2023 2nd Alert Hipo#34 Crane tipped over.
Approximately at 08:20 am, the crane (GROVE, 4W-All Terrain 30T) was spotted outside of the location (approximately 16.3 meters away from the tea-room trailer) while the mechanic went to bring the grease gun. The Crane operator had extended the crane boom fully at approximately 30 degrees without extending the outriggers which led to weight imbalance and the crane tipped onto one side and rested with its top-end boom into ground level. The Crane operator was able to exit the crane safely without any injuries.
Rig Manager to ensure Musta’ed is effectively implemented in all activities including sub-contractors out of sight activities. Crane Operator to extend the outriggers before operating the boom. Rig Manager to ensure all third-party activities/tasks are to be discussed and approved prior to start even if it’s planned to perform outside of the location. Rig Manager to ensure 3rd party maintenance crew have task-specific SOP prior to approving the task. Ensure cranes are having Interlock system installed so that the crane boom can not be extended without extending the outriggers Do not operate/extend Crane Boom without outriggers are fully extended.
Inadequate work planning to perform crane maintenance work. The crane operator did not extend the outriggers prior to operating the boom. The area was neither designated nor prepared for the task. The activities were performed without notifying the Rig Manager. No meeting was carried out between the Crane Operator and Mechanic to discuss the correct steps to do the task. Inadequate oversight of subcontractor's activities on site.
