte spidsafbøjningstærskel (150) omfatter at bestemme om spidselementet (154, 160) skal installeres baseret på eksistensen af afbøjningsmarginen (152).
8. Fremgangsmåde (100) ifølge krav 7, yderligere omfattende at installere en sugeside anbragt lille vinge (154) på rotorbladet (22) baseret på afbøjningsmarginen (152).
9. Fremgangsmåde (100) ifølge krav 8, hvor en højde af den sugeside anbragte lille vinge (154) er lig med eller mindre end afbøjningsmarginen (152).
10. Fremgangsmåde (100) ifølge krav 7, yderligere omfattende at installere en spidsforlængelse (160) på rotorbladet (22) baseret på afbøjningsmarginen (152).
11. Fremgangsmåde (100) ifølge krav 1, hvor den forudbestemte spidsafbøjningstærskel (150) er lig med omkring 70 % af en statisk tårnsikkerhedsafstand af vindmøllen (10).
12. Fremgangsmåde (100) ifølge krav 1-8, hvor spidselementet (154, 160) er en sugeside anbragt lille vinge (154).
