Joint Laboratory of Marine Technology : Naval Group, Sirehna et Centrale Nantes

Naval Group, Sirehna and Centrale Nantes signed an agreement to continue their co-operation within their joint research laboratory, the Joint Laboratory of Marine Technology (JLMT).

To give Naval Group's ships true operational superiority on the seas, the Joint Laboratory of Marine Technology (JLMT) is boosting technological development in three key areas in military shipbuilding: additive manufacturing, naval hydrodynamics and multi-physics numerical simulation.

This joint laboratory has already delivered a key industrial application for Naval Group: in June 2018, the world’s first hollow propeller blade demonstrator was printed on a 1/3 scale via additive manufacturing. Implementing the Wire Arc for Additive Manufacturing process allows for the printing of large parts and paves the way for the production of hollow propeller blades with more complex geometry.

The JLMT has forged strong links between Naval Group, Sirehna and Centrale Nantes.

Established in 2016, the JLMT is a joint industry/research laboratory whose objective is to pool the academic and industrial expertise of Centrale Nantes, the University of Nantes and Naval Group in order to inject innovation into Naval Group's industrial applications in the field of military shipbuilding.

The first agreement signed covered the period 2016 to 2020. This agreement has now been extended until 2023.
Today’s partnership between Naval Group and Centrale Nantes focuses, in particular, on materials, the human factor, augmented reality and ecodesign.
