of 61

5.9. Pipeline Components

5.9.1. Line Pipe

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

with polyethylene in accordance with the coating specifications.

pipeline diameter = 36“= X70

pipeline diameter = 30”= X60

24" ≥ pipeline diameter ≥ 20”= X70

18" ≥ pipeline diameter ≥ 8“ = X52

pipeline diameter ≤ 6”= Grade B

5.9.2. Casing Pipes

5.9.2.1. 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.

5.9.2.2. The diameter of the pipes used as casings shall be approx. 300 mm larger

than the diameter of the line pipes. The wall thickness and length

and approved crossing technique, and shall be equipped with a coating

sufficiently resilient to minimize damage during installation.

5.9.2.4. Line pipes shall be electrically isolated from casings using plastic

Isolating spacers

Polyethylene pads (saddles)

of 61

Casing end seals

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)

5.9.3. Bends

The three types of bends to be used for the “pigable” pipeline sections are

hot-formed bends, field bends and elastic bends.

5.9.4. 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 D can be used when decided by the

designer

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

requirements of EN Standard No. 13480-3.

Field Bends shall be made on site according to the relevant specification.

The maximum out-of -roundness of field bends shall not exceed 3 %.

Elastic Bends shall be used for minor changes in direction or elevation and shall not

be less than 1000 times the outside diameter of the pipe.

5.10. Special Construction Considerations

5.10.1. Special Soil Conditions

5.10.1.1. 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.

of 61

5.10.1.2. 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:

Pipe Protection in Washout Area (concrete shells etc.)

Protection Against Erosion with Sand Bags

Protection Against Erosion with Sand-Cement Bags

Protection Against Erosion with Concrete Wall

5.10.2. Additional unforeseen areas of erosion shall require the Contractor to engage the

services of specialists to resolve the various Geographical conditions.

5.10.3. Rocky Areas

In the rocky areas, the pipeline shall have at least 1.2 m cover. In such areas, the

pipeline shall also be surrounded by sand padding with a thickness of at least 20

cm, and where necessary additional, with rock shield.

5.11. Cathodic Protection System

5.11.1. 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.

5.11.2. The requirements for operation of a cathodic protection system are listed below:

the entire pipeline system shall be polyethylene coated

the pipeline shall be electrically isolated from steel casings and reinforced

foundations at valves, vent stacks and scraper traps

instrumentation and devices (e.g. electric actuators) require electrical earthing

isolated from the pipeline by insulating couplings

max. pipeline temperature 50°C

5.11.3. Temporary cathodic protection system shall be installed for the pipeline from the

beginning of the construction.

5.11.4. 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

of 61

possible, a temporary cathodic protection system using sacrificial anodes (Mg) or

impressed current shall be installed and operated after backfilling.

5.11.5. The potential criteria of UoffCu/CuSO4 = 0.95 V must be achieved as a

minimum.

5.11.6. 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

operation.

5.12. Electrical, SCADA, Station Control and Telecommunication System

5.12.1. 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 absolute 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

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, topsoil stripping should be avoided where possible, to

maximize the ground bearing capacity of the soils.

6.10.3. 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, minimize the requirement

for cold field bending. Grading operations shall be confined to the limits of the
