Fast track performance achieves ten week delivery for sub-sea valve actuators
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 6 inches and larger. The quarter-turn actuators utilise the rugged 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 fast-track order is the latest in Rotork’s extensive reference list of sub-sea valve actuation projects, stretching back to 1992. The company has successfully completed hyperbaric testing of its sub-sea products at simulated depths of 2500 metres.
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.
