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.

Coupling Joint is a flexible joint system.
Allows preliminary check for each joint under water

Manufacturing Meeting, Spain, January 2005
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.

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

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
