Nihar Associates was employed to provide day-to-day reliability and maintenance support for our client’s alumina refinery.

Nihar Associates’ engineers were permanently based at the refinery and were able to eliminate a number of long term reliability/maintenance issues during their time there. In addition, Nihar Associates:

  • Identified all changes that needed to be made to the maintenance strategies, plans, and spares for the entire refinery and associated mines during a 260m capital development project.
  • Developed a risk-based approach to develop maintenance for tank farms using Nihar Associate’s proprietary TIMS (Tank Integrity Management System) software. The software uses a sound methodology to manage and report on more than 600 tanks.
  • Conducted an exhaustive Failure Modes, Effects and Criticality Analysis (FMECA) for the port silos.
