As well as overhauling the SGT5-4000F turbines at Sohar 2 and Barka 3 combined-cycle plants, Siemens also finalized major outage inspection services for the Ansaldo AE94.2 gas turbine at the Barka 2 plant.
All three power stations are operated by Suez-Tractebel Operation and Maintenance Oman LLC (ENGIE STOMO).
For the project, Siemens completed the works in a month in order to meet the rising power demand during the summer season.
Each outage involved more than 100 Siemens personnel.
Sohar 2 and Barka 3 are equipped with Siemens SGT5-4000F gas turbines and are located at the Sohar industrial park and Muscat respectively.
Siemens and its consortium partner GS E&C commissioned the two plants in 2012 in simple-cycle mode. Following steam turbine add-ons, both plants commenced commercial operation in combined-cycle configuration in 2013 with a total capacity of 1.5 GW.
Gianluigi Di Giovanni, senior vice-president of Siemens Power Generation Services in the Middle East, said that the region’s power generation challenges “are affordability, sustainability and efficiency”.à‚
