Integrate Maintenance, Operations, Projects, and Safety

Maxavera provides plug-and-play integration between any ERP, EAM, CMMS, or EHS system. It intelligently transfers all necessary information such as work orders, operations/tasks, work centers, personnel, equipment, location details, permits, and any other information that needs to be shared between the software applications. Maxavera has preconfigured integration packs for common integration scenarios but has the flexibility to integrate nearly every software available, including homegrown solutions.


Industry-Leading Functionality - Maxavera comes with hundreds of pre-mapped fields and transformation logic between popular EAM, ERP, and CMMS software applications.

Users are able to run their own web-based user consoles, or they can schedule jobs to run autmatically.

Certified Integration - All integration solutions leverage the Maxavera Connector Studio (MCS) product when it comes to moving data in and out of the databases.

MCS was first certified by SAP in 1998 and has processed billions of transactions since. It is among the most proven integration technologies in the industry, and with additional product certifications added, it ensures future compatibility with new software releases.

Open Standards - Maxavera does not lock you into complex, expensive, proprietary middleware platforms and provides an end-to-end solution for your integration needs. Maxavera is open standards based and will run on any J2EE compliant application server platform including Apache Tomcat, BEA WebLogic and IBM WebSphere.

You are free to choose the platform that is right for your enterprise— and protected if you change your mind in the future.

Version Freedom - Maxavera utilizes a loose coupling architecture. This makes Maxavera independent from either side of the integration equation which eliminates the risk of version incompatibilities.

With Maxavera you can mix and match versions as your business requires and feel free to upgrade your systems independently without the risk of "breaking" your integration.

STO Execution

STO Execution is a state-of-the-art solution that integrates and extends your existing systems to create a single, unified command-and-control center for managing your TAR/Outages. Get more visibility and control than you ever thought was possible. It takes multiple systems to support the complex requirements of a major TAR/Outage.

Your organization already has a work order management system such as SAP PM, IBM Maximo, Oracle eAM or Ventyx Asset Suite, and you probably also use some type of specialty scheduling tool such as Oracle Primavera P6 or Microsoft Project to manage your critical path, scheduling and resource optimizations. Additionally, many plants use a variety of other special purpose applications for functions like permits, tag-out/lock-out, time management, boundaries, inspections and safety.

Key Benefits

Unified Outage Management System - Integrates all work order, schedule, clearance and RP data into a single unified view accessible to all members of your outage team from anywhere.
Simplified Progress Collection - Outage staff can make progress updates in a few seconds from any computer or connected device. No more waiting on paperwork or meetings to know what is happening in the field.
Real-Time Outage Schedule - Puts information in the hands of decision makers by providing a live interactive schedule that reflects job progress, delays and problems from the field in near real-time.
Automated Progress Collection - Continuously looks at the schedule looking for jobs that require progress updates based on various criteria and follows up with job owners to collect updates
Automated Schedule Analysis - Performs continuous real-time schedule monitoring and analysis looking for both risks to the schedule and opportunities to pull work forward.
Automated Job Alerts - Enables users to flag specific jobs that they would like to be kept apprised of. As feedback comes in from the field andthe status of these jobs changes the user is automatically notified of the condition change.
Shop and Ops Monitors - Monitors provide the maintenance and ops work control areas with real-time visibility to jobs that are delayed or ready-to-work by their department in the current and next shift windows
OCC Mission Control Monitors - Projects information to wall mounted screens in the OCC increasing visibility to the health of various areas of the outage, identifying both problems and opportunities.
Mobile Progress Collection - Collects progress updates directly from the field, performs an instant analysis, and notifies supervisors,schedulers and OCC management as needed.
Multi-System Data Integration - Integrates concurrently with all major systems involved in nuclear outage management including Ventyx Assset Suite, SAP, Maximo, Primavera, Ventyx eSOMS and others.
Dashboards and Reports - Get all of your outage management reports, KPI’s and dashboard views directly out of STO Execution

Use Cases

Refueling Outages - Refueling outages are complex, very fast moving projects. Communication and coordination between and among your team is absolutely critical to outage execution performance.

STO Execution is the industry’s first outage execution management system. It puts your team back in control, and gives them the opportunity to measurably improve outage performance and reduce costs. It streamlines business processes and delivers actionable information to the fingertips of the people that need it, even before they know they need it.

Unplanned Outages - Similar to a refueling outage, restoring your station to a production mode after an unplanned outage is a very fast moving, short-fused “project”. It requires exceptional communication and coordination among all parties and resources involved in execution of work.

STO Execution streamlines and optimizes restoration work the same way it does for refueling projects. It provides an exceptional communication and coordination framework that enables teams to execute together with greater efficiency and accuracy. The result is a better, faster and more reliable method of restoring your systems and getting your station back to Mode 1.

Capital Projects - Just as it is used to streamline and optimize refueling outage project execution, STO Execution’s advanced communication, progress collection, schedule analysis and resource coordination features can substantially improve the execution performance of any sufficiently complex project.

STO Execution provides an easy to use, standardized approach to extending project schedules to the parties involved in your project, collecting progress information, and communicating progress and problems to the right people throughout the project management structure.
