Paradigm Shift
Modern wire ropes (including multistrand and IWRC ropes) frequently fail from internal deterioration without externally visible signs.
This situation makes prevalent ‘rag-and-visual’ inspection methods unreliable and outright dangerous (http://bit.ly/2H7bA7X, http://bit.ly/2PUPuJV).
In contrast to sole visual inspections, our MRT instrumentation will reliably detect and evaluate internal and external wire rope deterioration (http://bit.ly/2Y2CEw9, http://bit.ly/2Wzmjil).
Hence, wire rope examination/evaluation (NDE) procedures are going through a major PARADIGM SHIFT:
- MRT NDE will become the indispensable and primary wire rope inspection method. For extremely safety-critical applications, continuous rope monitoring systems (CRMS) will become mandatory (http://bit.ly/2V8eGgV, http://bit.ly/2H4rMZ4).
- Visual Inspections will be a minor – albeit important – complement of MRT NDE.
- Auxiliary information on rope construction, operating conditions, damage mechanisms and failure modes, rope history, etc. is an important component of a complete wire rope NDE.
This PARADIGM SHIFT is described in my memorandum titled “Wire Rope Inspection: NEW PARADIGM”.
