ILI Inspections (Pigging, DGPS & MMI)

In-line inspection services for operating oil & gas pipelines — pigging operations, DGPS route mapping and MMI inspection runs that verify pipeline health, locate anomalies and give operators the data to run assets safely and efficiently.

Scope of Work

What this service covers.

Pigging Operations

Cleaning and gauging pig runs — launching, tracking and receiving with full run control and debris assessment.

ILI Tool Runs

Support and execution of intelligent pig campaigns, from line preparation to tool launch and receipt.

DGPS Mapping

Differential GPS survey of pipeline routes — accurate centreline coordinates for alignment sheets and GIS.

MMI Inspection

MMI survey runs identifying metal loss and geometry features on the pipeline.

Line Preparation

Cleaning trains, gauge runs and piggability verification before any inspection tool enters the line.

Reporting & Dig Support

Anomaly reporting, dig-sheet preparation and verification-dig support for repair planning.

Execution Method

How we deliver it.

Piggability Study

Line data, bends, valves and launcher/receiver readiness reviewed before the campaign.

Cleaning & Gauging

Progressive cleaning pig trains and gauge runs to prove the line safe for inspection tools.

Inspection Runs

DGPS / MMI / ILI tool runs with tracking, benchmark points and run verification.

Reporting

Verified anomaly lists, location data and dig sheets delivered to the operator.

Capability Snapshot

Materials, standards & testing.

HSE & quality, built in.

Every job runs under our HSE policy — hazard identification, EHS-trained crews, permits and stage-wise quality checks with full documentation.

Frequently Asked

Common questions.

Does the pipeline stay in service during inspection?

Yes — pigging and ILI campaigns run on operating pipelines. Product flow itself drives the tools; our teams manage launching, tracking and receiving without interrupting supply.

What if the line has never been pigged?

We begin with a piggability study and progressive cleaning-pig trains, proving the line with gauge plates before any costly inspection tool is committed.

What comes out of a DGPS survey?

Accurate centreline coordinates tied to your alignment sheets — the base data for GIS, depth-of-cover studies and future integrity digs.
