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

5.1.1 Design Data for Pipeline Stations

Page 19 of 89 89



Information.doc

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).

For the coating on site shall be prepared.

An temporary active cathodic protection system has to be installed from the begining of

the construction, until the final cathodic protection system has been installed and com-

missened.

5.1.3 Crossings

In crossings with all Highways, National Roads, Railways and selected Municipality

Roads shall be installed without casing pipe if it has been approved by third party owner.

Nevertheless, if the installation can't be done with open cut, the carrier pipe shall be de-

signed for the category of the area where the crossing is located in. The pipeline shall be

laid without bends under roads with an improved surface (asphalt, concrete slabs).

Diameter of pipes used as casings shall be approx. 300 mm larger than the diameter of

the line pipes.

At cased crossings, the fiber optic cable (if applicable) shall be carried through the pipe-

line casing pipes in separate HD-PE cable conduits installed inside the casing pipe.

At water crossings such as small rivers, streams and ditches, the pipeline shall be in-

stalled by the open cut method (if not requested by authorities otherwise) and protected

against buoyancy.

Page 20 of 89 89



Information.doc

Crossing of infrastructures, facilities, private lands etc, shall be coordinated with all par-

ties including COMPANY operation department. The coordination should be considered

in the design and construction.

5.1.4 Marking of the Pipeline

Warning Tape

A warning tape shall be placed at 0.3 m above the top of pipe over the whole length of

the pipeline between stations. See spec in Annex BB3

Marker Posts

Marker posts shall be installed to mark the position of the installed pipeline. The location

of marker posts shall be determined during the detail design.

Marker posts to mark the position of the pipeline shall be installed with a spacing of max.

500 m, but all changes of direction and other characteristic points along the route shall

also be identified. Major crossings shall be supplied with pipeline marker posts at both

sides of the crossing. See spec in Annex BB3

5.1.5 Depth of Cover

The depth of cover for the pipelines will be adapted to local conditions. The normal min-

imum depth of cover shall be 1.2 m and in additional the expected erosion for at least 30

years.

The minimum depth of cover at crossings shall be designed considering the minimum

required and third party requirements at crossings.

The actual depth of cover shall be indicated on the Construction Drawings for the rele-

vant crossing sections.

5.1.6 Pressure Testing

Page 21 of 89 89



Information.doc

After construction, the pipeline shall be pressure tested to demonstrate the strength of

the pipeline and its leak-tightness, acc. to NEN 3650-2: 2003 and COMPANY specifica-

tion EEN-CSE-SPC-012.

The pipeline shall be subdivided into test sections which maximum lengths should not

exceed 15 km and / or the volume of the sections should not exceed 6000 m3.

The following pressure values are the minimum test pressures (at the highest point of

test section), dependent on class location:

Category Test Fluid Minimum Test Pressure

1 Water 1.5 x DP 2 Water 1.5 x DP 3 Water 1.5 x DP 4 Water 1.5 x DP

Test procedures shall be supplied by the CONTRACTOR for each test section to ensure

that the maximum stress (based on the minimum wall thickness) at the low points shall

not exceed 95% of the Specified Minimum Yield Strength (SMYS) and the stresses at

the high point is minimum 80% of SMYS (based on the maximum wall thickness) of the

pipe material. See spec in Annex BB3

5.1.7 Pipeline Stations

All pipeline equipment which contain above ground components as valve actuator or

hand wheels, scraper traps, vent stacks, etc., shall be installed in fenced areas with

lockable gates to prevent unauthorized access. The ground surface of all pipeline sta-

tions shall be gravel inside the fenced area.

Security measures shall be carried out such as concrete fences and other physical pro-

tection means.

Electrical, Instrumentation (including SCADA), lighting etc, shall be considered also in

accordance with Hazardous Area Classification (Explosion proof devices etc).

The main pipeline shall be laid at a minimum depth of cover of 1.2 m at all Stations.

However if the cover will be less than 1.2 m for design reason additional protection

measures shall be chosen.

Page 22 of 89 89



Information.doc

Station piping and -components as valves and fittings shall have a design factor of at

least 2.0, pipes in vent lines usable for blow down operations shall have a design factor

of 2.5.

All valve controls and other equipment which needs to be operated and maintained

should be with easy access and above ground preferably.

Buried valves and other specified items shall be installed on concrete foundations

grouped on concrete plates. All buried equipment shall be electrically insulated from rein-

forced concrete foundations by insulation mats or plates.

To avoid introduction of additional stresses, the equipment should not be fixed on foun-

dations, unless it is stated otherwise or shown in the design. In general, sliding foils will

be placed between foundation and equipment as it is shown on the standard drawings.

5.1.8 Pipeline Components

Line Pipe

Line Pipe shall be spiral or longitudinally welded. All line pipes are factory coated with

polyethylene in accordance with the coating specifications.

Line pipes >DN 450 are internal coated by Epoxy to reduce the roughness of pipe sur-

face and thereby reduce pressure loss.

The material grade for the line pipe shall be as follow:

o pipeline diameter = 36“= X70

o pipeline diameter = 30”= X60

o 24" ≥ pipeline diameter ≥ 20”= X70

o 18" ≥ pipeline diameter ≥ 8“ = X52

o pipeline diameter ≤ 6”= Grade B

Casing Pipes

Casing pipes shall be installed at major crossings as required in the design. Pipes to be

used as casings will be in accordance with API 5L.

Page 23 of 89 89



Information.doc

The diameter of the pipes used as casings shall be approx. 300 mm larger than the di-

ameter of the line pipes. The wall thickness and length calculations for the casing pipes

are made employing the German Code VdTÜV 1063.

Casing pipes at road- and railway crossings shall be installed by a closed crossing tech-

nique, and shall be equipped with a coating sufficiently resilient to minimize damage dur-

ing installation.

Line pipes shall be electrically isolated from casings using plastic isolating spacers with

slides and without any metal parts. The annular space between the line pipe and the

casing shall be sealed at both ends. A test post shall be installed at each casing to moni-

tor the effectiveness of the insulation between the line pipe and the casing.

Casing pipe configurations shall be designed with conduits for cathodic protection and fi-

ber optic cables and shall be equipped with the following accessories:

o Isolating spacers

o Polyethylene pads (saddles)

o Thrust blocks and anchors

o Casing end seals

o Cable conduits for the fiber optic cable and a separate cable conduit for

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

Page 24 of 89 89



Information.doc

The wall thickness has been calculated by the manufacturer in accordance with the re-

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

Page 25 of 89 89



Information.doc

Additional unforeseen areas of erosion shall require the CONTRACTOR to engage the

services 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-

Page 26 of 89 89



Information.doc

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

5.2 Design Documents

The design documents provided by COMPANY to CONTRACTOR would be based on

initial survey of the Site and the information known to the COMPANY's during the design

phase.

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

Page 37 of 89 89



Information.doc

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.

7.10 ROW Preparation

7.10.1 Clearing the ROW

The contractor shall clean the Site before commencement of the works. All existing tree

stumps, saplings, bushes, and scrub within the working width shall be taken off site to an

Page 38 of 89 89



Information.doc

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.

Page 39 of 89 89



Information.doc

7.10.5 Overhead Utility Lines

The particular requirements of the Governing Authorities for overhead utility lines with

regard to safety barriers and warning signs shall be strictly observed. Crossing points

must be clearly identifiable by construction equipment operators.

7.10.6 Fluming and Bridging of Watercourses

All natural watercourses shall be flumed or bridged, and designed in order to maintain

flow and minimise disturbance. Special consideration shall be given to seasonal varia-

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.

7.11.2 Receipt and Inspection of Line Pipe

A formal computerised control system shall be developed and approved, for recording

materials throughout receipt, storage, issue, and installation. Pipe lengths shall be han-

dled by using slings, pipe hooks, and spreader bars, suitably protected to prevent pipe

Page 40 of 89 89



Information.doc

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

Road hauling trailers shall be purpose rigged, and fitted with fender guards to prevent

road debris damaging the pipe coating on the overhang. All pipe hauling activities shall

comply with the approved traffic plan. Sufficient trailers shall be employed to ensure a

continuous supply of line pipe to the stringing operations.

7.12.3 Pipe Stringing

Whenever possible, pipe lengths shall be strung directly from road going transport.

Where ground or weather conditions do not allow this, pole trailers and tractor units, or

pipe carriers shall be used. Pipe lengths shall be supported on pack pads and timber

Page 41 of 89 89



Information.doc

skids, or other approved methods. Changes in line pipe wall thickness shall be designat-

ed on the alignment sheets. Gaps in the stringing shall be left where requested by land-

owners, and beneath overhead power lines.

7.13 Trenching

7.13.1 Excavation

The excavation/rock excavation works shall be carried out in accordance with the work

safety instructions (revised version) and work safety regulations (construction works), as

well as any additional and updated instruction of the Ministry of Labor and the Safety and

Hygiene Institute relating thereto, and any relevant additional law.

The excavation works include:

• Excavation. • Storage of the excavated material and separation of topsoil, which is suitable for

backfill. • Loading, transport from the site and dispersion of the surplus material at a dump-

ing site to be determined by the COMPANY. • Any additional work required for proper performance of the excavation works

The centreline of the trench shall be marked by the construction survey team. Generally,

in reasonable ground conditions, the trench is dug with conventional backhoes. The

trench bottom width shall exceed the pipe diameter by the specified margin, to ensure

proper backfilling and compaction.

The trench bottom shall be prepared to permit even bedding of the pipe, and shall be

free of all objects and material, which could be injurious to the pipe or coating. Minor var-

iations in contour shall be excavated to minimise cold field bending. In rocky ground

conditions, heavy backhoes, rippers, and hydraulic hammers may be necessary. In are-

as of hard rock conditions, a rocktrencher should be considered.

Page 42 of 89 89



Information.doc

Excavated spoil shall be deposited at a safe distance from the lip of the trench, to mini-

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
