Floating Offshore Structure Solutions
Proven Technology for Design and Analysis of Mobile Offshore Structures
Diffraction/Radiation 3-D panel method
Offshore projects today require that the design and analysis of these structures are performed efficiently in terms of time and money. Engineering simulation software
must be powerful, fast and user-friendly. ANSYS
Multi-body diffraction and radiation Forward speed
® ™ Full QTF matrix calculation
AQWA technology is the desired engineering hydrodynamic simulation tool for the offshore and marine community.
Import of external data
ANSYS AQWA Diffraction provides an integrated facility for developing the primaryhydrodynamic parameters required for undertaking complex motions and response
analysis. Three-dimensional linear radiation and diffraction analysis can be undertaken with multiple bodies, taking full account of hydrodynamic interaction
effects that occur between bodies. Although the software is designed primarily for
floating structures, fixed bodies can be included in the models, such as breakwaters
or gravity-based structures. Computation of the second-order wave forces via the
full quadratic transfer function matrices permits use over a wide range of water
depths.
