Yokogawa’s OpreX™ Control of Work places risk assessment and safety at the core, supporting intelligent safe and consistent operations management across everyday maintenance activities.
OpreX™ Control of Work is Yokogawa’s integrated Control of Work solution for managing risk controlled work and operational safety in hazardous and highly regulated environments.
Built on over 30 years of Control of Work experience, it brings together permitting, risk control, mobile execution, and operations management to support a consistent, auditable integrated Control of Work solution for managing risk controlled work across the full lifecycle of work.
OpreX™ Control of Work goes beyond electronically replicating paper permits. It embeds risk awareness and verification directly into how work is planned, authorised, executed, and monitored—integrating permitting with operations management, shift handover, incident management, AI-powered RAMS, and mobile field execution through Field Assistant to support a consistent, auditable Safe System of Work.
OpreX™ Control of Work supports advanced digital deployment while integrating with existing site systems and workflows.
Robust Risk Assessment identifying all hazards present in the workplace that have the potential to cause harm enabling the necessary control measures to mitigate the risk.
A comprehensive yet simple to use Isolation module, allowing users to ensure that all energy sources associated with any equipment to be worked on, have been completely removed.
Digital Permit to Work is your front-line method of keeping people safe. Providing risk identification, mitigation, and communication key components of safe Control of Work.
Mobile execution for safer, more efficient field operations Field Assistant is the mobile enablement layer within OpreX™ Control of Work, extending digital Control of Work processes directly to the point of work.
OpreX Control of Work's SORM - Safety Override Risk Management module offers visibility of current, future and historical permitting workload and highlights “overload risk” and provides additional dashboarding and reporting functionality specific to these in order to ensure operational risk management for process safety.
Reporting in OpreX Control of Work allows the user to create and run reports using current and historical data derived from all Job, Task, Isolation and Personnel activity in the system. For example, a report could be created showing all permits completed in an area over a given time period.
The speed at which permits can be issued during turnarounds can have a large effect upon overall performance, with any delays in issuing impacting upon the time taken to get the job done. RA-P4’s upfront planning capability, its flexible rules and barcode controls greatly enhance this process giving potential for large savings.
The solution can be configured to use plot plans/maps hosted by WMS (Web Map Service) servers.
The Competence Classroom eLearning portal offers training to workers in an organisation for all modules, Permit to Work, Isolations, and Administration. The portal will enable basic users to receive training in basic tasks.
The Utilities and Infrastructure module has been developed to cater for businesses with widely distributed asset bases and where a high degree of communication between consenting and affected parties is crucial.
Electronic Management of Change (eMoC) within OpreX™ Control of Work provides a structured, auditable approach to managing temporary and permanent changes that can impact safety, operations, and compliance.
Operator Driven Reliability (ODR) enables frontline operators to carry out routine inspections and basic maintenance tasks to identify early signs of equipment degradation and prevent failures.
P&ID’s are now an indispensable source of information for many software solutions. Being able to communicate a vast amount of engineering information about a site is now essential for a wide variety of requirements.
Shift Management within OpreX™ Control of Work provides a structured, auditable approach to capturing, managing, and handing over critical operational information between shifts.
By guiding users through hazards, controls, and safe work methods in a clear, step‑by‑step approach, AI driven SMART RAMS help ensure consistency, compliance, and shared understanding across all parties involved in the work.
Incident Management within OpreX™ Control of Work provides a centralised, auditable approach to capturing and managing incidents, accidents, and near misses across operational sites. Embedded directly within the Control of Work environment, it supports consistent reporting, clear ownership, and full traceability from initial report through to close out.
Field Standard Operating Procedures (FSOP) extend OpreX™ Control of Work by enabling standard operating procedures to be executed, verified, and recorded digitally in the field.
