NDT Global has received a multi-million Euro contract from Statoil to develop an in-line inspection tool for the 707-km Åsgard Transport The pipeline would be approximately 400-km in length, with a 200-km onshore section between Rudan to Mobarak Mount in the southern gas pipeline. In close collaboration with Statoil, NDT Global is developing a suitable in-line inspection (ILI) tool for the Åsgard Transport gas Hormozgan province in Iran, and a 200-km offshore section onwards to Sohar Port in Oman. pipeline. The company will also supply the in-line inspection tool to perform the corresponding survey. Local news sources have reported that KOGAS could sign a memorandum of understanding or a framework agreement for the US$1.5 billion The Åsgard gas pipeline is part of the Norwegian gas infrastructure system, owned by the joint venture named Gassled.
