Emergency Shut Down Control Panel is designed to generate signal to pneumatically control the
hydraulic flowhead valve or any other single-action, fail-safe
hydraulically activated valve. ESD system controls the hydraulic
safety valve on the test tree and on the wellhead wing valve and
allows manual or remote closure in response to any equipment
failure upstream of the choke manifold such as pipe leaks,
equipment malfuntion, fire or any emergency that may occur during
the operation
ESD system consists of ESD control panel with air-driven hydraulic
pump, hydraulic tank, air hoses, and hydraulic hoses, ESD remote
stations,High- and low-pressure pilots, and the storage reels for
hoses.
