ADNOC Onshore is planning to undertake the construction of the Bab & North East Bab Tie-In facilities project in Abu Dhabi, the UAE.

The One Tie-In project at the Bab and North East Bab field developments is integral to Adnoc Onshore’s contribution to its parent company Adnoc Group’s objective of achieving an oil production capacity of 5 million barrels a day (b/d) by 2027 – a campaign known as Accelerated Integrated Programme 5.

The project aims is to establish infrastructure in accordance with the NEB P5 directive, focusing on Al Nouf, Rumaitha, and Shannayel facilities. Crude oil extracted from these locations is directed to MP-21 before being transported to export terminals at Jebel Dhanna and Fujairah. The Al Nouf (Dabb’iya) field is situated in a coastal or shallow marine area, while the Rumaitha/Shanayel structures are located onshore near the southwestern coast of Abu Dhabi. The project encompasses the development of both on-plot (CPP) piping systems and off-plot clusters, pipelines, and trunklines.

Adnoc Onshore has divided the scope of work on the Bab and North East Bab One Tie-In project into 18 packages, which are as follows:

The US$1200 million project includes the following:
