3. The Chainages for new ROU are measured from ONGC Bantumilli, and increases towards DMPL

4. The Chainages for existing ROU are measured from Ullamparru, and increases towards DMPL

5. The Design Cumulative chainage are given for cross checking, and are measured from ONGC Bantumilli

towards Ulamparru.

The above methods proposed for the crossings are tentative. However, the actual method of crossing shall be

finalized based on actual site requirements.

In addition to the above, the initial 6.6 kms length (approx..) of proposed pipeline route, starting from TP-07 near

ONGC Bantumilli (chainage – 0.424 km), and upto TP-50 (chainage : 7.0463 km) has a very restricted width of

ROU available. This section of pipe route runs adjacent to existing road and State Highway-113. This section has

been considered as HDD section.

Since the length of the pipeline section is large, (approx. 6.6 kms), the pipeline laying shall be done using multiple

HDDs. The depth of HDD shall be kept adequate to safeguard the pipeline from effects of seepage, waterlogging

and earth loads. The following shall be considered:

a. The exact location, length and starting & end points of the HDD crossings shall be determined based on

actual site conditions, and availability of space and permissions for carrying out HDD operation, and ease

of installation and movement of required equipment.

b. To the extent possible, most of the portions of the above section shall be preferably installed by HDD

Method. The sections where major construction constraints are likely shall be included in crossings by HDD.

c. The no. and locations of HDD sections shall be decided based on site conditions and requirements,

availability of adequate space for carrying out the operation, movement and installation of equipment, and

ease of hooking up of different HDD sections.

d. The depth, routing and exact profile of the HDD shall be finalized based on site conditions and actual site

requirements.

e. The sections where it is possible to lay the pipeline by trenching, shall be carefully evaluated and agreed by

the client / PMC. All such sections shall be hooked-up with adjacent HDD sections, ensuring a smooth

pipeline profile for ensuring that all pipeline stresses are within design limits.

f. Adequate protection against earth/vehicular loads in form of concrete slabs etc. and adequate anti-buoyancy

measures like concrete-coating, saddle bags or pre-cast concrete weight blocks etc. shall be provided, as per

site requirements, for pipeline sections which are executed by normal trenching method.

g. The pipeline laying in this entire section, including all HDDs shall be planned and designed very carefully,

considering site conditions, existing constraints, presence of large water bodies and a running state highway

adjacent to the route with traffic. The planning and design shall ensure safe operation, construction and

installation of pipeline, without affecting the highway traffic and in view of the safety of public, adjacent

structures and installations and water bodies.

h. In view of the above, the entire HDD operation, including design, engineering, and execution and testing

shall be performed by a specialist HDD Contractor, with adequate experience and proven track record of

similar operations.

The Design of all HDD operations, including design of all materials, all engineering calculations, execution,

installation and testing etc. shall be carried out in full compliance to all applicable codes and standards, statutory

requirements and in line with project specifications and requirements. Best practices from the industry shall be

considered and followed where deemed suitable.

Design and engineering of HDD operation shall also ensure that no seepage of bentonite takes place from the HDD

into the adjoining soil / fields / fisheries / ponds etc. In case, any seepage happens, the compensation for the same

shall be done by the contractor.

concrete weight blocks. The preferred method for providing anti-buoyancy is by use of saddle bags and or concrete

blocks. Use of concrete coating shall be avoided and shall be followed only where use of saddle bags or concrete

blocks is difficult or not possible, due to restricted space, small ROU width or other limitations.

For Rocky River (if any) anti-buoyancy measures shall be provided with gabion arrangement.

The size & spacing of saddle bags and concrete blocks shall be determined during detail engineering. The thickness

of concrete coating required for each location class, is tabulated below. The size, weight and spacing of saddle bags

or concrete blocks shall be such that it provides equivalent weight and anti-buoyancy effect as provided by concrete

coating thickness (for each location class) mentioned below:

Based on Buoyancy calculations carried out for the Pipeline, the Concrete Coating thicknesses, to be used for 12” NB

x 38.0 km long Main Pipe Line, from Bantumilli to Ullamparru, shall be as below:

Crossing Location Class Wall Thickness of

Pipeline to be used
