BP Exploration has specified new electro-hydraulic actuators manufactured by Rotork for a critical valve upgrade on the BP Unity platform, a vital unmanned facility that receives the oil from five fields in the North Sea. Eleven Rotork EH Range actuators will perform ESD (Emergency Shut Down) duties on high pressure (Class 1500) riser ball valves, replacing traditional hydraulic actuators and associated bulky compressor plants. Rotork’s dedicated data logging and diagnostic capabilities enable valve and actuator condition to be remotely monitored and logged – in this case at the BP Unity platform onshore control centre – minimising the risk of unexpected problems and helping to maintain the platform’s very high availability commitment.
