Rotork’s intelligent IQ3 multi-turn electric actuators, as well as CP and GP pneumatic actuators, have been chosen to control plug and butterfly valves on an FPSO, which will operate in the LIBRA oil fields in the Atlantic Ocean’s Santos Basin. The FPSO operating at the site is expected to produce 180,000 barrels of oil equivalent per day.
Rotork’s versatile, modular CP range of pneumatic actuators use a scotch yoke design, available in both spring-return and double-acting configurations. The actuator’s compact and efficient design is capable of producing high output torques of up to 4,500 Nm (39,800 lbf.ft) even at low pressures. Corrosion resistant cylinders are made from carbon steel and are electroless nickel-plated while the CP is suitable for use in Safety Integrity Level 3 (SIL3) applications, certified to IP 66M/67M for environmental protection and explosionproof to ATEX 2014/34/EU standard.
Rotork’s intelligent IQ3 electric actuators can be used for isolation or regulating duties of up to 60 starts per hour, with a direct torque output range from 14 Nm (10 lbf.ft) to 3,000 Nm (2,200 lbf.ft). The actuator features advanced data logger technology to record detailed information including valve torque profiles, operational starts profiles, vibration and temperature trend logs, and event logs. All data, which can be viewed on a dual-stacked advanced display, can be securely transferred to a PC for analysis using Rotork’s Insight 2 software.
