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.

COVID-19 – Operations Update

Dear Customer,

As the impact of Coronavirus (COVID-19) continues across the globe, it is our aim to assure and support our customers. This is why I am writing to you today. I wish to assure you of our contingency plan to ensure our services remains operational and that there will be as little disruption to projects as possible.

Our top priorities are the welfare of our employees, as well as maintaining the high level of project performance for our much valued customers.

For the past decade, our working practices and IT operations have been designed with flexible and remote working in mind. This means that, in the event any of our offices need to be closed for a period of time, many of our staff will be able to continue to work from home on a full-time basis for the required period.

We are confident there will be minimum disruption to any service we provide and are working closely as a team to maintain visibility of any potential impacts.

Kind regards,

Glyn Addicott
Group Operations Director
