What caused the Bayan Lepas cable bridge to fail under load?

Question

Accepted Answer

The Bayan Lepas cable bridge failed due to structural inadequacy to bear the weight of the 275kV cables.

The collapse occurred at Cable Bridge number one in the Motorola company area, which is part of the project leading towards Intel. Tenaga Nasional Berhad (TNB) has since taken steps to rectify the situation, including removing the cables, recommencing cable installation, and reinforcing the bridge structure.
Structural Failure Due to Cable Weight

The primary cause of the Tenaga Nasional Berhad (TNB) cable bridge's collapse in Bayan Lepas was its inability to withstand the load imposed by the 275kV cables. The structure at Cable Bridge number one, located within the Motorola company area and serving the project route towards Intel, succumbed to the weight of these cables.
Immediate Remedial Actions Undertaken by TNB

Following the incident, TNB initiated prompt corrective measures. These actions involved the removal of the cables from the collapsed structure and the subsequent reopening of the cable installation process. Furthermore, TNB has committed to reinforcing the bridge by adding piling in the centre to enhance its load-bearing capacity.
Communication and Project Resumption Timeline

TNB has formally notified Intel of the issue and the subsequent remedial actions being taken. The project, which involves the installation of the 275kV cables, is slated to resume its operations at the conclusion of November. This timeline indicates the expected duration for the necessary repairs and structural reinforcements to be completed.
