Rotork flow control products have been selected for applications throughout the giant Queensland coal seam gas-to-Liquefied Natural Gas (LNG) projects in Australia. To date, Rotork’s international sales network has received orders for more than 5000 valve actuators, including electric, electro-hydraulic, pneumatic and gas-over-oil technologies.
The three projects – Queensland Curtis LNG, Santos GLNG and Australia Pacific LNG – are developing coal seam gas in Queensland’s Surat and Bowen Basins. HART-enabled Rotork CVA modulating electric actuators have been ordered for the upstream mainland wellheads to provide process valve control at eventually 2000 widely distributed sites. In addition to the natural gas, CVA actuators will also control the flow on the extraction process for coal seam water.
Nearly 1000 Rotork Skilmatic SI and EH range electro-hydraulic actuators have been ordered for control valves, shutdown valves, wellhead skids and metering skids. IQ actuators for various isolating valve automation duties have also been ordered. The balance of Rotork orders involves fluid power actuators for the pipeline and the LNG plants on Curtis Island. The majority of these are CP and GP range pneumatic actuators operating butterfly valves on LNG production lines. The remainder are GO range gas-over-oil actuators, most of which are for the large mainline pipeline shutdown valves.
