1 An Asset Management strategy that yields results Obbie Lephauphau Principal Engineer: Asset Management Engineering Support Services Sasol Mining

2 Sasol Mining Background Sasol Mining is a division of Sasol Limited Consists of six mines, two plants & Central workshops Together they produce and handle about 43 million tons of coal annually

3 Underground Mining method- Board and Pillar extraction

4 Overview of critical underground Assets

5 Overview of Surface Assets

6 Asset Management definitions Coordinated activity of an organization to realize value from assets ISO Systematic and coordinated activities and practices through which an organisation optimally and sustainably manages its assets and asset systems, their associated performance, risks and expenditures over their life cycles for the purpose of achieving its organizational strategic plan PAS55

7 Fundamentals on which asset management is based Bringing value for the organization and all its stakeholders from the use of its assets Promoting alignment across the organization to achieve organizational goals Managerial Leadership with commitment, along with an empowerment culture Achieving Assurance of producing required asset performance

8 Key themes (PAS 55 & ISO55000) Alignment ( line of sight ) of organisational objectives feeding clearly into asset management strategies, objectives, plans and day-to-day activities Whole life cycle asset management planning and crossdisciplinary collaboration to achieve the best value combined outcome Risk management and risk-based decision-making The enablers for integration and sustainability; particularly leadership, consultation, communication, competency development and information management

9 Asset life cycle

10 Percentage of the life cycle cost Significant life cycle cost are committed during asset creation phase Life-cycle cost reduction opportunity Committed cost (Cumulative) Actual Life cycle cost Asset Creation (Asset Design and development, Production and/or construction) Operation and Maintenance Asset Disposal

11 Process for acquiring new assets

12 Asset replacements or upgrades requires a business case Maximize Return on Investment Mitigate asset-related Risks Reduce asset-related Costs Improve asset performance Improve reliability Ensure regulatory compliance Improve environmental and human safety Reduce maintenance cost Extend asset Life Increase labour utilisation Reduce running cost Reducing operating downtime Increase asset output Improve asset efficiency Reduce Inventory

13 Life Cycle Costing is used for Asset Replacement decisions Achieving reduced Total Cost of Ownership, Reducing operating cost surprises, development of common objective criteria to be used. Providing a mechanism identifying major cost drivers to be targeted and optimized and maximizing the value of the asset over it's life.

15 Accum. Maintenance Cost Mitigated production loss and maintenance cost are used to justify asset renewals or overhauls cost 100 Life Cycle Maintenance Cost TTR without interventions TTR with interventions 0 0 Asset Life (Tonnes) 6 First CM life before 2Mt Millions Current Maintenance Profile Cost with with Overhauls interventions Poly. Maintenance (First CM Cost life before Without 2Mt) interventions

16 Optimal renewal or overhaul cycles are determined by economic life cycle Maintenance Cost Production Loss Renewal or Replacement Capital

17 ROCOF per day Performance of the renewal or overhauls is measured Rate of occurrence of failure (ROCOF) per day Overhauls Tons in Millions Asset life Cycle in tonnes

19 Individual asset management plans are prioritised and compiled into portfolio asset management plan

20 Asset management plans are communicated to stakeholders in a format, and appropriate level of details
