ALSEAMAR uses innovative surface drones and subsea gliders for independent observation of the marine environment.

These turnkey services are used to collect and analyze data for a wide range of missions: scientific research, oceanography, marine environment protection, water quality monitoring, recording of ambient noise, intervention for hydrocarbon leaks, detection of natural gas or oil leaks, baseline studies and metocean operations for oil operators.

The SeaExplorer subsea glider is a detection platform perfectly suited to these operations. A high-endurance, autonomous subsea drone, it was designed to collect data over large areas (thousands of kilometres), over long periods (months) and at great depths (1,000 m) thanks to the integration of a wide range of specific sensors.

Controlled from land, propelled by variations in buoyancy, the vehicle glides silently along the water column collecting physical, chemical, biological and/or acoustic data, depending on the mission assigned.

The added value of the SeaExplorer lies in the low operation cost compared to the vessels or other means traditionally mobilized for the same type of mission.

For applications that call for class 1 shop-fabricated stainless steel glove boxes, ALSYMEX manufactures tailored equipment incorporating all of the constraints of nuclear sites relating to the handling, transfer, transformation of radioactive material in a containment, or under a controlled neutral gas atmosphere.

With rich knowledge and expertise, ALSYMEX takes into account ventilation classes (renewal rate, dynamic containment), static containment classes (leak rate) and other specifics of the application (e.g. materials in fluid, gas or solid form), especially in glove box applications calling for mechanical processes, fluids or gases imposing specific operating constraints (T°, P, PH, H₂, O₂).

ALSYMEX designs and manufactures a line of high-performance heat exchangers consisting of superimposed pre-machined plates providing channel geometries dedicated to each application. Assembly of these individual plates calls for metallic bonds produced by a diffusion welding technique assisted by Hot Isostatic Pressing (HIP).

This technology, which involves high pressures and temperatures on the parts to be assembled, allows for welding at the heart of the material, not just on the surface. It enables the plates to be welded consistently with no added material, an operation that is impossible using more traditional techniques.

ALSYMEX has developed a system for characterizing and analyzing materials and/or nuclear fuels, by cutting, compression, traction and drilling.

ALSYMEX designs and manufactures electromechanical or electrohydraulic presses intended for the production of nuclear fuels of different sizes and geometries, for laboratory applications, in glove boxes or shielded cells.
