Currently, the timely identification of improvements, shortcomings, and potential failures applied to maintenance has taken relevant attention from the scientific community in recent years. In order to carry out appropriate diagnosis, the employment of methods to properly measure the reliability of industrial processes has been a trend. In this work, AMORMS and AMS-ISO 55001 are applied to a seawater desalination plant aiming for carrying out a fitted measurement, generating suited improvement plans. In this context, AMORMS is a model based on 8 phases, which focuses on assets management. On the other hand, AMS-ISO 55001 focuses on the asset management norm ISO55001. The results yielded include the design and generation of actions to tackle the 20% more deficient categories needed to achieve a competitive industrial performance.
