This operation provides valuable support to the company’s fabrication and project activities.

Our professional design engineers have a reputation for developing innovative solutions particularly in the areas of seismic design of column and vessels.

Computer aided design analysis and draughting is used to ensure timely and consistently accurate results. Engineering maintains contacts with a variety of design groups in different disciplines and specialist fields to allow complete designs to be offered.

Engineering supports includes stress analysis of structures, piping systems, flange details, nozzles and pressure vessels.

Robt. Stone's design engineers routinely work to such accepted and widely used standards as BS806, ASME B31.1 and B31.3 for pipe work, API 650 and BS2654 for storage tanks, PD5500 , ASME VIII and AS1210 for pressure vessels, combined with Business Development Manager 3274 and TEMA for shell and tube heat exchangers.

Recent completed design and build projects include:

• Lihir 20MW geothermal steam field piping. - project sheet
• 20tonne Steam Separator. - project sheet
• Twin Cyclone Steam Silencer  - project sheet
• Kawerau geothermal steam field piping (project sheet to come)
