Rotork wins valve control contract in project to boost Malaysia''s oil and gas industry

With the completion of Phase 1A of the project, 274 explosionproof IQ3 actuators fitted with Rotork Gears IB bevel gearboxes have been installed to operate gate valves on flow control applications throughout new import jetty and storage tank facilities. The actuators are monitored and controlled by eight Pakscan P3 120-channel hot/standby master stations, situated on-site in three cabinets and linked to a centralised Yokogawa SCADA system.

The well-proven and rugged Rotork IQ3 actuator incorporates advanced data-logging, diagnostic and communication features, providing a high level of functionality and asset management abilities. Innovations have been introduced to enable the operator to access more data in the field and, via the Pakscan P3 network, in the control room. Pakscan P3 delivers secure field communications with inbuilt network redundancy and is specifically designed for valve actuation activities in the spacious environments associated with tank farm installations. Each network is capable of monitoring and controlling up to 240 field units without repeaters on a single two-wire highway with a 20 kilometre maximum length.

Rotork''s success with this project has been assisted by customers'' previous experiences with Rotork products and the support of its international sales and service organisation. More than 300 IQ actuators with Pakscan have been operating reliably for nearly five years at DIALOG''s Tanjung Langsat Tank Farm, with a local source for service engineers and after sales support provided by Rotork Malaysia. For the Pengerang Terminal project, the order for actuators was placed with a valvemaker in China and supplied by Rotork Shanghai, whilst the Pakscan order was placed with Rotork Malaysia.
