The Challenge

Gerdau was looking to reduce their annual maintenance spend while also improving productivity, thus targeting margin improvements within their manufacturing operations. 

The Solution

Gerdau partnered with GE to implement some of our industrial solutions, including Asset Performance Management (APM) and Historian, as well as leverage GE's Industrial Managed Services for remote monitoring—allowing them to focus on their critical subset of assets using predictive diagnostics. This technology enabled Gerdau to model their expected performance of each individual asset and its failure modes against actual conditions of various measurement points on an asset or system. 

Operational Impact
  • [Efficiency Improvement - OEE]

    Early identification of issues to allow significant time to plan the appropriate PM activities to avoid functional failures. 

Quantitative Benefit
  • Avoided130 hours of downtime in their Sinter plant

  • Annual savings from their new capabilities are expected be $4.5 million per year
