Shaw Pipeline Services was established in 1990 to deliver AUT services for the pipeline industry and is now regarded as the leading company in its field.

Led by a carefully planned growth strategy, Shaw Pipeline Services has successfully expanded its equipment fleet to serve the global market.

In 1997 the division implemented its global expansion strategy with the acquisition of the UK-based QED. This enabled the division to strengthen its presence in the Eastern Hemisphere The same year Shaw Pipeline Services introduced AUT into Saudi Arabia on the Shaybah project. In 1998 its AUT technology was introduced to Latin America on the Gasbol project, to the North Sea on the Ketch Corvette projects, and to the Far East on the West Natuna project. In 1999 its AUT technology was introduced to the US land sector on the Alliance project.

As the new millennium rolled in, Shaw Pipeline Services further expanded its service capabilities through the acquisition of the leading US pipeline inspection company, Edwards Pipeline Services. Growth continues to be a central strategy as we focus on the dynamic needs of our customers in a technically challenging environment.
