Recurring Inspection and functional checks of your valve interlocks and supporting safety systems
Understanding the status of you valve interlocks
Sofis valve interlocks are designed to be extremely robust. When operated correctly, Sofis interlocks last for more than 20 years. Still, interlocks sometimes do get broken, bypassed and removed, in particular by operators and maintenance engineers. Understanding the status of your interlocks and recording of failures is therefore of key importance. Knowing the cause of the malfunction allows you to adequate plan follow-up action and eventually reduce the number of defects.
Many Sofis customers participate in recurring inspection of their valve interlocks, as part of an annual asset integrity program. Inspections provide an in-depth understanding of the status of your valve interlocks all related safety systems. This allows you to manage your assets and efficiently plan maintenance activities, avoiding ad-hoc repair jobs.
During an inspection of your valve interlock systems, so called ‘hidden defects’ can be identified. These are critical safety risks that can lead to problematic situations that need to be addressed immediately and require an ad-hoc solution. This should be avoided at all times, especially in times where you can expect an increasing number of challenging situations, such as limited access to plants, decreased team capacity and budget limitations.
