The computerization of pipeline design is relatively important for the engineering feasibility of submarine pipelines. The changing environmental conditions make difficulties for the stability calculation of each pipe segment on line. For this reason, the computer study will provide many advantages during the design of pipeline. The different environmental and functional parameters can be easily tried on line and the most suitable size of structure against the extreme environmental conditions can be determined.

This study deals with the general design principles especially including the engineering studies, i.e. wave statistical analysis, transformation of waves, stability analysis, and developed computer program to achieve both the stabilization of pipeline and aid for drawing the route together with user in some stages of the design.

Finally, the outline of the program is briefly described and a flow chart is presented.
