Dubai Electricity and Water Authority has broken the world record in major inspection outages by re-engineering the Gas Turbine SGT-4000F overhaul process at the Jebel Ali Power and Desalination Complex. DEWA succeeded the completion of its major inspection outage within 11 working days compared to 30 working days previously. This allows a 63% reduction in outage duration, leading to increased availability of its gas turbines.

These gas turbines, along with the steam turbines in the same train, provide 63.2% of DEWA’s gas plant power generation capacity, and 55% of the total thermal energy needed to produce desalinated water that DEWA provides to Dubai.

The project’s objectives were to strengthen and highlight Dubai's position as a leader in technological transformation. There are a total of 461 similar units worldwide, with 46 in the UAE. The lessons learned from DEWA’s achievement helped global users to use these turbines as a benchmark to improve their operating costs and availability of their services, and improve their environmental footprint.

Since the project’s success, the major inspection outage period over the next 12 years is expected to result in an increase in the availability of high-efficiency units and use by 756 days. In addition, DEWA managed to reduce carbon dioxide emissions by 394,632 tonnes in a year, equivalent to 18.13 million trees.
