Abstract

By development of ship dimensions and the necessity of berthing of high tonnage ships, there was a need for an appropriate structure with optimum energy absorption behavior. Since the conventional berthing facilities (such as quays, sheet piles, etc.) could not experience large displacements, absorbing a large amount of energy by them is satisfied by applying high forces. Besides, due to the high drought of big ships, providing the proper depth for berthing of these ships will cost a lot. All above discussions have led the designers to use an appropriate structure in deep water that in addition to absorbing energy through experiencing large displacement, the repairing cost of that be independent to the other facilities. The most appropriate structure fulfilling this purpose is the monopile. Because of high forces exerted on monopile, the large displacement will occur in the surrounding soil which makes the soil behavior nonlinear. In addition, presence of water around the structure and also dynamic behavior of ship impact phenomenon makes the analysis complicated. In this paper in order to satisfy the above mentioned parameters, and to consider the water-structure-soil interaction, Ansys7.0 is used and based on the obtained results, the design curves have been extracted in such a way that the dimension of monopile could be obtained via them by having soil characteristics, water depth, ship tonnage and its velocity as input.
