Flowline Buried Underuround Section

4.3.1

Excavate trenches 450 mm wide to give a minimum of -m pipe

cover from compacted ground level for the required footage of

welded pipe, including risers and other pipe fittings.

4.4

Flowline Burial Criteria

Clean, prime, coat, wrap, lower into trenches the required footage of

welded and radiographed pipe. The flowlines shall be buried along the

flowlines route in accordance with the following:

a. All sections passing alonglthrough the overhead power

transmission lines areas.

b.

Along any main road or at asphalted road crossings.

c. At desert road crossings.

d.

In the vicinity of existing well sites.

e.

Beneath the existing flowlines and gas lines.

f. Close to RCV manifold of respective gathering centre.

g. Across oily and/or gatch top road crossings.

h. Other areas as detailed on drawings.

i

Hydrotest the buried portion of the line for

6

hours.

j Upon Company acceptance of the hydrotest, perform the following:

1

Reinstate the line.

2. Backfill all the trenches.

4.5 Flowline As~hal ted oad Crossing

4.5.1 Prepare necessary welded, inspected, coated and wrapped

12.75 n. OD pipe sleeve section of road crossing together wi th

2-in, breather pipes.

4.5.2 Prepare road diversion of similar width t o crossing.

4.5.3

After completing the road traffic diversion s) and all necessary

safety requirements, the Contractor shall cut the road for a

suitable width and install the required number of pipe sleeve

crossings. T w o numbers of pipe sleeves are t o be instal led at

each crossing: one for th e flow line t o be instal led and one spare.

Excavations for the above wo rk shall be suff ic ient ly deep up to

3 m) so that the top of the sleeve pipes shal l be at least 1 m

belo w the compacted ground level.

4.5.4 Install the prefabricated pipe sleeve installations and breather

pipes so that they shal l extend 3 m clear on each side of the

exist ing w idt h o f the road shoulders.

4.5.5 After welding, radiography, coating, wrapping and inspection,

insert the flow line pipe through the pipe sleeve. Instal l matc hing

pipeline casing insulators at 1.3-m intervals, all along the length

of l ine pipe installed inside the pipe sleeve.

Flow line Tie-in at Gatherina Centres

4.6.1 Construct f lowl ine t ie- in to the RCV m anifo ld at the respective

gathering centre. The flowline shal l be conne cted t o a RCV

man ifold point wh ich shal l be specified on the D rawings or onsite.

4.6.2 If required, f i rs t expose the old l inel l ines for about 75 -m length

upstream of RCV tie- in point. Then cu t the old l inel lines 2 -3 m

belowground, blank off and cap the old l inel l ines by welding.

Remove al l the cu tou t piping along w ith old r iser. The n ew ly laid

f lowl ine shall then be connected t o the same RCV manifo ld point

throu gh a n e w underground section and riser.

Wellhead Ho ok UDS

4.7.1 Wellhead Manifold

Fabricate as required a dual- or single-wellhead manifold and/or

m odify th e existing single to du al wellhead m anifold.

4.7.2 Surface Safety Man ifold

Fabricate as required a dual or single surface safety manifold,

and/or m odify the existing t o dual surface safety manifold.

8/15/2019 015-IH-1009 (Flowlines)


4.7.3 Tie-in of Wellhead and Surface Manifold to Flowline

a. Lay, string and weld approximately 100 m of 4-in. or 6-in.,

Sch-80 or Sch-40 pipe between the wellhead manifod and

surface safety manifold, and connect the two manifold to

the newly laid flowline.

b.

Clean, prime, coat, wrap, lower into trenches welded and

radiographed pipe as above. Then, backfill the trenches.

4.7.4 Burn-Off Pit BOP) Line

a. Lay, string, prepare for welding and weld approximately

300 m of 4-in., Sch-40 pipe.

b. Excavate 450-m wide minimum) trenches to give a

minimum of 2-m pipe cover for a total of approximately 75

m.

c. Clean, prime, coat, wrap, lower into trenches

approximately 75 m of the BOP line, and then backfill the

trenches. The remainder is to be laid on surface.

d. Connect the BOP line to the surface safety manifold.

e.

Route the end of the BOP line, through a BOP 12

m

in

diameter with the surrounding 3-m-high gatch wall.

4 8

lowline Pioeline Markers

Install pipeline markers and signs every 500 m throughout the length of

the flowline, whether buried underground or elevated on supports. In

addition, install pipeline markers and signs wherever the flowline enters

the ground and wherever

t

reappears aboveground.
