Isolations
Interlocks and Overrides, Critical Equipment and Barrier Management
RAP’s Isolations solution offers visibility of current, future and historical permitting workload and highlights “overload risk” and provides additional dashboarding and reporting functionality specific to these in order to ensure operational risk management for process safety.
System | Features
Through the years Yokogawa RAP have enabled our customers to monitor critical aspects of their plant. These could be the monitoring of:
- Interlocks and Overrides (IOR’s)
- Management of critical valve downtime allowance such as for Pressure Relief testing (PR testing)
- Offline time for partial stroke work with emergency Shutdown Valves (EDS’s)
- Bypass line routing whilst the main line is closed for maintenance
Aside from monitoring the timeline of removed devices, we have also been asked to monitor:
- Downtime on critical alarms
- Monitoring line blind (or spade) insertion
- Air gap presence
The above examples have one thing in common, they are a change to the normal operating process and involve either the removal of or addition of a safety barrier within the system.
The isolation module from Yokogawa RAP sets the procedure for carrying out safe isolations and by bringing together our critical asset monitoring capability the updated Isolations module allows our users to benefit from an easy to use system and approach to barrier management to manage and monitor priority process barriers in real time, no matter what type they are for the duration that they are in place and to make sure that users are aware if barriers are not back to normal state in line with planned timeframes.
Linking to the isolation system as well as to the existing permits, the newly updated Isolations system from Yokogawa RAP is yet another example of how we assure smarter, safer working for operational excellence.
