Rotork is pleased to announce that its newly established, in-house hydrostatic testing facility in Singapore is already making a significant contribution in terms of securing new contracts.
One of the first orders is from Singapore-based marine, oil and gas consultancy Praj Marine (PMC) for a project in Africa.
Rotork’s ability to provide third-party-witnessed hydrostatic testing, combined with the supply of specialised failsafe actuation solutions with short lead-times, have enabled PMC to secure new contracts for onshore wellhead and gas projects.
Specialised actuation is required because there is no power source available for valve control on the wellhead production flow line, water injection and disposal installations.
Rotork’s successful and innovative solution comprises GH and RH hydraulic spring-return actuators operated by Pressure Safe self-contained, manually operated hydraulic power packs.
A hydraulic hand pump on the compact Pressure Safe power pack is used to energise the actuator and compress the failsafe spring, holding the valve in the desired open or closed position until a failsafe signal is received, which triggers the spring to immediately drive the valve into the safe position.
Failsafe operation of Pressure Safe units can be triggered by electrical signals, high or low pressure pilots or fire sensors, enabling the reliable fulfilment of many emergency shutdown (ESD) and pressure related protection duties in the oil, gas, petrochemical and pipeline industries.
The order included mounting the actuators on 75mm (3in) and 150mm (6in) Class 1500 flanged ball valves.
