The context

Understanding
the assignment.

Nautilus Dynamics teams brought together hose-system analysis, seabed interfaces and the design of associated steel structures and foundations.

Challenges

  • Connect hose response, fatigue and seabed stability with the loads used for structural and foundation design.
  • Carry soil interpretation, connections and corrosion protection through to fabrication details.
Nautilus Dynamics’ contribution

Our engineering scope.

  • Hydrodynamic, fatigue and on-bottom stability analysis.
  • Soil investigation, interpretation and foundation design.
  • Structural verification, finite element analysis, weld and bolting checks.
  • Cathodic protection design.
  • 2D and 3D modelling and fabrication drawings.
