By contrast, if gas pressure is too high, it can create leaks in the system that have to be systematically tracked down and fixed. In addition to the obvious safety concerns, natural gas is a greenhouse gas and, when released to the atmosphere without first being combusted, has a 25 times more potent global warming potential than CO2. So it is very important for the environment to keep as much gas inside the pipe network as possible.
Abriox has introduced a radically new way to collect and manage gas distribution pressure data. OSPREY is a fully automatic system comprising:
Permanently deployed, intelligent monitoring units incorporating GPS for identification of location and precise time synchronization of data
Remote communication via GPRS for reports, alarms and data download
Integration of the data into a software platform (PressureTrac®) that can be interfaced with the model used by the gas utilities and with their in-house business systems
OSPREY completely eliminates manual data collection of pressure data, saving time and money. It also massively improves the quality of pressure data - leading to gas production savings, improved gas network efficiency and a reduction in greenhouse gas emissions through leakage.
OSPREY Pressure monitors can be used for:
Network validation - the annual process whereby pressure data, recorded at various points, confirms the accuracy of a sophisticated computer model of the gas network. This model is the basis for network planning
Investigations of poor pressure – responding to customer calls, monitoring the variations in pressure to the household or industrial premises and assisting in the timely resolution of the complaint
System maintenance – ensuring that pressures are maintained at the correct level while work on the gas network is carried out
Calculation of average system pressures over long term periods – OSPREY has a minimum 5 year battery life and holds 10 years of data at standard logging intervals
Monitoring third party feed-ins to the gas network, such as from bio-methane or fracking
Monitoring the intermediate pressure input to district governors (with alternative sensor pressure range 0-10 bar)
The ability to view system pressures dynamically has immense potential for improving network management, responding to network incidents and feeding directly into average system pressure calculations.
Some of the immediate benefits OSPREY provides include:
