Eight Iranian contractors have made six development phases of South Pars gas field, which are all oil megaprojects, operational. That comes against the backdrop of tough sanctions against Iran's oil sector in the past years. International companies had pulled out of Iran and the country faced numerous problems in operating oil projects. Rarely could one imagine that Iran would be able to implement its major oil and gas projects without reliance on foreign companies. But under the aegis of the Iranian Ministry of Petroleum, Iranian companies have managed to implement South Pars development projects one after another and reach Qatar in gas recovery from the field shared by the two countries. As the Ministry of Petroleum had promised, three more projects including South Pars development phases 17, 18, 19, 20 and 21 would come on-stream before the administration of President Hassan Rouhani bows out later this year. In total, 11 development phases of South Pars would have become operational under Bijan Zangeneh as minister of petroleum.
Industrial Projects Management of Iran (IPMI) affiliated with Iran's Industrial Development and Renovation Organization (IDRO), Oil Industries Engineering and Construction Company (OIEC), Iranian Offshore Engineering and Construction Company (IOEC), Petropars, Petropars Iran, Iran Shipbuilding and Offshore Industries Complex Company (ISOICO), National Iranian Drilling Company (NIDC) and Energy Dana are eight Iranian companies tasked with operating three South Pars projects which are close to coming online. The bulk of their activities are summarized as follows:
In development phases 17&18 of South Pars, a consortium of OIEC and IDRO has been in charge of onshore activities, while IOEC and ISOICO have teamed up for offshore operations. NIDC and Energy Dana have been in charge of drilling operations. The entire project has been steered by IDRO. It was the first time that all construction operations in South Pars were handled by Iranian companies. Afterwards, Iranian contractors were emboldened to handle the construction of refineries.
On behalf of IDRO, IPMI was in charge of non-processing activities like receiving sour gas, transferring sweet gas to national grid, building utilities, storage tanks and sulfur recovery units.
OIEC was tasked with operating processing units including four rows of gas treatment, gas sweetening under Worly Parsons license, dehydration, ethane recovery, gas liquid separation, propane refrigeration (using refrigerating compressors), as well as propane and butane sweetening.
IOEC built two main platforms at Phases 17&18, weighing 7,050 tons at Khorramshahr Yard, carried out onshore pipelaying on 10 kilometers and offshore pipelaying on 214 kilometers and connected onshore pipelines to the treatment facility. ISOICO handled the construction of two satellite platforms - 17B and 18B - each weighing 2,300 tons in Bandar Abbas Yard. This company managed to hit the record for installation and gas production in South Pars. This record was already set by Norway's Statoil at 6 months plus 15 days. But Platform 18B came on-line in 62 days by ISOICO engineers. ISOICO had earlier operated the platform of Phase 16 during a period of five months plus 10 days.
NIDC spudded 22 wells in platforms 17A and 18A. These drilling operations started in 2010 by two drilling rigs. The operations ended in April 2014. The result was an overall drilling of 93,490 meters. This project created 400 direct jobs.
Dana Energy Co.
Dana Energy was in charge of drilling 22 wells in the platforms 17B and 18B with the help of three drilling rigs. The operations started in March 2013 and ended in June 2016. Overall, 91,000 meters was drilled. A total of 400 jobs were created directly and more than two million hours of work was registered.
Phase 19 development of South Pars was awarded to consortium of Petropars, IOEC and Petropars Iran. The project is led by Petropars.
Petropars was tasked with drilling 21 wells and building a refinery on 216 ha of land. Supplying 52% of equipment used in drilling and 70% of equipment used in the refinery was handled by Iranian manufacturing companies. Among records set in Phase 19, the operation of three rows of treatment facilities within six months and launching a treatment facility with the help of domestic manpower with the presence of foreign companies.
IOEC was tasked with three offshore platforms, 480 kilometers of pipelines (diameters measuring 4 inches, 32 inches and 18 inches) and building a single-point mooring. Hookup operations (following the installation of Platform 19C) started in nine days, Platform 19A was installed in three hours, Platform 19A was launched and gas was transmitted to national grid in 70 days, while the knowhow for SPM construction was mastered.
Phases 20&21 of South Pars were developed by OIEC and IOEC. The project was led by OIEC.
Drilling 22 wells with an overall 88,000 meters of drilling without accident and construction of refineries in phases 20&21 were up to OIEC. A total of 13 contractors were active in the refinery sector. Installation of 44,000 tons of structures, laying 6,400 kilometers of cables (equal the distance between Iran and Germany), pouring 307,000 cubic meters of concrete and using 37,000 tons of equipment, building fully Iranian control room and indigenization of equipment were among measures by this company in the development of Phases 20&21.
IOEC was tasked with the construction of two gas platforms, each weighing 2,700 tons, laying 210 kilometers of pipeline (measuring 32 inches in diameter) and 210 kilometers of pipeline (measuring 4 inches in diameter). In total, 16,000 tons of structures and equipment were used in this project. Direct job creation for 600 people in Khorramshahr Yard, benefiting from Iranian engineers' expertise in designing, engineering, commodity supply, platform construction, transfer, installation and launch, building a system to control the platform, setting a 60-day record for platform construction, four-month record for laying 200 kilometers of offshore pipeline with an IOEC-owned vessel are among measures of this company in the SP 20 and 21 megaprojects.
