Mobile Plant Maintenance for GTSOU in partnership with EigenMethod

About the client

LLC Gas Transmission System Operator of Ukraine (GTSOU) is a natural monopoly responsible for transporting natural gas for customers in Ukraine and European countries. The company was established in 2019 as part of Ukraine’s international commitments to the Energy Community regarding the independence of the national gas transmission system operator.

The company’s primary objective is to ensure reliable, safe, and uninterrupted gas transportation while developing a transparent management system integrated into the European energy market.

Challenge

Imagine a section of a high-pressure gas pipeline somewhere between two villages: no connectivity, no electricity, and the nearest office dozens of kilometres away. These are exactly the kinds of locations where GTSOU field crews maintain the country’s critical infrastructure every day. Yet maintenance and repair processes were still largely paper-based.

• Paper as the primary information carrier: work schedules, work orders, reports, and defect logs were completed manually.
• A gap between field operations and the IT system: data was transferred with delays and then re-entered into the back end.
• Outdated information on equipment condition, completed work, materials used, and time spent.
• No unified digital trace: it was difficult to track who performed what work, when, and on which specific asset.
• Unnecessary travel between offices and field sites to receive assignments and submit reports.
• Risk of data loss in challenging conditions: without connectivity or power, work could effectively come to a halt.

For critical infrastructure at the national level, this meant slower response to technical issues, limited quality control, and a lack of up-to-date analytics for management decision-making.

Solution

In 2023, EigenMethod, together with MODUS X as a technology partner, began developing the Mobile Plant Maintenance solution for GTSOU on the SAP BTP platform, integrated with SAP S/4HANA.

The role of MODUS X

The team was engaged based on its previous experience: at DTEK Grids, MODUS X had already developed and implemented the Mobile Crews solution for power distribution networks, which is used daily by 1,500 employees across 850 field crews.

In the GTSOU project, MODUS X was responsible for four key areas: requirements definition and architecture consulting, participation in solution design, QA engineering, and strengthening the development team at critical stages.

Solution architecture

• Mobile application — a field crew tool for task management, work completion tracking, defect registration, and materials and time tracking.
• Web application — for task creation, work planning, automatic and manual assignment, and execution monitoring.
• SAP Connector — an integration service connecting the solution with SAP ERP using SAP’s internal data format.
• SAP S/4HANA — a unified digital environment for technical objects, work orders, notifications, material movements, and work confirmations.

Key features

• A personalized list of tasks for each shift, technical object hierarchy, and documentation — all available on a smartphone.
• Maps with optimized routes between sites.
• Equipment identification via RFID tags and automatic on-site operation tracking.
• Defect registration with symptom selection from reference directories, including photo and video attachments.
• Tracking of materials actually used and working time.
• Full offline functionality with automatic synchronization as soon as connectivity is restored.

Result

Beyond the quantitative results, the solution gave GTSOU a digital trace of every task, up-to-date infrastructure analytics in SAP, and an additional layer of protection for critical infrastructure through full visibility into the condition of the gas transmission system.

International recognition

• Winner of the SAP Quality Awards 2025 for Central & Eastern Europe in the Business Transformation category. The award was presented to EigenMethod, with MODUS X acting as a technical subcontractor.
• Finalist of the SAP Innovation Awards 2025 — the first large-scale Ukrainian infrastructure project to reach the finals among more than 200 submissions from around the world.

“We took paper out of the field crews’ hands and gave them smartphones connected to our core IT system. Even when there is no connectivity or power, the crews can continue working and the data is not lost. The application has become our new standard for maintenance,” — Vladyslav Medvediev, Chief Operating Officer and Member of the Management Board at GTSOU.

“The partnership had two key areas: sharing expertise and strengthening development capacity. This kind of cooperation raises the quality bar for mobile solutions in the Ukrainian SAP market,” — Dmytro Osyka, CEO MODUS X.

Mobile Plant Maintenance transformed gas transmission infrastructure maintenance from a paper-based process into a unified digital system with real-time data access, offline resilience, and full SAP integration.

For GTSOU, it sets a new standard for maintaining critical infrastructure at the national level. For the Ukrainian market, it demonstrates that the local SAP ecosystem is capable of delivering world-class solutions even in wartime.
