T.D. Williamson SA (TDW), a global provider of pipeline services and equipment, reported the successful completion of an inline inspection (ILI) of a key jet fuel pipeline for the Belgian Pipeline Organisation (BPO). BPO is a military organization, responsible for the operational maintenance of the Central Europe Pipeline System (CEPS) on Belgian and Luxembourg territory.

The inspection of more than 130 kms of pipeline was carried out quickly and efficiently, enabling accurate identification of defects for targeted repair. To inspect the line, TDW used its Magnetic Flux Leakage (MFL) inspection tool, which uses magnets to saturate the pipeline. Sensors oriented within this magnetic field facilitate accurate detection and sizing of internal and external metal loss and other ferrous anomalies.

This project entailed inspection of a 10-inch line running from Schoten to Baasrode and Baasrode to Gent, and a 12-inch line running from Nazareth to Desteldonk. The inspection contracts were put to public tender and awarded to TDW in 2009 and 2010. TDW has been supplying pigging products, such as closures, pigs and pig passage indicators to BPO for many years, but this was the first time that TDW carried out inline inspection services using MFL technology for this client, and, in fact, in Belgium.

Latest MFL technology provides quick results

The MFL tool deployed by TDW in the BPO line uses the latest “floating magnet” technology. Each magnetizer “floats” individually so that magnetic forces are consistent whether in a thick or thin wall pipe, or a tight bend. By reducing tool drag, floating magnetizers enable more consistent velocities, which in turn facilitates more accurate inspection.

Ann Mariën, TDW Pipeline Integrity Sales Manager – Benelux and project manager for the BPO inspection, is very proud of the efficient and professional manner in which the work was carried out. “As this was the first time we had provided inspection services using MFL technology to BPO, we were especially keen to show them the advantages of TDW’s technology and management capability, and it was well received by the client,” she said.
