Rotork actuators selected for FPSO

Tanks and Terminals,

Electric and fluid power actuators from Rotork have been installed on a new floating production storage and offloading (FPSO) vessel in Brazil.

The customer, Metroval, specified Rotork intelligent IQ3 multi-turn electric actuators, as well as CP and GP pneumatic actuators, to control plug and butterfly valves on the 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 boe/d.

The actuators will be operated by end user Modec to control the flow of oil and gas from the FPSO to the metering system, with the accuracy of the IQ3, CP and GP actuators a key factor in the customer’s decision to purchase Rotork’s products. Rotork Site Services assisted with installation of the actuators on site by providing valve adaptation, mounting the actuators on to the valves and commissioning.

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 4500 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 explosion-proof to ATEX 2014/34/EU standard.
