Guwahati: Indradhanush Gas Grid Limited (IGGL) has completed a major milestone in the North East Gas Grid (NEGG) project by constructing the challenging 24-inch diameter hydrocarbon pipeline beneath the Brahmaputra by Horizontal Direction Drilling (HDD) method. This connects Jorhat and Majuli.
The longest underwater hydrocarbon pipeline in Asia has given the Assam government’s efforts to make natural gas accessible in the North East a significant boost.
IGGL CEO Ajit Kumar Thakur announced on Saturday that the herculean work of installing the 24-inch diameter pipeline using the HDD technique was finished on Friday.
IGGL is implementing the 1,656-km NEGG natural gas pipeline project at a cost of Rs 9,265 crore. The pipeline spans the major water channel of the Brahmaputra for 4,080 m.
The Brahmaputra River HDD crossing spans a total of 5,780 m, considering all major and smaller water channels. The pipeline was installed in three distinct portions that are 1,000 m, 4,080 m and 700 m in length, with the first and third parts already finished.
“With the completion of the Brahmaputra HDD, IGGL has achieved more than 71% physical progress of the NEGG project and we will be able to complete the Guwahati-Numaligarh section by February 2024. I’m extremely proud of my team, which has worked tirelessly to achieve this milestone overcoming challenges of monsoon rain and floods in Assam,” said Thakur.
He also expressed his gratitude to the Assam government for its assistance.
