Our engineering services have a strong focus on energy and resources, and were presented the German Award For Natural Resources Efficiency 2016 (Deutscher Rohstoff Effizienzpreis).
Analysis & Optimisation
We have experiences working with the following international codes:
  • ASME
  • DIN EN
  • BS
  • AD/TRD
  • GB/T16507
  • IBR
  • IPS-G-ME-180
  • GOST
  • METI
  • JIS
  • Australian Standards
  • Germanischer Lloyd
  • Det Norske Veritas
  • ABS

Our services include expert reports on plant analysis and optimisation, plant upgrades and revamps, fouling, flow optimisation, strength analysis, as well as detail engineering. We cover standard designs for oil and gas-fired boilers to very specialised tasks, such as creating designs for chemical heaters and solar thermal energy plants, and collaborate with plant owners, project developers, engineering companies, EPCs, and OEMs.

Due to its extensive international network, ERK has expertise with many codes and standards worldwide and understands the differences between them and the cost implications involved. Our boilers comply with all relevant codes and standards.
