Abstract

This discussion paper outlines a new and innovative concept that addresses the issue of maximising both asset life and reliability through the use of a quality assurance-based methodology. The concept collates the progressive cumulative effect of combining the individual tools of ‘best practice’ techniques and appropriate responses to underlying failure mechanisms, presenting them instead as delivering an integrated spectrum of outcome quality. Against this outcome, one may balance aspects of remaining strategic risk, the cost of performing the process to a given level of quality, and the time burden to do so.
Focusing on cable management on this occasion, the methodology offers promise for application to all sectors of Power Industry asset management and will be progressively developed in that regard.

“Old cable management practices were fine in their day but they certainly
will no longer achieve the desired reliability and service life outcomes
with MV XLPE cable!!”
