Severn Glocon Group has been contracted to supply severe service control valves to the Gorgon Project gas processing plant on Barrow Island, approximately 130km off the northwest coast of Australia.
The initial order was awarded to the Group in May 2010 and the first of the bespoke valves began shipping in mid-2011, in line with the modular construction programme. Most of the valves have been manufactured and are either shipped or awaiting shipping release.
Designed and manufactured by Severn Glocon, the valves are for use in many severe applications such as compressor anti-surge, blowdown, gas to flare, low shear and flow control. Some of the valves are manufactured in solid Inconel alloy. The sheer value of this raw material makes them extremely complex to manufacture.
Due to the severity of the applications and the requirement for extraordinary performance, the manufacturing tolerances and attention to detail have been strictly controlled.
This is reported to be one of the largest severe service control valve orders ever issued, both in terms of value and the number of units required.
The Gorgon Project is operated by an Australian subsidiary of Chevron and is a joint venture of the Australian subsidiaries of Chevron (approximately 47%), ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%) and Chubu Electric Power (0.417%).
It includes the construction of a 15MTPA-LNG plant on Barrow Island and a domestic gas plant with the capacity to provide 300 terajoules per day to supply gas to Western Australia.
