EXCLUSIVE: Contractors prepare bids for Aramco’s Marjan onshore packages

16 January 2019
Contractors are preparing bids for six onshore packages with a combined value of about $2bn

Prequalified contractors are preparing to submit bids for the main engineering, procurement and construction (EPC) works for the onshore packages which are part of Saudi Aramco’s Marjan mega oil field development, estimated to be worth between $14bn-$15bn.

Aramco has set a deadline of 30 January for the contractors to submit bids for the onshore packages, according to a source.

It is understood that there are six onshore packages part of Aramco’s Marjan megaproject, which have an estimated combined value of $2bn.

A key onshore water injection package, worth $400m, calls for facilities to be built to transport water from well sites at the Marjan development to a new pump system at the gas oil separation plant (GOSP) in Tanajib, covering a distance of 70 kilometres.

Aramco is planning to construct a gas processing plant at Tanajib, which will be able to process 2.79 billon cubic feet of gas a day and 85 million barrels a day (b/d) of condensates from the Marjan field, as well as associated gas from Safaniya and Zuluf offshore fields.

The plant is expected to produce sales gas to Aramco’s Master Gas System and gas for offshore reinjection/gas lift and sulphur production. The plant will be designed to produce ethane, butane, propane, pentane and C7+ streams.

As part of this objective of the Marjan megaproject, four of the onshore packages relate to the construction of associated facilities for the proposed gas plant:

  • Package 9 covers provision of inlet, storage and compression facilities.
  • Package 10 relates to building systems for gas treatment and sulphur recovery.
  • Package 11 calls for facilities for natural gas-to-liquids (NGL) recovery and fractionation.
  • Package 12 pertains to the provision of utilities, flare and pipe rack facilities.

The four Marjan onshore packages mentioned above are understood to have a value of $375m each.

A sixth onshore scope – package 14, worth around $100m – consists of providing sulphur handling and propane loading facilities.

While Aramco is waiting to receive main contract bids by 30 January for the six packages, it is understood to have received bids for package 6, an onshore package related to building of general oil processing facilities at the Tanajib oil complex, for which the deadline was 6 January.

Aramco has tendered several works comprising the Marjan megaproject’s scope in close to 20 separate packages.

The packages are in different stages of the contract tendering process.

By way of this megaproject, Aramco is looking to raise the Marjan offshore oil and gas field’s overall production and processing capacity from the current 500,000 b/d by building supporting infrastructure and GOSPs.
