1 Background
1.1 Description of the Gas Transmission System
The Government of Israel intends to further develop the natural gas transmission system
based on the updated Master Development Plan (not finalized) of the COMPANY and
the local market demand. This involves the establishment of a natural gas infrastructure
project of national significance. This also entails the introduction of international state-of-
the-art codes and other standards, other authorities procedures, supply security and the
consideration of environmental aspects.
Feed-in to the system are from offshore pipelines from the Israeli production platform
Merry B (Mary B) and an Egyptian supplier (EMG). The battery limit for the system to be
considered is the transmission point to the Receiving stations in Ashkelon and in Ash-
dod. The offshore supply pipelines which are landing in are not part of this manual.
The existing transmission system, which is under operation, is divided into four main
parts: Offshore pipeline Ashdod – Reading (Tel Aviv) – Dor; Phase 1 (Ashdod – Nesher
+ Ashkelon – Qiryat Gat – Soreq); Phase 2 (Qiryat –Gat – Sdom (Dead Sea)); and
Phase 3 – Northern Section (Dor – Tel Kashish – Haifa, Tel Kashish – Alon Tavor). The
existing parts of the system consist of approx. 400 km of onshore and offshore pipeline
with different diameters and 18 gas delivery points to customers (power plants, industrial
areas, cities, etc.).
Up to year 2017, the COMPANY is planning to design, build and operate additional ~
350 km of onshore pipelines and at least 30 gas delivery points to customers (PRMS).
The current development plan of the Company includes the construction of high pres-
sure natural gas transmission pipelines and valve stations in the following sub – projects
(Sections):

5. Design
5.1 Basic Design
The principles to be obeyed for project, design, construction, operation and maintenance
of gas pipelines are fixed in the Natural Gas Market Law - 2002, the Gas Law (Safety
and Licensing) – 1989, the Gas Order (Safety and Licensing)(Facilities for Transporting
Natural Gas) – 1997 and furthermore by the National Outline Plan for the Natural Gas
Transmission System in Israel No. 37 (TAMA 37) including all its derivatives.
According to the above Law and the TAMA 37, the design basis for the pipeline system
are the following international standards (latest edition):
o NEN 3650 (Main Standard, by Law*)
o ASME B 31.8
o ASME B 16.5
o ASME B 16.9
o API 5 L
o API 6 D
o API 1104
In addition, other international recognized and accepted codes like EN Standards,
DVGW G Standards, VdTÜV and AD Leaflets, ASME-Guide and ASTM Standards have
been applied on design calculations and material selections.
Transport pipelines shall be designed and constructed in such way that the probability of
a limit state being exceeded during the planned service life is sufficiently low.
Design Pressure (DP) = 80 barg
Design Temperature
Maximum (underground) = +50 °C
Maximum (above ground) = +65 °C
Minimum = -10 °C

Pipelines of the transmission system are "Piggable" therefore using Hot formed bends
must be included and will be fabricated with a minimum radius of R = 10 x D.
In dedicated areas hot formed bends of R= 5 x Dout can be used when decided by the
designer.
The design for the vent stack and bypass diameter is based on need of venting pipeline
section within an hour.
5.1.2 Corrosion Protection
All buried parts and components of the gas transmission system, including the joints and
welds, shall be primarily protected against corrosion with an external coating (Passive
cathodic protection).

the cathodic protection measurement cable and one spare (three conduits
in total)
Bends
The three types of bends to be used for the “pigable” pipeline sections are hot-formed
bends, field bends and elastic bends.
Hot-formed Bends:
Pipelines of the transmission system are "Piggable" therefore using Hot formed bends
must be included with a minimum radius of R = 10 x D.
In dedicated areas hot formed bends of R= 5 x Dout can be used when decided by the
designer

quirements of EN Standard No. 13480-3.
Field Bends:
Field Bends shall be made on site according to the relevant specification.
The maximum out-of -roundness of field bends shall not exceed 3 %.
The radius of field bends, taking into consideration bending steps, bending angles and
the length of straight pipes required at each end of a bend shall not be less than 40
times the outside diameter of the pipe.
Elastic Bends
Elastic Bends shall be used for minor changes in direction or elevation and shall not be
less then 1000 times the outside diameter of the pipe. 5.1.9 Special Construction Considerations
Special Soil Conditions
Swampy and Flood Areas
In all areas with a groundwater level (primary or secondary) or potential groundwater
levels (i.e. flood areas) above the pipe bottom, and organic soil, the buoyancy will be
compensated with concrete flotation shells or other constructive measures. The safety
factor against buoyancy shall be 1.3.
Steep Slopes Areas with Soil Erosion
In slope areas, erosion and washout of the soil covering the pipeline is possible. To
avoid this, precautions have to be taken, using one of the following methods:
o Pipe Protection in Washout Area (concrete shells etc.)
o Protection Against Erosion with Sand Bags
o Protection Against Erosion with Sand-Cement Bags
o Protection Against Erosion with Concrete Wall

Information.doc
Additional unforeseen areas of erosion shall require the CONTRACTOR to engage the
ser- vices of specialists to resolve the various Geographical conditions.
Rocky Areas
In the rocky areas, the pipeline shall have at least 1.2 m cover. In such areas, the pipe-
line shall also be surrounded by sand padding with a thickness of at least 20 cm, and
where necessary additional, with rock shield.
5.1.10 Cathodic Protection System
In accordance with the applicable standards, the entire below ground pipeline system
shall be protected passively by coating and actively by an impressed current cathodic
protection system, which consists of two major components:
1. The CP stations with anode ground beds and transformer / rectifier units and
2. Test points for regular checking of the system operation.
The requirements for operation of a cathodic protection system are listed below:
o the entire pipeline system shall be polyethylene coated
o the pipeline shall be electrically isolated from steel casings and reinforced
foundations at valves, vent stacks and scraper traps
o instrumentation and devices (e. g. electric actuators) require electrical
earthing isolated from the pipeline by insulating couplings
o max. pipeline temperature 50°C
Temporary cathodic protection system shall be installed for the pipeline from the begin-
ning of the construction.
At all points where the soil resistively survey indicates a soil resistively of less than 20
ohms x m, the permanent cathodic protection system shall be installed and energized
immediately after the pipeline has been backfilled. Where this is not possible, a tempo-

rary cathodic protection system using sacrificial anodes (Mg) or impressed current shall
be installed and operated after backfilling.
The potential criteria of UoffCu/CuSO4 = 0.95 V must be achieved as a minimum.
The CONTRACTOR shall ensure that the temporary cathodic protection systems with
impressed current or Mg anode is adequate for at least 2 years of independent opera-
tion.
5.1.11 Electrical, SCADA, Station Control and Telecommunication System
The main operational requirement for delivery of contracted volumes to the market is to
maintain the flow of natural gas through the pipeline and reduce the downtime to an ab-
solute minimum. This requirement can be achieved by operating the pipeline network as
close as possible to its maximum efficiency enabling rapid identification of abnormal
conditions of flow or growth of unaccounted volumes and verifying instrument inaccura-
cies.
Main criteria to get this achieved is the implementation of reliable field proven state-of-
the-art equipment in combination with a proper redundancy concept for all main electrical
equipment at the stations, for the communication and in the Dispatching Centers.
Pressure regulating and metering stations and block valve / scraper trap stations shall be
designed for unmanned operation. However, at all stations remote operating capabilities
are required.
In case of failure of the Supervisory Control and Data Acquisition (SCADA) system the
control of the stations shall be maintained, so that a hazardous situation can be pre-
vented

7.2 Environmental Impact Assessment
The Environmental Impact Assessment was approved during the Detailed Engineering
Phase. The CONTRACTOR is required to implement all the recommendations, and
strictly adhere to all constraints, identified in the Environmental impact Assessment.
7.3 Traffic Plan
Prior to the commencement of any pipeline construction activity, a detailed and compre-
hensive traffic plan shall be developed in close coordination with Local, Regional, and
National Agencies. The traffic plan shall identify all highways, roads, tracks, and access-
es authorised for use by construction traffic. Construction traffic shall not travel on any
public or private land, roads, or tracks, except where expressly permitted to do so by the
traffic plan.
7.4 Access to the Right of Way
Where access is granted from asphalt paved highways and roads, an area of compacted
crushed stone shall be constructed to mitigate damage to the existing road surfaces. All
pipeline stations shall be furnished with all weather access roads. The need for new
roads, or access from existing roads to pipeline stations, shall be determined during the
Detailed Design Phase. All access roads and access points shall be subjected to regular
maintenance and upkeep.
7.5 Route Alignment
Preliminary 1:5,000 scaled Plot Plans are providing the approved route corridor (100 m)
according to the TAMA. During the Detailed Engineering Phase, this route shall be veri-
fied by conducting detailed surveys together with thorough soils and terrain evaluations.
7.6 Definition of the Working Width
The pipeline ROW working width is depending on the pipeline diameter and can be up to
28 m for a 30" pipeline. However, there will be certain areas of restricted working, which

shall be defined during the Detailed Engineering Phase following approval of the Envi-
ronmental Impact Assessment.
7.7 Land Liaison
Experienced Land Liaison Officers shall be employed, with the prime responsibility of li-
aising with all Landowners, Occupiers, and Local and Regional Authorities along the
pipeline route. Prior to any entry onto the pipeline ROW for construction purposes, the
Land Liaison Officers shall agree and compile a Pre-Entry Condition Log with all land
users.
7.8 Marking of the Working Width
The CONTRACTOR shall establish and maintain permanent reference points along the
pipeline route to create a pipeline geodetic network. The limits of the working width, and
any extra working width required at crossings, shall also be marked by staking. The pipe-
line trench centreline shall be established and any stakes disturbed or removed prior to
the trenching operation shall be replaced.
Kilometre point markers shall be placed at the ROW boundaries for progress reporting
purposes. Stakes and markers shall not be removed until ROW restoration. Any perma-
nent reference point disturbed or removed shall be immediately replaced.
7.9 Existing Foreign Services
Liaison shall be established with Local and Regional Authorities to identify and locate all
known foreign service crossings, both overhead and underground. All foreign services
shall be located, adequately protected, and clearly signposted throughout the construc-
tion period.

approved disposal area. All ROW clearing debris shall be removed offsite, and shall not
be allowed to foul watercourses. The burning of brushwood or any other material is not
permitted on the ROW. Saleable timber shall be cut into manageable lengths and
stacked to the side of the ROW, for disposal as directed. Care shall be taken to protect
all survey markers during the operations.
7.10.2 Topsoil Stripping
The Pre-Entry Condition Log will define areas to be topsoil stripped. Where topsoil strip
is requested for the full working width, the full depth of topsoil (to a maximum depth of 30
cm) shall be pushed to the running track side of the ROW to ensure topsoil and subsoil
remain segregated during the trenching operations. In areas of wetlands and peat, top-
soil stripping should be avoided where possible, to maximise the ground bearing capaci-
ty of the soils.
7.10.3 Grading the ROW
The working width shall be graded, only as much as to provide a safe and level running
track and working strip, and where practical, minimise the requirement for cold field
bending. Grading operations shall be confined to the limits of the working width, and any
agreed additional working areas. Specific procedures shall be developed for the grading
or benching of steep slopes and side slopes. Under no circumstances are the banks of
any watercourse to be breached, until such time as crossing installation is imminent.
Survey markers removed during grading operations shall be replaced.
7.10.4 Cross Spread Accesses
Where directed by the Pre-Entry Condition Log, accesses shall be provided across the
working width for landowners, pedestrian, and livestock traffic. Care shall be taken to
fence off potential danger areas such as open excavations, spoil heaps, and other such
obstructions.

tions in flow, with regard to flume pipe sizing, and freeboard under bridges. The crossing
point shall be constructed to effect a smooth and safe transition between the crossing
and the running track. Construction equipment shall not be permitted to ford watercours-
es.
7.10.7 Fencing
The CONTRACTOR shall supply and install fences along the working strip. The fences
shall be made of at least 3 mm fabric (wire mesh).
7.11 Pipe Dumps (Pipe Storage Yards)
7.11.1 General
In order to avoid excessively long hauls to, and from the ROW, it is inevitable that sever-
al pipe storage dumps will be necessary along the route. Suitable and acceptable loca-
tions shall be selected, and agreements negotiated with the Landowner/Occupiers. Local
Authorities must be consulted in order to obtain the necessary temporary planning con-
sent. The locations of all temporary pipe dumps must be taken into consideration when
formulating the traffic plan.

and coating damage. Tag lines shall be attached to both ends of the pipe, to control
movement when the pipe is in the slung position. The pipe lengths shall be inspected
during offloading and all defects shall be marked. Where practical, coating repairs shall
be effected prior to load out.
7.11.3 Stacking of Pipes
All lifting plant and equipment shall be suitably padded, to avoid damage to the pipe or
coating during offloading/stacking. Pipes shall be stacked on timber or steel grillages,
suitably cushioned to avoid pipe coating damage; or on sand rows, covered with a poly-
thene sheeting material. Pipes of differing wall thickness shall be stacked separately.
7.12 Load, Haul, and String
7.12.1 Pipe Loading
Pipes shall be loaded and unloaded using side booms or cranes. Tag lines shall be at-
tached to control pipe movement when in the slung position. Lengths of pipe shall be
separated by protective pads, or nylon rope hoops. Where trailer side supports are used
to secure loads, they shall be padded to prevent coating damage. Nylon straps or similar
shall be used for securing pipes to trailers, strap tightening buckle devices shall not
make contact with the pipe coating.
7.12.2 Pipe Hauling

mise the possibility of trench collapse. Open trenches shall be kept free of water. Where
conventional pumping equipment is inadequate, dewatering systems must be consid-
ered. Whenever necessary, trench support systems shall be installed to safeguard the
stability of the excavation.
7.13.2 Underground Utility Crossings
Prior to any excavation activity in the vicinity of existing underground utilities, the authori-
ty having jurisdiction over the service shall be notified. Such notification, shall allow suffi-
cient time for the relevant authority to have a representative present, during the excava-
tion operation. All utilities at crossings shall be fully exposed, and where necessary ade-
quately supported or relocated.
7.14 Bedding Excavation
On completion of the excavation, sand bedding has to be performed. The layer thickness
should be 0,2m. The surface of the excavation base shall be free of all defects that are
liable to cause local loads on the pipeline. In addition, the soil on the excavation base
must be free of all organic material, stones, rocks, boulders and waste.
During the course of trench excavation, the excavation base shall be deepened by about
20 cm below the planned pipe laying depth. The resultant empty space shall be filled
with a bedding layer as detailed in the drawings.
Details see COMPANY Specification EEN-CSE-SPC-010 and EEN-CSE-SPC-014.

from the true bed level to the top of pipe shall be not less than 1.5 m. Above ground
crossings shall not be used.
Under no circumstances shall the banks of any watercourse be breached, until installa-
tion of the fabrication is imminent.
Various construction techniques are used for open-cut watercourse crossings, and as-
sessment should be made on a case-by-case basis, which shall dictate the particular
technique to be adopted.
For drainage ditches and dykes, where annual ditch cleaning is likely to occur, a protec-
tive concrete slab should be placed in the backfill. The slab should be situated a mini-
mum of 30 cm below the firm ditch bottom.
Pre-cast concrete irrigation channels shall normally be crossed by one of the bored
crossing techniques, to avoid disturbance and disruption to the irrigation system.

7.23 Backfilling
7.23.1 General
All pipeline backfilling shall follow as closely as possible to the lower and lay operations.
Therefore the contractor shall coordinate all operations in advanced. The CONTRAC-
TOR has the responsibility to ensure (where possible), that the trench is kept free of wa-
ter during backfilling.
7.23.2 As Built Survey
Prior to the commencement of any backfilling, survey crews shall record all the data
necessary for the as built survey, to comply with the requirements of the Contract Docu-
ments and Specifications.
7.23.3 Pipe Protection
Care shall be taken during the initial stages of backfilling to ensure that the intimate
backfill reaches around and under, all quadrants of the pipe. Initial stage backfill should
be carried out by backhoes, in order to place the material around and over the pipe, and
to avoid dropping the backfill from an unacceptable height.
Where suitable intimate backfill cannot be imported, or achieved by screening, a rock-
guard type material shall be used to protect the pipe coating. Under no circumstances
shall topsoil be utilised as intimate backfill.
7.23.4 Backfill
When the initial stage backfill has been compacted, second stage backfill can be ac-
complished by pushing in the native material with bulldozers, working at right angles to
the trench line. Backfill material shall be free of carbonaceous material i.e. tree roots,
branches etc. Backfilling shall be completed in not more than 30 cm compacted layers.
Each subsequent layer being properly compacted to the same consistency as the sur-
rounding soil, up to the underside of the topsoil level.
