Turnkey ILI of a gas storage pipeline

Pipeline Description:

The pipeline is a 10” field pipeline connecting an operational site to a cavern at a gas storage facility in northern Germany. It had never been inspected before, featured a heavy wall thickness, and was temporarily decommissioned for inspection.

Why is it challenging?

No Prior Data: The pipeline had never been inspected before, leaving no historical data for reference. Pipeline Characteristics: The heavy wall thickness required specialized ultrasonic tools for accurate measurements. Logistical Complexity: Temporary decommissioning and operational takeover added to the complexity of the project. Tight Schedule: Completing such a comprehensive project within one working week demanded precision and efficiency.

Target of the inspection:

The primary goal was to assess the pipeline’s integrity and operational safety, identify potential metal loss, and establish a reliable baseline condition. Additionally, precise geographic mapping of welds and anomalies was targeted for better future monitoring and maintenance planning.
