Site Supervision service

If any request or any requirement, field supervision is provided to achive a

satisfactory installation. Field engineers and technicians can advise the

purchaser or the installer to help him achieve a satisfactory installation.

• Field engineers supervise the installation of GRP pipes,

• Follow the errection closely and submit their comments and recommendations

to achive satisfactory pipe installation,

• Assist to the installer for decision of installation technics and applications,

• Assist to project firms for computation and determination of thrust block

dimensions,

• Field technicians assist the workers to achieve satisfactory coupling joint and

backfilling.3


Subaqueous Installatıon of GRP Pipes

GRP pipes are used for subaqueous applications such as;

Waste water outfall,

Cooling water outfall,

Sea water intake for

Drinking water supply,

Cooling water supply,

Etc...

Submarine crossing.

GRP lock couplings allow angular deflections.

Pipe Joint Systems

GRP TEST COUPLING JOINTGRP TEST COUPLING JOINT

Coupling Joint is a flexible joint system.

Allows preliminary check for each joint under water

5


Depending on pipe diameter two, three or four pieces of marine harness lugs are fixed surrounding the ends of the pipes.

It is recommended to remove stud bolts before backfilling in order not to prevent flexibility of GRP couplings.

MMarariine ne HHarness arness LLugug

Marine harness lugs are used to keep together preassembled pipe strings of several pipes during loading, transfering, and sinking operations and also to assist divers for joining operation under water.

Steel lugs are fixed with filament winding method using glassfiber &resin

Trench Excavatıon & Backfıllıng

- Excavator, dredger or trencher is used for excavating the trench.

- Excavator or clamshell bucket or flex tubes are used for backfilling.

Subaqueous Installation Techniques

Single pipe installation

Multiple pipe installation

Multiple pipe installation, providing pipe string

Depending on project requirements and site or weather conditions different installation techniques are used.

10


Joining of Pipes under Water

Generally, come along jacks with steel clamps are used for joining of pipes.

Depending on marine conditions marine harness lugs are used to join the pipes under water.

11


Pipe Alingment while Joining

Depending on project reuirement, marine and weather conditions different equipments are used for alingment of pipe ends to join.

Trench Backfilling

Excavator or clamshell bucket or flex tubes are used for backfilling.

Backfilling is provided by the divers under water.

13


Long pipe sections (100m-300m-500m...) are preassmbled on land or barge and lowered to water and joined under water.

MULTIPLE PIPES PROVIDING PIPE STRING


14


TOW Techniques

• Controlled depth tow

Depending on shape of the sea bottom, weather conditions and adequacy of equipment different tow methods can be selected.

• Surface tow

float and sink

sub surface tow

bottom pull

off-bottom tow


Onshore-Offshore Transition Zone

Sand bags may be used to prevent floating of pipes and washing out backfill from wave actions.

Onshore-Offshore Transition Zone

Pipes are launched to the sea with different methods as shown on the pictures.
