What does a GASWorkS specialist do?
A GASWorkS specialist builds and runs steady-state gas network models to analyze the performance of distribution, transmission, gathering, fuel, or plant piping systems. This role focuses on configuring solution routines within the GASWorkS software to compute critical hydraulic parameters such as pressures, flows, velocities, and gas properties across complex networks. The specialist sizes and designs system components while maintaining accurate model attributes for detailed analysis and reporting.
- The specialist creates steady-state models of gas piping systems using the map-style graphical data interface in GASWorkS. They construct the network by defining nodes, pipes, regulators, compressors, and other elements to represent the physical infrastructure accurately. This process involves importing graphic and attribute data from CAD or GIS formats such as DXF, SHP, or KML to establish the baseline geometry. The model serves as the digital twin for all subsequent hydraulic analysis and design tasks.
- They configure and execute the Newton-Nodal iterative solution routine to calculate pressure drops, flow rates, and velocities throughout the network. The specialist selects appropriate solution options to ensure the mathematical convergence of the model under various operating conditions. They analyze the resulting gas properties and identify any exceptions or violations in the solution log. This step verifies that the system operates within safe and efficient hydraulic limits.
- The specialist uses built-in tools to size pipes and model regulators or compressors based on the computed hydraulic results. They adjust component parameters to meet design criteria and optimize the network performance for specific demand scenarios. This work ensures that the selected infrastructure can handle the required gas volumes without exceeding pressure constraints. The output includes specific sizing calculations and derived values for key equipment.
- They generate spreadsheet-style reports that detail pipe characteristics, node pressures, customer connections, and solution exceptions. These reports provide stakeholders with clear, tabular data for review and decision-making. The specialist exports these results to Microsoft Excel, Access, or other database formats for further analysis. This deliverable translates complex simulation data into actionable insights for engineering teams.
- The specialist maintains model integrity by updating attributes and exchanging data with external systems. They export model schematics and tabular data to support downstream reviews or integration with other engineering tools. This workflow ensures that the gas network model remains current and aligned with as-built conditions or proposed changes. The final datasets facilitate collaboration with clients who use different software platforms for asset management.
