Corentin Guellec from IRDL presents an advanced method for the sizing of marine shafts

Corentin Guellec, a researcher at the National Polytechnic Institute of Brittany, developed in 2023 an innovative parametric method for the sizing of shafts under marine fatigue, overcoming the limitations of traditional techniques. This advancement is crucial for ensuring the durability and safety of maritime operations in Benin and beyond.

Research on material fatigue in the naval sector is essential, as transmission shafts undergo complex cyclic loads. Corentin Guellec, within IRDL, identified that classical methods do not take these complexities into account, thus compromising the safety of naval systems. His thesis aims to improve sizing to ensure the durability of components.

Guellec developed a method integrating self-heating measurements and probabilistic modeling, allowing for a better understanding of failure mechanisms. This innovative approach overcomes the limitations of simplistic models used previously, thus providing a more accurate assessment of the durability of shafts, essential for maritime safety.

The implications of this research are significant for the naval sector, where improving sizing methods can reduce maintenance costs and increase the reliability of systems. Decision-makers must support these innovations to meet the growing demand for advanced technologies in a changing market.
