Abstract
Radom glavnog stroja, brodskog vijka te ostalih brodskih strojeva, kao neželjena posljedica nastaje buka koja smanjuje ugodu na brodu, a u nekim slučajevima može ometati normalno funkcioniranje posade i putnika. Stoga je potrebno, kako bi se postigla što veća kvaliteta ugode za posadu i putnike, dovesti razinu buke u dozvoljene granice. U okviru ovog diplomskog rada izvršena je prognoza razine buke metodom hibridne statističke analize za istraživački brod za kružna putovanja u polarnim uvjetima za posebne namjene kapaciteta 200 putnika i duljine L_OA = 128 m. Za navedenu analizu korišten je komercijalni programski paket Designer-NOISE. Predstavljeni su osnovni pojmovi u brodskoj akustici te je prikazana zakonska regulativa koju zajedno definiraju Međunarodna pomorska organizacija (IMO) i klasifikacijska društva. Detaljno je opisan postupak izrade modela, i popis izvora buke koji su prisutni na brodu. U konačnici su dobiveni rezultati uspoređeni s proračunom razina buke koje je za isti brod, ali različitom metodom, provelo klasifikacijsko društvo Det Norske Veritas (DNV).
Abstract (english)
As an unwanted consequence, the operation of the main propulsion engine, the ship's propeller and other machinery, creates noise that reduces comfort on the ship, and in some cases can disturb the crew and passengers in their everyday activities. Therefore, in order to achieve the highest quality of comfort for the crew and passengers, it is necessary to keep the noise level within the specified limits. In this thesis, a noise level prediction calculation was made using the hybrid statistical energy analysis method for a research ship operating in polar conditions with a capacity of 200 passengers and a length of L_OA = 128 m. The commercial software package Designer-NOISE was used for performing the analysis. The basic terms in ship acoustics are presented and the legal regulations jointly defined by international organizations and classification societies are given. The process of making the model is described in detail, as well as the list of noise sources that are present on the ship. In the end, the obtained results were compared with the calculation of noise levels, which was carried out by Det Norske Veritas (DNV) for the same ship but using a different method.
