How can you maintain pipeline instrumentation during shutdowns?

1 Identify the critical instruments

Not all instruments are equally important for the pipeline performance and safety. Some instruments may be more critical than others, depending on the location, function, and impact of the instrument on the pipeline system. Therefore, you should identify the critical instruments that require more attention and care during shutdowns. For example, you may prioritize the instruments that are involved in emergency shutdown systems, leak detection systems, or flow metering systems.

2 Isolate and protect the instruments

Once you have identified the critical instruments, you should isolate and protect them from the external environment and potential hazards during shutdowns. For example, you may use isolation valves, blinds, or plugs to prevent the ingress of moisture, dirt, or foreign materials into the instrument lines or tubes. You may also use protective covers, coatings, or wraps to shield the instruments from physical damage, corrosion, or UV radiation.

5 Replace or repair the faulty instruments

If you find any faulty instruments during the inspections and tests, you should replace or repair them as soon as possible to avoid any complications or delays when the pipeline resumes operation. For example, you may replace the instruments that are beyond repair or calibration, such as damaged sensors, transmitters, or gauges. You may also repair the instruments that can be fixed or adjusted, such as loose connections, worn seals, or misaligned components.

6 Follow the standard procedures and guidelines

Finally, you should follow the standard procedures and guidelines for maintaining pipeline instrumentation during shutdowns to ensure consistency, quality, and compliance. For example, you should follow the manufacturer's recommendations, industry standards, or company policies for the maintenance frequency, methods, and documentation. You should also follow the safety rules, regulations, and best practices for the maintenance personnel, equipment, and environment.
