Products
Digital Engineering
Simulation, digital twins and engineering data management applied to industrial assets. It supports the group's core engineering work rather than being sold as standalone software, and it is increasingly what clients expect a modern nuclear design package to include.
assystem.com
Transport Infrastructure
Design and construction supervision for rail, metro and road projects, particularly in France and the Middle East. Assignments run from early feasibility studies through construction oversight to commissioning, which keeps teams on a single programme for years.
assystem.com
Energy Transition Engineering
Engineering for transmission networks, renewable generation and hydrogen infrastructure. It applies the same programme discipline the nuclear work requires to newer forms of generation and grid capacity.
assystem.com
Project Management Assistance
Owner-side support on large capital programmes, covering schedule, cost, interface management and contractor oversight. The firm acts on behalf of the client rather than as a contractor, which keeps it independent of the parties it supervises.
assystem.com
Nuclear Engineering
Design, safety case preparation and project management for new reactors, plant life extension and decommissioning programmes. It is the group's defining specialism, and the long qualification cycles in the sector make experienced nuclear engineers a scarce and defensible asset.
