Saudi Aramco has received bids from contractors for the main gas compression packages of the third expansion project of the Master Gas System network (MGS-3) in Saudi Arabia.

The MGS-3 project has two main engineering, procurement and construction (EPC) packages that cover upgrading existing gas compression systems and installing new gas compressors.

Contractors submitted technical bids and related In-Kingdom Total Value Add (IKTVA) credentials for the two main gas compression packages by 4 January.

Commercial bids for the gas compression packages were submitted by 7 January, according to sources.

MEED has reported that Aramco has extended the bid submission deadline for the two packages several times. 

Aramco has divided the EPC work on the MGS-3 project into 17 packages, MEED previously reported. Aside from the two gas compression packages, the 15 other packages relate to laying gas transport pipelines across various locations in the kingdom.

Aramco received technical bids for the 15 pipeline packages of the MGS-3 project during the third and fourth weeks of August.

Contractors submitted commercial bids for 15 pipeline packages of the MGS-III project during the last two weeks of September, MEED previously reported.

The original Master Gas System (MGS) was built in the 1970s and commissioned in 1982. Since then, Aramco has been supplying natural gas to its customers across Saudi Arabia via the network, mainly channelling associated gas from Ghawar and other oil fields.

Over the past decade, amid rising gas demand from Saudi Arabia’s industrial and household sectors, Aramco has undertaken projects to increase its non-associated gas production. It launched the second expansion phase of the MGS (MGS-2) in 2015.

Local contractor Arkad Engineering & Construction won the three main pipeline packages of MGS-2, worth an estimated $1.3bn, in early 2016.

EPC works were completed in 2021, increasing the MGS’s gas handling and transport capacity from 8.4 billion cubic feet a day (cf/d) to 12.5 billion cf/d.

MGS-3 EPC tendering phase

Aramco completed the solicitation of interest (SoI) process with contractors for the two gas compression packages of the MGS-3 project in December. SoIs for the pipeline packages were issued by Aramco in March last year, with contractors expressing interest within days.
