T.D. Williamson, Inc. (TDW) recently launched two new diameters of its Multiple Dataset (MDS) inline inspection technology, 6- and 30-inch. The platforms include Deformation (DEF), Axial magnetic flux leakage (MFL), SpirALL® MFL (SMFL), Low Field MFL (LFM) and XYZ Mapping.

Operators of smaller diameter gathering and midstream lines can now achieve comprehensive integrity assessment in a single run with TDW’s new 6-inch MDS platform. The compact tool weighs only 146 pounds (66 kg) and is a mere 73-inches (1.85 m) in length. Counting the 6-inch inspection runs previously executed in 2013, and those currently scheduled, 14 segments and almost 600 miles (966 km) of pipeline will be inspected in the diameter’s first months on the market.

On the other end of the spectrum, larger diameter transmission operators are also benefiting from TDW’s new 30-inch MDS technology. In late October 2013, TDW completed a successful inspection of a 30-inch pipeline, 43 miles (69 km) in length. The operator was pleased with the process and results, and scheduled several additional segments for inspection in the coming weeks.
