Abstract	In order to get better understanding on the response of floating bodies, different design aspects of mooring lines has been investigated in this paper. Mooring lines are categerized into two types; the catenary settling on the sea floor (type 1) and the limited one which has no dead-length on sea floor (type 2). It has been observed that the stiffness of both types may be well predicted by Jain’s formulation and in the design process of floating bodies the mooring lines may be replaced by uncoupled horizontal and vertical springs. On the other hand, the anchor capacity against sliding and release from the mean still water has been studied in this paper. From the results of a parametric study, using the discrete element method, the block anchor the dimensions for the Urmia floating bridge has been optimized and the behavior of anchor and seabed deposits for release of block anchor indicates that the burial depth and the stress level on the block anchor itself and the sea bed are in the allowable and elastic region, respectively.
