Siemens has completed extensive service operations on gas turbines at Dubai’s Jebel Ali K-station ahead of schedule in a record time of only 29 working days.
Owned by Dubai Electricity and Water Authority (DEWA), the power plant has been in operation since 2002.
The outage featured a rotor-swap, a technique developed by DEWA to utilise a spare rotor, and other critical parts stored at the project site, to optimise the availability of each unit and reduce idle time while waiting for the completion of rotor assembly work.
Under the deal, Siemens was responsible for delivering supervisory services for three of Jebel Ali K-station's turbines, enabling further efficient and reliable operation of approximately 100,000 hours.
The upgrades have also helped increase the power plant’s energy output by 62.6MW and enhanced the facility’s efficiency by nearly 0.5%.
DEWA's executive vice-president Nasser Lootah said: “The new project is built on more than 30 years of trust and partnership with Siemens.
“We are very pleased to work with the company again and successfully complete services of Jebel Ali K-station's power assets so quickly, which allowed the plant to reduce the length of maintenance outage and return the turbines to service as early as possible.
“With this project, we will enhance the power output and the long-term availability of our power generation assets.”
All gas turbines need to be dismantled for maintenance services after a certain number of operating hours. Usually, this kind of an upgrade takes up to 45 working days, with the involvement of more than 100 personnel with varied technical expertise.
