Case Study

OT Asset discovery for a Mining major

The client had engaged multiple partners to manage operational technology (OT) infrastructure across their mines located in over 20 locations across three continents. This approach resulted in inefficiencies and operations overhead without the requisite RoI and transformational innovation.

The discovery of existing OT assets in its “as-is” state is the first and foremost step towards a centralized technology platform. The client chose Infosys to carry out asset discovery assessment across all locations.

Key Challenges

  • Diverse set of legacy systems from many suppliers installed and commissioned at different times using different standards
  • Non-standard and unreliable information for inventory consolidation due to aging and lack of version management
  • Inconsistent input data from various sources, including tool extracts, installation reports, redline drawings, site photos and plant drawings
  • Retrieving data from multiple software and tools such as configuration and program backups
