Saudi Aramco is preparing to tender a gas oil separation plant (Gosp) for its Marjan field development project, reports Middle East Business Intelligence magazine. Under current plans the engineering, procurement and construction (EPC) contract is expected to be worth $4 -5bn. The project is about Engineering, procurement and construction (EPC) contract to build a Gas Oil Separation Plant (GOSP) with capacity of 300,000 barrels per day (bpd) in Saudi Arabia. The plant is located at Tanjib, 260 kilometers north of Dhahran. This package forms a part of an overall Marjan Offshore Oilfield & Onshore Facility Expansion project. The contract include the replacement of the decks of two existing tie-in platforms, as well as the removal and salvage of existing gas turbine generators, and the installation of two new 115kV subsea power and communication cables. After processing the residual heavy crude will be blended with the Safaniya oil and shipped to the refinery at Ras Tanura. The Marjan GOSP-4 will be intended to deal with 475,000 barrels for every day of oil, 813,000 bpd of fluid and right around 750 million cubic feet for each day of gas. The proposed venture will be found under 10 kilometers from the current Marjan GOSP-2 and GOSP-3 offices. The GOSP-4 bundle incorporates different offices and stages, including another convenience stage, gas pressure stage, tie-in stage and so forth. It will likewise incorporate one 36-inch subsea oil trunk line totalling 100 km, and two subsea links to associate the seaward offices to the Marjan field's current coastal offices. Two new 115kV subsea power and correspondence links to the Marjan field's current coastal offices ?about 200 kilometers? The agreement would incorporate the substitution of the decks of two existing tie?in stages, just as the expulsion and rescue of existing gas turbine generators. The US engineering company is currently working on the front end engineering design (feed). An EPC tender is expected to be announced in Q3 of 2018. The project is expected to complete by 2022.
