CAS & FATIGUE
OAS 7.5 integrates operator alertness monitoring with Hexagon’ s market-leading Collision Avoidance System( CAS 10)
He continued:“ So we’ ve been able to verify that alarms are going off on our haul roads past parked up equipment as they’ re coming out of their park ups. We’ ve been able to verify a number of alarms are as per our operating procedures. And we’ ve also been able to then tune our CAS alarms. Really, it’ s a pursuit of contextual information. If we have an incident and that equipment has got OAS fitted to it anyway, by the time the supervisor comes back to the office, which might be 20 minutes, we can have that OAS footage downloaded, ready for that supervisor to replay and understand what happened.”
For more information on CAS and OAS integration and the wider significance, IM spoke to Hexagon Principal Advisor, Josh Savit and Adrian Heieis, Global Product Manager. Savit states:“ The great thing about the OAS and CAS integration is that it was done at the server level on the technical side, so it does not add any more hardware to the mix and this actually ensures that it retains a lot of flexibility and scalability.”
He said the integration brings CAS out of a data specific world into a more contextualised world that adds a new dimension not just to safety, but to operator engagement.“ What we are hoping for is to really take CAS out of the vehicle, which will make it viable in ways that it has never been before, and we have been working with our partner Whitehaven Coal in Australia on that.”
Savit said integration will allow mines to transcend the former approach of one system just alongside the other and instead use one encompassing operator alertness system- for collision avoidance, fatigue monitoring and overall driver methodology, such as monitoring of overspeeding and some other GNSS related components.
Heieis then talked in some detail about the upsides of the technology.“ We’ re in a fortunate position at Hexagon where we have so many leading solutions that the hardest part of my job is figuring out the best way to integrate them, because
there’ s countless possibilities. Broadly I would say our integration strategy involves three categories. First there is an onboard hardware integration which is focused on reducing clutter and complexity and reducing maintenance requirements. This saves space but also improves the overall operator experience. Then there is a functional integration, where our solutions like CAS and OAS work together onboard in real time. And then there’ s a third type of integration, which is insights and data integration. How can you pull the data from the different systems to gain new context and understand your operation both from a productivity and a safety perspective?”
Heieis said it is already well advanced in the first part- OAS and Hexagon’ s fleet management system OP Pro are being integrated via what it calls the‘ Single Core’ initiative, which will be commercially available in 2026 with customer pilots planned for early in the year. With this advancement, users will only need one computer between the two systems. This also means much simpler installation and reduced cost on both sides. These upfront hardware integrations also enable later realtime onboard functional integrations.
On the offboard side, and data integration, OAS and OP Pro are already integrated for things like operator login and equipment activity tracking, and nowOAS and CAS are also working together. Heieis:“ The power of the integration today is that it’ s providing context that we’ ve never had before. In the past we have tried to make sense of the data coming from CAS using heat maps and trends. You pinpoint which haul roads, pits, times of day, plus which operators and crews have the most events, which remains really important to get baseline KPIs and greater understanding of the risk that you have. But having the integration with OAS where you can actually see the videos makes it so tangible and helps you understand the root causes, so you know what you have to do to actually reduce that risk over time.”
The primary use case for OAS is and always will be addressing the risk of fatigue related microsleeps and operator alertness, however, because you have the core technology of the cameras, it gives you a lot of context, whether it’ s watching and validating a fatigue event, which is done through Hexagon’ s remote monitoring centres, or understanding the root cause of a collision event from CAS, or conducting an incident investigation.“ I’ ve seen a significant shift in how mining operations manage and address safety risks on site, in part because of their ability to extract the data coming from systems like Hexagon’ s OAS and CAS, especially by actually watching an event or incident that occurred from multiple video angles.” said Heieis.
Heieis restated the fact that the integration done on the server is significant as it can be turned on and managed completely remotely.“ There’ s no downtime, there’ s no additional hardware, there’ s no lead time to get the hardware to do the installation. If you have a vehicle that has OAS and CAS, you could have the integration running tomorrow including the videos of any events.”
The OAS-CAS integration has been commercially available since July when the successful trial at Whitehaven Tarrawonga ended. Since then, five more customers have upgraded to OAS 7.5 and two of those are now running the OAS-CAS integration. The OAS-FMS hardware integration is 99 % complete and in the stabilisation phase, with Hexagon identifying any bugs or issues ahead of pilots lined up in South America for early 2026 and commercial availability within 2026.
Another aspect of the integration is the use of AI to analyse the data, which is part of a wider safety insights roadmap within Hexagon, building on the integration platform developed out of OAS through CAS and later the next version of Hexagon’ s Level 9 collision avoidance technology, VIS 2.0, also set for release in 2026.
On the AI piece, Savit commented:“ That world is ever growing, with our smart centres at the heart of these efforts- there we are starting to coalesce data and move it away from being purely linear to more bow tie and other types of analytical processing.
We have gone from machine learning to AI but now it’ s AI with machine learning. At Hexagon we are doing more things with AI, neural networks and data algorithms to further develop our insights platform which will be a major focus in 2026 and beyond.” Today, Hexagon has smart centres in Latin America and APAC that are handling this global safety and fleet data analysis. Then it has its remote monitoring centres which bring OAS and now CAS insights – these are in Peru, Mexico, the USA and Indonesia plus another one will open in South Africa in 2026.
Ultimately, as these integrated safety systems evolve, there is also interest from mining customers in having them embedded in their own integrated remote operations centres( IROCs) and Hexagon is already offering an onsite service, where its team will go and teach the customer team how to monitor and manage the systems in that space. At larger mines this may also include Hexagon personnel being permanently based with the customer – just as AHS controllers are today.
Hexagon is also looking to how it can move more of its system functionality into the underground space as mining
