Conbit was requested to assist with the maintenance of the guy wires of the flare stack FL-5701, located on the Dung Quat Refinery in the Province Quảng Ngãi in Vietnam.
The maintenance of the guy wires consisted of the inspection of the guy wires, tension measurement, tensioning, verticality check, and greasing.
Frequent professional inspection and annual tension servicing and greasing are essential to ensure the structure's safety. It also prevent unnecessary repair and maintenance and prolong the service life of the wires.
The flare stack FL-5701 needed guy wire maintenance on 12 wires with a total length of ca. 1200m.
Conbit provided a complete package of maintenance services, including greasing and inspection. The greasing of the guy wires was done with wire rope access while visually inspecting them.
To perform the tensioning efficiently, Conbit engineers designed a hydraulic tensioning tool. The tension and angle deviations measurements were recorded and discussed with Conbit's back office in the Netherlands. They provided the project execution team with the right calculations and information to ensure the correct tension and project execution.
Besides guy wires maintenance, Conbit provided rope access rescue crew and maintenance activities on the flare stack itself.
This project is another example of a successful team effort between CR Asia and Conbit.
