Five services built on one method: model the system, compare it with how it actually runs, and test the fix before it is built.
Discuss your system
Steady-state models of liquid networks in AFT Fathom, calibrated to field pressure, flow and temperature readings and used to plan changes.
Flow modeling services
Pump trip, pump start, valve closure and shutdown transients in AFT Impulse, with mitigation sized only where the results need it.
Surge analysis services
PSAP-led assessments of pumps and the systems they serve, covering operating points, energy and life-cycle cost.
Pump system services
Compressible-flow and gas transient models for fuel-gas and process-gas systems, in AFT Arrow and AFT xStream.
Gas flow services
Duct flow models covering fan and system curves, filter and damper effects, and variable-speed fan operation.
Airflow services
Most systems do not arrive labeled. A pressure problem can turn out to be a pump selection issue, and a pump problem can turn out to be a transient. Describe what the system is doing and the right scope can be worked out from there, sometimes combining two services in one model.
The same five stages apply whether the job is a single pump assessment or a full network model.
You outline the system, the symptom or the change being planned.
A written proposal sets out the scenarios, data needed and deliverables.
The system is built and, where field data exists, calibrated.
Results are walked through with your engineers before anything is final.
Findings, recommendations and the model itself are handed over.
