Sail propulsion

context

Driven by new standards limiting polluting emissions, maritime transport is beginning its energy transition. It is a real engineering challenge, which is based both on hardware innovations (with the development of wind thrusters or carbon capture systems at the top of the line), but also on software innovations, to optimize the design and energy efficiency of ships. Wind propulsion, known for centuries, is being revisited and adapted to meet demanding operational and performance constraints. The effectiveness of these systems depends greatly on their settings, which must be continuously adapted to wind and navigation conditions and to the particularities of the vessels equipped.

approach

OSE has developed an innovative solution allowing the real-time control of wings in order to maximize their useful thrust on the ship, while respecting operational constraints related to the mass and inertia of the wings and their associated systems, to the effects generated by these thrusters on the ship's progress (flight, drift) and to the safety of the ship. The solution is based on a hybrid approach, combining AI, mechanical and aerodynamic calculations, and command control algorithms:

Real-time wind prediction

A module for predicting the direction and speed of the wind in the short term, based on embedded measurements (anemometer or lidar) and on an AI model trained from historical data.

Digital twin of wings and ship

A dynamic simulation to estimate the thrust produced according to wind settings and conditions, while integrating aerodynamic interactions and the influence of ship movement.

Predictive control command

Algorithms automatically optimize wing settings to maximize their thrust, by anticipating wind variations and taking into account the mass and inertia of the systems.

innovation

The development of intelligent control systems for wind propulsion is a major advance for the maritime energy transition. By automating adjustments and integrating predictive models, OSE improves performance while ensuring vessel safety.
