NDT Global: ILI contract on Åsgard Transport gas pipeline

NDT Global, a leading supplier of ultrasonic pipeline inspection and integrity services, has announced that it has received a multi-million euro contract, on behalf of Gassco, from Statoil, the leading Norwegian gas and oil enterprise.

In close collaboration with Statoil, NDT Global is developing a suitable inline inspection (ILI) tool for the Åsgard Transport gas pipeline. The company will also supply the ILI tool to perform the corresponding survey.

The contract

The high profile project contract was won despite strong competition. By offering an innovative inspection solution and sound engineering plan, NDT Global received this high profile project order from Statoil. The offered inspection tool includes the latest in-house developments of combined inspection technologies.

The project

The Åsgard transport pipeline starts at the semi-submersible Åsgard B platform in the Norwegian Sea, and terminates at the Kårstø processing plant in southwest Norway. It has been in operation since October 2000.

The project presents a number of unique challenges: in addition to the line’s sizeable 707 km length, the wall thickness of the pipeline is exceptionally high – up to 55 mm. Under these conditions, ILI tools must be exceptionally durable, and still able to accurately detect any flaws that could compromise the pipeline’s integrity. Moreover, tools need to negotiate a sizeable, 14 in. change in diameter in the 28 - 42 in. pipeline – all the while maintaining excellent operability, high data quality and accuracy.

Additional information

NDT Global has worked with Statoil in the scope of a Framework Agreement since 2006. The current purchase order was received in 2015 and ILI is scheduled to commence in 2017.
