Petkim, the leading petrochemical manufacturing company in Turkey, contracted Conbit to supply and exchange guy wires’ tensioners as part of their scheduled maintenance. They also asked them to develop the necessary structural engineering specification and project procurement.
In the Izmir province of Aliağa, the plant complex had a scheduled guy wire maintenance on the Ethylene-Arom flare stacks.
Conbit determined the exact length of the existing guy wires replaced by new certified guy wires, single part type.
They also did a site survey, measured the total station guy wire lengths, prepared method statements, logistics, and final tension report in preparation for the turn-over of the operation. The team also conducted NDT (Non-Destructive Testing) and professional inspections in advance.
For the operation, Conbit provided the structural engineering and the procurement and fabrication of turnbuckles and guy wires.
Combined with the design and flexibility, Conbit offered a unique service to its client.
Conbit exchanged and installed the new guy wires and tensioners using a DEMAG AC500-2 crane. The engineering of the guy wire lengths in combination with the required tension value was based on the temperature at the time of installation, a unique tensioning method.
Effective communication is key for Conbit working multiculturally on site. Completing the project on time is quite challenging due to wind conditions. Consequently, Conbit developed an alternative solution to installing some of the lower and shorter guy wires using wire rope access techniques.
The job was performed by IRATA rope access techniques, which required the standard wire rope access equipment. The project was performed by 13 crew members, including a team leader, rigger, first aider, IRATA rope access member, and technicians.
The project was initiated by installing temporary guy wires then replaced by new guy wires. Once installed, the temporary guy wires final pretension was removed and checked.
