It follows IOEC winning a $380m contract late last year to construct the top part of the platforms on the offshore rigs, known as topsides.

Houston gas specialist Intec, which was recently acquired by Worley Parsons, previously won an engineering contract for three undersea pipelines totaling 440 kilometres for phase 12.

Earlier this year Petropars, a subsidiary of National Iranian Oil Company (NIOC) and the developer of South Pars, awarded a $284m engineering, procurement and construction (EPC) contract to the local Aras consortium for phase 12 (MEED 14:4:08).

NIOC expects to award two further EPC deals, to a local and foreign consortium respectively, in the next month.

Most of the gas produced from South Pars phase 12 will be used to feed NIOC’s planned liquefied natural gas (LNG) plant. However, part of the output will also be pumped into the domestic gas network for use in petrochemical projects and reinjection to maintain pressure on oil fields.
