Go Arc is a manufacturing operations management platform, a SaaS platform that aggregates data from an entire manufacturing facility and breaks down conventional silos of knowledge and data by analyzing field safety reports from safe-connected workers. This includes the analysis of data from ERP systems, OT, and IoT sensors.

Ensuring a safe working environment and reducing work incidents in high-risk operations with changing processes and risk levels during multiple types of maintenance jobs.

An integrated work permitting system

  • An automated, connected, digital system to connect between all sites and parties involved
  • Real-time data communication and visualization from the field
  • Adaptable to changing conditions and risks, with full visibility to optimize the authorization process
  • To provide a reliable flow of information and notification across the internal chain of command to enhance communication

A connected worker solution for dynamic authorization

  • Digitize and standardize safety processes and procedures
  • Real-time hazard identification and risk evaluation
  • Facilitate continuous worker, asset, and process safety
  • Improve accessibility of permits & identify real-time permit conflicts
  • Proper safety protocols

I never would have thought having the Operations and Maintenance Supervisor as part of the actual permit would be good, but now with the new permit system, all parties are involved and knowledgeable.

  • Digital Transformation Towards The Refinery of the Future

    Delek US and GOARC worked together to define, design, develop, and implement a unique systemic digital solution that includes Permit to Work (PTW), job specific risk management, hazard identification, and establishment of safety protocols, combined in one system. 

    Based on real-time data integration for cumulative risk evaluation the innovative software solution identifies overlapping permits, safety hazards, and risk levels for dynamic work reallocation. The system supports a connected environment with 24/7 communication to enable optimal risk level evaluation, decision-making and management across workers and assets.  

  • Transformational change: Integrating all processes and data sources

    A single source provides full, interactive visibility of all site activities and is accessible to everyone.  The control screen shows all existing work permits, identified hazards, reported changes, and real-time status of employees and tasks in the field.  The integrated technology combines all processes and data sources to provide a comprehensive and continuously updated picture for situational awareness and effective, proactive risk management.

  • Dynamic Risk Management

    The dynamic solution identifies the best and most effective workflow and signature authorization in real time and identifies issues, such as hazardous work conflict and overlapping permits to enable more effective work reallocation.  The system delivers updated personalized and specific safety guidelines and notifications to workers.

  • Risk Valuation

    Risk visualization and real-time synchronized safety and process-related controls in a connected environment enable informed and rapid decision-making.

The rollout of the new digital Permit to Work solution has improved accessibility of permits in a standard format, with real-time identification of permit conflicts and the ability to effectively suspend work and resolve issues, significantly reducing work incidents.   


The cost-saving digital system shortens the time and labor required to issue each permit. The system enables efficiency capture during controlled plant shutdowns, maximizing safety performance and minimizing risk while leading to increasing production revenue. 

The Delek Tyler refinery had challenging safety performance. Post roll-out, with the change in safety culture, the refinery achieved a record 1045 days without a single injury.  The new system went live in September 2020 in the Delek El Dorado refinery and was successfully stress tested during the January 2021 turnaround.
