Abstract

Prema idejnom rješenju marine Sobra za sidreni sustav plutajućih pontona odabran je Seaflex sustav. Seaflex sustav se zasniva na homogenim elastičnim gumenim kablovima koji imaju zadatak preuzeti horizontalna opterećenja od vjetra i valova. Cilj ovog proračuna je određivanje dokaznice mjera sastavnih dijelova sidrenog sustava i dobivanje nacrta sidrenog sustava. Za proračun projektnih valova korištena je Groen–Dorrenstein metoda. Rad sadrži i proračun opterećenja vjetra na plovila i valova na gatove, pri čemu je korištena jednadžba za otpor fluida kod vjetra i jednadžba za silu zanošenja kod valova. Proračun ovog sidrenog sustava daje uvid u broj gumenih kablova, dužine poliesterskih užadi i težinu sidrenih blokova kao njegovih sastavnih dijelova. Nadalje, on omogućava izradu nacrta koji opisuje smještaj sidrenog sustava u akvatoriju marine. Proračun je od iznimne važnosti kako bi se omogućila funkcionalnost same marine i siguran privez plovila na plutajuće pontone.

Abstract (english)

According to conceptual design of the marina Sobra for mooring system of the floating pontoons, Seaflex system has been chosen. Seaflex system is based on homogen elastic rubber hawsers which are responsible for taking over horizontal load of wind and waves. Purpose of this calculation is determining bill of quantities of essential parts of the mooring system and layouts of the mooring system. For the calculation of design wave, Groen–Dorrenstein method is used. This paper contains calculation of the wind load on boats, and wave loads on pontoons. which is measured by the equation for fluid resistance at wind, and equation for drift force at waves. Calculation of this mooring system provides a number of rubber hawser needed, length of polyester rope and weight of anchor blocks as his essential parts, also it provides layouts that describe its position in aquatorium of the marina. Calculation is of significant importance so that functionality of the marina and safe mooring of the vessel on the pontoons is accomplished.
