Design and manufacture of underwater watertight mechanical systems :

- Junction boxes
- Watertight connectors
- Fitted watertight cables (neoprene and polyethylene) 
- Towed linear antenna
- Maintenance and repair of towed linear antenna
- Mechanical load bearing : lifting magnet cable, load bearing on kevlar cables

- A design office guarantees the usage of high resistance steel materials, stainless steels, nickel based super-allows, to solve the problems arising from corrosion and electrolysis in a marine environment.

- A process planning and industrialisation department ensures and guarantees the manufacturing processes and adapts the means of production to manufacture in bulk or in smalll quantities.
