Introduction
The integrated gas well pad (GWP) telecontrol system gathers
information form all field facilities including well clusters, gas
treatment station and shipment stations. The system monitors and
controls geographically distributed well sites via RTUs installed
in container houses onsite.
Scope of Automation
- low pressure flare;
- group metering station;
- flow meters, temperature and pressure sensors;
- gas treatment station;
- shipment station;
- fire and security alarm subsystem;
- container house utility subsystem.
Main Features
- monitoring of technological parameters;
- automatic control of process facilities;
- automatic shutdown of process equipment at a well cluster site
when there is a fire alarm signal coming from the fire and security
alarm subsystem;
- communication and collection of information in one system
server;
- visualization of operating procedures on the basis of
standardized screen forms;
- generation of emergency and event messages;
- storage of message history and message meanings;
- control of operating procedures from unified screen forms;
- provision of access to screen forms with differentiated access
rights and a possibility of remote access via web interface;
- displaying of messages in online and history modes;
- report generation in accordance with customer's
requirements.
Information exchange between subsystems is mainly carried out
using wireless data communication networks on the basis of radio
stations. Information from all wells is communicated to the
redundant I/O server located at the container house of the gas
treatment station, which functions as a field control center. Field
operator's workstation is also located in the container house.
Benefits
The system can be completed by modules allowing solving
different telecontrol tasks.
GWP telecontrol system can be used at different remote sites
with different types of actuating devices and sensors.
The system components provide for additional operation modes
(simulation, testing and masking) and other features, such as
unauthorized access protection and event logging to monitor
personnel actions.
The system has all necessary certificates and operation
permits.
GWP telecontrol system is delivered as a turnkey container house
solution, which ensures optimal commissioning time.
