Currently, the Mill area treats up 200,000 – 250,000 tonnes per day, which making it as one of the largest <br /> <br /> <br /> <br /> concentrating circuits/facilities in the world. This plant infrastructure was also consider as the main vital <br /> <br /> <br /> <br /> core of mining operational process in PTFI area which nearly 80 million tonnes of ore are processed per <br /> <br /> <br /> <br /> year at average milling rates. <br /> <br /> <br /> <br /> <br /> Wet moisture and oxygen regenerate conditions that make oxidation occurred faster. Finally, as a combining <br /> <br /> <br /> <br /> consequence of the facility age and the environmental circumstance mentioned previously, PTFI’s existing <br /> <br /> <br /> <br /> structural facilities have suffered from extensive corrosion problem over the years. Even more, those <br /> <br /> <br /> <br /> corrosion issues have also been put as one of Mill Concentrating Division’s Safety Top Risk for the last 3 <br /> <br /> <br /> <br /> years (2014 – 2016). Bending, loss of thickness or crack is the worst effect caused by corrosion. The latest <br /> <br /> <br /> <br /> worst experienced by PTFI related with corrosion impact was occurred this year (Aug, 2016), when a Mill <br /> <br /> <br /> <br /> electrician was carrying out troubleshooting maintenance work on power cables located in an overhead <br /> <br /> <br /> <br /> cable tray. The employee was fell approximately 9 meters onto the concrete floor below the work area after <br /> <br /> <br /> <br /> the cable tray (which indicated was rusted/corroded) collapsed under the heavy load and the victim sustained <br /> <br /> <br /> <br /> fatal injuries. Fatality accident is intolerable at all, it is priceless and become an ultimate lost for the <br /> <br /> <br /> <br /> Company from any of all perspectives, and specifically in terms of PTFI Safety Standard compliance. Thus, <br /> <br /> <br /> <br /> Corrosion Control (maintenance) works are significantly required to be conducted as appropriately. <br /> <br /> <br /> <br /> <br /> The sequence plan implementation and the performance management system to measure the corrosion <br /> <br /> <br /> <br /> control progress are finally become the two most critical and crucial issues to be caught up in regard with <br /> <br /> <br /> <br /> the fighting of corrosion speed in this enormous area within the Mill Concentrating Plant itself. This research <br /> <br /> <br /> <br /> is significantly require to measure the current performance of corrosion control works which have been <br /> <br /> <br /> <br /> done previously and also for the works which currently still being completed using the Integrated <br /> <br /> <br /> <br /> Performance Management System (IPMS), as a novelty hybrid PMS model which seeks to improve the <br /> <br /> <br /> <br /> earlier research models with the implementation of Knowledge Based expert methodology system. This <br /> <br /> <br /> <br /> approach can assist in identifying and prioritizing the key decisions that need to be actioned to overcome <br /> <br /> <br /> <br /> the existing PMS shortcomings, so the main challenge for managing the performance of Company’s assets <br /> <br /> <br /> <br /> in terms of its strategies (excellent safety performance, efficient cost, effective people and organization, <br /> <br /> <br /> <br /> achieve production target and appropriate working environment) can be achieved as optimally. <br />
