SACS FATIGUE ULTIMATEFatigue Life Evaluation And Redesign Software
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.
WHY SACS FATIGUE ULTIMATE?
Assess Fatigue LifePerform 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 WorkflowsManage 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 CodesEnsure 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.

INTERACTIVE FATIGUE
Fatigue with Wave Response and Dynamic Response
This package contains the modules required to perform any dynamic deterministic, time history, or spectral fatigue analysis. It also includes modules for general dynamic and seismic analyses. SACS Fatigue Ultimate contains SACS Fatigue, Interactive Fatigue, Dynamic Response, and Wave Response. It requires the use of the SACS Offshore Structure, Offshore Structure Advanced, or Offshore Structure Ultimate.
– Supports full 3D geometry and section properties
– Allows SACS model files to be ported directly to a PDMS macro file, which creates the 3D model in PDMS
– Supports PDMS section libraries in addition to creating PDMS sections defined in the SACS model
– Logging functionality
– ISM Export to ProSteel and other steel detailing systems
– Integrated with ProjectWise for sharing all projects files across multiple sites
Fatigue Life Evaluation and Redesign
– Spectral, time history, and deterministic fatigue analysis
– Cyclic stress range calculation procedures include wave search,
curve fit, and interpolation
– SCF calculations recommended by API (including 21st edition
supplements), HSE, DNV, DS449, and Norsok Codes
– Automatic redesign
– API (including 21st edition supplements), ISO 19902, AWS, HSE, and Norsok thickness dependent recommended S-N curves
– Multiple run damage accumulation
– Pierson-Moskowitz, JONSWAP, Ochi-Hubble double peak, simplified double peak, and user-defined spectra
– Automated or user-specified connection details
– Pile fatigue analysis
– Creates wave spectra from scatter diagram
– Uses Paris equation to predict crack growth rate due to cyclic stresses
– Load path dependent joint classifications
– Includes wave spreading effects
– Reservoir (rain flow) cycle counting method
INTERACTIVE FATIGUE
– Shows the 3D view of the connection and allows braces to be selected with the mouse
– Reads connection defaults when joint and/or brace is/are selected, thus eliminating the need to calculate and display SCFs before viewing capacity or modifying properties
– Recognizes all SCF and S-N options available in the batch program
– Allows SCF theory to be changed for any type of connection, including inline connections and connections with user-defined SCFs
– Reports have been expanded and reworked to make them easier to read
– Reports and plots can be displayed on the screen and/or saved to a file
– Automatic redesign
SACS Fatigue Ultimate includes SACS Fatigue, SACS Advanced Dynamic Response, and SACS Advanced Wave Response.
“SACS software and its tailor-made enhancements is a very useful tool for structural integrity engineers where a quick workable solution is required in the shortest possible time.”
