Features of this service include;


  • Competent team of experienced engineers, all highly respected in the Aberdeen marketplace
  • Extensive track record of successful module designs
  • Responsive provision of quotations against minimal information
  • Adept at all major design codes and criteria(AISC, BS5950,Eurocode, DNV2.7-1, etc)

  • Fabricators are often asked to quote on minimal information
  • Module fabricators often work of tight margins and equally tight schedules
  • To meet schedules, fabricators are often required to order materials in advance of AFC design
  • Fabricators' in-house teams often possess the project management and draughting facilities and only require the engineering input
  • Late changes to accommodate client's requests need to be efficiently responded to and tracked
  • Design documentation needs to be sufficiently comprehensive for submission to the client and any verifying bodies in advance of delivery, which is often tied to payment.
