Application of MFL nondestructive testing for automated rope condition monitoring

摘要

Continuous rope monitoring is a new emerging application of rope NDT. It allows increasing safety of rope installations, which is especially important at dangerous industrial objects such as drilling rugs or mining shafts. At the same time their design and implementation makes to solve several problems, which are not actual for traditional MFL equipment. First of all monitoring systems should be have rugged designed and be able to work in severe working environment (high and low temperatures, high humidity, dust, vibration action) with minimum servicing needed. Secondly it should give a maximally easy to interpret condition indication, for example, as traffic light indication, so that it does not claim some special qualification of service personnel. Thirdly it should be based on automatic processing of representative measurement data. There is a row of some additional features, which distinguish MFL equipment for continuous rope monitoring. These questions are discussed in the report in general and for the case of drilling rig rope monitoring.
