After a human error, the boom of Crane-1 fell down to the deck during a routine maintenance procedure.
The boom was caught by the cargo runner, causing the boom to collapse halfway. As well as the serious damage to the boom chords, the boom head suffered significant damage as well.
Alatas was requested to conduct an incident investigation, assist during removal and repair, reinstallation and subsequent testing of the crane. We provided a Service Engineer who remained on-site during the whole duration of the project.
The engineer conducted the investigations, produced all needed reports and followed up during all stages of the repair. The engineer also served as the liaison between the client and their contractors for carrying out removal and was responsible for repair and installation and Alatas Crane Design – Alatas’ in-house structural design department.
