Why Commissioning Phase Is the Most Overlooked Risk in Methane Monitoring Systems

Methane monitoring commissioning plays a critical role in determining how effectively emissions are detected, measured, and understood over the lifecycle of a system.

Overview

Methane monitoring is often evaluated once a system is operational.

Once the asset is running.

Once production is stable.

Once reporting begins.

But in practice, many of the issues that affect long-term monitoring performance are introduced much earlier.

During commissioning.

The assumption: monitoring starts after operations

In many projects, methane monitoring is treated as something that becomes relevant once the system is fully operational.

  • monitoring systems being validated late
  • data workflows being configured post-handover
  • limited testing under real operating conditions

This creates a gap.

Because by the time monitoring begins, the system has already inherited its limitations.

What actually happens during commissioning

Commissioning is where systems are:

  • installed
  • tested
  • calibrated
  • handed over

But in methane monitoring, several critical factors are often not fully addressed:

  • sensor placement relative to real emission points
  • system response under variable load conditions
  • alignment between monitoring outputs and reporting requirements
  • integration with operational data

At this stage, systems may appear functional.

But not necessarily fit for long-term monitoring objectives.

Why this creates long-term issues

  • detection coverage may be incomplete
  • emissions behavior may not be captured accurately
  • data may not align with operational conditions
  • reporting inconsistencies may emerge later

These issues are difficult to correct once the system is live.

The architecture is already in place.

The hidden problem: testing without context

  • system functionality
  • basic detection capability
  • equipment performance

But what is often missing is:

  • testing under real emission scenarios
  • time-based validation
  • correlation with operational variability

Systems pass tests — but fail in operation.

Why intermittent emissions make this worse

  • start-up and shutdown conditions
  • pressure fluctuations
  • equipment behavior
  • operational changes

If commissioning does not account for this:

  • monitoring systems may miss intermittent emissions
  • detection reliability may vary
  • emissions may be underreported

The role of thermography and LDAR during commissioning

Thermography

  • identify abnormal conditions
  • support system checks

LDAR

  • introduced later
  • early-stage leaks may not be captured
  • baseline emissions not fully understood

The missing layer: system validation, not just testing

Operators need to assess:

  • how monitoring performs over time
  • how it responds to operational changes
  • how data integrates across systems
  • whether emissions behavior can be explained

This becomes:

“Is the system capable of explaining emissions over time?”

Why this matters in the GCC

  • infrastructure is scaling rapidly
  • LNG and gas projects are expanding
  • emissions reporting expectations are increasing

If commissioning is weak:

Everything built on top of it is affected.

FAQ

Why is commissioning critical?

Because it defines long-term monitoring performance.

What is commonly missed?

Validation under real conditions.

Can issues be fixed later?

Some, but many are difficult to correct.

What is the key requirement?

System-level validation.

Bottom line

Methane monitoring systems do not fail suddenly.

They fail gradually.

And often, the root cause is commissioning.

If the system is not validated early, it cannot explain emissions later.
