2 Description0B of Approved Project
2.1 TAP1B Project Overview
2.1.1 Project4B Rationale
The purpose of the TAP Project is to bring gas from new sources in the Caspian Sea to Europe through the so called Southern Gas Corridor.
TAP Project will contribute to the security and diversity of Europe’s energy supply by providing the necessary infrastructure to transport gas from the Shah Deniz II field in Azerbaijan by the most direct route, via the pipeline system, to Southern Europe. As part of this plan TAP will be the first pipeline to open the Southern Gas Corridor.

The advances of the technical design of the Project and the consideration of the requests of various stakeholders during the ESIA public disclosure process have resulted in a number of changes to the pipeline system. It should be noted that such changes are rather limited taking into account the scale of the Project. Indeed, the number and type of installations have not changed. However, a number of rerouting proposals were integrated to the pipeline route while the location and design of some of the permanent and temporary installations was modified. These changes are described in detail in further sections of this ESIA Amendment study.
2.1.3 TAP6B System Throughput
Pipeline transportation capacity may be increased from an initial throughput of 10 bcm/year (maximum about 1,350,000 standard cubic meters per hour; average about 1,190,000 standard cubic meters per hour) to 20 bcm/year of natural gas.
The present ESIA Amendment does not introduce any changes to the TAP System Throughput as this was described in the ESIA for the TAP Project.
2.1.4 Project7B Schedule
At the time of ESIA submission, the overall construction of the Greek section of the Project was anticipated to commence in mid-2015 and take approximately 3.5 years, followed by commissioning in early 2019. The current planning of the Project suggests that the commencement of project construction will take place in mid-2016, while first gas flow is expected in the beginning of 2020.

2.1.5 TAP8B Design Philosophy
The TAP facilities (e.g. compressors and gas turbines) will be designed for a lifetime of 25 years. The pipeline itself is designed for a technical life time of 50 years. The design philosophy is to ensure that the gas transportation system fulfils all safety requirements of the base National and European Codes and Standards and that the impact to the environment is kept to a minimum.
The pipeline and stations will be designed in accordance with requirements resulting from:
• National and local regulations;
• Safety of the people living close to the pipeline and of personnel working near the pipeline;
• Protection of the environment;
• Protection of property and facilities;
• Geotechnical, corrosivity and hydrographical conditions;
• Requirements for construction, operation and maintenance;
• Third party activities.
The pipeline will have a design pressure of 95 barg (bars above atmospheric pressure), which will be sufficient for the TAP capacity base case of 10 bcm/year as well as for the potential future extension of the TAP System capacity to 20 bcm/year.
The present ESIA Amendment does not introduce any changes to the TAP Design Philosophy as this was described in the ESIA for the TAP project.
2.1.6 Applicable9B Codes and Standards
All Project facilities will be designed in accordance with the European Codes (EN) and National Standards. The EU and National standards must be followed and other standards will be used to supplement these where it is beneficial to do so.
For the TAP in Greece the main codes to be used are shown in Box 2-1.
Page 6 of 11 Area Comp. System Disc. Doc.- Ser. EXERGIA S.A. E.ON Technologies GmbH Code Code Code Code Type No. Project Title: Trans Adriatic Pipeline – TAP GPL00-EXG-642-Y-TAE-1003 Document Title: Section 2-Description of approved project Rev.: 00
Box 2-1: Main Pipeline Design Codes
• No Δ3/A/οικ. 4303 ΠΕ 26010 5/3/2012 “Technical Regulation: Natural Gas supply systems — Pipelines for maximum operating pressure over 16 bar”, as amended by No. Δ3/Α/8857 20/0/2012.
• EN1594:2009 “Gas supply systems — Pipelines for maximum operating pressure over 16 bar — Functional requirements”
A large number of other codes and standards will be applied for the design of project subsystems or individual project elements. These are presented in detail in Section 4.1.8 (GPL00-ASP-642-Y- TAE-0052) of the ESIA for the TAP Project. The present ESIA Amendment does not introduce any changes to the applicable codes and standards.
2.2 Main2B Project Components in Greece
2.2.1 Pipeline10B
The cross-country pipeline from the Greek/Turkish border to the Greek/Albanian border is approximately 543 km in length and has a diameter of 48’’. The design pressure of the main pipeline is 95 barg. The pipeline will be fully buried. The minimum cover depth for the pipeline is 1 m in normal sections, but this can be increased if necessary where additional protection is required. For example at road and railway crossings, the minimum cover depth is increased to 1.2 m and 1.5 m respectively.
The pipeline route, as presented in the ESIA for the TAP project, is shown in Annex 2.1: Overview map of Approved TAP Project and components in Greece.
The width of the regular construction working strip for the TAP Project is 38 m, and can be reduced to 28 m where physical constraints require. For construction in elevated areas the width will potentially be further reduced to a minimum 18 m corridor. Typical cross-sections of a regular working strip and a reduced working strip were presented in Annex 3.6 (GPL00-ASP-642-Y-TAE- 0052_at07) of the ESIA for the TAP Project.
All the above technical information relevant to the pipeline remains as presented in the ESIA for the TAP Project. The only changes are associated with a number of rerouting proposals, i.e. modifications / optimisations to the pipeline route, which are presented in detail in Section 3. Because of these changes, the total length of the pipeline will be approx. 548 km.

2.2.2 Block11B -Valve Stations (BVS)
According to the information provided in the ESIA for the TAP project, 22 BVS would be installed along the TAP pipeline in Greece, at maximum intervals of approximately 30 km. Their locations are shown in Annex 2.1: Overview map of Approved TAP Project and components in Greece (GPL00-EXG-642-Y-TAE-1003_at03). These locations were provisional, as the final design, depending on pipeline Risk Assessment, accessibility, national and international standards and an agreed operation and maintenance concept, will be performed at a later project stage.
The design of the block valve stations, as presented in the ESIA for the TAP project, is shown in Annex 2.2: Technical Drawings - Layouts and Flow Diagrams of Approved TAP Project (GPL00- EXG-642-Y-TAE-1003_at04). According to this design, block valve stations are unmanned and contain a small cabinet with a fence around them to prevent unauthorised access. Additional to the fenced area of approximately 12 x 33 m, a 3 m wide vegetation strip will be planted and an access road installed to provide permanent access during operation.
The current stage of the TAP project design maintains the same number of BVS along the pipeline route (i.e. 22 BVS) while an additional one will be installed in the place of installation of the Compressor Station in the area of Serres. It is reminded that this BVS will be upgraded to a Compressor Station when the TAP System Throughput increases to 20 bcm/year from the initial 10 bcm/year. The locations of the BVS as per the current stage of design are shown in Annex 4.1: Overview map of TAP Project modification in Greece (GPL00-EXG-642-Y-TAE-1004_at03). However, it is noted that the final locations of the BVS will be the result of the final Project design which will be performed at later project stage.
The current stage of design has also revealed some additional information for the design of the 2 BVS. They will comprise small buildings with total building surface of 33 mP .P Details on the BVS are provided in Section 3 of this document.
2.2.3 Compressor12B Stations (CS)
2.2.3.1 Configuration14B
The pipeline’s initial transportation capacity is characterised by a throughput of 10 bcm/year and will potentially be increased to 20 bcm/year.
According to the information provided in the ESIA for the TAP Project, for the initial capacity of 10 bcm, one compressor station in the broader area of Kipoi (GCS00) is foreseen of approximately
Page 8 of 11 Area Comp. System Disc. Doc.- Ser. EXERGIA S.A. E.ON Technologies GmbH Code Code Code Code Type No. Project Title: Trans Adriatic Pipeline – TAP GPL00-EXG-642-Y-TAE-1003 Document Title: Section 2-Description of approved project Rev.: 00
30-45 MW (2 operating and 1 spare compressors of 15 MW, each). For the 20 bcm case the compressor station GCS00 needs to be developed to 75-90 MW by installation of three additional compressors (15 MW, each) with associated facilities (total capacity 5 operating and 1 spare compressors, 15 MW each). Furthermore one additional compressor station located in the vicinity of Serres (GCS01) with a compressor power of approximately 100 – 125 MW (4 operating and 1 spare compressors of 25 MW, each) is foreseen in the 20 bcm case. The indicated MW-figures are related to ISO class. The actual figures may deviate slightly.
In summary, the configuration of the compressor stations, as presented in the ESIA for the TAP pipeline project, is given in the Table below.

2.2.3.2 Layout15B and design
As presented in the ESIA for the TAP Project, TAP has defined an area of 36 ha for the investigation of each of the CS sites, within which the CS will be positioned during the final engineering phase. The compressor station facilities GCS00 and GCS01 require a surface of 16.7 ha and 16.3 ha correspondingly. This area will be fenced. Within this surface, about 10 ha will be hosting installations, buildings or roads. In each compressor station, a scraper station will be installed.
2.2.4 Temporary13B Facilities
2.2.4.1 Storage16B and Pipe Yards
According to the ESIA for the TAP project, all key material for project construction such as pipes, components of the compressor stations and special construction equipment would be shipped to the port of Thessaloniki, Kavala and Alexandroupolis.
There would be an intermediate storage yard close to the main port at Thessaloniki ,Kavala and Alexandroupolis which would have sufficient pipe storage capacity to provide buffer storage in case of construction delays. Pipes would be distributed from the intermediate storage yard to the

The current stage of design has introduced a number of changes to the logistics concept described in the ESIA. All key material for Project construction such as pipes, components of the compressor stations and special construction equipment will be shipped to the port of Thessaloniki or Kavala. The location of the pipe yards has also been modified. Details on these changes will be presented in Section 3. The locations of the pipe yards as per the current stage of design are shown in Annex 4.1: Overview map of TAP Project modification in Greece.
The use pattern for the pipe yards has remained the same as described in the ESIA for the TAP Project. All pipe yards will be fenced, lighted and guarded. All installations are of temporary character and will be removed completely (including foundations) after the construction period. The entire area will be vegetated after demobilisation of infrastructure.
2.2.4.2 Construction17B Camps
According to the ESIA for the TAP project, there would be 8 main construction camps along the route. Nevertheless, the Contractor will have the opportunity to optimize his working concept and operate additional camps if required.
The camps will be temporary, self-contained. They will have their own water and electrical supply as well as facilities for wastewater and garbage treatment. Camp staff will provide housekeeping, meal services and medical services. Fresh water will be provided from existing water supplies if available or alternatively from springs in the camp’s surroundings. All wastewater will be treated according to national requirements prior to dewatering in a river or leaching.
The sites proposed as suitable for camps in the ESIA are described in the following Table along with their approximate capacities.

These locations do not include the camps for the compressor stations, which will be built by a separate contractor, hence they will be independent from the camps of the pipe laying contractor. Neither do they include temporary small camps for construction works at special points (e.g. larger river crossings and BVSs). The teams of these small camps will not stay there overnight but be based in nearby hotels or main camps.
As described in the ESIA for the TAP Project, all construction camps will be fenced, lighted and guarded. All the construction camps are of temporary character and will be removed completely (including foundations) after the construction period. The entire area will be vegetated after demobilisation of infrastructure.
The current stage of design has introduced some changes to the location of the camp sites along the pipeline route. Details on these changes will be presented in Section 3. The locations of the construction camps as per the current stage of design are shown in Annex 4.1: Overview map of TAP Project modification in Greece.
