SUPERVISION CONSULTANCY SERVICES FOR “DESIGN, SUPPLY AND INSTALLATION OF GAS STORAGE

EXPANSION PROJECT”

1. Background

The Client, that is the Pipeline Corporation of Turkey (BOTAŞ), intends to expand the capacity of the existing Tuz Gölü underground gas storage (UGS) facility from 1.2 Bcm to 5.4 Bcm daily withdrawal capacity from 40 Million Sm3 to 80 Million Sm3 and injection capacity from 30 Million Sm3 to 60 Million Sm3. Project site is located approximately 200 km. south of Ankara in the central part of Turkey, approximately 40 km south of Tuz Gölü.

The objective of Gas Storage Expansion Project is to provide reliability and security of the natural gas supply by expanding the urgently needed gas storage capacity and deliverability for the national gas transmission and distribution network. Gas Storage Expansion Project will support the nation’s natural gas infrastructure to prevent any delivery constraints relating to the potential forthcoming peak customer demand.

The existing Tuz Gölü Underground Gas Storage Facility Contract, signed on 15 June 2011 following an International Competitive Bidding (ICB) process under a World Bank loan, is currently under implementation.

The Tuz Gölü UGS Project, well drilling has been completed for 12 wells, and the solution mining is ongoing for the Phase 2 caverns. First gas filling operation is completed in three caverns. These three caverns have been commissioned and in operation since December 2017, and all 12 caverns will be prepared for storage service by October 2021 with 1.2 Bcm of working gas capacity.

Gas Storage Expansion Project construction is set to begin in 2018 and involves drilling up to 40 wells and 8 additional (spare) wells, which would raise total storage working gas capacity to approximately 5.4 Bcm, the daily maximum withdrawal capacity to 80 million Sm3and daily gas injection capacity to 60 million Sm3.

The expansion project is planned to be constructed in an extension of the salt formation identified for the Tuz Gölü UGS. As in the current Tuz Gölü UGS project, the fresh water will be injected into the salt formation from the depth of 900 m to the depth of 1,500 m from the surface through wells constructed for that purpose. The caverns will be solution mined within the salt formation, each with net usable physical volume of 630,000 m³ to 870,000 m³. The brine generated during mining process will be discharged to the Tuz Gölü through a gravity pipeline. The natural gas will be taken from and returned to the main transmission line by a 40” diameter connection (header) pipeline 23 km in length. Natural gas will be stored in caverns under a maximum pressure of approximately 200 bars and will be withdrawn during times of peak demand in excess of contractual pipeline supplies or supply shortfalls.

Terms of Reference 2

A detailed environmental impact assessment (EIA) study was conducted to satisfy Turkish Environmental regulatory requirements and EIA Report was approved by the Turkish Ministry of Environment and Forestry (MoEF) on 10.03.2017. An Environmental and Social Impact Assessment (ESIA) Report and a Resettlement Policy Framework (RPF) Report were also prepared to meet the World Bank requirements. (See Section 8.1. Data/Reports for the links to ESIA and RPF reports.)

In parallel with the Supervision Consultant selection process, the Client will also initiate the procurement process regarding ESIA and RAP Monitoring Consultancy Services for the Gas Storage Expansion Project.

2. Objectives

The Gas Storage Expansion Project intends to construct a new facility capable of storing nearly 4.2 Bcm (working gas capacity) of natural gas, which will include the following activities as the task of the Contractor:

• Surface Facilities: This work component includes review of basic designs, preparation of detailed engineering and design of surface facilities that include; , pig stations, all necessary injection and withdrawal units, i.e. the compressor facility, with turbo compressor units and reciprocating compressor units, the gas treatment facility, with pressure reduction units, water separators, heating and tri-ethylene glycol (TEG) units, all auxiliaries, filters, fuel gas skid and vent stack, fiscal metering units, a control room, a utility building, worker’s camps and access roads.

• Subsurface Facilities: Under the expansion project, it is planned to drill and leach 40 wells with solution mining of 4.2 Bcm working gas within the licensed area. This work component includes review of basic designs prepared by BOTAS and , preparation of detail engineering and design, drilling of wells with adequate subsurface installation, solution mining of salt cavern space for gas storage purposes (each cavern with a free geometrical volume approximately 630,000 – 870,000 m³), first gas fill for each cavern, snubbing (removal of the de-brining string and installation of the production string) for each cavern, commissioning of each cavern and operation of all caverns until handover.

• Field Gas Pipeline System, Fresh Water Field Pipelines and Brine Field Pipelines: This component will involve design and construction of all field pipelines that transport natural gas from the gas facilities to and from the cavern sites, as well as field pipelines for fresh water and brine from the central pumping station to the cavern sites. • Fresh Water Supply and Brine Discharge Pipelines: This component will involve design and construction of a 117-km fresh water supply line (52-60” in pipe diameter) from Hirfanlı Reservoir to project site and a 31-km brine discharge line (64” in pipe diameter) from the solution mining plant to Tuz Gölü. The Fresh Water Supply Pipeline

Terms of Reference 3

involves construction of several pumping stations and storage reservoirs between the intake structure from Hirfanlı Dam reservoir and the Project Site.

• Electricity Supply: Project includes electricity transmission lines for the fresh water pumping stations, surface and sub-surface facilities.

• Natural Gas Pipeline: Gas pipeline interconnection (header) between Kayseri–Konya–Seydişehir section (approximately 23 km north of the Project Site) of the existing Eastern Anatolia Natural Gas Main Transmission Line (40” in pipe diameter) to the Expansion Project Site.

3. Project Implementation and Construction Process

Gas Storage Expansion Project is composed of two main components; (i) construction of all surface facilities related to gas transport, including gas compression, drying, metering and gas field pipelines; and (ii) construction of all surface and subsurface facilities related to transport of fresh water and brine, pumping stations, field pipelines and the drilling, leaching of 40 (plus 8 spare) caverns.

Surface facilities construction will be relatively conventional for gas storage, but with that of a compressor station with rather greater gas pressures than is normal in the pipeline industry. Be-cause of the many concurrent activities, construction, drilling, leaching, first gas fill and normal operations, the interaction between work activities on subsurface and the surface facilities does require specialized knowledge with high level of coordination.

Subsurface construction (drilling, leaching and first gas fill) of a cavern gas storage facility is a worldwide well-established activity; with experience of well drilling, brine and gas tubing in-stallation and circulation of large volumes of water. However, the expansion works are likely to be complex, especially because it will be adjacent to a fully functional storage plant in operation which will create ‘brown field’ complexity. Moreover, the subsurface construction peak periods will cover the simultaneous drilling of several wells with likely six drilling rigs operating in par-allel while the leaching of multiple caverns (up to 28) will take place simultaneously, with ap-proximately three-year solution mining period anticipated for each cavern. Therefore, contract-ing and managing the activities of all crews during the drilling and cavern completion process, with delivery and installation of well tubulars, proper installation of wellheads and solution mining strings, blanket equipment and control, sonar surveys, and management of solution min-ing string movements for up to 40 wells in various stages of construction activity will require a qualified construction management team with extensive experience in this area of construction. Finally, recognition that the critical first gas filling for several caverns are expected to overlap adding a layer of complexity that requires substantial material and personnel logistical support.

Hence, the Supervision Consultant’s planning and management contribution to the above given activities is critical for the proper and timely completion of the Gas Storage Expansion Project.
