Under the terms of the lump-sum engineering, procurement and construction contract, Dodsal will install more than 220 kilometres of polyethylene-coated pipe from the Asab, Bu Hasa and Bab onshore fields to its treatment plants at Ruwais on the coast.
The existing 25-year-old network will be demolished once the new pipelines are commissioned.
Dodsal was frontrunner following the submission of bids in the summer, beating off competition from a number of other local and international contractors (MEED 19:10:07).
The consultant on the scheme is Veco from the US.
Gasco operates major gas plants in Abu Dhabi, including a 3,500 million cubic feet a day facility at Habshan.
