ANSYS Offshore Tools

The ANSYS Offshore Tools are specifically designed to meet the needs of offshore users, providing them with pre-processing, loading, solving, and post-processing solutions that are not available in general purpose simulation tools.  As part of the ANSYS, Inc. suite of products, the also offer unprecedented interoperability with other tools in the suite.

The primary ANSYS Offshore Tools are:


ANSYS Aqwa software addresses the vast majority of analysis requirements associated with hydrodynamic assessment of all types of offshore and marine structures, including:

  • SPARs
  • FPSOs
  • Semi-submersibles
  • Tension leg platforms
  • Ships
  • Renewable energy devices
  • Breakwaters
  • Two packages are available.

ANSYS Aqwa Diffraction provides an integrated facility for developing primary hydrodynamic parameters required to undertake complex motions and response analysis.  Model creation can be performed through a connection with ANSYS DesignModeler software (with the new hydrodynamic diffraction analysis system in ANSYS Workbench) or via other ANSYS structural mechanics tools using a provided ANSYS APDL macro.  Hydrodynamic analysis results, such as motions and pressures, can be transferred to ANSYS structural mechanics products, ANSYS ASAS or generically defined FE models for subsequent structural analysis.

ANSYS Aqwa Suite extends ANSYS Aqwa Diffraction to include analysis capabilities for global performance of moored and/or connected systems subject to random sea states.  Simulations may be static or dynamic in frequency and/or time domain.  More advanced requirements, such as dynamic position systems and energy dissipation, can be accomplished through a user-defined function.


ANSYS Asas software is a general-purpose structural finite element system containing industry-specific features to address the needs of offshore and marine engineers. ANSYS Asas provides the capabilities required to perform global structural assessment of most types of marine structures, including jackets, jack-ups, risers, offshore wind farms, and floating systems such as FPSOs, SPARs and semi-submersibles.
