Purpose of Job

1. Responsible for rotating equipment health and performance assessment, utilizing multiple condition and performance monitoring techniques and technologies, to reduce unintended downtime as well as to restore, maintain and/or improve equipment integrity, reliability, and efficiency. 2. Consolidate, analyse, and interpret unique, Sasol-specific combinations of equipment types including pumps/compressors/steam-and gas-turbines/electric motors/gearboxes, train components including couplings/bearings/seals, their unique materials of construction, manufacturing and repair processes, and associated failure mechanisms so as to conduct an in-depth engineering assessment and provide an integrated view of the design principles, component limitations, influential factors on operation, risks associated with off-design operation or poor condition and thereby be able to provide sound assessment on equipment remaining life and assess feasibility of proposed modifications. 3. Set standards for the operation, maintenance, and optimization of turbo machinery across all Sasol sites and apply specifications and standards for procurement and installation of equipment and related systems. 4. Provide technical expertise and governance to implement continuous improvement and best practices for turbo machinery at the lowest life cycle cost across all Sasol sites. 5. Be strong proficient in applying digitalization tools e.g. machine learning, mathematical modelling and programming to every aspect of your work in advancing Sasol’s rotating equipment assets in the Industry 4.0 era. 6. Be strong proficient in applying the first principles of fluid mechanics, thermo-, aero- and rotor-dynamics across the specialist fields of tribology, gas compression, fluid and structural simulation and vibration analysis. 7. Be familiar with the various rotating equipment condition monitoring techniques and technologies such as vibration and oil analysis and how best to apply them on each asset type to troubleshoot events/faults/deviations and further provide an accurate diagnosis and prognosis for remediation. 8. Be familiar with the various rotating equipment design-by-analysis tools, including Finite Element Modelling (FEM) and Computational Fluid Dynamic (CFD) analysis, how and when to apply them and have a good understanding of interpreting and validating the results. 9. Be familiar with engineering asset management tools, techniques and metrics including Failure Modes and Affects Analysis (FMEA), Mean Time Between Failures (MTBF), Mean Time To Repair (MTTR), Condition Based Maintenance (CBM), Relibaility Centred Maintenance (RCM) and Root Cause Failure Analysis (RCFA), how to apply them during incident and failure investigations, and be involved in specifying the correct equipment maintenance and reliability strategies to improve equipment Reliability and Availability.

Key Accountabilities

Business Results: Improve rotating equipment condition monitoring and diagnostics to enable asset prognostics by: 1. Compiling and deploying comprehensive health and performance dashboards for rotating equipment to enable business asset line of sight, improve Operations & Maintenance decision making, enable accelerated fault analysis and identify deviations (opportunities for optimization) 2. Driving the appropriate use of and combination of Condition Monitoring and Condition Based techniques to optimize (time and cost) asset strategies on rotating equipment components to result in improved reliability, availability and performance. 3. Providing guidance and governance with regards to operation and maintenance of turbo machinery to ensure best practices followed as well as compliance with world standards and Codes. Enable Turbo Equipment Operations and Maintenance to extract maximum asset value through safe and sustainable (stable, reliable) operations, cost effective maintenance, increasing output or reducing cost/energy waste by: 4. Providing critical rotating equipment operating envelopes to define operational and mechanical/vibration limits to support deviation management through identification of off-design operation and providing remediation or mitigation actions. 5. Identifying, communicating and issuing recommendations regarding equipment integrity non-compliance, deviations following inspection and condition assessments to improve quality and ensure cost-effective maintenance. This will include amongst others: o Issuing of engineering memo’s, supporting NCR’s and concessions, improve equipment maintenance Quality Control Plans, compiling Scope of Works and Technical Specifications for refurbishment, new procurements and upgrades. o Support Rotating Equipment General Overalls and Turn Arounds through equipment inspection and evaluating scope of repair/replacement and providing the appropriate guidance accordingly for complex repair procedures, fit-for-service assessments to defer high capital replacements, advise technology investment where necessary. o Support the improvement of critical pump MTBF’s through investigating and identifying contributing factors to failure/lack of performance and direct preventative or optimization actions towards Ops and Maintenance 6. Identifying, developing, motivating and executing life extension strategies through engineer-out opportunities, improved maintenance practices, refurbishment, renewal, re-rating, re-design, retrofits, fitness-for-service, etc

Key Accountabilities Continued

 7. Supporting capital/renewal/RCP projects for rotating equipment through taking responsibility for front-end loading of discipline-specific projects through providing deliverables such as technical justification or opportunity definitions, fulfill the Engineering track representative on selective discipline-specific projects and provide input towards road maps for asset renewal or optimization. 8. Identify and manage risk associated with zero-graded equipment, statutory-overdue equipment, complex engineering repairs, etc 9. Input into RBI on turbo machinery and associated systems and components (incl vessels and piping) Provide suitable and data-driven engineered analyses results and solutions using innovative technology and fit-for-purpose practices during reactive (failures, incidents) and pro-active/prediction events to position Sasol of the Future in reaching its Ambitions of energy efficiency and emission reduction by: 10. Continuously developing and applying FEA/CFD/Hydraulic/Modal/ Aero-Thermo/Rotor dynamics modelling and simulation on reverse-, re-engineering, design or modification analysis opportunities. 11. Develop engineering calculation tools to assist in accelerated CM assessment, quantify impact of machine or system modifications and enable verification of technical solutions provided by OEM’s and Service Providers Leadership, values behaviour, personal development people engagement and enablement: • Be accountable for personal development and managing own performance in a professional manner with focus on quality and accountability. • Manage engineering knowledge by transforming, packaging, transferring, maintaining, and improving engineering knowledge in-house. • Contribute to EIT/rotation/vacation engineer’s development through coaching and mentoring. • Continuously strive to develop own engineering skills and competency through attending relevant industry events and courses, providing field-specific training to operation’s engineers and maintain current technologies while exploring for future technology investment. • Demonstrate a corporate leadership role via involvement and influencing in different strategic forums in Sasol e.g. Steercoms, Improvement forums, CoP’s, CoE’s etc. • Integrate across functions such as Maintenance, Production, other Engineering disciplines within the Sasol SA sites as well as across Sasol companies including Secunda Operations, Sasolburg Operations, P&E, Pipeline Operations etc. Relationships, teamwork and collaboration: • Manage and leverage existing internal and external relationships, and create new networks, to utilize opportunities and improve technical and industry collaboration to the benefit of Sasol by influencing strategic direction and enable sound decision-making. • Maintain/develop conducive relationships with including OEM’s, RE service providers, RE strategic sourcing/procurement, ROAS project portfolio and BD team, Operational (Production AM/SM/VP) and Maintenance (AM/SM/GMR2.1/2.7) entities at TEM/Komati/Sasolburg/Natref on rotating and asset health related matters, Sasol digital and data science teams, Engineering disciplines incl. electrical/Process/I&C/mechanical/civil.
