1.0 INTRODUCTION
1.1 GENERAL
COMPANY intends to execute engineering, procurement, and construction (EPC) for Barzan Offshore
Topside and Pipelines facilities to develop natural gas reserves within the North Field located offshore
Qatar in the Arabian Gulf. The Project includes a natural offshore production system with conventional
wellhead platforms, intrafield pipelines, MEG pipelines, and power and fiber-optic subsea cables, as well
as export to the Barzan onshore Gas Plant located at RLC in Qatar.
The Barzan Offshore Project FACILITIES include three (3) offshore wellhead platforms designated BRZ-
WHP1, BRZ-WHP2, and BRZ-WHP3. Production from BRZ-WHP1 flows through a 32-inch diameter
Export Pipeline to shore. Production from BRZ-WHP3 flows through a second 32-inch diameter Export
Pipeline to shore. Production from BRZ-WHP2 can flow into either of the two (2) 32-inch diameter export
pipelines from BRZ-WHP1 or BRZ-WHP3 to shore.
Two (2) 24-inch diameter intrafield pipelines from BRZ-WHP2 connect to the two (2) 32-inch diameter
export pipelines at subsea tees located approximately 500 m from BRZ-WHP2.
Hydrate management is achieved by injecting mono-ethyleneglycol (MEG) into the production headers
on the wellhead platforms. MEG will be pumped through a 4.5-inch diameter pipeline from onshore to a
MEG supply header on BRZ-WHP2. MEG is then distributed through a 3.5-inch branch line from BRZ-
WHP2 to BRZ-WHP1 and through a 3.5inch branch line from BRZ-WHP2 to BRZ-WHP3 for injection
into the respective export pipelines as required. Figure 1.2 shows the general layout of the MEG pipeline
system.

4.2 MATERIAL TRANSFER & PREPARATION WORK
4.2.1 RECEIVING AND INSPECTION
Upon arrival of the pipe haul barge in the field, the HD-423 will bring the barge alongside to begin
offloading the pipe. The 32" pipes will be handled with wire slings wrapped by soft-rope to protect the
pipe coatings (Refer to BRZ-Q5B0-PL-1240 in Installation drawings), while the piggy-back joints will be
transported in bundles. The pipe joints to be used will be transported from the material barge to the HD-
423 and stored on deck until ready for use.
NOTE: The first layer of the pipe joints will be placed on wooden padding. And all base layered pipes
will be secured with stanchions on each side. Once removal of a single joint on the bottom stack is
made, adequate chocks will be placed to secure the stack.
All coated pipe and project materials will be received inspected and documented upon arrival on the HD-
423. The tally and inspection will be carried out as per the Quality Assurance (QA) and Quality Control
(QC) documents. The individual pipe information, heat number, length, etc., will be recorded on the tally
sheets and stored for final project documentation. A daily report which will contain a log of the day's
activities and recap of the tall will be generated.
NOTE: During the inspection process, damage to the pipe coatings will be noted. Any minor damage to
coating(s) will be repaired as the pipe is assembled. If the damage is assessed as major, the pipe joint
may be removed from the ready-rack and repaired at a later time.
NOTE: Pipe joints shall be not transferred when the lay barge is located on any subsea PL/Cable or
structure.
Concrete Coating Damage Repair 1) Spalling
Spalling damage shall be repaired if the damaged area exceeds 0.09 m2 (1 ft2), or if the depth of
damage exposes the reinforcing steel. Repairs to spalling damage shall be performed by the following
procedures, If the damaged area is 0.28 m2 (3 ft2) or less, remove the damaged concrete.
If the damaged area exceeds 0.28 m2 (3 ft2), remove the concrete from around the entire pipe
circumference throughout the length of damaged area. Restore the reinforcement steel, if necessary.
Wet the fresh surface of the remaining concrete coating at the point of coating damage for a minimum of
two hours.
Place the concrete repair mixture into and through the reinforcing steel until the surface is level with the
coating around the repair. Cure the repair.
2) Cracking
Cracks requiring repair are as follows:
Circumferential cracks that extend more than 180 degrees around the pipe circumference and are
greater than 1.6 mm (1/16 in.) wide
Longitudinal cracks that extend more than 305 mm (12 in.) along the pipe, irrespective of width.

without damaging the reinforcement steel Wet the crack surface for a minimum of two hours
Fill the crack with concrete repair mixture. Cure the repair
For FBE repair work, refer to V-PIPEP506-756, Quality procedure for Fusion Bond Epoxy coating.
3) MPI for MEG pipe
After loading MEG line pipe on HD-423 deck, all of MEG pipeline ends shall be conducted MPI as per
company specification before transfer to ready rack
4.2.2 LINEPIPE PREPARATION
1) Introduction of Linepipe
Each joint of pipe will be lifted from a stockpile location and placed upon a transverse rack at mid-ship.
It is here where the inside of the joint will be blown clean with a brush pig (or equivalent), with the
assistance of a tugger. Once complete the transverse conveyors will carry the pipe over to the first
longitudinal roller, this is where the bevelling process will begin."
Bevel Work sequence ;
- Both sides of pipeline bevelling machines
- Load the pipe on the ready rack
- Insert the bevelling tool into the pipe
- Bevel tool operator sets the machine to bevel the pipe.
- The Tool is rotated and the pipe is bevelled.
- Operator checks the bevel condition.

Pipe-Inside Clean Work
- Through the pipe inside, 1/2 wire is passed to the opposite side of the pipe. - Worker connects a wire to the cleaning tool and inserts the tool into the pipe. - Pull the tool by the winch located in the opposite side of the pipe.
2) Linepipe bevelling
The bevels of the pipe joints will be protected with bevel protectors, however, this does not always
prevent damage to the pipe's bevel. Further, to support the welding process, a compound bevel will
need to be made on the pipe-end, thus the process will begin at this first longitudinal track location. As
the pipe is progressed forward (to the bow) on the longitudinal roller system, the pipe is further readied
to assembly."
3) Ready-Rack
At the bow of the HD-423 is the area known as the "ready-rack". It is here where the pipe joints are
received from the longitudinal roller system, and any further completions of beveling will be performed.
This rack will stage approximately six (6) pipe joints ready to be introduced into the firing line for the start
of the welding process.
Also in the ready-rack area, the pipeline tally sheets will be completed, which will include the pipe joint
number, length, pipe material specifications, location of anode joints, etc. The tally man shall particular
attention to the sequence of the anode pipe joints to be loaded onto the conveyor system in order to
maintain the correct anode spacing along the pipeline.
4) Bead-Stall Operations
Once all pre-work is complete on each pipe joint, the joints are stored on the ready-rack. Upon the
completion of activities along the firing-line, the beadstall will be in need of another joint for introduction
into the process. The pipe is transferred from the ready-rack onto stalking shoes. The stalking shoe
operator will manipulate the pipe on the shoes/rollers so as to roughly align the pipe (diameter and seam
orientation) with the section of pipeline in the ramp's firing line.
After the rough alignment, the reach rod for the internal line-up clamp will be pulled from the joint
previously welded in the pipeline, and into the joint just roughly aligned. The clamps will be activated on
the pipeline side, and the stalking shoe operator will slowly end the pipe up to the pipeline. The spacers,
in conjunction with the stalking shoe operator will perform the required fine adjustments for final
alignment (high/low, root spacing, etc.). The clamp will be set, and readied for the welding process.
During these activities, the sequential pipe joint number will be painted on the end of the pipe joint

marine paint. The numbers will be at least 200-mm in height. Numbers shall be painted at the 9'-o'clock
and 3-o'clock positions."
4.3 WELDING & FILED JOINT COATING
4.3.1 WELDING
For the piggyback line welding station, the piggyback welding station shall be prepared as the drawing in
section 7.2.1.
1) Field Welding
After alignment of the pipe, the root bead and hot pass will be welded in the bead stall. Further, stalls 2,
3 and 4 will subsequently complete the welding process with fill and capping. In the tower, the welding
performance (and other stations) of the main line and piggy-back line shall be monitored for progress.
Once each process is complete in each station, a ready-light button will be pressed to indicate station
readiness to proceed."
2) NDT Station
After the weld is completed on a joint, all production welds shall be visually inspected and Ultrasonically
Tested (UT) for the main line, and Radio graphically Test for the piggy-back line. The COMPANY
representative and CONTRACTOR will monitor as the SUBCONTRACTOR will interpret the result of the
UT and RT. If the test is not satisfied with the QA requirements, the weld shall be repaired and NDT
shall be performed. The field weld joint will be inspected in accordance with the NDT procedure
approved by COMPANY.
4.3.2 TENSIONER
1) Operation Tension
As a part of normal pipelay operations, the barge tension will be continuously recorded and periodically,
the barge maintenance personnel will inspect the tensioners for hydraulic leaks, unusual sounds etc.
The field engineer will compare the proper tension, the pipe departure angle and depth against
information in BRZ-GX-O-PL-0507, PL1&PL3 Pipeline Field Data Book.
The tensions of tensioner & buckle detector are recorded on the recording system in the control tower.
The loads on the stinger rollers are monitored by load-cells and the stinger depth is monitored by
pneumo in the stinger cabin. The stinger operator will reside in the stinger cabin to monitor the loads on
the rollers and pneumo of stinger tip. And he will log the stinger pneumo and loads on the rollers every
10 minutes.
2) Buckle Detector
The buckle detector is used for pipelines to detect the occurrence of a buckle in the pipeline as the pipe
is being laid. It is pulled through the pipe when the barge pulls forwards and is located after the touch
down point.

The buckle detector shall have a pull force load cell with a constant display and continuous recording of
the load. Distance behind the laybarge shall be sufficient to ensure that the pipe is resting safely on the
bottom without buckle or other deformities
Normally a buckle detector is located a minimum 50m beyond the touch down point. Adequate wire will
be provided to ensure that the buckle detector rides approximately 5 joints behind the touch down point
of the pipe string. The field engineers will determine the length of the buckle detector wire by calculating
the distance of the pipeline touchdown point in addition to the 5 pipe joints. Buckle detector will be
inserted in presence of company representative and will be signed by him on the gauging plate. If the
buckle detector is pulled out at any stage during pipelaying for any reason, company representative(s)
on board to be informed prior to removal.
The Buckle detector tension gauge indicates more than 1 MT, pipelaying operation will be stopped and
then it will be informed to barge superintendent and Company rep to decide the recovery.

4.3.3 FIELD JOINT WORK
1) Field Joint Coating Stations
After each joint has been approved at the NDT station, the pipe will be pulled into the field joint coating
stations where various applications will be applied.
Prior to foam (HDPF) infilling, the surface has been carried out in accordance with Process Control
Procedure S/001/F/FBE. PS and has been accepted by the COMPANYs coating inspector.
The field joint shall be coated within four hours of blast cleaning or before the appearance of rust bloom,
whichever is the shorter. If there is evidence of rust bloom or if more than four hours has elapsed or the
blast is not in accordance with Sa 2 , the field joint shall be re-blasted in accordance with process
control procedure S/001/F/FBE PS. Whenever there is a stoppage on the production line, the blasted
field
Pipe will be blast-cleaned with grit or combination of grit and shot. The surface will then be heated to
correspond with the application temperature of the FBE powder, which will be circumference applied. Similar applications will be made for the piggy-back line as well.
For detail, refer to the BRZ-GX-O-PL-0636 Procedure for field joint coating and infilling work
Once the FBE coating is accepted free of defects, the HDPF will be applied to complete the field joint.
A pre-cut steel sheets with a 1-1/2 hole will be then wrapped around the field joint using intra-fuse.
Polymeric foam mixture from the injection pump is then injected into the hole to fill up the field joint. The
hole is then plugged temporarily for the foam material to set. The process described above is then
repeated for successive joints. The field joint coating detail for concrete coated pipe is as below.
For the Piggyback line and the non-concrete coated pipe, HDPF will not be applied.

6.0 CONTINGENCY PROCEDURE
This section details the various contingency and emergency response procedures.
6.1 ABANDONMENT
Temporary abandonment of pipelay operations may occur for a number of reasons; however equipment
failure and weather are the two most likely reasons to force a temporary abandonment. HD-423
Superintendent will assess the situation and determine if abandonment is needed. If conditions or the
situation allow, slow lay of the pipe will continue as long as viewed prudent by the HD-423
superintendent to do so. Company representative will be notified of any changes in the pipeline
production or pipeline.
When weather conditions are such that the barge or support vessels must cease operation, the pipeline
will be temporarily capped and placed on the seabed. This also applies when the weather forecast
indicates extreme weather conditions which would require the lay spread to depart location or otherwise
abandon normal operations.
In this case, the barge will lay out from under the pipeline by attaching an abandonment head to the
pipeline. All internal equipment including the buckle detector will be removed from the pipeline and the
head will be welded to the pipeline in the bead stall. The termination head will then be shackled to the
A&R winch wire.
Excess slack will be taken out of the A&R winch wire. The barge will then begin moving forward as the
tension is gradually transferred from the tensioner to the A&R winch wire. Lay tension will be maintained
throughout the procedure. The pipe-support of stinger will remain at the required depth until the
abandonment head has passed.
The length of wire paid out will be monitored and checked against the engineering calculations. The
barge will continue to move forward until the recommended length of wire has been paid out. The barge
will then remain stationary while excess wire is spooled off of the A&R winch. The survey team will
record the coordinates of the end of the pipeline for future recovery.
If the barge is to remain on location, the wire will remain connected to the abandonment head and to the
barge. The excess slack will be required to ensure that the movement of the barge due to sea state is
not transferred to the pipeline on bottom via the wire.
If the barge will be required to abandon the location, the A/R winch wire will be paid off from the drum. A
marker buoy will be attached to the end of the A/R winch wire for retrieval by the barge at a later time.
As an alternate, the pipeline may be laid on seabed and left without a buoy for recovery by the barge
using divers or ROV at a later date.
Step By Step Procedure for Abandonment
If, for weather forecast reasons, the decision to abandon the pipe is taken by the superintendent of the barge, steps are as follows; 1) Check and if necessary re-position anchor pattern for barge moving without anchor handling during

abandonment steps.
2) Finish all welds.
3) Recover line-up internal clamp and Buckle detector.
4) Weld the abandonment head, and NDT will be carried out. And the piggyback pipeline will be cut off
and supported to keep the gap for pulling head welding operation.(If required, the piggyback spacer
block behind the pulling head location will be installed after welding of pulling head to keep the
space for welding of piggyback pipe pulling head.)
5) Connect the A/R winch wire and spool the slack.
6) Transfer the tension from tensioner to A/R winch.
7) Once tension is transferred, fully open the tracks of tensioner to pass abandonment head.
8) Move the barge ahead until the abandonment head is reached to the last station of the barge.
9) The piggyback pipeline will be cut off and supported to keep the gap for pulling head welding
operation.(If required, the piggyback spacer block behind the pulling head location will be installed
after welding of pulling head to keep the space for welding of piggyback pipe pulling head)
10) It is recommended to keep the stinger in a median position while the abandonment head moves
from the laying ramp to the last roller of the stinger.
11) When the abandonment head leaves the barge, a pendant rope with a marked buoy is attached to
the abandonment head, and a mark is painted on the A/R winch wire at a distance equal to stinger
length.
12) As soon as the abandonment head leaves the stern of barge, start to adjust the stinger in a proper
position according to the results of stress analysis.
13) As soon as the abandonment head has left the stinger, stop the stinger operation and move the
barge ahead a predetermined distance as per the calculation for abandonment.
14) Pay out A/R winch wire by decreasing the tension of A&R winch until the pipe touches down on the
seabed. Then the wire is slacked and kept on board or released. If released, the wire is lifted with a
pendant buoy.
15) In all cases, the plotting of the barge route will be precisely made, in particular when the head
comes at the stern of barge.
16) If abandonment is required, according to the decision of the Barge superintendent, the stinger will
be disconnected or not.
6.2 RECOVERY
When weather or other conditions are better, the barge will prepare to recover the pipeline from the
seabed. For this procedure, the barge will be positioned over the abandonment location in the correct
lay orientation. The marker buoy on the A/R winch wire will be recovered to the barge.
Step By Step Procedure for Recovery
1) The A/R winch wire will be passed through the stinger, up the pipe alley and connected to the A/R

winch. The barge will now be moved ahead the minimum distance.
2) The barge will remain stationary and begin spooling in the A/R winch wire. As the wire tension is set
up the required lay tension, the barge will begin slowly back under the end of the pipeline while
maintaining this required tension.
3) The barge will continue back under the pipeline until the end of the pipeline is past the tensioners.
4) At this point, the tension will be transferred from the A&R winch to the tensioners. Once all the
tension is transferred from A&R winch to tensioners. When all the tension in A&R winch is
transferred to Tensioner, A&R winch wire will be disconnected from A/R head and A/R head will be
cut from main pipeline. The next joint of pipe will be ready to be welded.
5) If there is any piggyback pipeline, the A/R head of piggyback pipeline will be disconnected from A/R
head of main pipeline. And then the A/R head will be removed from pipeline.
6) Normal operations will commence at this time.
Dry Buckle
The location of the buckle and the extent of damage will be determined. The buckle will be surveyed by
ROV or Diver and a conclusion will be made as to whether the buckled area can be recovered to the
barge.
If the buckle will pass through the pipe-support and onto the barge, the barge will begin back under the
pipeline in the reverse process of laying pipe.
As the pipe joints come into the bead stall, they will be cut from the pipeline and set aside for re-
bevelling. As the buckled pipeline arrives in the line-up station of lay ramp, it will be cut out. The barge
will then begin stalking on the pipe joints and normal lay will resume.
If the buckle could not be passed through the pipe-support or recovered to the barge, the abandonment
head will be welded on the end of the pipeline. The pipeline will be laid down to the seabed as per the
termination procedures.
The barge will lift the pipeline alongside the port side by using the davits or by using a single point
pickup if possible. The buckle will be cut out and the recovery head will be welded on the pipeline. And
then the pipeline will then be placed on seabed and recovered as per the recovery procedures. Once on
the barge, normal pipelay will resume.
Wet Buckle
The location of the buckle and the extent of damage will be determined. In case, the buckle or damage
has allowed water to enter the pipeline, the pipeline will be laid on the seabed as per the abandonment
procedures. The buckle will be surveyed by ROV until it is determined that pipeline is fully flooded. Only
then can divers begin to work near the pipeline.
Divers will cut the pipeline at the damaged area. Divers will then insert pig stopper bars in the cut end of
the pipeline. Pipeline shall be air pumped in the end of the pipeline (shore side or start pulling head
location) so as to dewatering pig inserted in initiation head can dewater from start point to the damaged

area.
The pipeline will then be recovered to the barge as per the recovery procedure while pressurizing until
the buckled joint comes up to the surface.
Failure of Tensioner System
The tensioner will be checked and monitored regularly. However, tensioners have their own shut down
system for emergency case. Therefore if there is any unexpected situation occurred, tension will can be
kept until the tensioner is fixed.
If the situation requires that the tension on the tensioner needs to be released from the pipe, the A/R
head will be attached and connected to the A/R winch wire.
The tension will be transferred to the A/R winch and then the tensioner release the tension and then to
be fixed.
Failure of Anchors and Anchor Lines
HD-423 has 10 anchoring system, and for pipelaying operation only 8 anchor systems will be used.
Therefore if there is any failure of anchor lines and mooring winch, other mooring winch will be used.
However, once if any failure of anchoring system is found, the pipelaying operation will be stopped.
The detail procedure for anchor winch trouble and anchor line failure will be described in the Anchor
Handling Procedure.
Breakdown of positioning system
Once the positioning system is broken down, the laying operation will be stopped and then be waited
until it is fixed.
Piggyback Pipeline and Cable Contingency Procedure
Piggyback Pipeline Contingency Procedure
In case temporary abandonment is required during pipelaying operation piggyback pipeline will be also
abandoned with following sequence.
While the A/R head is welded in the line-up station, the piggyback pipeline will be cut, and temporary
A/R head will be welded and bundled as the Tee joint case in BAZ-Q5B0-PL-1331 in section 7.2.2.
When the abandonment condition is completed, the recovery operation of piggyback pipeline will be
done with main pipeline.
And the main pipeline is arrived in the line-up station, the temporary securing will be released and A/R
head will be cut out, and then welded to the end of coiled pipe.
If there is any damage to the pipe coating, the coating repair will be done according to the coating repair
procedure, FBE and concrete coating procedure which will be submitted by vendor.
