Abstract

Water transport is the cheapest and the oldest mode of transport. It operates on a natural track and hence does not require huge capital investment in the construction and maintenance of its track except in case of canals. During the last decades ships have grown larger and larger and the draft of the ship has also increased. Up to now, reliable, theoretically founded design criteria are hardly available. The lack of good design criteria is the prime reason for making researches into the possibilities of an experimental and theoretical determination of berthing forces. A jetty, two design vessels and four different types of fender systems are taken into consideration. The Berthing Energy is evaluated using IS:4651, BS:6349 and PIANC “Guidelines for Design of Fender Systems, 2002” for the largest and smallest vessel. The minimum Berthing Energy from the design vessels is obtained by using the three codes. Using the minimum Energy, the reactions developed for various fender systems is obtained. Based on those values, the fender system best suited for the jetty is found. Using those values, the Jetty is analysed and the Bending Moments developed in the structure for four fenders are considered. For modelling of jetty, STAAD.Pro is used.
