Maintenance Management

The personal care of a home doctor who knows you well. The advanced diagnostic technologies of a modern medical center. What if we say you can have the best of both worlds?
Our service experts make the equivalent of "house calls" to your plant, getting to know the inner works of your operations. At the same time, our remote monitoring and on-line diagnostics technologies empower them to zero in on the exact areas where proactive maintenance can make the most difference. The upshot is you receive more accurate and effective maintenance best suited for your plant while avoiding unnecessary fixes for problems that do not actually exist.

Shutdown Maintenance

Condition Based Maintenance (CBM)

The purpose of shutdown maintenance is to preserve the soundness of systems at optimal cost. A customer's system conditions are evaluated, and the most suitable program is proposed. With the customer's approval, our engineers proceed to carry out the maintenance.

Diagnosis

The tools of CBM

Diagnosis Yokogawa has the diagnostic technology that can predict what usually cannot be seen. With our tools and inspection technologies, we can ascertain and show to customers the current condition of their system, and propose optimal maintenance measures.

Environment Improvement

Condition remedy

An optimal improvement measure based on diagnostic results is proposed.

-Environment improvement
   This could include measures such as the revamping of the control room or the
   installation of equipment

-Recovery
   Cleaning of printed circuit boards

-Renewal
   Coating of printed circuit boards

Periodic Maintenance

The tools of PM

Spotting potential problems before they occur and implementing preventive maintenance

-On-site periodic maintenance
   A Yokogawa engineer periodically patrols the customer's site to inspect its operational
   status.

-Online periodic maintenance
   A remote surveillance system regularly collects various types of system data, based on
   which improvement proposals are submitted.
