USFOS is a leading computer program for nonlinear static and dynamic analysis of space frame structures. USFOS is used by leading oil companies and engineering consultants world wide, for integrity assessment, collapse analyses and accidental load analyses of offshore jacket structures, topsides, jack-ups and other frame structures, intact or damaged.

The program accurately simulates the collapse process, from the initial yielding, through to the formation of a complete collapse mechanism and the finale toppling of the structure. The program has proved significant cost savings in areas such as inspection planning, lifetime extension / reassessment of ageing structures, and in fire protection assessment for new designs.

USFOS is cost effective, design oriented and easy to use. The program has a simple input structure and requires little specialized knowledge on nonlinear finite element analyses.
