Structural analysis of steel structures
Onshore and offshore steel frames and structures, secured before fabrication.
Overview
We design onshore and offshore steel frames and structures: section selection, connection checks, support design and modification of existing structures.
Finite element analysis secures the real behaviour of the structure before any fabrication: stresses, deflections and stability are checked, then translated into fabrication and execution drawings.
Fields of application
- Offshore topsides and extensions
- Skids
- Portal frames and walkways
- Pipe racks and pipe supports
- Strengthening of in-service structures
- Mechanical parts
Our services
Finite element analysis
Stresses, deflections and stability of structures and mechanical parts.
Offshore
Topsides, skids, extensions and strengthening of in-service structures.
Steel frames
Portal frames, walkways, racks and pipe supports.
Connections
Checks of bolted and welded connections at the main nodes.
Modification of existing structures
Comparison between existing and new structure, checks of reinforcements.
Fabrication drawings
Fabrication and execution drawings coordinated with the study.
Our method
- 1
Data collection
Existing drawings, loads, site conditions and applicable codes.
- 2
Modelling
3D model of the structure, with its supports, loads and combinations.
- 3
Verification
Finite element analysis, checks of sections and connections.
- 4
Drawings and delivery
Fabrication and execution drawings, calculation note, handling of comments.
Deliverables
- Calculation note
- Fabrication drawings
- Execution drawings
- Section list and bills of materials
- 3D model of the structure
- Drawing files in DWG and PDF format
What you gain
- Behaviour verified before fabrication
- Fewer reworks in the workshop and on site
- Reinforcements sized as precisely as possible
- Drawings ready for fabrication

Frequently asked questions
Do you work on offshore structures?
Yes: topsides, skids, extensions and strengthening of in-service structures are part of our studies.
What does the delivered package contain?
A calculation note, the fabrication and execution drawings, and the 3D model of the structure.
Do you also study mechanical parts?
Yes: finite element analysis also applies to mechanical parts, from supports to complex assemblies.
