UAE: Dubai Electricity and Water Authority, DEWA, 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 in the completion of its major inspection outage within 11 working days compared to 30 working days previously.
This allows a 63 per cent 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 per cent of DEWA’s gas plant power generation capacity, and 55 per cent of the total thermal energy needed to produce desalinated water that DEWA provides to Dubai,” said DEWA managing director and chief executive officer Saeed Mohammed Al Tayer.
A 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.
DEWA has also managed to reduce carbon dioxide emissions by 394,632 tonnes in a year, equivalent to 18.13 million trees.
