One Platform to Control Every High-Risk Work Activity
Permit to work, SIMOPS management, isolation management, and risk assessments — unified in a single auditable Control of Work platform built for the energy sector. Every action captured. Every authorisation traced. Nothing left to paper.
Fragmented work control creates the gaps where incidents happen
Most high-hazard incidents don't occur because safety rules don't exist — they occur because those rules are fragmented across separate systems, manual registers, and ad hoc spreadsheets. When your permit to work, isolation register, SIMOPS log, and risk assessments live in different places, the connections between them are invisible until something goes wrong.
Elisian's Control of Work platform closes those gaps. Permits link directly to isolation points. Simultaneous operations are visible in real time before work begins. Risk assessments are attached to permits, not buried in a filing cabinet. And every action, authorisation, and sign-off is captured in a tamper-proof audit trail available for inspection at any time.
Built specifically for high-hazard energy operations — offshore oil and gas, gas transmission, and complex onshore facilities — Elisian is the Control of Work platform your duty holders, area authorities, and compliance teams can actually rely on.
Everything you need to control high-risk work across your operation
Elisian's Control of Work platform covers the full safe work management lifecycle — from permit issuance and isolation management through to SIMOPS coordination and audit-ready compliance reporting.
-
Permit to Work
Structured digital workflows for raising, reviewing, and approving permits with role-based sign-off at every stage — from initial request to final closure. Learn more about our PTW module.
-
SIMOPS Management
Real-time visibility of all concurrent work activities across your site. Identify and assess interaction risks between simultaneous operations before work begins, and apply controls directly within the permit workflow.
-
Isolation Management
Digital locked valve register linked directly to active permits. Every energy isolation point is recorded, authorised, and visible to all relevant parties — eliminating the disconnection between the permit and the isolation.
-
Risk Assessments
Structured digital risk assessments attached directly to permits. Hazard identification, control measures, and residual risk ratings are always linked to the work they authorise — not stored separately and referenced later.
-
Competency & Authorisation Control
Assign permits and isolation tasks to competency-verified individuals. Role-based approval chains enforce your site's authority structure — no one can authorise work outside their defined competence level.
-
Audit Trail & Compliance Reporting
Every permit action, isolation change, SIMOPS assessment, and risk control decision is permanently recorded and reportable — supporting HSE inspections, incident investigations, and internal safety reviews.
From work request to sign-off — every step controlled and connected
Elisian connects every element of your Control of Work process in a single digital workflow. Permits, isolations, SIMOPS assessments, and risk documentation are linked together from the moment a work request is raised.
-
Work Request & Risk Assessment
The requesting party raises a digital work request and completes a structured risk assessment — specifying the work type, location, hazards, and required precautions. The system validates completeness and flags any interaction risks with existing open permits before routing for authorisation.
-
Isolation Planning & Permit Authorisation
Required energy isolations are planned and recorded within the system before the permit is approved. The authorisation chain — from area authority through to issuing authority — reviews both the permit and the isolation schedule, with each sign-off timestamped and attributed to a named, competency-verified individual.
-
Live Work & SIMOPS Monitoring
Open permits and active isolations are visible in real time across your site. Supervisors and OIMs can view all concurrent work activities, assess SIMOPS interaction risks, and identify conflicts instantly — without relying on manual boards or radio updates.
-
Closure & Reinstatement
Permits and isolations are closed out within the system — with reinstatement steps verified by authorised personnel and every action permanently recorded. Final closure confirms the work area is safe and all energy sources have been reinstated, leaving a complete, immutable record.
Wood CATS — Gas Transmission
Wood's CATS (Central Area Transmission System) operation manages a high-pressure subsea gas pipeline running over 400km from the central North Sea to Teesside. With a previous digital system that no longer met operational requirements, Wood turned to Elisian to replace it and extend Control of Work capabilities across the asset.
Elisian's platform was deployed across Permit to Work, Isolation Management, Handovers & Events, Joint Integrity Management, and Safety Overrides — giving Wood's team unified, auditable control of all high-risk work across the entire transmission system.

- What is Control of Work software?
- Control of Work (CoW) software is a digital platform that manages every aspect of authorising, planning, and executing high-risk work on industrial sites. It typically encompasses permit to work, SIMOPS management, isolation management, and risk assessments — giving operators a single, auditable system to control all hazardous work activity.
- What is the difference between Control of Work and Permit to Work?
- Permit to Work is a specific authorisation process within the broader Control of Work framework. Control of Work covers the full lifecycle of safe work management — including SIMOPS planning, isolation management, risk assessments, and competency verification — with PTW as the primary mechanism for authorising individual activities. A CoW platform brings all of these together in one integrated system.
- How does Elisian's Control of Work software handle SIMOPS?
- Elisian provides real-time visibility of all open permits across a site, making it straightforward for area authorities and offshore installation managers to identify simultaneous operations, assess interaction risks, and apply appropriate controls. Permits link directly to isolation registers and risk assessments, so SIMOPS conflicts are visible before work begins rather than discovered after.
- Does Elisian's CoW platform include isolation management?
- Yes. Elisian includes a digital locked valve register and isolation management module that records every energy isolation point directly within the permit workflow. Isolation status is always linked to the active permit, visible to all authorised parties, and captured in a tamper-proof audit trail.
- How does Control of Work software support regulatory compliance?
- Every action in Elisian's platform is timestamped, attributed to a named individual, and permanently recorded. This tamper-proof audit trail supports compliance with HSE requirements, PSSR, DSEAR, and other UK regulatory frameworks — and provides the evidence trail required for regulatory inspections, incident investigations, and internal safety reviews.
- Which industries use Elisian's Control of Work platform?
- Elisian's Control of Work platform is used across offshore oil and gas, high-pressure gas transmission, and onshore processing operations. It has been deployed on complex assets including the CATS North Sea gas transmission system, and is suitable for any high-hazard energy sector operation requiring a rigorous, auditable approach to safe work management.
