ANSYS Aqwa software addresses the vast majority of analysis requirements associated with hydrodynamic assessment of all types of offshore and marine structures. These include SPARs, FPSOs, Semi-submersibles, Tension leg platforms, Ships, Renewable energy devices, and Breakwaters.

Aqwa has been used extensively in the oil & gas, renewable and general engineering sectors to model installation and use of equipment in open water as well as in harbors or sheltered locations.


ANSYS Aqwa comprises two packages:

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 ANSYS DesignModeler software 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.
