SAM GUARD^®

AI Predictive Maintenance for the Process Industry

Optimize Your Plant with SAM GUARD^®

Improved reliability.

Gains in production.

Reduced costs and downtime.

AI-Powered Software

Human-enhanced machine learning software that detects equipment failures and process deviations in the very early stages, well before human or DCS Alerts.

Features include:

AI-powered early alerts: prepare a plan of action, long before the discovered issues have a significant impact on your plant. The earlier you detect a failure, the less it costs to repair it and the equipment is most often still recoverable.
Unsupervised and supervised AI: ensure that you receive alerts on known or repeating issues in addition to discovering unknown issues without human guidance.
Data security: SAM GUARD^® is ISO 27001 certified and can be hosted on-site or in the cloud.

How the Software Works

We create a Digital Twin of your plant in the software, mapping all relationships between data tags and the process.

SAM GUARD^® creates an AI Causality Network unique to your facility which can be adjusted over time as your plant changes.

Using 13 months of historic data, SAM GUARD^® creates multivariate statistical normality clusters which are continuously updated. These baselines trigger SAM GUARD’s alerts.

SAM GUARD^® process specialists meet weekly with your on-site team to review alerts, analyze process data, determine root causes, and set maintenance tasks.

Use Case 1

At a petrochemical plant, SAM GUARD^® identified the abnormal behavior of a control valve and generated an alert about it. The receiver tank level set point was unchanged, but the stroke of the valve was fluctuating by up to 100% (see left). Maintenance engineers inspected and calibrated the valve in place, rechecked, and found that the valve was not sealing, so they replaced it. When disassembling, they discovered that the valve plug had eroded away.

Use Case 2

At a remote piece of mining equipment, SAM GUARD^® detected a leak in a sealant line long before anyone would have been physically present to notice.

SAM GUARD^® detects failures before process parameters exceed single variable upper or lower control limits by monitoring multi-variate norms – in this case sealant flow and motor temperature.
