Structural Design

Structural design from Focus Engineering is carried out in accordance with the customers’ specifications and within the requirements of the applicable design standards. We always keep a strong focus on weight optimization and fabrication-friendly design.

Depending on the task, we use various CAD design tools. For larger structures our main software is Bentley ProSteel, whereas for smaller structures and/or mechanical design we use Onshape. All of our structural drawings are based on the structural 3D model, i.e. what you see in the model is what you will also find in the drawings.

For the structural analyses, we do all analysis work in-house. Beam models, such as topside modules, are analysed using SAP2000. Detail calculations and analyses for mechanical components are performed using ANSYS Workbench.

Based on the given design we decide what the appropriate type of analysis to used is. In addition to linear elastic analyses we also do non-linear material definitions, time/history analyses (typically for blast response analyses) and explicit dynamic analyses (impact).

For the most complex analyses we use our ANSYS license through the Rescale platform, which is a cloud-based service that lets us set up a high-performance virtual desktop in order to reduce the analysis time.
