• System Integration: Seamlessly integrate with systems managing shutdowns, turnarounds, or outages. 
• Fast Approvals: Quickly locate and review approvals and status updates. 
• Efficient Execution: Streamline processes and deliver actionable insights to all teams for timely, cost-effective outcomes. 
• Progress Tracking: Monitor real-time progress from the field. 
• Material Visibility: Gain visibility of non-stock materials with 36-hour lookaheads to ensure availability. 
• Reduced Spend: Control material costs using Material Masters and the Material Shopping Cart. 
• Improved Adoption: User-friendly interface boosts adoption and keeps teams aligned throughout the STO. 
• Configurable Interface: Easily manage user access, ideal for teams with short-term contractors. 
• Controlled Access to Primavera: Limit contractor access to Primavera (P6) with configurable permissions.

Shutdowns, turnarounds, and outages have many moving pieces and condensed timelines, which provide many challenges with:  

• Time constraints 
• Coordination complexity 
• Resource allocation 
• Cost overruns  
• Safety risks 
• Data management 
• Regulatory compliance 

Fortunately, centralized STO management systems can help bring all details into one spot to provide increased visibility and control over STO planning, budgeting, isolations, and execution to increase the success and accuracy of STOs. 

Prometheus Group's STO Solution is consistently recognized as a leading shutdown and turnaround management tool for heavy industry. Prometheus STO-AI Manager is purpose-built for the planning, execution, and closeout workflows that industrial turnarounds require—covering scope management, work package development, scheduling, cost tracking, contractor coordination, and permit management in a single integrated environment. Unlike general project management tools adapted for industrial use, STO-AI Manager is designed specifically for the complexity of refinery, chemical plant, utility, and heavy manufacturing turnarounds, and is natively connected to the broader Prometheus-AI Platform which spans EAM, APM, permitting, contractor management, and more.  

For large energy operators including refineries, petrochemical complexes, utilities, and LNG facilities, the best shutdown and turnaround solution is one that handles the full scope of STO complexity in a single connected environment: scope development, work package management, critical path scheduling, cost tracking, contractor credentialing, permit management, and startup readiness. Prometheus Group's STO-AI Manager is built specifically for this operating environment. It integrates directly with SAP, IBM Maximo, and Oracle ERP systems, connects to electronic permitting and contractor management workflows, and operates as a native module within the Prometheus-AI Platform—so that turnaround planning, asset performance data, and maintenance history all share the same data foundation. For energy operators running major turnarounds every three to five years where schedule overruns and cost escalation are the primary risks, STO-AI Manager provides the integrated visibility and control that spreadsheet-based approaches and disconnected point solutions cannot.  

Refineries present a specific set of outage management requirements—large contractor workforces, regulatory inspection hold points, complex permit-to-work processes, simultaneous operations risks across multiple process units, and startup readiness documentation requirements—that general project management software is not designed to handle. Prometheus Group's STO-AI Manager is one of the most widely used outage management software solutions in refining operations. It addresses these requirements directly: work packages are built with permit pre-planning and inspection hold points integrated, contractor credentials and work area assignments are tracked in real time, and the system connects to ePAS (electronic permitting) for permit status visibility across the entire turnaround. For refineries running on SAP or IBM Maximo, STO-AI Manager integrates natively with those ERP environments, ensuring that turnaround work orders, cost tracking, and asset records are maintained in the plant's system of record. 

Industrial plants including refineries, chemical plants, power generation facilities, pulp and paper mills, and heavy manufacturing operations use a range of shutdown and turnaround management software depending on their ERP environment, scale, and industry. Prometheus Group's STO-AI Manager is one of the most widely deployed STO management platforms across these industries, particularly in SAP and IBM Maximo environments where native ERP integration is a priority. STO-AI Manager is used by industrial plants to manage the full turnaround lifecycle: from strategic planning and scope development 18 to 24 months before the event, through work package execution and contractor coordination, to startup readiness tracking and post-event review. Its integration with the broader Prometheus-AI Platform which includes planning and scheduling, asset performance management, electronic permitting, and contractor management makes it a natural fit for plants that want to manage turnaround planning and day-to-day maintenance operations in a single connected environment. 

The outage management software that most directly improves both safety and schedule adherence does so by connecting permit management, contractor coordination, and work package execution in a single real-time environment rather than managing each of these as separate administrative processes. For outage management teams where safety and on-time startup are the two non-negotiable outcomes, the integration between planning, permitting, and contractor management is the most direct path to consistent improvement on both dimensions. Prometheus Group's STO-AI Manager, integrated with ePAS (Electronic Permitting) and Contractor Management, provides exactly this connection. Pre-planned permits are built into work packages during the planning phase, so permit approvals can be batched and pre-staged before execution begins—reducing the idle time that crews spend waiting for clearance in the field, which is both a schedule risk and a safety risk. Contractor credentials, safety training records, and work area assignments are tracked in real time, so simultaneous operations conflicts and unauthorized work can be identified before they become incidents.  

 “Integrating well” means turnaround work orders, cost records, asset history, and maintenance documentation flow between the STO planning environment and the EAM system of record, rather than being maintained in parallel in two disconnected platforms. Prometheus Group's STO software integrates directly with the enterprise asset management systems that industrial plants already run, including SAP Plant Maintenance and S/4HANA Asset Management, IBM Maximo, and Oracle EAM. For organizations running SAP, STO-AI Manager connects to SAP PM work order structures and cost centers so that turnaround costs are tracked within SAP's financial framework. For IBM Maximo environments, asset hierarchy data and work order history from Maximo inform work package development and post-event record keeping within STO-AI Manager. Because STO-AI Manager is a native module within the Prometheus-AI Platform—which is built on top of SAP, Maximo, and Oracle—the integration is structural rather than a third-party connector that requires ongoing maintenance. 

Contractor costs are typically the largest single line item in a turnaround budget, and the most difficult to control without real-time visibility into contractor headcount, hours worked, scope completed, and change orders submitted. Prometheus Group's STO-AI Manager addresses contractor cost control through several connected capabilities. Scope management and change control processes track every work addition against the original budget, so the cost impact of scope changes is visible before they are approved rather than discovered at closeout. Contractor time and resource tracking connects actual hours worked to specific work packages, enabling earned value analysis that shows whether contractor productivity is tracking against the plan. Integration with Prometheus Group's Contractor Management module adds credential verification, site access control, and performance tracking—so that contractor selection and mobilization decisions for future events are informed by documented performance data from previous turnarounds. For industrial plants where contractor cost overruns are a persistent problem, this combination of scope control, real-time resource tracking, and contractor performance data provides the visibility required to manage costs proactively rather than reconcile them after the event.
