Offshore

Accurate structural analysis is imperative to ensure the safe and economical design of offshore structures, which need to withstand heavy loads from fluid currents, waves, wind, and earthquakes. The interaction of risers and pipelines with their foundations and underlying soil also warrants serious consideration.  A range of material models along with special contact and loading conditions are required. Engineers must also perform fully nonlinear large displacement dynamic analyses to include time-dependent loads and structural response.

The Abaqus Unified FEA product suite from SIMULIA provides realistic simulation solutions for the Offshore industry that allow you to accurately predict structural strength and deformations in the large displacement nonlinear regime. Abaqus pre- and postprocessing technology coupled with its sophisticated solvers provide a complete and reliable solution for Offshore structural analysis. Static, modal, and dynamic analyses can be performed using a wide range of material models under different loading, boundary, and contact conditions. You may simultaneously include loads due to fluid currents with wave and wind loading, and you can compute detailed time-dependent responses for floating and non-floating Offshore structures.
