Surge Analysis & Flow Assurance Experts

Hydraulic Analysis Group Limited is the acknowledged worldwide leading engineering consultancy for undertaking pipeline single phase flow assurance and surge analysis (waterhammer) studies. As an independent consultancy, we are able to offer our clients unbiased advice on all aspects of pipeline hydraulic design, pressure transients and equipment selection. We also specialise in real-time pipeline management installations and automated hydraulic leak detection systems.

With 45 years of experience and over 10,000 studies completed in over 50 countries, we are trusted by the world’s major water, oil, gas, energy and petrochemical companies to conduct detailed pipeline flow studies. Using pipeline simulators, developed within the group, we model and optimise pipelines and pipe networks at the design stage and we also investigate operating problems and proposed changes in operating philosophy on existing systems to verify pipeline and control system design.

We can directly evidence burst reductions of 90% on assets which we have optimised following site pressure and flow logging.

The main advantages of our software when compared to other commercially available products is the use of a continually varying pipeline wavespeed together with the ability to model complex control systems. When combined with our ability to model accurate temperature variations along the system, this results in truly accurate computer simulation of pipelines.

We have an extensive portfolio of validation cases to demonstrate the proven accuracy of our software, including many real-time liquid and gas systems. Our software typically shows just a 1% or 2% difference between recorded values on site.

Hydraulic Analysis Limited are delighted to announce that our Yorkshire Water Rising Main Investigations with GHD and Barhale has won the 2019 CIWEM Sustainability Award.

Our commitment to understanding why rising mains are bursting through on site flow and pressure logging together with computer modelling of the asset to trial out different possible solutions has already yielded significant benefits and understanding.

This award accompanies our Institute of Water award with DCWW for similar Rising Main Investigations and Burst Reduction.
