Largest ever contract for IMI Critical Engineering: 3,600 valves being supplied to Gorgon gas project


​​​IMI Critical Engineering has secured its largest ever global contract, worth approximately €70 million, to supply 3,600 of its acclaimed ball, control and triple eccentric butterfly valves to the Gorgon gas project off the coast of Western Australia. The valves are destined for the dedicated liquefied natural gas (LNG) plant serving the Gorgon gas project, one of the largest of its kind in the world.

The proven high quality and performance of IMI Critical’s valves were key to the contract win in this environmentally sensitive location. The Gorgon gas project is located in a Class A nature reserve, home to vulnerable species such as the flatback turtle. The need to protect the environment meant the product specifications were particularly stringent, not least in relation to extremely low allowable leakage levels and long-term sealing performance.

Top entry ball valves from IMI Truflo Rona were specified for their proven ability to cope with extremes of both hot and cold (down to cryogenics temperatures below -162ºC) and to provide 100 per cent shut-off.  This level of reliability is key given that an unscheduled shutdown could cost upwards of US$10 million each day in lost revenue.

The control valves selected were specified to address applications that ranged from gas flare to antisurge and hot gas bypass. The largest of these valves were 36 inch inlet and outlet that had plugs which weighed over one ton and capable of moving full stroke in less than one second.

The triple eccentric butterfly valves from IMI Orton were chosen for their proven performance and Orton’s ability to design fully replaceable sealing elements. These will allow the valves to be serviced locally, instead of having to be shipped back to the manufacturer for repair, delivering significant savings on maintenance costs.

Enzo Stendardo of IMI Critical Engineering explained: “In a processing plant of this size, downtime cannot be countenanced because of the huge costs entailed, placing a real onus on valves to work without interruption between scheduled maintenance stops. The contract is therefore a strong endorsement of our ability to meet the needs of the global LNG sector from a product range which harnesses high-specification materials and innovative design to deliver outstanding performance in the most demanding operating conditions.”

The LNG plant will begin operating later in 2015.
