Malongo IT Tower Removal

Project Overview

Chevron Angola approached Conbit to engineer a safe solution for removing a severely corroded section of an IT tower located in Malongo. The tower, standing over 40 meters tall, had a compromised top section above 30 meters, 16 meters in total, that was no longer safe to access or maintain.

Conbit was responsible for designing and implementing a custom access method, enabling technicians to reach and remove the deteriorated portion of the structure without compromising safety.

Method

To make the upper section of the tower safely accessible, Conbit engineered a tailored access tower. This structure provided secure anchor points for rope access technicians operating above 30 meters.

Key features of the access system included:

• Capacity for a maximum of two technicians working simultaneously above 30 meters.
• Construction using modular aluminum L-struct lattice sections.
• Rigged and stabilized using chain hoists, slings, and Tirfor winches, all anchored to structurally sound areas of the original tower.

Removal was carried out using handheld tools such as angle grinders and saber saws. Each dismantled piece was securely lowered to the ground using rope access equipment.
