Combining experience and tehnology, Alyotech Group specializes in two branches : engineering and IT

For 15 years, Alyotech has been crafting innovative solutions for the Defense, Naval and Aerospace sectors in environment and

materials modeling and simulation.

METANE is a physical modelling tool which simulates the behavior of oil and gas accidentally released in marine environment.

It takes into account gas dissolution, hydrates formation / decomposition and deals with ultra-high pressure conditions (high deep).

The software integrates an innovative high performance 3D graphic toolkit to visualize the fate of the plume in water column.

SeaMotion is a software designed by Alyotech. SeaMotion features an alternative solution to measurement campaigns.

It aims at producing multiband data (Visible, EO, EM) and allow realistic and swift multi-incident analysis for defences and national security and surveillance issue
