Project  :

Ambarlı Fuel-Oil Power Plant Units 4&5 By Conversions To Dual Fueled

Combined Cycle Plant And Rehabilition Project Istanbul, Turkey

Client : EÜAŞ General Directorate
Contract Date : 10.11.2008
Completion Date : 21.11.2013
Status : Main Contractor
Percentage Of Participation :

65 %

The project was carried out by EPP Joint Venture (EKON Industry Construction and Trade Inc. 65 % - PROKON Engineering and Consultancy Co. 30 % – PROKON Manufacturing and Erection Co. 5 % Joint Venture)

 

General Description Of The Project :

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, are being managed and implemented on a turn-key basis by Ekon-Prokon-Prokon JV, each of the party is a member of Ekon Prokon Group of Companies, totally with local Turkish engineering and contracting teams, with no foreign entity consortium or joint venture partnership.
