What outputs are generated by the analysis?

Analyses typically produce detailed CSV files containing shape and force data, along with interactive HTML plots for visual verification of the riser configuration.

Does it calculate pipe properties automatically?

The PipeProperties class calculates buoyancy, submerged weight, and effective weight based on steel dimensions and fluid/seawater densities.

Can I export my designs to OrcaFlex for dynamic simulation?

Yes, the skill includes an OrcaFlexModelBuilder that generates .yml files from calculated catenary configurations for easy import into OrcaFlex.

What types of risers can this skill analyze?

The skill supports both simple catenary risers and complex lazy wave riser configurations incorporating buoyancy modules.
