What is SACS Fatigue Ultimate? SACS Fatigue Ultimate is a fatigue life evaluation and redesign software for the offshore industry. SACS Fatigue Ultimate lets you design for safety by analyzing the effects of cyclic stresses on your offshore structures. The software includes both wave response and dynamic response for simulation of dynamic wave and seismic forces.  Assess Fatigue Life Perform a variety of analyses to determine fatigue life from all angles. Analyze the life of your offshore structures using full nonlinear soil and structural analysis, dynamic spectral/time history fatigue analysis, spectral wind fatigue calculations, and damage assessments for wave action over time. Automate Workflows Manage multiple analyses with customizable templates within a common structural model. Automatically pass data from one analysis step to another. These automated workflows simplify the management of large and complex models, so you can explore more design options. Comply With Design Codes Ensure structural compliance using built-in checking and filter results for critical conditions. Optimize design and configuration for compliance to numerous current and past international codes.
