Abstract

U ovom završnome radu je proveden proračun stabiliteta pučinske plutajuće vjetroelektrane u
neoštećenom stanju po pravilima Det Norske Veritas-a (DNV). U obzir su uzeta pravila koja
se odnose na metode proračuna stabiliteta te kriteriji koje pučinska plutajuća vjetroelektrana
mora zadovoljiti vezano za prekretni moment uzrokovan vjetrom. Sam model izrađen je najprije
u Rhinoceros-u, a zatim je uređen i pripremljen za proračun stabiliteta u Maxsurf-u. Pučinska
plutajuća vjetroelektrana ima jedno stanje krcanja za koje se provjeravao stabilitet, ali za više
smjerova puhanja vjetra. Nakon što smo utvrdili da je stabilitet zadovoljen, napravljena je
optimizacija forme. Na kraju je dan zaključak o rezultatima proračuna.

Abstract (english)

This final paper includes the stability calculation of an offshore wind turbine in intact
conditions. The rules are given by Det Norske Veritas (DNV). Stability evaluation will be
guided by the rules. Rules will give stability criteria for the offshore wind turbine, which must
be met for righting and heeling moment. The model was created in Rhinoceros software and
was later imported into Maxsurf software for stability evaluation. The offshore wind turbine
has one load case for which we will do stability evaluations. Wind will be superimposed from
many directions. After the stability criteria were met, the form of the semisubmersible platform
was optimised. The conclusion was given regarding the calculation results.
