Offshore Floating System Hydrodynamic Assessment

A floating offshore support system was evaluated within the ANSYS Civil & Offshore workflow, using Aqwa-style hydrodynamic loading for maritime response and downstream structural checks for deformation, stress and strain.

Step 01

Geometry and High-Quality Meshing

The floating turbine support and tower interface were prepared with a refined mesh so the hydrodynamic load transfer and structural response could be evaluated with stable result contours.

Step 02

Hydrodynamic Wave Pressure Mapping

Wave conditions were applied to the offshore support to identify pressure distribution over the wetted structure. The mapped pressure field provides the loading basis for later structural verification.

Step 03

Total Deformation Response

The deformation result highlights how the floating support and tower deflect under combined wave-driven loading. This check helps confirm serviceability and global platform stiffness.

Step 04

Structural Stress Check

Equivalent stress contours were reviewed around the hull, tower connection and support regions to locate demand concentrations caused by offshore wave action.

Step 05

Strain and Safety Interpretation

The strain result completes the offshore assessment by showing local response under the hydrodynamic load case, supporting judgement on structural safety and design refinement.

Civil Composite Beam Static Load FEA

A civil steel-concrete simply supported beam was modelled with ANSYS Structural to study static load behaviour, material-grade effects and the influence of reinforcement layout on Von Mises stress and total deformation.

Step 01

Full Beam Geometry

The numerical model represents a simply supported composite beam made from concrete and internal steel reinforcement. The geometry provides the basis for comparing material grades and reinforcement configurations.

Step 02

Steel Reinforcement Layout

The steel bars were arranged inside the concrete body to control flexural rigidity and moment of inertia. This layout is central to the comparison of beam stiffness and deformation.

Step 03

Finite-Element Mesh

The beam was discretised with finite elements to resolve stress and deformation through the steel-concrete system, including the load path from the pressure zone to the support points.

Step 04

Loads and Supports

Static pressure loading and simply supported boundary conditions were applied to reproduce the bending response of the composite beam under central load action.

Step 05

Stress and Crack-Ignition Response

Principal stress and equivalent stress contours were used to locate critical response regions and identify where crack initiation or high local stress may occur under the applied static load.

Step 06

Material Grade and Inertia Comparison

The study compares structural steel, high-carbon steel and low-carbon steel, then tests a higher-inertia reinforcement layout to reduce stress and deformation in the beam model.
