Siemens recently completed extensive service works for the gas turbines at Jebel Ali K-station in a record time of 29 working days.

The power plant, located in Dubai and owned by Dubai Electricity and Water Authority (DEWA), has been in operation since 2002.

The outage featured the application of the rotor-swap; a new concept that has been developed by DEWA to utilise a spare rotor and other critical parts, stored at the plant’s site, to maximise each unit’s availability and reduce idle time while waiting for the completion of rotor assembly work.

DEWA implemented this concept for the first time in the Middle East in January 2015. To date, the rotor-swap concept has been implemented eight times across DEWA’s different power plants, resulting in increased availability of power generation assets by up to 64 days.

Under terms of the latest agreement, Siemens provided supervisory services for three of Jebel Ali K-station’s gas turbines to enable further efficient and reliable operation for approximately 100,000 hours – equivalent to approximately 15 years.

The upgrades also increased the facility's power output by 62.6MW, and improved power plant efficiency by approximately 0.5%.

Nasser Lootah, executive vice president of DEWA, said: “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.”

After a certain number of operating hours, all gas turbines need to be dismantled for maintenance services. Typically, an outage of this kind would take up to 45 working days to complete, involving more than 100 personnel with different areas of technical expertise. By implementing a newer outage concept, Siemens was able to perform the services within just 29 working days, setting a new standard in the global power service industry.

Siemens and DEWA recently signed an agreement to collaborate on an advanced data-driven project. The initiative is designed to help DEWA achieve its vision of becoming a sustainable, innovative world-class utility, and to ensure the highest levels of performance, efficiency, and reliability for its power generation assets.

The two organisations are working together to identify ways to improve thermal efficiency, provide cost-effective solutions for performance optimisation, manage costs, and reduce fuel consumption and emissions.
