Rehabilitation and Full Repowering of Ambarlı Fuel-Oil Power Plant Units 4 and 5 Conversion to Dual Fuel Combined Cycle Power Plant

Ambarlı Units 4 & 5 Rehabilitation Project involves the conversion of the existing 300MW Fuel-Oil fired boiler steam plant into 816MW Combined Cycle by addition of 2 new Gas Turbine Generators, 2 new Heat Recovery Steam Generators and rehabilitation & modification of existing Steam Turbines under new steam regime to achieve maximum performance. Thus, thermodynamic efficiency is increased from 36% to 54%, kwhour production costs are decreased, plant reliability is increased and excessive levels of atmospheric emissions are reduced significantly.

Ambarlı Project is a “Full Repowering by CCPP Conversion” Project that is a “first of its kind” Project in Türkiye and is equalled in magnitude and complexity by only a handful of worldwide examples.

Major Items in the Scope of Engineering, Procurement and Construction are;

• Dismantling of 2 existing fuel-oil firing boilers,
• Rehabilitation and modification of existing steam turbines, generators and auxiliaries,
• 2 new 282 MW Siemens SGT5-4000F gas turbines and generator sets,
• 2 new 357 ton/hour capacity, Vertical Type, three pressure level reheat Heat Recovery Steam Generators,
• New HP, IP, LP electric motor driven Boiler Feed Water Pumps,
• New 100% capacity HRSG Steam By-Pass (PRDS) Systems,
• New Condenser Cooling Seawater Circulation Pumps,
• New Seawater Treatment / Intake (TAPIS) Systems,
• Complete Retubing of existing condensers and Rehabilitation of seawater supply system,
• New 2km long NG supply pipe-line and RMS-A Station,
• New 380kV switchyard system, GT Side Transformers, MV & LV Switchgear
• I&C Systems and plant-wide DCS Integration
• Miscallenous Building Utilities.
• All other BOP Balance of Plant required conversion to a combined cycle power plant.

All the process/thermodynamic cycle optimization, conceptual, basic and detailed engineering, process equipment/system procurement, demolition, dismantling, construction, erection, installation, manufacturing, rehabilitation, modification, commissioning & start-up, performance testing and reliability run works, that pose special engineering and project management challenges beyond conventional needs of typical greenfield CCPPs, have been managed and implemented on a turn-key basis by Ekon-Prokon-Prokon JV, each of the party is a member of Prokon-Ekon Group of Companies, totally with local Turkish engineering and contracting teams, with no foreign entity consortium or joint venture partnership.
