UK-based Mott MacDonald has been awarded a contract to carry out front-end engineering and design (feed) on a natural gas liquids (NGLs) extraction plant and pipeline in Oman, according to sources familiar with the project.

The project will extract NGLs from pipeline gas to feed Oman Petroleum and Petroleum Industries Company’s (Orpic) proposed $3.6bn Liwa Plastics petrochemicals complex in Sohar.

The scheme will be built at the Fahud oil and gas field in north central Oman and will be executed by Oman Gas Company (OGC) on behalf of Orpic, and will include a 300-kilometre pipeline to Sohar on the Gulf of Oman coast.

Products extracted by the plant will include ethane, liquid petroleum gas (LPG) and condensate, OGC said when announcing the project in October 2013.

In July, Orpic awarded five technology licences on Liwa Plastics worth a combined $80m. The complex will include a steam cracker and several downstream petrochemicals plants.
