BATH, UK – MIR Valve has contracted Rotork to supply hydraulic actuators for Petronas’ Bokor oilfield Phase 3 redevelopment offshore Sarawak.
The 12 RH rack and pinion actuators will control subsea ball valves on a jacket flooding system. The latter is used to coordinate opening and closing of flooding and venting ballast chambers that employ seawater to support and stabilize large offshore structures.
Petronas’ project involves installation of three wellhead platforms. The actuators will be installed 70 m (229 ft) underwater, opening the valves once within 48 hours of the jacket being submerged and ensuring a fail-safe return to the closed position if there is a hydraulic supply failure in future.
Rotork says its RH actuators were specified because a hydraulic power supply is the preferred method for subsea actuation.
