Executive Summary
As one of the UK's leading Distribution Network Operators, SSEN Distribution required stable, verifiable data collection at scale across a growing range of asset types. Existing tools struggled with offline reliability and large data volumes, while system upgrades threatened operational continuity. Rather than pursue a costly replacement, SSEN Distribution commissioned CHiME - a field-friendly application built to integrate with existing systems and adapt rapidly to changing inspection demands. Eight years on, the results speak for themselves.
‍

The Operational Challenge

• Offline instability - field systems failed to maintain performance in low-connectivity environments.
• Data volume constraints - legacy tools hit their limits as inspection programmes scaled.
• Workflow disruption - system upgrades created gaps with no reliable fallback for field teams.
• Inflexible data collection - adapting question sets for different asset types was slow and resource-intensive.

How CHiME Solved It

• Seamless integration. Connects securely with existing work management systems - no disruptive IT changes required.
• Chimelets. Modular, configurable inspection question sets updated rapidly without added burden.
• Offline-first resilience. Reliable data capture continues through upgrades and remote locations alike.
• Expanded asset coverage. Substations, link boxes, LV pillars, subsea cable shore sites, and urban battery replacements - all in one platform.
• Standard devices, low TCO. No specialist hardware, no costly upgrades.

"CHiME gives us the flexibility to capture asset data in greater depth while working seamlessly, even offline, alongside our existing systems." - Gillian Thomson, Asset Systems Analyst, SSEN Distribution
