The system can also be used to detect faults, allowing for quicker repair and cutting down on the need for manual equipment inspections. Maersk's end goal now is to use big data analytics for predictive maintenance to prevent faults. Before RCM, all containers would go through extensive and costly inspections. The use of smart sensors makes it possible to know the condition of the reefer precisely, and helps to determine the type of inspection required prior to release for export.
