Rotork Fluid Systems has completed the delivery of forty-four specially customised hydraulic valve actuators for sub-sea installations in ten weeks from receipt of order. Ordered for the Turkmenistan Block 1 Gas Development Project in the South Caspian Sea, the actuators will operate ANSI Class 150 ball valves in sizes 6in and larger. The quarter-turn actuators utilise the Rotork RH rack and pinion centre body design in sizes 120 and 240. All the actuators are equipped with pressure compensation systems and ROV (remotely operated underwater vehicle) receptacles for the rotary tool operation of mechanical override systems. The Turkmenistan Block 1 Gas Development Project is being undertaken by a subsidiary of the Malaysian oil and gas company Petronas and will comprise two delivery platforms, one riser platform, an onshore gas terminal and associated pipelines.
