A 3600-meter pipeline with a 24-inch diameter has been built by Ace Energy Infrastructure in Assam across the Subansiri River. Indradhanush Gas Grid Ltd. (IGGL), a joint venture of oil and gas firms including Indian Oil Corporation, Oil and Natural Gas Corporation, GAIL (India), Oil India, and Numaligarh Refinery, had this carried out.

MECON served as the Project Management Consultant (PMC). Part of this project was to extend the Pradhan Mantri Urja Ganga (National Natural Gas Grid) to the North Eastern states of India, said a press statement issued by the company.

The pipeline across the river was installed by utilising the intersect method of Horizontal Directional Drilling (HDD), positioning it among the largest pipeline installations worldwide using this technique.

“This endeavour stands among the largest HDD crossings undertaken globally. Our team of experts tackled several technical and logistical challenges with precision and dedication, resulting in the completion of this complex HDD crossing milestone,” Ravneet Singh, Director, Ace Energy Infrastructure said in the statement.
