Topsides of 13B main platform and 13D satellite platform of the South Pars Gas Field were loaded at Iran Marine Industrial Company (also known as SADRA) in the northwest of Persian Gulf.
Payam Motamed, operator of Phase 13 of the huge gas field, said on Thursday that the structures were loaded on FLB 124 barge off the Persian Gulf coast, IRIB News Agency reported.
According to Motamed, local engineers carried out the designing and construction of the platforms. Domestic manufacturers supplied most of the goods and equipment required to build the two huge structures, weighing 2,200 tons.
Each of the platforms, when operational, would extract 14 million cubic meters of natural gas from the joint offshore field. Iran shares South Pars gas field with Qatar.
Installation of both maritime structures is expected to end by November and gas extraction to start in the winter.
With the installation of the two platforms, extraction capacity from Phase 13 will reach 28 million cubic meters per day.
Earlier this month, the second major pipeline of South Pars Gas Field's Phase 13 was connected to onshore facilities.
Phase 13 consists of offshore infrastructure, including 38 wells, four platforms and four pipelines stretching over 90km off the Persian Gulf coast, as well as onshore facilities, including four gas refining units.
Once all four units are operational, the phase will extract 56 million cubic meters of natural gas per day. It is planned to extract 2,900 tons of liquefied petroleum gas, 2,750 tons of ethane, 75,000 barrels of ultra light crude, also known as condensate, and 400 tons of sulfur.
South Pars, known as North Dome in Qatar, is being developed in 24 phases.
Phase 13 is in line with plans to raise natural gas output to 1.1 billion cubic meters per day by 2021.
National gas production capacity stands over 800 million cubic meters a day. Supplies from South Pars account for nearly two-thirds of total gas supply.
