Design of boat mooring system

Prilikom dimenzioniranja sustava priveza plovila dimenzioniraju se uređaji za privez (bitve, poleri, snopovi pilota) te se odabiru uređaji za ublažavanje i apsorbiranje kinetičke energije broda tzv. bokobrani (odbojnici, fenderi). Poleri i bitve se razlikuju po geometrijskom obliku i izrađuju se od lijevanog željeza koji se ispunjuje betonom, dok se snopovi pilota koriste u lukama velikih vodnih oscilacija. Uređaji za privez dimenzioniraju se na prekidnu silu najjačeg užeta broda za koji se dimenzionira vez. Uloga bokobrana je preuzeti i apsorbirati kinetičku energiju broda koji pristaje i držati brod na sigurnoj udaljenosti od obalne konstrukcije. Bokobrani se razlikuju po obliku, materijalu te faktoru bokobrana ( P/Ef) koji pokazuje koliko će energije bokobran apsorbirati, a koliku reakcijsku silu prenijeti na konstrukciju. Proračuni se zasnivaju na Britanskom standardu, preporci PIANC-a te Eurokodovima.At design calculatin of boat mooring system, the mooring facilities (cleats, bollards, and mooring dolphins) are designed and devices for cushioning and absorbing kinetic energy from the boats are chosen otherwise called fenders. Bollards are differentiated by geometric shapes and are made from poured iron which is then filled with concrete, while dolphins are used in harbours with large water oscillations. The mooring facilities are designed at the breaking force of the strongest rope of the boat whichberth is designed for. The role of the fenders are to take over and absorb kinetic energy of the boat that is docking and to keep the boat at a safe distance from coastline structures. Fenders differentiate in shapes, materials, and fender factor (P/Ef) which shows how much energy the fender will absorb, and how much of a reactional force it will transfer to the construction. Calculations are based on British standards and recommended by PIANC and Eurocodes
