Saudi Aramco is preparing to receive bids from contractors for three engineering, procurement and construction (EPC) packages for a pipeline network at its $14-$15bn Marjan field development.

The three packages will see the installation of pipelines from the main gas oil separation plant (GOSP) at Tanajib to the oil-processing facilities at Jubail, Ras Tanura and Tanajib.

Each of the packages is estimated to be worth $200m, and the final bid submission deadline for the pipeline works is 31 December, a source told MEED.

There is an overlap between the contractors bidding for the pipeline works, as per the source, with some of the pre-qualified firms being:

• Saipem (Italy)
• Tecnicas Reunidas (Spain)
• Punj Lloyd (India)
• China Petroleum Pipeline Engineering Corporation (China)
• Arkad Engineering & Construction (Saudi Arabia)
• Nasser S Al Hajri Corporation (Saudi Arabia)
• Sinopec (China)

Aramco has so far tendered 20 separate packages as part of its Marjan crude increment programme, which is designed to raise the oil and gas production and processing capacity by 300,000 barrels a day (b/d) through to 2024-25, from a current base of 500,000 b/d.
