What BMTI - Alcen Group does
ALSEAMAR is a French underwater technology company operating as a subsidiary of the diversified ALCEN Group. Founded in 1986, the company has accumulated nearly 40 years of specialized expertise in designing, manufacturing, operating, and maintaining underwater solutions. It operates three facilities in southern France: an R&D/acoustics and marine surveys site in Rousset, a subsea buoyancy manufacturing facility in Six-Fours-Nord, and a radiocommunications and life-extension services site in Six-Fours-Sud.
The company's core technology platform is the SEAEXPLORER family of autonomous underwater gliders, available in standard ocean-science variants and a 1000m depth-rated variant (SEAEXPLORER 1000M) for naval defense applications. These gliders are complemented by subsea buoyancy modules (marketed under the DNV-certified BMTI sub-brand), underwater acoustic systems, radiocommunication systems, special-forces manned solutions, and in-situ underwater survey services. ALSEAMAR organizes its offering across three verticals: Ocean Science (research institutions like CNRS and Ifremer), Offshore Industries (subsea inspection, energy infrastructure), and Naval Defense (French Navy, NATO).
The business model combines hardware sales (gliders, buoyancy, acoustic, and radio systems) with professional services (surveys, after-sales, maintenance, and life-extension). Distribution is exclusively direct-to-enterprise via government procurement, defense tendering, and research-program funding channels — notably France 2030. Customers are concentrated among a small set of European government and quasi-government entities; pricing is quote-based and not publicly disclosed.

BMTI - Alcen Group product offering
Product offeringCore offering
ALSEAMAR designs, manufactures, operates, and maintains high-performance underwater technology solutions, including the proprietary SEAEXPLORER autonomous underwater glider platform (available in ocean-science and 1000m depth-rated naval-defense variants), subsea buoyancy modules and equipment (under the DNV-certified BMTI brand), underwater acoustic detection systems, and maritime radiocommunication systems. The company serves scientific research, offshore energy, and naval defense markets with integrated lifecycle support spanning manufacturing, deployment, in-situ surveys, after-sales services, and maintenance.
Product overview
ALSEAMAR (part of ALCEN Group) operates as an underwater technology company with a multi-product portfolio organized across three sectors: Ocean Science, Offshore Industries, and Naval Defense. The core product line centers on SEAEXPLORER autonomous underwater gliders, available in standard (ocean science) and 1000m depth-rated (naval defense) variants, which serve as the primary platform for oceanographic research and naval surveillance missions. Supporting the glider platform, the company offers Subsea Buoyancy Solutions (buoyancy modules and equipment), Underwater Acoustic Solutions, and Radiocommunication Systems for naval applications. The service portfolio includes In-Situ Underwater Surveys, After-Sales Services, and Maintenance Services. The BMTI sub-brand encompasses underwater technology solutions including buoyancy products that have received DNV certification. Special Forces Manned Solutions round out the naval defense offerings. The portfolio functions as an integrated ecosystem where gliders serve as data collection platforms complemented by specialized subsystems and comprehensive support services.
