What are the exciting new features in our latest software release: Barlind?

By Bernt Eldor on 08/03/23 09:51

The high level theme for the release is how we ensure coverage of failure modes. Kairos functional modelling is now based on a process library of safety and operability units. The building blocks are based on design guidelines with Failure Mode and Effects Analysis (FMEA) and Experience (ISO14224). This has radically improved the models where the total number of failure modes has been increased by a factor 10. A topside model will now typically cover 3500 failure modes. In short: higher quality models implemented faster with little to no user involvement.

Research from Kairos presented at ESREL and SAFEPROCESS conferences

By Ivan Rott on 22/09/22 11:23

Kairos' research team and our collaboration partners have provided several important research publications this summer. Functional modelling technology (by means of Multilevel Flow Modelling) and developed tools reason about the relation between cause and consequence in complex systems. Using the data from SCADA/control systems, guidance is provided to help the operator on root causes and how to mitigate them. 


Kairos internship fellow Mohammad Bakhshandeh presented his latest study paper at the ESREL-conference in Ireland. Mohammad is currently completing his Ph.D at University of Stavanger. His research address advanced situation awareness, Human Vigilance, and Sensitivity in complex and dynamic Industrial systems. When modern industrial systems are subjected to complex operating conditions, they generate higher potentials for a wide range of abnormalities, deviations, rare events, and incessant changes. Ad-SA based on enhanced human vigilance and sensitivity is gradually becoming a critical need to ensure high-resilience of such systems and contexts. Mohammad´s publication is available here.


The ESREL 2022 (32nd European Safety and Reliability Conference) was held between 28th of August - 1st of September 2022 at Dublin, Ireland with five days of intense exchange on scientific research and industry practices on the various themes and areas, underpinning this year title: “Understanding and Managing Risk and Reliability for a Sustainable Future”.


Secondly, our research team in Denmark, in close collaboration with Danish Technical University and University of Le-Harvre, Normandie, France, opened up for new improved fault diagnostics opportunities, with Kairos functional modelling technology, used for complex and hazardous plant production systems. Current tools have a limitation, namely that the timing aspect of the propagation to consequences is not considered. The presented research proposes a method to develop a timed causal analysis that will use timing information to filter the sequence of alarms in the SCADA/control systems to help operators assess the development of alarms in case of a critical event. The publication is available online here.


The SAFEPROCESS symposium is a major international gathering of leading exerts in the academia and industry from all over the world. It aims at strengthening the contact between academia and industry to build new networks and cultivate existing relations. SAFEPROCESS is organised every three years by IFAC.

Kairos Scenario Maker is now available

By Ivan Rott on 25/08/20 09:08

To be able to run good workshops with our clients during the restrictions of Covid-19, we have developed Kairos Scenario Maker for testing process models built for Kairos - Control Room Assistant.

With our new tool, it is easy introduce different hypothetical errors to demonstrate and test how the fault propagates through the plant process. A live session with the tool will also provide better understanding of how Kairos can assist your production to safer operation and higher efficiency.


Watch video on how Kairos - Control Room Assistant works


We can also, from historic data, test how plant trips could have been avoided, as well as letting you train your operation team on plant behaviors. The tool helps demonstrate how the causal reasoning works, which is important to ensure that the artificial intelligence becomes explainable.

By using Kairos Scenario Maker User Interface, observations (sensor status) are selected for scenarios chosen to be tested, by simply assigning values outside their limits to see and understand how the AI reasoning works.




The behavior of your plant caused by these introduced "upsets" (top ranked causes and consequences), are presented in Kairos - Control Room Assistant on screen.

How human intelligence gets Kairos up and running on your plant faster

By Ivan Rott on 30/06/20 10:00

To support safe and optimal plant production Kairos - Control Room Assistant provides the control room operator with an instant status of the entire process and predicts possible causes and consequences of any system upsets in real-time.


How does the control room assistant work?

For starters, we model the goals and functions of the complex industrial system as it is designed. Together with an increasing number of clients, we have established a library of each process function based on previous models built for the industry. In these library components we have already built in the design knowledge, its objectives, and functional behaviour. This way, industry "knowhow" and valuable operational experience is kept and shared.


The Onboarding Working Process

Our onboarding process is a straight-forward 4-step process from model development to operation.

1. Model development

2. Workbench offline testing

3. Real-time implementation

4. Operation


Library for safe and effective modelling

It is easy and safe to model a new plant or system based on the plant design information, because we are using the established library blocks. The normal time to build a main process model for a medium offshore installation is now reduced to 8-12 working weeks.


Human Intelligence  - The Objective trees

Kairos Technology will establish the objective trees, which is the description of the functional behaviour of the process. The functional models are built based on mass and energy flow transformations. The functional models areincorporated with process, mechanical & control design knowledge, as well as including the industry best operational experience.


Workshops - Adapting and sharing Operational Experience

We normally propose a couple of 2-4 hour workshops with the customer to discuss the prepared objective trees. We share the knowledge from other plants and adapt the objective trees to the customers' own unique operational experiences for their specific plant objective and industry knowhow.



Validation and Familiarization

Kairos Technology builds the model and uses our Scenario Maker to simulate the process behavior of the model. Test scenarios will be agreed on and performed to see the outcome and verify the model and plant design before implementation. The Scenario Maker can also be used to train operators on process disturbances and its cause/consequences.  


Implementing Real-Time Data

When the model is verified, it will be connected to the plant and run with real-time data via standard OPC UA interface.

By this point you are ready and Kairos - Control Room Assistant is helping your operators make better decisions for the plant.

System maintenance of Kairos will be minimal as Kairos adapts to site data and parameter settings of the plant. Major plant modifications will be taken into account through the usual Management of Change process.
