Selected contractors have until 13 August to submit technical proposals for the project, which covers the installation, testing and pre-commissioning of a pipeline between the Hubara compressor station to the Marmul oil field, and another pipeline between Harweel and Marmul.

The work involves the construction of a new 18-inch-diameter pipeline by converting the existing 84-kilometre oil pipeline between Marmul and the Nimr field and adding a new 75-kilometre section between Nimr and Hubara. The contract also calls for the installation of a 16-inch-diameter gas export pipeline between Harweel and Marmul.

Other facilities covered in the contract include two block valve stations between Harbura and the Amal field, receivers and launchers, tie-ins, and pressure reduction stations. The client says it will procure the line pipe, valves, flanges and couplings, with any other equipment supplied by the winning bidder.

Under the proposed bidding schedule, the percentage breakdown of prices will be submitted on 17 September once technical evaluation is completed. The online bidding date has been set for 24 September, with an award due by the end of 2008.
