Abstract

Udviklingen af nye teknologier samt forbedringer af eksisterende teknologier inden- for vedvarende energi bliver støttet af indflydelsesrige politikere, økonomisk stærke virksomheder og fonde. Denne politiske og industrielle støtte er især udbredt i Nordeuropa. Offshore vindenergi er en bæredygtig energiform og en i høj grad uudnyttet energiressource. Produktionspriserne for nye havvindmøller har efterhånden nået et niveau, hvor offshore vindenergi er konkurrencedygtig i forhold til andre former for vedvarende energi. Optimering af teknologien inden for offshore vindenergi er derfor særdeles vigtig, for at bryde afhængigheden af fossile brændstoffer samt for at møde fremtidens energi- og klimamål.

Omkostningerne forbundet med funderingen af havvindmøller udgør typisk 20-30 % af de samlede omkostninger for havvindmøller. Dermed kan forbedringer af de nuværende designmetoder for funderingen af havvindmøller være med til at øge konkurrenceevnen for offshore vindenergi væsentligt.
Den mest anvendte funderingstype for offshore vindmøller er monopæle.
Det overordnede mål med denne afhandling er at optimere de nuværende designmetoder for monopæle fundamenter, således at konkurenceevnen for offshore vindmøller kan forbedres. Derfor er interaktionen mellem jord og pæl blevet undersøgt for stive offshore pæle.
