The space and workshop layouts lend themselves to high volume off-site fabrications complete with large multiple lay down areas making the facilities ideally suited to all project sizes. Find out more here:



Steelwork and Skid Unit Manufacture


From the submission of initial P&IDs and project specification, we will develop the plant layout and complete the detailed package engineering activities, including the mechanical design of piping and structures and the production of associated detailed fabrication drawings. All fabricated steelwork comes with required CE marking.

In-house electrical and instrumentation capability that enables skid units to be pre-wired, inspected and pre-commissioned prior to dispatch with fully accredited quality assurance processes.

Weld procedures are qualified to:

  • ASME
  • BS EN 15641/1
  • EN1090 Level 3
  • Nuclear Approval
