  • Stress Analysis & FEA

    Specialist stress analysis, finite element analysis (FEA), seismic and dynamic assessments to verify and optimise mechanical, piping and structural designs, helping customers demonstrate structural integrity, improve reliability and reduce engineering risk.

  • Digital design & engineering

    Digital engineering capabilities including 3D modelling, virtual reality and rapid prototyping, enabling customers to evaluate concepts, identify potential design challenges earlier and make informed engineering decisions before manufacture or installation.

Engineering support across the project lifecycle

Actemium Design UK supports projects from requirements capture, feasibility and concept design through to detailed engineering, substantiation, manufacture, testing, installation and commissioning, as well as plant life extension and upgrades.

Experienced project management and coordinated engineering disciplines provide continuity throughout delivery, helping customers manage technical interfaces, maintain quality and make informed decisions across the asset lifecycle.

40 years of engineering track record

Actemium Design UK began as North West Projects in 1987, initially specialising in control, electrical and instrumentation (CE&I) engineering for the nuclear sector.

The business subsequently expanded its capabilities to support multidisciplinary engineering projects across nuclear decommissioning, defence and other demanding environments.

North West Projects joined VINCI Energies in 2017 and became Actemium Design UK in 2021.
