SACS is an integrated finite element structural analysis package of applications that uniquely provides for the design of offshore structures, including oil and gas platforms, wind farms, and topsides of FPSOs and floating platforms. SACS software has been used by offshore engineers around the world for nearly 40 years. Many of the world’s energy companies specify SACS software for use by their engineering firms across the lifecycle of offshore platforms. Because every project has different needs, there are three flexible SACS options. Offshore Structure Ultimate for comprehensive capabilities required for typical offshore jackets, wharfs, and dolphin structures; Offshore Structure Advanced for static topside and deck analysis; and Offshore Structure for static structural analysis.

The following modules are included with each license:

Offshore Structure contains capabilities required for static structural analysis. It includes the interactive graphics modeler with advanced 3D capabilities, SACS IV solver and interactive graphics 3D post-processor, Combine, Gap, Tow, and LDF large deflection. The package also includes automatic model generation, beam and finite element capability, steel code check and redesign, inertia and moving load generation, tension/compression nonlinear elements with initial gap, load case combination, linear large deflection analysis, and full output report and plotting capabilities.

Offshore Structure Advanced contains capabilities required for typical topside and deck analysis. It includes the interactive graphics modeler with advanced 3D capabilities, SACS IV solver and interactive graphics 3D post-processor, topsides wind loading, Combine, Gap, Tow, and LDF large deflection. The package also includes automatic model generation, beam and finite element capability, steel code check and redesign, wind and gravity load generation, inertia and moving load generation, tension/compression nonlinear elements with initial gap, load case combination, linear large deflection analysis, and full output report and plotting capabilities.

Offshore Structure Ultimate contains capabilities required for typical offshore jackets, wharfs, and dolphin structures. It includes the interactive graphics modeler with advanced 3D capabilities, SACS IV solver and interactive graphics 3D post processor, Seastate, Joint Can, Pile, Combine, Gap, Tow, and LDF large deflection. The package also includes automatic model generation, beam and finite element capability, steel code check and redesign, environmental load generation, tubular connection check, single pile/soil interaction, inertia and moving load generation, tension/compression nonlinear elements with initial gap, load case combination, linear large deflection analysis, and full output report and plotting capabilities. The package also contains the multicore analysis capability allowing the user to conduct multiple analyses of the same type in parallel, saving hours of runtime.

The following add-on modules can be combined with Offshore Structure Ultimate for comprehensive offshore capabilities:

Pile Structure Design - This nonlinear add-on package permits nonlinear soil/pile/structure interaction analysis of fixed offshore structures with multiple fixed supports using the PSI program modules. It requires
the use of the Offshore Structure, Offshore Structure Advanced, or Offshore Structure Ultimate package.

Collapse - Perform advanced nonlinear plastic analysis including pushover, ship impact, dropped object, and blast analysis. The Collapse Advanced program supports large deflections, large
rotations, arc length iterations, automatic sub-incrementations and torsional buckling. It requires the use of Offshore Structure, Offshore Structure Advanced, or Offshore Structure Ultimate package.

Fatigue Ultimate - This package contains the modules required to perform any dynamic deterministic, time history, or spectral fatigue analysis; DYNPAC, Fatigue, Interactive Fatigue, Dynamic Response and Wave Response. It requires the use of the Offshore Structure, Offshore Structure Advanced, or Offshore Structure Ultimate package.
