SACS Advanced Analysis Modules

They are specialized individual add-on modules for the SACS software that allow engineers to perform complex analyses beyond standard capabilities. These modules include SACS Collapse (for accidental events), SACS Fatigue Ultimate (for long-term lifespan), and SACS Pile Structure Design (for foundation integrity).

Choose the module based on your specific challenge. Use SACS Collapse to analyze sudden, extreme events like a ship collision. Use SACS Fatigue Ultimate to predict the long-term effects of environmental wear for waves and wind. Use SACS Pile Structure Design to ensure the stability of the foundation.

No, they are integrated add-ons that require a core SACS software license. They are fully compatible with SACS Offshore Structure Ultimate and are also included as part of the comprehensive SACS Wind Turbine package.

Yes, they are essential for both new designs and existing assets. They can be used to assess the residual strength of a damaged platform, perform life extension studies, or re-evaluate foundation capacity as part of a structural integrity management program. 

The detailed analyses from these modules provide the engineering proof needed to demonstrate that a structure meets the stringent safety, lifespan, and stability requirements of major international design codes like API, ISO, and DNV.

Fatigue is the cumulative damage a structure experiences from repeated, cyclical loads, like a paperclip breaking after being bent back and forth. For an offshore platform, these loads come from decades of constant wave action and wind. Fatigue analysis is the process of simulating these long-term environmental effects to calculate the structure's expected service life and ensure it is designed to last safely without critical failures from long-term wear and tear.

Progressive collapse analysis is a simulation that answers the question, "What happens if a critical part of the structure is suddenly damaged?" It assesses whether an initial failure—caused by an extreme event like a ship collision, dropped object, or blast—would cascade, causing the entire structure to fail. This analysis is crucial for designing robust structures that can absorb accidental damage without leading to a catastrophic, disproportionate collapse.
