Challenges for Customers

After several decades of operating a plant, the operators are facing various age related problems like: inaccurate sensors, blocked impulse lines, spurious shutdowns (loss of air/electricity), seized valves, failed actuators, improper testing, system is not looped, is bypassed, tested or put back correctly after maintenance.

Also reflected in a different way, employees with years of experience are exiting the workforce through layoffs and retirements. In light of the recent recession, many end-user companies have even stepped up their efficiency programs. There is a scarcity in qualified workforce. At the same time, companies are tighter on capital and expenses continue to be tightly controlled. Government regulations dictate use of best industry practices adoption from industry standards like IEC 61508 and e.g. European directives like SEVESO III. All these practical issues are part of daily life in operating a plant.

Functional Safety Excellence

YOKOGAWA has developed their Safety Excellence services over the last decades, starting from their acquisition of GTI-IA in 1997.

Achieving plant performance through high availability and ensuring safe operations are the key goals for the owner’s technical authorities. Compliancy with the IEC61508, the Essential Standard for Functional Safety and the derived Sector-Application Standards like the IEC61511 for Process Industry, can only be achieved by continually monitoring the operational performance of the process safety of the plant and its individual components.

Safety excellence starts by determining the individual safety instrumented functions (SIF) of the plant. Collecting and storing continually all relevant data of each safety function in the plant operation data system. All information gathered will be used to evaluate functional safety of the plant and it will help the owner to confirm safe operation to the authorities, over process lifetime up to and including de-commissioning

Functional Safety Performance Monitoring  Services

Understanding the consequences involved with placing overrides within safety instrumented functions is a process requiring experienced personnel.

Working inadequate with maintenance overrides will result in potential dangerous situations. Implementation and control of process specific Management of Change supporting  reporting, authorisation, implementation, auditing assuring SIL for SIF over process lifetime.

For this Yokogawa offers a rich and unique package to pre-asses, authorise and optimise maintenance overrides.
