The transition coincides with the relocation of Lorient-based teams to a larger facility at the beginning of 2026, which is anticipated to triple production capacity.
Mappem Geophysics, a company specialising in marine electromagnetism and acquired by the group in September last year, will continue to operate from its site in Saint-Renan.
RTsys Group executives Jean-Luc Biache and François-Xavier de Cointet said: “This name change represents far more than a simple rebranding: it marks the realization of our collective ambition to position RTsys Group as a world-leading player in marine and underwater technologies.
“Our new organisation and enhanced industrial capacities will enable us to respond with agility and excellence to our clients’ growing needs.”
In 2025, RTsys Group secured more than €4m ($4.6m) in additional long-term financing, of which €2m came through a capital increase to support the industrial changes and reinforce investment in research and development.
