Chevron Oronite Singapore

• Fuel and lubricant additives
• Commissioned in 1999
• Located on the Jurong Island

chemical hub

Energy Efficiency: Steam Trap Monitoring

• Challenge
• Failure cause steam losses
• Inefficient heat transfer, requiring more steam,

may lead to process upsets

• Water hammer damage piping and flanges
• Yearly steam trap surveys are too infrequent
• Solution
• On-premises steam trap monitoring sensors

and analytics

• Result:
• Reduced steam losses

Energy Efficiency: Energy Management Analytics

• Challenge
• Lack of Energy Monitoring Dashboard

may lead to inefficiency and high energy costs

• Solution
• Steam consumption monitoring at

unit level

• Analytics from historian
• Result
• Ability to pinpoint overconsumption

to troubleshoot effectively

Safety: Access Control and Rescue Locating

• Challenge
• Manual paper-based sign-in / sign-out is disruptive

to operators

• Physical fencing would hinder evacuation
• People may stray outside assigned areas
• Locating man-down requires large search party
• Hard to manage contractors during high risk

activities such as start-up and shut-down

• Solution
• Real Time Locating System (RTLS)
• Result
• Faster locating of missing persons
• Smaller search party
• Effective geofencing
• Good control of plant access
• Increased contractor productivity

Reliability: Pump and Compressor Monitoring

• Challenge:
• Critical equipment vibration causes

production downtime

• Manual vibration data is time

consuming

• Solution
• Vibration sensors
• Vibration analytics software
• Result
• Ability to predict failures
• Increased reliability
• Reduced maintenance cost

Integrity: Corrosion Monitoring

• Challenge:
• Corrosion may lead to loss of

containment

• Solution:
• Corrosion sensors
• Predictive analytics
• Result:
• Scheduling of pipe section

replacement

• Help avoid loss of containment

Productivity: Worker Mobility

• Challenge
• Incomplete and sometimes inaccurate

data capture using paper-based

• perations surveillance
• Access to procedures, P&IDs, and

maintenance request (SAP ERP) is only available in the control room

• Most process and equipment data only in

the DCS (control room)

• Solution
• Tablets using Wi-Fi infrastructure to

access work orders, documents, and more

• Result
• Increased productivity

Summary

• Improved energy efficiency
• Plant is a safer place to work
• Increased reliability
• Greater integrity
• Improved productivity
