Brief Project Description:

In Tuz Gölü Underground Storage Facility Expansion Project, working gas capacity of the existing storage plant will be increased to 5.2 billion Nm3 with the help of new 40 caverns. 6 of 40 new caverns will be leached by SF 1 (existing plant). For leaching of 34 caverns a new plant will be built Surface Facility 2 (SF2), consisting of leaching and gas facilities located, a fresh water supply system, brine disposal system, blanket system and gas injection & withdraw field pipeline system.

At the first step, leaching process will be done in new caverns to obtain required storage volume. During leaching process, fresh water from Hirfanlı Dam and nitrogen (blanket) gas from nitrogen unit system will be used. Brine, that is generated in leaching operation phase, will be transferred firstly from caverns to settlement basin and then disposed to the Tuz Gölü via gravity by Brine GRP pipeline. After completion of leaching process, caverns will be ready to fill with Natural Gas from Kayseri-Konya-Seydisehir transmission line. The new plant (SF2) will be located in North direction of existing Tuz Gölü SF1.

Brief CP Scope:

Cathodic protection is applied for the underground piping structures as per approved project design documents within the scope of “Tuz Golu Underground Gas Storage Project-2”. Kortek is selected to supply the materials for related Impressed Current System including 4 Transformer Rectifier Units, 6 horizontal (4+2 replacement) anode groundbed accessories (including MMO anodes, groundbed casings, coke breeze etc.) and other related equipment such as reference electrodes, cables, test posts etc. All materials have been produced and shipped successfully to site except TR Units and CP system is planning to be commissioned by the end of August 2021.
