Analysis of Breakwater Reconstruction Alternatives, ACI Marina, Rovinj

Unutar ovog diplomskog rada analizirani su objekti predviđeni za obranu privezanih plovila u luci od nadolazećih valova. Analiza objekata za obranu od nadolazećih valova se provodi s ciljem pronalaska odgovarajuće zamjene postojećem lukobranu, u ACI marini Rovinj, koji trenutno ne zadovoljava uvjete sigurnosti zbog prevelike agitacije valova ispod konstrukcije lukobrana, što rezultira štetom na privezanim plovilima. Analiza se provodi za tri varijantna rješenja zamjene postojećeg lukobrana: pontonski lukobran, kompozitni lukobran i lukobran na pilotima. Prilikom provođenja analize, u obzir su uzeta sva moguća vanjska djelovanja na lukobran, s ciljem dobivanja što preciznijih rezultata analize. Svako varijantno rješenje zamjene postojećeg lukobrana u ACI marini Rovinj je detaljno opisano i dimenzionirano. Sva tri varijantna rješenja su uspoređena s ciljem odabira optimalnog rješenja koje zadovoljava sve uvjete sigurnosti, te ima najmanji utjecaj na cirkuliranje morske mase i na krajobraz.The main idea of this study was to analize the objects that are provided for defense of boats and ships in harbour, from upcoming waves. The analysis of defense objects is carried out with goal to find the appropriate replacement for current breakwater, in ACI marina Rovinj. The current breakwater does not meet the safety terms and conditions, becouse of enormous wave transmition under the breakwater construction, wich resoults with damadged boats inside the marina. The analysis is carried out for three solutions for replacing the existing breakwater: pontoon breakwater, composite breakwater and pile breakwater. During the analysis it has been taken into account that all posible exterior effects may affect the analysis. Each replacement for existing breakwater in ACI marina Rovinj is described in detail and dimensioned. All three solutions are compared with goal of choosing the optimal solution wich satisfies all safety terms and conditions, and has the smallest effect on nature
