- [Critical Equipment Integrity for Data Centres: From Electrical Testing to Ongoing Assurance](https://www.elisian.co.uk/critical-equipment-integrity-for-data-centres-from-electrical-testing-to-ongoing-assurance.html): Data centre electrical testing shouldn't be a yearly tick-box exercise — see how criticality tiers and defect tracking build real integrity assurance.
- [Why Joint Integrity Management Matters Offshore](https://www.elisian.co.uk/why-joint-integrity-management-matters-offshore.html): A practical look at why offshore joint integrity, isolations and control of work need to function as one system, not separate maintenance tasks.
- [Why Scaffold Management Matters on Industrial Sites](https://www.elisian.co.uk/why-scaffold-management-matters-on-industrial-sites.html): Scaffolding is one of the most common temporary structures on any industrial site, yet it is often treated as a background detail rather than a managed asset. Poorly managed scaffolding creates safety risks, slows down projects, and adds unnecessary cost. Treating scaffold management as a core part...
- [Electrical Permit to Work: A Practical System Guide for Data Centres and Contractor Sites](https://www.elisian.co.uk/electrical-permit-to-work-a-practical-system-guide-for-data-centres-and-contractor-sites.html): Generic permit software treats electrical work as one hazard among many. Here's how to build an electrical permit to work system suited to real data centre risk.
- [Wind Turbines on Oil and Gas Platforms: What Integration Guidance Means for Control of Work](https://www.elisian.co.uk/wind-turbines-on-oil-and-gas-platforms-what-integration-guidance-means-for-control-of-work.html): Adding wind turbines to an oil and gas platform, or co-locating a platform with a nearby offshore wind array, sounds like a straightforward energy transition story. In practice, it raises a set of control of work questions that most operators have not had to answer before. Two industries with differ...
- [Control of Work When Wind Meets Oil and Gas: The Operational Assurance Challenge Nobody Is Talking About](https://www.elisian.co.uk/control-of-work-wind-oil-gas-integration.html): The integration of offshore wind generation into oil and gas facilities is one of the most significant operational changes the UKCS has undertaken in a generation. The safety case implications, the duty holder responsibilities, and the control of work challenges that come with it are only beginning to be understood — and the management systems on most assets were not designed for them.
- [Process Safety Management in Onshore Terminals: What Operators Get Wrong](https://www.elisian.co.uk/process-safety-management-onshore-terminals.html): Onshore terminals — gas processing facilities, pipeline terminals, and bulk liquid storage sites — operate under the same process safety obligations as offshore installations. The regulatory framework is equally demanding. The safety culture, in many cases, is not.
- [How Digital Permit to Work Reduces Insurance Risk in the Energy Sector](https://www.elisian.co.uk/digital-permit-to-work-insurance-risk.html): Insurers covering energy sector assets are asking harder questions about control of work than they were five years ago. The facilities that can demonstrate a robust, evidenced permit to work system are not just managing safety risk better — they are managing their insurance position better too.
- [What Is a Temporary Equipment Register — and Why Does Yours Probably Have Gaps?](https://www.elisian.co.uk/temporary-equipment-register-gaps.html): Temporary equipment on an operating asset is one of the most consistently undermanaged areas of operational assurance. It arrives on site, gets deployed, and can remain in use — and in some cases in place — long beyond its approved period if the register is not actively managed.
- [What Is an Isolation Register — and Why Does It Matter?](https://www.elisian.co.uk/isolation-register-permit-to-work.html): An isolation register is one of the most important documents on any industrial site. It is also one of the most commonly misunderstood — treated as a record of what has been isolated rather than as an active control that governs whether people can work safely.
- [Contractor Safety Management on Complex Industrial Sites: Where the Gaps Are](https://www.elisian.co.uk/contractor-safety-management-industrial-sites.html): Most serious incidents on industrial sites involve contractors. Not because contractors are less competent than direct employees, but because the systems designed to keep them safe often assume a level of integration and oversight that does not exist in practice.
- [What Is a Safety Critical Element — and How Should You Be Managing Them?](https://www.elisian.co.uk/safety-critical-elements-management.html): Every offshore installation and major hazard facility has safety critical elements — the physical barriers and systems that stand between a hazardous event and a major accident. Knowing what yours are is the starting point. Being able to demonstrate that they are performing to their required standard is what the regulator actually asks for.
- [Lone Worker Safety in the Energy Sector: Where Permit to Work and Operational Assurance Must Work Together](https://www.elisian.co.uk/lone-worker-safety-energy-sector.html): Working alone in an industrial environment is not inherently prohibited under UK law — but it carries obligations that many energy sector operators are not fully meeting. When something goes wrong with a lone worker, the question is never whether a policy existed. It is whether the system around that worker actually kept them safe.
- [Shift Handover Best Practices for Offshore Operations](https://www.elisian.co.uk/shift-handover-best-practices-offshore.html): More incidents in offshore operations occur in the first two hours of a shift than at any other point in the working day. The reason is almost always the same: the incoming team did not have an accurate picture of what the outgoing team left behind.
- [The Hidden Cost of Paper-Based Permit to Work Systems](https://www.elisian.co.uk/hidden-cost-paper-permit-to-work.html): Paper-based permit to work systems are not free. They carry costs that rarely appear in a budget line — until an incident, an audit finding, or a near-miss makes them visible all at once.
- [Hot Work in Data Centres: Why the Permit Requirements Are Stricter Than You Think](https://www.elisian.co.uk/hot-work-permit-data-centres-uk.html): Hot work in a data centre is not like hot work anywhere else. When you isolate a smoke detector to carry out welding or grinding, you are simultaneously removing the early warning system for a fire in a building full of energised equipment, combustible cabling, and raised floor voids that can carry a fire invisibly from one zone to the next.
- [Electrical Work in UK Data Centres - What a Permit to Work System Must Cover](https://www.elisian.co.uk/electrical-permit-to-work-data-centres-uk.html): The Electricity at Work Regulations 1989 apply to data centres as directly as they apply to any power station or refinery. Yet many UK data centre operators are managing electrical work through informal controls that would not withstand HSE scrutiny or survive an incident investigation.
- [What Does Good Process Safety Look Like in 2026?](https://www.elisian.co.uk/process-safety-2026.html): Process safety has never been more scrutinised — by regulators, insurers, and operators themselves. In 2026, the question is not whether your facility has a process safety management system, but whether it actually works under pressure.
- [Elisian Retains ISO/IEC 27001:2022 Certification — What It Means for Our Clients](https://www.elisian.co.uk/iso-27001-2022-certification-retained.html): Elisian has successfully retained ISO/IEC 27001:2022 certification for another year. For clients operating in high-hazard industries, here is what that certification actually covers and why it matters to your operations.
- [Why Data Centres Need a Formal Permit to Work System](https://www.elisian.co.uk/permit-to-work-data-centres.html): Data centres are high-hazard operational environments — high-voltage electrical systems, confined spaces, suppression systems, and continuous critical load. Yet many still control high-risk maintenance work through informal approvals and paper-based processes. Here's why that needs to change.
- [What is Operational Assurance in Offshore Wind?](https://www.elisian.co.uk/operational-assurance-offshore-wind.html): As offshore wind operations mature, the gap between construction-phase safety culture and long-term operational discipline is becoming clear. This article explains what operational assurance means for offshore wind operators — and why the sector can't afford to learn this lesson the hard way.
- [How to Build a Locked Valve Register That Passes Audit](https://www.elisian.co.uk/locked-valve-register-audit.html): A locked valve register is one of the most audited documents in any oil and gas operation. This guide explains what auditors look for, where paper-based registers fail, and how to build one that holds up under scrutiny.
- [What is Operational Assurance in Oil & Gas?](https://www.elisian.co.uk/operational-assurance-in-oil-gas.html): Operational assurance is how energy sector organisations confirm that their operations are running as intended — safely, compliantly, and in control. This article explains what it means in practice and why it matters.
- [Managing Joint Integrity During Shutdowns & Turnarounds - Why Digital Traceability Matters](https://www.elisian.co.uk/jointintegrity.html): Shutdowns and turnarounds put joint integrity programmes under intense pressure. Here's why structured digital management makes the difference between a clean restart and costly rework.
