Siemens today announced it has completed extensive service works of the gas turbines at Jebel Ali K-station in a record time of only 29 working days, a notable accomplishment for a project of this scale. The power plant is located in Dubai and owned by Dubai Electricity and Water Authority (DEWA) and in operation since 2002.
The outage featured the application of the “rotor-swap”; a pioneering concept that has been developed by DEWA to utilize a spare rotor and other critical parts, stored at the plant’s site, to maximize each unit’s availability and reduce idle time while waiting for the completion of rotor assembly work. DEWA has implemented this concept for the first time in the Middle East in January 2015. To-date, the rotor-swap concept has been implemented for eight times across DEWA’s different power plants, which resulted in increasing the availability of the power generation assets by up to 64 days. This reflects DEWA’s commitment to the efficiency and reliability of the power sector in the UAE.
Under terms of the 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 about 15 years. The upgrades also increased power output by 62.6 megawatts (MW) and improved power plant efficiency by about 0.5 percent.
“The new project is built on over 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,” said Nasser Lootah, Executive Vice President of DEWA. “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 over 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 benchmark in the global power service industry.
"DEWA puts a great importance on the availability and sustainability of power for Dubai’s population, which results in their continuous commitment to innovative ideas and proactive approach for accomplishing the best results,” said Gianluigi Di Giovanni, Senior Executive Vice President of Siemens Power Generation Services in the Middle East. “This record-breaking project was only possible with the outstanding collaboration and planning between DEWA and Siemens, which provided innovative solutions and technical expertise. This project also reflects our commitment to bringing the company’s latest and most-advanced technologies to the UAE to help boost the efficiency and sustainability of its energy sector.”
Recently, Siemens and Dubai Electricity and Water Authority (DEWA) have signed an agreement to collaborate on an advanced data-driven project. The project 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 of its power generation assets. Siemens and DEWA are working together to identify ways to improve thermal efficiency, provide cost-effective solutions for performance optimization, manage costs and reduce fuel consumption and emissions.
