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)
