Hydraulic-operated master valve control in emergency situations
Traditionally a fusible cap must be installed on the pneumatic actuator rod to prevent undesirable closure should the emergency shutdown (ESD) system be activated while wire or cable is across the master valve. In an emergency, the master valve cannot be closed unless the fusible cap is removed or, in the worst cases, the heat of a fire melts the low-melting-point alloy.
The hydraulic hold-open tool of Peak Family™ flow control and well intervention tools provides a hydraulic-operated alternative to the conventional fusible cap, enhancing wellsite safety in wells with pneumatic actuators operating the master valve. It can be attached to the actuator temporarily for the duration of the well intervention.
