Theoretical background

The analyses performed with DeepLines are at the interface of many different disciplines and so a range of problems have to be dealt with :

  • Equations of motion: this section provides details on the global coordinates system and virtual works principle.

  • Lines modelling: this section provides details on modelling of the structural behaviour, material behaviour laws.

  • Contacts modelling: this section provides details on seabed contact, clashing between lines.

  • Hydrodynamics: this section provides details on wave and current definition, floating unit motion, hydrodynamic loads on the lines, hydrodynamic interference in an array, coupling between the floating unit and the lines, vortex induced vibrations...

  • Fatigue damage: this section provides details on fatigue damage derivation methods.

  • Structural Code Check: this section provides the references of the structural code checks computations.

  • Numerical: this section provides details on finite elements modelling, algorithms and convergence criteria.
