A 3-D discrete element method is developed as a simple tool to analyse the contact stresses between rigid structures (such as off-shore subsea structures, cylindrical skirt foundations or suction anchors, caissons and so on) and the surrounding soil as well as soil bearing capacity under applied loads. The structure is divided into a number of small discrete elements, defined by their position, orientation and geometry, rigidly connected at the structure centre. The soil-structure interaction is modelled by non-linear springs. The method is incorporated into a PC, Fortran program — DISEL. The structure geometry, the displacements and the resulting contact stresses at discrete element centres are displayed graphically by a post-processor Visual Basic program. The use of the program in designing and analysing the subsea structures is exemplified with a levelling analysis for a North Sea Template Foundation Structure in order to estimate the required levelling forces.
