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.
