Abstract

Tema ovoga završnoga rada je projektiranje konstrukcije pontona 15 MW plutajuće vjetroelektrane [1]. U prvoj fazi dimenzionirana je oplata i elementi orebrenja prema pravilima klasifikacijskoga društva Det Norske Veritas (DNV) [5] na temelju osnovnih geometrijskih značajki pontona. Dobivene dimenzije korištene su kao ulazni podaci prilikom modeliranja 3D modela u drugoj fazi. U drugoj fazi modeliran je 3D model u računalnom sustavu FEMAP [4], a nakon toga provedena je analiza pomoću metode konačnih elemenata (MKE) u računalnom sustavu MAESTRO [3]. Nakon definiranja tri slučaja opterećenja provedena je analiza odziva prototipne konstrukcije čiji je rezultat ukazao nepodobnost određenih elemenata konstrukcije kao i nezadovoljavanje kriterija dopuštenih naprezanja. U trećoj fazi provedeno je djelomično redimenzioniranje konstrukcije te je dan prijedlog kako bi konstrukcija mogla zadovoljiti kriterije podobnosti i naprezanja.

Abstract (english)

The subject of this project is a structural design of floating support pontoon for an offshore wind turbine. First designing phase, based on elementary geometrical characteristics, includes defining construction elements according to the Det Norske Veritas (DNV) [5] classification society. Dimensions obtained in this phase are used as base data for the second phase. Second designing phase consists of creating 3D FEM model of prototype in software FEMAP [4] and then the 3D FEM model was transferred in software MAESTRO [3] in order to conduct a finite element method structural analysis. Analysis response of the prototype model, which was done after defining three load cases, indicated inadequate structural elements as on the deviation of permissible stresses. Based on those results, a suggestion was made so that the structure could meet adequacy and stress criteria.
