Failure Analysis on the Wire Rope for Lifting Equipment

The failure analysis o the wire rope for the lifting equipment is the project based on the
real life case study. The lifting equipment is the pedestal crane that widely used at the
offshore facilities. This report contains the detail explanation on the project. The
objective of this project are to find the factors that lead to the failure and to find the best
practice on handling wire rope for safety and to reduce the downtime of the pedestal
crane due to wire rope failure. The methodology conducted to complete the analysis
divided into four main sections which are research, sample preparation, experiments and
testing and final analysis and conclusion. The failure analysis conducted is based on the
failure analysis procedure that involved non destructive testing, mechanical testing,
macroscopic and microscopic examination, metallography, and energy dispersive x-ray.
The results from the experiments and testing indicated that corrosion on the internal part
of wire rope reduce the wire rope strength by 53.81%, the wire rope experienced ductile
fracture, the damage of the wire rope start with the wear and corrosion of the zinc
coating before finally failed. As a conclusion, the failed of the wire rope occurred due to
the corrosion that reduces the strength of the wire rope.
