The operation was carried out on the 30 inch diameter, which stretches 2.6 km from Burton Point AGI to Connah’s Quay Power Station.
The scope of work included pipeline preparation, cleaning, geometry and corrosion inspections, global positioning system (GPS) mapping and cathodic protection/coating surveys.
TDW used a number of its high resolution inspection tools to inspect the pipeline. They include the deformation tool for geometric anomaly inspection, the gas magnetic flux leakage inspection tool for corrosion inspection, and the XYZ inertial measurement unit for GPS pipeline mapping.
TDW is now preparing to carry out a similar in-line inspection on a 10 inch diameter pipeline attached to E.ON’s Killingholme Power Station in Lincolnshire, England.
