What’s new in Atmos Pipe
Atmos Pipe product expert Dave Bisby started the technical presentation on the Thursday with a breakdown of the latest improvements to Atmos Pipe, which include:
- New autotuning features
- Rupture module in compliance to CFR195.417 (“Notification of potential rupture”)
- Atmos Data Manager acting as an open platform communications unified architecture (OPC UA) structure
- The additional feature of Kappa 3 to detect smaller leaks and thefts
Figure 1: An example of how the Kappa 3 feature facilitates multiple leak and theft alarms. In this case, Kappa 3’s threshold of 2.2m3/h alarmed on multiple theft events, equivalent to 1.4% of flow
Figure 2: Kappa 3 alarming on a 1 m3/h theft event, equivalent to 0.2% of flow
Since Atmos Pipe was introduced as the first statistical corrected volume balance system in 1995, we’ve continued to innovate our leak detection algorithms so that we constantly develop solutions in line with the market’s needs.

Development update for the Atmos SIM hydraulic simulation software
Atmos SIM Product Manager Glen Tyson and Software Development Manager Dave Lobban co-presented many new features of Atmos SIM.
With its simplified logic, there is now reduced time from starting a pipeline model to generating accurate results, troubleshooting is simpler on pipelines in steady state and Atmos SIM is more robust and able to solve an even greater multitude of problems.

Pipeline leak detection for multiphase pipelines
Presenting on three case studies, including two multiphase pipelines with separators, an offshore multiphase pipeline and an onshore multiphase pipeline, R&D Director Andy Hoffman was able to conclude from his research that the key to multiphase pipeline leak detection is hardware solutions. With the latest development in leak detection hardware, it is feasible to detect leaks as small as ¼ in on multiphase pipelines.

Training simulators for operator training
Technical Manager Phil Edwards discussed how the trainer module in Atmos SIM can be used to provide controllers with a safe learning environment to experience pipeline behaviors when expected and unexpected events occur. It allows both new and experienced controllers to learn about their pipelines under many different operating scenarios without having to wait for a real-life event to occur.

Maintaining a leak detection system for optimal performance
While discussing the factors that can impact a leak detection system’s performance, Principal Engineer Joe Kelly made the following summaries:
- People are key to effective leak detection, with ownership and usage, the application of corrective action through timely change control and regular interaction being important considerations
- System monitoring and maintenance of a leak detection system should involve regular interaction with systems, regular reporting on performance and frequent updates
- Ownership of a leak detection system depends on regular interaction with Atmos, timely responses to issues or questions and ownership or efficient management of the change process

Progress and challenges in pipeline theft detection
Sales and Senior Research Engineer Harry Smith discussed the ongoing problem of global pipeline theft which spans multiple regions and includes a variety of techniques.
He discussed two main theft techniques, the first being the “try and remain hidden” approach which is typically more discreet and involves the slow opening and closing of valves to steal product slowly over longer time periods, typically seen in the UK and mainland Europe.
Commonly seen in Latin America and Africa is the “slash and grab approach”, which Harry discussed in relation to angle grinding pipelines, poor installations and larger diameter taps.
While pipeline theft continues to be a global problem and thieves’ techniques are continually evolving, Harry shed light on some of the thefts we’ve detected across the world. For the total amount of thefts detected per region, see Figure 7.
Figure 7: Atmos results in pipeline theft detection and location. This data has been collated by Atmos International based on theft reporting via in-house systems and customer reports. Data correct as of June 8, 2023.
*Atmos International helped dramatically reduce the theft problem in Indonesia, reducing the number of tapping points from over 700 to zero.

How to replace CPM pipeline leak detection systems effectively
Sharing lessons learned from a real life computational pipeline monitoring (CPM) replacement project for a US pipeline company, Principal Engineer Kirsty McNeil discussed what made the project successful, such as:
- Involving stakeholders and selecting the right partners can determine if a CPM replacement is done in a timely manner
- Local and experienced teams are needed to deliver on time
- Long term goals should be considered during the different phases of the project
- Design of the CPM should consider all potential changes in the future
- System upgrades and continuous improvement should be included during the project to use latest technologies

Benefits of accurate batch tracking for crude and multi-product pipelines
Senior Principal Engineer Derek Cousins discussed batch tracking in this presentation and how Atmos Batch can provide up to the minute batch volume and accurate location of products in the pipeline in real-time.
He concluded by presenting the following benefits that can be achieved with accurate batch tracking:
- Automatic interface detection
- Position based on totalizers, ETAs on current flow
- Interface tracking, interface growth estimates
