ANSYS AQWA addresses the vast majority of analysis requirements associated with the hydrodynamic assessment of all types of offshore/marine structure 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 the primary hydrodynamic parameters required for undertaking complex motions and response analysis. Model creation can be performed through a connection with ANSYS DesignModeler with the new AQWAWB application or via ANSYS Mechanical tools using a provided ANSYS APDL macro. Hydrodynamic analysis results (i.e., motions and pressures) can be transferred to 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 the frequency and/or time domain. More advanced requirements, such as dynamic position systems and energy dissipation can be accomplished through a User Defined Function.
