Roles held inside: Microsoft. Delivery and transformation roles, on contract and in permanent positions, rather than engagements delivered under the Tenhaw banner.
Industrial, energy and infrastructure organisations face the inverse of the retail problem: decisions are consequential and expensive to reverse, assets have decade-long lifecycles, and teams are distributed across continents and time zones. The binding constraints here are safety cases and OT security rather than conduct regulation. That means management of change under a functional safety regime, and the boundary between corporate IT and the control domain that the NIS Regulations, NIS2 and IEC 62443 exist to protect. Agentic value concentrates in engineering knowledge work, simulation and planning, not in operational decisioning. Tenhaw built and ran the digital teams behind Anglo American's £40bn hydrogen business case and made global delivery predictable at Yondr across the UK, US and Singapore. Tenhaw is a UK agentic AI consultancy and delivery partner: we build and run the digital teams, and we do not write safety cases.
That is the short answer for the sector. The call is where it gets specific to your organisation.
Regulation in industrial, energy and infrastructure
The constraints that decide the sequence
Not the ones that sound good in a deck. These determine which workflows can move to agents at all, and in what order.
01
Decisions are expensive and slow to reverse
A wrong call on a capital project is not undone in a sprint. The human-in-the-loop boundary sits much further toward human judgement than in consumer businesses, and agentic value has to be found in the analysis that informs decisions rather than in the decisions themselves.
02
Teams are genuinely distributed
Engineering and delivery teams spread across three continents mean asynchronous working is a necessity rather than a preference. Agentic workflows that assume a synchronous team in one time zone do not survive contact with the operating reality.
03
Specialist knowledge is scarce and concentrated
Deep domain expertise sits with a small number of highly qualified people whose time is the actual constraint on the business. Agents that amplify that scarce expertise are worth far more than agents that automate abundant work.
04
Safety and environmental accountability are absolute
Anything adjacent to operational safety carries a governance burden that back-office automation does not, because the safety case is the argument that permits the asset to operate. This is usually a reason to start elsewhere rather than a problem to solve first.
Data residency, model risk and auditability are questions about us as much as about your estate. Our security and assurance position says what we hold today and what we do not.
If a different constraint is the one actually binding you, bring it to the call.
Safety cases, OT security, and the frameworks procurement now asks about
The gating questions here are whether the system's behaviour can be argued for in a safety case, and what identity it holds when it asks to cross the boundary into the control domain.
Safety cases, ALARP and management of change
Operators of major hazard, energy and infrastructure assets: COMAH sites, offshore installations under the Safety Case Regulations, nuclear under the ONR, and anything carrying a functional safety case under IEC 61508 or 61511. The general duty under the Health and Safety at Work Act sits under all of it.
What it requires of an agent
A safety case is an argument, supported by evidence, that risks are reduced so far as is reasonably practicable. It rests on the behaviour of the system being characterised, which is a demanding bar for anything whose output is not reproducible. Any change to a safety-related system triggers management of change and reassessment, and a supplier updating a model is a change whether or not anyone in your organisation initiated it.
Where programmes fall down
The boundary gets crossed by drift, not by decision. A tool arrives as decision support, becomes the thing operators actually rely on, and no management-of-change assessment was ever triggered because nothing in the control system changed. The second pattern is a safety argument written against a fixed model that is then updated on the supplier's release schedule rather than yours.
What our method does about it
We keep agents on the analysis side of the boundary by design, and we make the boundary explicit rather than assumed, so that crossing it has to be somebody's decision. Where a workflow informs a safety-relevant judgement we require the management-of-change gate before the pilot, with pinned model versions and change control your safety function owns. Usually this is a reason to start somewhere else entirely: there is more value in engineering knowledge retrieval than in anything adjacent to the safety case, and it is available years earlier.
Where our evidence stops: Tenhaw employs no safety engineers. We do not write, assess or sign safety cases, and we would treat any supplier who offered to as a warning sign. Our contribution is stopping a programme drifting across the line without noticing, and knowing when to stop and bring your safety function in.
Operators of essential services under the UK NIS Regulations, assessed by competent authorities against the NCSC's Cyber Assessment Framework, and EU operations in scope of NIS2, which since October 2024 has widened the sectors covered, placed accountability on management bodies and added supply chain security and fast incident reporting. IEC 62443 is the standard your OT engineering colleagues will quote back at you.
What it requires of an agent
Manage the risk, protect against attack, detect events, minimise impact, and report significant incidents inside tight windows. In OT terms most of that rests on segmentation: the boundary between corporate IT and the control domain exists precisely to stop things reaching across it. An agent is a new actor asking to cross, and the questions are what identity it holds, what it can read, and whether it can write anything at all.
Where programmes fall down
A pilot pulls historian data to a cloud model endpoint by a route the security function never approved, because the pilot was scoped as analytics rather than as an integration. Or the agent runs on a shared service account with standing privileges wider than any human's, which leaves the framework outcome on privileged access unanswerable and makes the logs useless, because agent activity cannot be told apart from human activity after the fact.
What our method does about it
We ask what identity an agent holds and what it can reach before we ask what it can do. Read-only by default, no write path into the control domain unless your OT security function designs it, dedicated non-human identities with a tested revocation path rather than shared accounts, and pilots run against mocked services or synthetic data so the hardest approval is not needed during the fastest-moving phase of the work.
Where our evidence stops: We do not perform OT penetration testing and we do not certify anything to IEC 62443. We design so your security function can approve, and we expect specialists to do specialist work. What Tenhaw holds as a supplier is published on the security page.
Assurance frameworks: ISO/IEC 42001 and the NIST AI RMF
Global industrial groups, particularly those with US operations or US customers, and anyone whose procurement function has started asking suppliers how they govern AI.
What it requires of an agent
Neither is law. ISO/IEC 42001 is a certifiable management system for AI. The NIST AI Risk Management Framework is a voluntary structure organised around four functions, govern, map, measure and manage, with a generative AI profile alongside it. Their value is a shared vocabulary and a defensible record when a customer, an insurer or a board asks how AI risk is managed. The EU AI Act is where voluntary turns into obligation for anyone placing systems on the EU market. Its prohibitions have applied since 2 February 2025 and its general-purpose model rules since 2 August 2025, while the high-risk obligations were deferred by the 2026 AI omnibus to 2 December 2027 for stand-alone systems and 2 August 2028 where the AI sits inside a regulated product.
Where programmes fall down
The framework gets adopted as a document. A policy exists, a register exists, and neither is connected to what engineering actually does, so the gap between the stated control and the running system widens quietly until an audit finds it. Frameworks fail as paperwork and work as controls.
What our method does about it
We map what gets built to the functions rather than the other way round: an AI inventory generated from the systems themselves, evaluation results kept as records with the runs that produced them, and ownership recorded where the work happens. If you are heading for ISO/IEC 42001 certification, doing this during the build costs a fraction of doing it as a remediation programme afterwards.
Where our evidence stops: Tenhaw is not certified to ISO/IEC 42001. It is under assessment, and the security page says exactly where we are with it and with everything else. We are not a certification body or an auditor, and where you need a certified auditor, you need a certified auditor.
Tenhaw builds agentic systems and the operating models around them, and works alongside the risk, compliance, legal and actuarial functions who own the interpretation of these regimes. Our security and assurance position states what we hold today and what is still in progress.
If our evidence stops short of your regime, we will say so on the call rather than after.
The guides carrying the patterns this sector buys first. Each states its own evidence basis at the top: what we have delivered, and what is method rather than a build.
Industrial, Energy and Infrastructure: your questions
Where do industrial businesses get value from AI agents?
In engineering knowledge work rather than operational decisioning: retrieval across decades of technical documentation, simulation and scenario modelling that amplifies scarce specialist time, capital project reporting across distributed programmes, and compliance evidence gathering. Operational decisions in industrial settings are usually too consequential and too hard to reverse for early agentic autonomy.
Can an AI agent be part of a safety case?
Not comfortably, and it is the wrong place to start. A safety case argues, with evidence, that risks are reduced so far as is reasonably practicable, and that argument depends on the behaviour of the system being characterised. A system whose output is not reproducible is difficult to argue for, and a model your supplier updates on their release schedule breaks the argument silently. The realistic pattern is to keep agents on the analysis side of the boundary, make the boundary explicit so that crossing it is somebody's decision rather than a drift, require a management-of-change gate before a pilot touches anything safety-relevant, and pin model versions under change control your safety function owns. Tenhaw employs no safety engineers and does not write or assess safety cases.
Does NIS2 apply to AI systems in industrial operations?
NIS2 does not regulate AI as such. It regulates the security and resilience of entities in scope, and since October 2024 has covered more sectors, put accountability on management bodies and added supply chain security and fast incident reporting. An agent in an operator's estate is in scope like any other system. In OT the question is segmentation, and the boundary between corporate IT and the control domain exists to stop things reaching across it. An agent is a new actor asking to cross. UK operators of essential services face the same questions through the NIS Regulations and the NCSC's Cyber Assessment Framework, with IEC 62443 the engineering standard underneath. Design answers first: what identity does the agent hold, what can it read, and can it write anything at all.
What do ISO/IEC 42001 and the NIST AI RMF actually require?
ISO/IEC 42001 is a certifiable management system for AI: policy, roles, risk assessment, controls and evidence that they operate. The NIST AI Risk Management Framework is voluntary and organised around four functions, govern, map, measure and manage, with a generative AI profile alongside it. Neither is law, and both are increasingly what procurement and insurers ask about. The failure mode is adopting either as a document rather than as controls, so the register and the running system drift apart. Building the inventory, the evaluation records and the ownership trail during delivery costs a fraction of reconstructing them in a remediation programme. Tenhaw is not certified to ISO/IEC 42001. It is under assessment, and the security page says where that stands.
How do you run agentic transformation across distributed engineering teams?
By designing for asynchronous operation from the start. Tenhaw ran exactly this at Anglo American across the UK, Australia and the USA, building an agile blueprint lightweight enough that specialists onboarded fast, throughput data feeding simulation, and outcome-based milestones rather than project plans, so progress remained legible without synchronous coordination.
Has Tenhaw worked in heavy industry?
Yes. Tenhaw set up and ran the Data, Simulation and DevOps teams behind Anglo American's hydrogen-powered mining programme, work that underpinned a £40bn business case and spun out as First Mode. Tenhaw also made global delivery predictable at Yondr across data centre operations in the UK, US and Singapore.
Can an AI pilot use data from our plant historian?
Usually yes, provided it is scoped as an integration across the IT and OT boundary rather than as an analytics project. The failure we see is a pilot pulling historian data to a cloud model endpoint by a route the security function never approved, because nobody treated the agent as a new actor crossing a boundary built to stop exactly that. Our defaults are read-only access, a dedicated non-human identity with a tested revocation path rather than a shared service account, and no write path into the control domain unless your OT security function designs it. Early work runs against mocked services or synthetic data, so the hardest approval is not blocking the fastest-moving phase.
Our bottleneck is a handful of senior specialists. Can agents help?
That is the first place we look in this sector. Deep domain expertise sits with a small number of highly qualified people whose time is the actual constraint on the business, so an agent that amplifies scarce expertise is worth far more than one automating work you have plenty of. In practice that means simulation and scenario modelling, so a specialist can explore ten scenarios rather than two, and analysis prepared to the point where their judgement is the only thing still required. Expect scepticism from those same people, and expect it to be well-founded. You earn it with evidence on their own problems.
Our technical documentation is on-premise and unstructured. Can agents use it?
Yes, and it is usually where we would start here. Engineering knowledge retrieval across decades of technical documentation is the first place we look, because that material holds hard-won judgement that is otherwise locked in a filing system. Unstructured is normal and manageable. Tenhaw deploys on client infrastructure under your policies, with UK data residency by default, so on-premise is not a blocker either, and the documents never need to leave your estate to become retrievable. What the constraint really changes is sequencing. Expect early effort to go into access and structure before the impressive demos appear, and plan for it.
How do you show AI value when capital cycles run in years?
By separating the asset business case from the workflow business case. Capital cycles mean the case for the asset itself is measured in years, and nothing about agentic AI changes that. The workflows around the asset move on much shorter cycles. Capital project reporting consolidated across distributed programmes, compliance evidence gathering where the audit trail is the deliverable, and engineering knowledge retrieval all return value on the cadence of the work rather than the asset lifecycle. Engagements here are retainer-shaped rather than milestone-shaped, and Tenhaw reports measurable value every month, counting a month that delivers none as a failed month. That keeps a long programme honest while the asset case takes its own time.
Can an agent write anything into our control system?
Not by default, and not unless your OT security function designs the path itself. Our default is read-only across the IT and OT boundary, with no write path into the control domain, because that segmentation exists precisely to stop things reaching across it. An agent is a new actor asking to cross, so it gets a dedicated non-human identity with a tested revocation path rather than a shared service account, and its activity can be told apart from a person's afterwards. It is also where the value is not. In this sector the return sits in the analysis that informs decisions rather than in the decisions themselves, and anything informing a safety-relevant judgement needs a management-of-change gate before the pilot.
What happens if the model gets updated after we sign off a workflow?
Treat it as a change, because that is what it is. A supplier updating a model is a change whether or not anyone in your organisation initiated it, and any change to a safety-related system triggers management of change and reassessment. The awkward part is that the update lands on the supplier's release schedule rather than yours, so our default is pinned model versions with change control your safety function owns. An update then becomes a decision you take on your own timetable rather than an event you discover. We also keep evaluation results as records alongside the runs that produced them, so moving version gives you a measured before and after rather than a difference of opinion.
How do we stop an AI tool drifting into safety-critical use?
Name the boundary, and make crossing it somebody's decision. A tool arrives as decision support, becomes the thing operators actually rely on, and no management-of-change assessment is ever triggered because nothing in the control system changed. That is how the line gets crossed, by drift rather than by decision. So we write down which human judgement the workflow informs, design the point where a person is required rather than leave it to a line in the training pack, and treat any use that starts informing a safety-relevant judgement as a management-of-change gate before it goes further. Our contribution is seeing that line coming and bringing your safety function in before it is crossed.
Which teams need to be in the room: OT security, safety or engineering?
All three, at different moments, and the order matters. Engineering leads, because the value in this sector is engineering knowledge work: retrieval across technical documentation, simulation that amplifies scarce specialist time, capital project reporting across distributed programmes. OT security joins while the work is still a design, rather than after it has quietly become an integration that nobody scoped as one, since we ask what identity an agent holds and what it can reach before we ask what it can do. Your safety function is needed where a workflow informs a safety-relevant judgement, and that is the moment to stop and involve them, not the month after the pilot.
Can agents take the coordination load off teams in three time zones?
Yes, and it is a real source of value here. Engineering and delivery teams spread across three continents make asynchronous working a necessity rather than a preference, and the cost of that shows up as waiting when a question asked at five in London is answered tomorrow. Agentic workflows that assume a synchronous team in one time zone do not survive contact with that reality. So we design so that no step needs a particular person awake, and put agents on the assembly work in between, keeping the written record current so the next time zone starts from something. Tenhaw made global delivery predictable at Yondr across the UK, US and Singapore, though that was delivery discipline rather than agents.
Can an agent pull capital project reporting together across a programme?
Yes, and it is one of the first places we look in this sector. Consolidating capital project reporting across distributed programmes is knowledge work, where the inputs are trackers, documents and reports in different formats from teams in different time zones, and the effort goes into assembling a consistent picture rather than deciding anything. That makes it good agentic territory, because a person still reviews the output, and it is the same person who would otherwise have assembled it by hand. It also stays well clear of the control domain, so it can move at its own pace while the safety-adjacent conversation takes as long as it needs to take.
Can agents assemble compliance evidence across sites and systems?
Yes, and it is often the soundest first workflow here, because the audit trail is the deliverable rather than a by-product. The work is finding, citing and assembling evidence that already exists across systems and sites, which is retrieval with a paper trail attached, and a person still signs. Two design points carry it. Every item cites the source it came from, so an assessor can follow it back rather than take the summary on trust. And the model version and the run that produced each answer are kept as records, so the same question can be reconstructed months later. It also never reaches across the boundary into the control domain.
Our specialists have no spare time. How much of it will you need?
Less than a project would take, and in short structured blocks rather than a standing commitment. We design around sessions to set the problem, judge outputs and correct them, with the long stretches of work happening without your specialists in the room. Early work runs against mocked services or synthetic data, so their time is not spent unblocking approvals during the fastest-moving phase. We pair with your permanent engineers as we build, with measured skill transfer, because the point is to leave capability behind rather than a dependency on us. The AI Readiness Audit works the same way: four weeks, £44,000 fixed, sitting with the people who do the work rather than issuing a survey.
