ANSYS ASAS
 

ASAS is an offshore structural finite element system with integrated modules to address the specific needs of offshore and marine engineers. It provides an integrated facility for performing structural assessment of most types of offshore/marine structures including jackets, jack-ups, concrete gravity-based platforms, risers, FPSOs, TLPs, semi-submersibles and, of course, ships.

Two packages are available. ANSYS ASAS provides a general purpose analysis capability with linear and nonlinear options including code checks for framed structures (i.e., joint checks and member checks). ANSYS ASAS Offshore extends ANSYS ASAS to include modules for wave loading, soil-pile-structure interaction and spectral fatigue due to wave, current and wind loading. Model creation can be performed via ANSYS® or with FEMGV®.

ANSYS ASAS is highly appreciated because of the following distinguishing capabilities, including:

  • Coupled wave/current/wind-structure interaction with nonlinear structural response
  • An integrated results database which can be accessed by MS-EXCEL© and Mathcad©
  • Deterministic and spectral fatigue analysis capabilities (e.g., for jackets and flare towers)

 
 
  Product Features  
Model Generation
Model generation through the ANSYS Mechanical Products or Femgv
 
Code Checking and Fatigue Calculations
Provides capabilities to undertake checks against the most commonly used codes
Non-Linear and Extended Solution Capabilities
Provides a standard set of features that would be required for going beyond simple linear elastic analysis
 
Interfaces to ANSYS AQWA
Pressures and motions from a diffraction/radiation analysis in ANSYS AQWA can be transferred to an ASAS model
Coupled Wave Structure Interaction with Regular and Random Waves
Integrates the wave loading capabilities with the large deflection solver available in the non-linear product
 
Direct Access of ASAS Results from MS-EXCEL© and Mathcad ©
Results can be accessed and retrieved using MS-EXCEL and Mathcad
