Inalia has contributed to the design, installation and data analysis of the monitoring system that measures aerodynamic and dynamic loads of Bound4Blue´s Suction sails for vessels.


To know real loads on the sail at the interface with the vessel structure. Analyse the preloading and fatigue cycles on bolted joints.


  • Definition of the measurement strategy to achieve the sensitivity and accuracy requirements.
  • Distinguish separately the dynamic and aerodynamic effects.
  • Durability in marine environment.


  • Design of the monitoring strategy.
  • Installation of sensors and equipment for structural load measurement
  • Interpretation and analysis of structural data. Sail aerodynamics and dynamic forces.
  • Performance metrics
  • Bolted joints fatigue analyses
  • Load analysis according to external conditions (wind and vessel movements)
