The Najybia Power Plant Project, located near Basrah, is part of a master plan developed and implemented by the Republic of Iraq’s Ministry of Electricity, to increase the power generation capacity in order to meet the country’s rapid growth in demand, following 25 years of war and lack of investment.
The project comprised engineering, procurement, construction, commissioning and start-up, for a 4 x 125 MW Power Generation Plant, to operate in simple cycle mode of operation with three types of fuel, Heavy Fuel Oil, Natural Gas and Light Distillate Oil, complete with all Balance of Plant systems, to support the safe and efficient operation of Combustion Turbine Generators units.
4×125 Najybia Gas Turbine Power Plant
Scope of Work
|Structural Steel||1,600 tons|
|A/G Piping||1,600 tons|
|Mech. Equipment||9,400 tons|
|Insulation & Paint||70,000 m²|
The Najybia power plant is expected to address the growing demand for power in the country and supply uninterrupted electricity to the people of Iraq. Due to lack of infrastructure and availability of reliable natural gas supply in the region, the Plant was designed to function on three different types of fuel to ensure continuity of operations. Storage and distribution systems for the two liquid fuels were carefully designed by ENKA with appropriate design margins and redundancy requirements.
Project site is located on the northern part of Basrah province on the banks of Shatt Al Arab River in a relatively high populated area. ENKA, while executing the work, successfully managed cultural relations with locals to avoid any clashes and maintained good relations with its neighbors.
Location and high temperatures during summer months created unique challenges for the project workforce peaked at 1,400 people. ENKA set up and maintained a safe and high quality job site inclusive of a good camp and provided high quality catering services. A robust safety and security approach was deployed and implemented by ENKA throughout the project duration to protect our workforce, our customer, as well as the environment and communities surrounding the Project.
Project site is located on the banks of Shatt Al Arab River and surrounded by water canals. Weak soil conditions necessitated significant amount of piling for foundations. As part of the EPC Contract, ENKA through its piling specialist subsidiary Kasktas have installed Ø800mm piles over 65,000 meters in total length.
ENKA SCOPE OF SERVICES
ENKA has self performed the basic engineering, detail engineering, procurement, construction, commissioning, start-up and performance testing scope for the project utilizing in-house resources on a lump sum turn-key basis.
